Weston Stucco Repairs TorontoStucco siding is a beautiful addition to any home or business. While it's meant to hold up for years to come, you may occasionally encounter problems with cracks or holes in the stucco. These will need to be repaired right away. If left unrepaired, stucco damage can cause leaks and lead to further deterioration in the siding. Because stucco is a textured surface and unique, it always poses a challenge to anyone looking for a DIY solution. But stucco repair, done right, by qualified professionals, can make your stucco siding as good as new.
The most common stucco repair of all is moisture. Because exterior siding is so exposed to all elements of weather, you may occasionally encounter problems where stucco may crack, cause holes, or even need to be resurfaced. Cracking is due to structures settling, and if left unrepaired, it can often lead to blistering. Holes in stucco can occur, as well. Though not as common as cracking, holes can occur because of something hitting the stucco and causing damage. Because they leave the entire area exposed, you want to get these repaired right away. Sometimes, resurfacing may be the best answer to your stucco problems, particularly if the stucco has seen its share of years or if the stucco is deteriorating in several places along a surface. In this instance, an entirely new surface is put in place of the old. This approach can solve any problems you are having with blistering, holes or cracking, and is a long-term solution. Don't try these repairs yourself. You want to call in a stucco expert, someone with years of experience and answers to all of your stucco concerns. They are best able to offer you the right solution for your every stucco problem. Stucco keeps your home cool in summer and warm in winter, is easy to clean and maintain, and looks great.

Why Stucco Cracks Several factors can contribute to the stucco cracking over the years. Stucco is generally laid over metal lath, which, while sturdy for construction, is susceptible to the elements and can rust over time. Stucco is very heavy, and when the metal lath rusts, the weight of the plaster causes the stucco to let go and can result in cracks. Another cause of cracking stucco is that it is often installed without the appropriate expansion joints. Stucco expansion joints relieve the stress of the thermal expansion and contraction of the stucco, as well as the natural shrinkage which occurs while stucco is curing. Finally, a leading cause of cracked stucco and likely the most severe is failing flashing or caulking. When stucco cracks for this reason, it is imperative that you act fast to repair it, as it means that water is penetrating your stucco exterior. Small cracks will quickly become large cracks, and before long, you will have a mould issue, which can be detrimental to your home and your health. The Solution: Our stucco restoration experts will visit your home or business to assess the damage and determine which of the issues mentioned above you’re experiencing. If the cracks in the stucco are small and the integrity of the cladding itself has not been compromised, we will be able to patch the cracks. This is achieved by applying a base-coat of cement and epoxy with a 4.5-ounce fibreglass mesh. Once that has cured, we will use a colour coat to ensure that the appearance of your stucco is seamless and there is no remaining evidence of the cracks. Alternatively, if your stucco issues are more severe and the integrity of the wall itself is at risk, we will replace the entire panel. We’ll first tear down the existing stucco in a safe manner and then replace the wall either with traditional stucco or with EIFS. As with any project we undertake, A & N Exterior Stucco will always visit the site first and provide a free on-site estimate.

If you dare to paint the upper sash of your windows closed, every owner of the house that follows you will curse your name. Probably multiple times. And the owner who finally decides to get that sash open again will curse you double. I was that double-cursing owner. I long ago stripped and refinished the bottom sash in my bathroom window. The upper sash was firmly painted closed, so I put off dealing with it for years. Well, this was the weekend when I decided that the sash would open. My bathroom does not have a fan, so air flow is pretty important. I ask you.....who doesn't want their top sash to open? This baffles me. It took me a couple of hours of work to finally get the sash to pull down (a pox on the owner that painted it shut). Sadly, this is a common situation, and they even make a special tool for it. I was a little surprised to see that the top edge is bare wood. I've had a vague suspicion that some of the sashes in my house are replacements. Either that or this sash has been painted shut longer than I suspected. Weston Stucco Toronto . It's open 365 days a year! When you think about stucco, there are many ways to categorize it: functionality, installation, durability, patching, etc. The reason for cement stucco is really how it looks on the outside of our structures. As a society, we start with function and move to esthetics. We started with packing mud over a straw to keep the weather out, and now we are using different sizes of aggregates, materials and pigments to make our buildings more beautiful.
Weston Stucco is introducing a brand new colour chart this year, and it coincides with their 19th anniversary. Their extensive and capable merchandising department has been scouring the globe to access the latest trends and colours. In years past, Weston Stucco has used its clientele of capable colour coordinators who worked for local building developers and home builders. This year, however, they took a more cosmopolitan approach and studied trends emerging from the largest fashion markets. It is essential to stay abreast of trends in design and colour. The colour chart, like paint fan decks, is used extensively in architectural offices and design centers to begin the process of choosing colours for our most popular buildings and homes. Here in the capital of “glitz and glamour,” it is not uncommon for Weston Stucco and Vero’s marketing departments to help choose colour for well-known stars and celebrities such as Jennifer Anniston, Dennis Rodman, and Sly Stallone, to name a few. We have discussed before how natural products make us feel more comfortable. Logically, materials and colours that are found in nature would be the colours we choose to lower stress in our living and work spaces. Over time, with trends in fashion and advertising and the need to change, colours do tend to ebb and flow in terms of popularity. However, earth tones tend to stay at the forefront as we see them in nature every day. Just think about the last time you went to a park or out in the forest. How many different greens did you see? There is an infinite variety of hues and textures to look at. This is why we can stay with natural colour tones and never run out of variation. As for man-made trends, we are always looking for things that excite and deliver“newness” to our homes, neighbourhoods, and workplaces. Through fashion, these are ever-evolving. Fashion is a significant contributor to interior and exterior colour design. Some colours may take on a more critical role in specific climate locations, such as reds are more popular in colder climates and blues are more popular in warmer climates. Overall, neutral tones can complement any design and, therefore, are used in any location. In the 1980s, pastels were very popular in stucco. The colour charts were full of light yellows, pinks, and beiges. If you look at those charts now, they are dated! But think about a picture of yourself from the 80s, see the mullet and clothes, it’s laughable! This is what makes it so much fun, though. In the late 1990s and early 2000s, it was all about “Tuscan” and “Mediterranean”. It was not uncommon to hear the owner ask that the house “look 200 years old “when it was completed. They did a lot with “distressed” wood timbers and exposed beams, ancient-looking balustrades, and a porte-cochere. Now the look is contemporary. Spaces are large and simple without clutter. Exteriors are going to have a clean monolithic appearance with natural cement colours. In commercial interior spaces, some have exposed HVAC systems and real or replicated poured-in-place walls. Weston Stucco has had a massive resurgence in an old product called Super Stucco Finish. This material was initially used in locker rooms, industrial kitchens and large areas that had moisture much of the time. This material was applied over a brown coat as an exterior smooth Santa Barbara Finish and then painted. Now calls come in from all over the world looking for a natural cement product for showers in high-end luxury lofts like those in downtown New York, Los Angeles, and other urban areas. Ten years ago, the market was flooded with authentic and knock-off “Venetian Plasters”. Now, the contemporary market is using lime and resin to achieve that natural “clean look”. Weston Stucco is an importer of real Dolomitic Lime from Trieste, Italy. When the demand for aged buildings lessened, it was challenging to make the design community aware that lime is ideally suited for contemporary designs. The resin plasters are beautiful, shiny, and can add flavour and excitement to walls and ceilings. The industrial look has become very popular, and many architectural firms have this lovely “minimalized” interior space.e Toronto Fashion Week is held each spring, showcasing its colours for the following year’s colour palette. This influences everything from clothing styles and colours to paint fan decks and building facades. Weston Stucco has always been the leader in choosing new and exciting colours on colour charts, and designers are used to working with a company that is as discriminating as they are. So here is to 50 years of service and thousands of colours in the Weston Stucco database! Now we have Vero Italian Finishes that are building a repertoire of great colours for lime and resin. Vero has even started carrying Modern Masters for metallics and pearlescent additives.

There are many sealers on the market. Most are to protect the surface from water or moisture intrusion. Some sealers are designed to enhance the beauty of the surface or add gloss or a “wet look”. Sealers can be categorized as surface or penetrating. Surface sealers are usually silicone-based and last from as little as a few months to a few years. The reason is that silicone is a larger molecule and, therefore, sits closer to the surface. Since UV light is what attacks these sealers, the larger molecule silicones will break down first. Penetrating sealers are usually silane and or siloxane-based. This is a smaller molecule and, therefore, penetrates further into the surface before forming the hydrophobic barrier. Silicones are usually less expensive than silanes, so how long you want the sealer to last is the important question. The substrate is the next most important variable. How porous is the material? This will determine how deep a penetrating sealer will go. This is a two-edged sword; the material will last longer as it penetrates deeper, but it won’t seal the surface from staining. The primary function of a good penetrating sealer is to keep moisture out of the wall cavity. This is where the water can do the most damage. It can find a way into our homes, damaging drywall and carpet, but what we don’t see is usually worse. Degradation of wood framing, damaging electrical outlets and shorts and the growth of moulds are just a few examples of damage water can do as it enters the wall space. We must be aware, however, that penetrants are just that; they will not protect the surface from staining unless applied in subsequent coats. The proper way to put on penetrating sealers is to make sure that new concrete, masonry or stucco is cured and “thirsty” enough to accept the chemical. Since the chemical is now carried by water, this is pretty easy to test. The literature usually says to wait the initial 28-day cure period before application. The problem with this is that your wall can get badly stained in 28 days. My advice is to gauge the weather against how dry or “thirsty” your substrate is and then make your own decision as to when to apply the sealer. These sealers need to form a barrier, so enough material must be applied to create this barrier. This usually means we put on a “flood coat” and then brush off any excess material. From a chemical engineering perspective, the exact proper way is to apply a very light “fog coat” of material to “open the capillaries” of the wall. Then come back immediately and flood the surface to ensure the wall accepts as much material as possible. Most often, people use a pump-up “bug sprayer” and fill the wall with the material until it runs, and then backroll or brush off the excess. There is a critical caveat here, though, when it is hot, dry, or windy, and when working on flat surfaces, it is critical to apply the right amount of sealer. If there is too much material and the substrate cannot accept the chemical, it will be deposited on the surface. This will result in a residual sticky material left on the surface to catch dirt, leaves, footprints, or other debris. So try to do the job in the morning before the sun is too hot, and don’t use these sealers when it is windy, because this will prevent an even application. If you find that there is residual material left on any surface, you can cut it off with a solvent. Paint thinner or any other solvent can be put on a rag and cut the material off the surface. Don’t worry, the rest of the material will still be on the wall as long as you don’t let the solvent penetrate. Just use it to wipe off the excess chemical so it doesn't drip off the rag. It will evaporate very quickly and be gone, leaving your sealer intact. Remember to cover all windows and frames as these penetrants can etch glass. Please read all the safety instructions before use. Think about the material you are putting the sealer on. Is it a flashed brick with very little suction? Then the material will go in very slowly or not at all. Very porous products, like a Concrete Masonry Unit (concrete block), are very porous and will, therefore, use a lot of products. Weston Stucco makes a penetrating sealer called Micro-Seal II that is less expensive than any other penetrating sealers I have found. It is a great product and is warranted for 10 years! The literature will show how much sealer will cover different materials. Logic dictates that the more “open” the surface, the more material will go in and the further it will go in. The less “open” the substrate, the less the material will go in and will, therefore, go further in terms of coverage. You can use these products on brick, block, stone, concrete, stucco or any other cementitious substrate. I have found over the years that silicones are used because people are unaware of silanes. Why would you use a sealer that will last 3 years at best when you can use penetrants lasting 10 years? The price difference is not that much. I guess if it is the model complex of homes or a case where a year of protection is fine, then the less expensive silicone will fill the bill. I talk mostly to homeowners who are doing their own homes and want maximum protection for the longest period. Go with a good penetrating sealer and take all the precautions talked about here, and you will protect your surfaces without having to reapply every few years. Homebuilders used to find buyers who wanted the new-car smell of a new home with community parks and the ability to customize features, like an in-law suite, home office, or granite countertops. Today’s homebuilder has more advantages over existing housing stock than ever before, as I learned from a seminar I attended at the Canadian Society of Building Designers.
We have reached the tipping point where existing homes cannot compete with a new home. Think of all these features possible with new homes that existing homes can’t touch: · No gas and electric bills (Zero Net Energy) · Luxurious comfort from even heat distribution, elimination of harmful chemicals · Proper site orientation and shading to allow sunlight in where and when it’s needed · Open floor plans · No moisture problems from a new, well-designed building envelope · Community amenities made famous by The Irvine Company, such as parks, pools, and new schools · Pleasing planned communities with open spaces, designed to encourage social interaction · Home automation for the technophile buyers Existing homes may have a few advantages of their own – locations closer to jobs and fire-sale prices for the moment. But as Huseyin Alanci demonstrated in his passionate blueprint for the building industry, the ownership cost of a new home, after taking into account reduced utility bills and maintenance expenses, is undoubtedly lower than that of even a short-sold existing home. Sam is ahead of the U.S. EPA’s energy efficiency program called Energy Star for Homes and has contributed to USGBC, NAHB, and DoE programs with energy efficiency goals. Sam made an impassioned case for the homebuilding industry to seize the moment, elevate their craft, and permanently leave existing housing stock in the dust. There is much work to be done. Many homebuilders are still focused mainly on getting low bids and trying to sell directly to these distressed existing homeowners. As a result, there is pressure on subcontractors not to innovate but to focus mainly on keeping costs low. And material manufacturers feel that pressure as tight margins, commoditization of our products, and more challenging times ahead. But there are promising signs if you look hard enough. Several major homebuilders in the Greater Toronto area (Mississauga, Woodbridge, ON) are using continuous insulation stucco systems in Toronto on all their projects, and highlighting that feature in selling their homes. Of course, these “one coat stucco” systems have been in use in other markets for decades, but Title 24 and the demand for “greener” homes have driven their adoption in Southern Toronto in recent years. Toronto’s Title 24 energy code ratchets up the energy efficiency mandate on homes in 2014, with additional code cycles set to take effect in 2017 and 2020. By 2020, Toronto’s Title 24 will likely mandate Zero Net Energy home performance. Forward-thinking homebuilders will get there sooner and establish their brands as synonymous with energy efficiency, much as Mercedes has with car safety. As stucco manufacturers and allied companies, the challenge for us is to provide products and technical assistance to encourage this metamorphosis of our industry. As the homebuilders go, so go our businesses. Suppose we can help builders seize this opportunity now, when we’re at the tipping point. In that case, we can strengthen our industry, de-commoditize our products and gain some competitive advantage for our own companies. Choosing Stucco Colors | Toronto
There is always quite a stir over colours in stucco in Toronto. The designers, architects and owners want the colours that will make the project sell more quickly, add appeal, match existing schemes and make an aesthetically beautiful project. The contractor warns that heavily pigmented colours are expensive, troublesome and susceptible to problems. What is the answer? It is, of course, complicated, and pros and cons must be weighed. Let’s start with the most asked questions about stucco and colour: 1. Pigments are expensive, and when you get over a Kilo, the price goes up. This is true. Typically, manufacturers allow one pound of pigment in a sack of stucco in Toronto with no extra charge. Blue and Green are the exceptions as they are more expensive colours. Pigment is by far the highest cost raw material in stucco in Toronto by weight. When custom homes want that rich earth tone with four pounds of colour, it can be as much as twenty dollars extra per sack. Remember, though, if we are talking about a high-end custom home, then the homeowner should get what they want for an exterior colour. A huge custom home might use 100 sacks of stucco, and even at $20, this is only $2000 more. 2. The contractor says he has a hard time making stucco in Toronto, even and consistent with heavily pigmented colours. This is also true. However, keep in mind what texture is wanted. A lace texture or sand finish is very unsightly with mottled colour. In this case, the wall would certainly have to be fogged to even out the colour. In smooth finish applications, colour mottling is typically required. With darker colours, we see movement and character in the stucco. It becomes a benefit and part of the artistic beauty of the finish. Toronto, ON - PP-5223 3. Are some colours so dark that a fog coat cannot be produced for that colour? This is a common assumption, and most stucco manufacturers have specified limits on making fog coat with over 4lbs of pigment. The reason is that fog coat comes in a 25lb bag. Suppose there are 5 lbs of colour in the bag, which constitutes 20% of the bag by weight. We cannot remove that much cement and other ingredients from the bag to accommodate this much colour. Similarly, we cannot produce heavily pigmented pre-mix stucco for the same reason. We never want to put so much colour in the bag that it threatens the integrity of the product. We should be able to produce a fogcoat that can even out colour variances using dark pigments. The solution then is to make a fog-coat in base and colour and let the contractor mix it in the field. 4. Are colours more “problematic” when they are dark? Yes, stucco is certainly not paint. It is not logical to expect stucco to react as paint does. Weather plays a huge part in how stucco looks, and the more pigment involved, the more the weather and other variables can affect colour. Efflorescence is more noticeable in darker colours. It is not because there is a higher presence of salts; it is that salts are white by nature and show much more on darker walls. 5. My contractor has asked me not to use the dark colour I want for my home. What should I do? It is your home, and as the owner or builder, you should have what you want. But… Go in with your eyes open! He doesn’t want to do it because he has experience that many things can go wrong, and he knows that he will be blamed for the problems. My advice is to: a. Always do a mock-up and agree on the colour before starting the job b. Discuss mottling, efflorescence, extra cost and find the tolerances and expectations of both parties and put it in writing! c. Discuss what to do in the event of freak storms, repairs resulting from damage by other trades and who will pay for these issues. d. Weigh the pros and cons very carefully when choosing colour. Remember, stucco is by nature a natural product. All the raw materials are from the earth, and it is almost always hand-applied. This is the beauty of the product. We don’t have to redo it every few years like paint. Stucco has an extremely long life cycle. So, like any natural product or handmade material, specific allowances must be made for the very nature of the product. Life is a give and take, so go for that dark colour on a smooth wall! Enjoy the beauty of the staining and mottling the same way you would admire your handmade antiques with all of their beautiful imperfections! Take so go for that dark colour on a smooth wall! Enjoy the beauty of the staining and mottling the same way you would admire your handmade antiques with all of their beautiful imperfections! Many people are confused about the difference between real cement-based stucco and synthetic stucco. In the 1970s, we started hearing about stucco that didn’t crack and had more colour consistency than the stucco we were using. Then the word EIFS (Exterior Insulation Finish System) was thrown around, and the confusion started.
EIFS is for energy efficiency using foam boards or other products to achieve better insulation value, and is a whole different discussion. Much can be learned online regarding EIFS Systems. One of the problems is that we have so many names for synthetic stucco, such as Acrylic Stucco, Synthetic Stucco, Plaster Finish, and manufacturer names such as MX Acrylic, Dryvit, Sto, Synergy, Thoro, etc. Here is the difference: Synthetic Stucco is made from acrylic resins and is very similar to paint. They have an aggregate added to replicate the look of stucco without some of the inherent problems of real cement stucco. Different sizes of sand are used to achieve different finishes, as traditional stucco uses various sizes of aggregates. Once on the wall, it would be difficult for anyone to tell the difference between Acrylic Stucco and a painted cement stucco wall. The key here is painted. It is pretty easy to tell the difference between real and synthetic, if not painted. Even though the products are supposed to be similar, when they are installed, they are worlds apart in physical makeup and functionality. Real Stucco uses natural materials and is cement and lime-based. Synthetic stucco is an acrylic resin-based product that uses no cement or lime. The similarity is the sand or aggregate used. The functional aspect is also essential. Synthetic stucco stops water from coming into the wall and is either characterized as waterproof or at least water-resistant. Cement Stucco typically dries hard enough to keep water out, but the idea is not necessarily to keep water out of the stucco. More importantly, it can penetrate the stucco and then naturally wick out and dry by being highly vapour permeable. Synthetic Stucco can retain moisture if it can find a way in. This is usually through the windows, doors, or roof lines. Because of water-related issues, the manufacturers have tried to use co-polymer resins that have more vapour permeability than earlier synthetic stuccoes. Cement Stucco is very rigid and is susceptible to cracking. This has been by far the number one problem associated with stucco. Many variables cause cracks, all related to movement, and can be read about in earlier Blogs or online. Stucco also tends to dry differentially depending on how long the moisture stays on the wall. Cement Stucco typically is darker if it dries slowly and lighter if it dries quickly. In hot, dry, or windy conditions, the entire building can be lighter in colour than intended; conversely, in cloudy, moist, or wet conditions, the whole building can be darker than intended. In addition, walls can dry differently just based on shading. The north side of the house can be drier than the south side. Even shading from the plank, trees, or other structures can reflect onto a wall and cause discoloration. Synthetic Stucco was introduced to solve these problems, and for the most part, it did. Since Synthetic Stucco is similar to paint, it dries more evenly. Because of the nature of the resin, it moves more than cement stucco and is less prone to cracking. Keep in mind, I never said “solve or eliminate” the problems. Problems and their manifestation are all a result of degrees - how much movement, how much water intrusion. The other question was, of course, cost. A Price was always the motivation for using traditional cement stucco. It is relatively inexpensive. Synthetic Stucco changed that and made the cost significantly higher. Still, when stacked up against other claddings, both these materials are very affordable. So let’s go through and recap these products: Synthetic Stucco Toronto 1. Made of Copolymer Resin 2. Uses sand or another aggregate to achieve the look of Cement Stucco 3. Resistant to water 4. Crack resistant 5. Colorfast 6. Comes wet in pails 7. Spread with an acrylic trowel 8. More appropriate for dark colours 9. Able to have smooth to weighty textures 10. More expensive than cement stucco 11. Can be used over a brown coat or in EIFS (Exterior Insulation Finish System) Traditional Cement Stucco Toronto 1. Made of Cement and Lime 2. Uses different sizes of sand to achieve different finishes 3. Highly vapour-permeable 4. Comes dry in bags 5. Spread with steel trowels and float 6. More of a “natural look” 7. Less expensive As you can see, there are more differences than first meets the eye when making a decision which product to use. Cost is a factor, and how the materials function and ultimately look are certainly things that need to be addressed. Do your research, look at the budget, and make the right decision based on your design needs and expectations of all involved. Stucco consists of four significant application steps. The first application is the moisture barrier/water management system. The moisture barrier prevents moisture intrusion into the substrate and framing of the wall. Then lath is applied after the moisture barrier and is composed of either woven wire or expanded metal.
Woven wire (chicken wire) is typically used on stucco applications under 5/8-inch thickness, and expanded metal is applied for heavier systems from 5/8” to 1”, as well as synthetic stone. The lath supports the base coat; base coat application typically ranges from 3/8 of an inch to 1 inch. Most of the stucco applications on Toronto’s newer homes are 3/8 to 1/2 inch thick and are called HCS or hard coat stucco. Structural systems 5/8” to 1 inch are not usually necessary in Toronto; the building code in Toronto requires shear standards to be built into the structure (carpentry). The last application is the finish coat; this is the application you see: colour and texture. The most popular finish materials used in Toronto are usually synthetic as opposed to Portland-cement-based finishes. Huseyin Alanci Weston Stucco Ltd. Toronto's Top Stucco Contractor. www.westonstucco.com A qualified stucco applicator should do repair and maintenance of stucco or EIFS (synthetic stucco). Often, piecemeal repairs can look worse than the original damage; a good example is woodpecker holes. Woodpecker damage wreaks havoc on Toronto real estate. Some products can be applied over stucco and EIFS to repair and prevent further damage caused by woodpeckers. Cracking can be successfully remedied with a fibreglass mesh overlay and refinishing of the affected wall plane. Areas being repaired should be refinished from a corner to a corner, completely covering the wall plane that is affected by the repair.
Stucco should not be painted! Painting stucco seals the system and prevents it from releasing small amounts of moisture, which can cause bubbling under the finish coat as moisture tries to escape. Painting also causes a maintenance issue. Suppose you paint it once; you must repaint it later. Also, paint fills in the texture of the stucco. After a few years, the stucco will appear like plastic, and its character will disappear. Let the stucco age; it will fade evenly through the years, giving it character. Stucco should be refinished every fifteen to twenty years; finishes eventually wear and lose their protective element. The recoat can be a perfect time to change the colour of your home. Sealant application around windows, doors and all penetrations must be maintained! Water movement through these areas causes roughly eighty-five percent of stucco failures. This problem can be easily remedied by using a qualified factory-trained applicator to seal around all stucco penetrations. I hope this brief overview helps you understand the maintenance issues of a stucco home. Huseyin Alanci Weston Stucco Ltd. Toronto's Top Stucco Contractor. www.westonstucco.com A perception often encountered in the maintenance industry is that stucco cannot be installed or repaired in the winter months. Nothing could be further from the truth. Several maintenance issues should be addressed in the winter months. One of these issues is sealant application around windows, doors and other penetrations. Sealing these areas will prevent additional heating costs and moisture intrusion issues.
Windows and doors are major culprits causing loss of heat, and loss of heat equals loss of money. Windows and doors inherently lose heat in the winter and reduce the effectiveness of air conditioning in the summer, because these wall penetrations do not have the insulating value of an exterior wall. This problem is compounded if sealant between penetrations and stucco has not been applied or if the sealant is old and delaminating. Proper sealants (urethane and specially formulated silicone sealants) should be applied. These specialized sealants are formulated to withstand ultraviolet exposure from the sun and moisture intrusion. UV exposure can reduce latex and most silicone to waste in a very short time. Notice I use the term sealant instead of caulk. Painters use caulk to fill gaps, mainly for aesthetic reasons. A sealant is a barrier against weather intrusion and should be applied at all penetrations in the stucco. There are plenty of temperature breaks in the winters of Toronto. Sealants can be applied in mild weather and will begin saving heat and money as soon as they are used. The coming spring will bring driving rain that will inevitably cause water intrusion, causing mould, mildew and structural damage. Sealant application is a vital but often underestimated solution to heat loss and moisture intrusion. Weston Stucco can resolve the problem of a lack of sealant or improperly installed sealants. We will apply sealant using the most up-to-date installation techniques and the best products available. |
