Undoubtedly, as the weather turns wetter and colder, we look for additional weather protection for our homes. Rain, wind, ice, and a temperature drop may all impact the exterior of a property, both aesthetically and in more significant ways, if adequate protection is not provided. Weakening walls or roofs can let in rain and dampness, weakening the structure and making your home more uncomfortable if it’s cold and draughty. Rather than investing in pricey roof replacement or spending a fortune on heating bills, consider external wall coating to help maintain your property’s beauty and energy efficiency. Continue reading to learn more about it, how it works, and the benefits it could provide for your family.
What is exterior wall coating?
Exterior wall coating is a specialized waterproof coating meant to prevent moisture from infiltrating the bricks that make up the outer walls, providing additional protection from the weather to both the exterior and interior. Properla, a hydrophobic coating that repels water, is one of the most popular options for providing maximum protection. External wall coatings can be clear and suited for use on brick, sandstone, concrete, and stone or a two-coat colored facade for use on mineral substrates that require a colored outside wall coating. Exterior wall coatings are self-cleaning and very hydrophobic, but they are still breathable.
Consider weatherproof roof coating, a comparable substance developed to preserve tiles from prolonged exposure to cold, sunlight, and moisture. The coating employed is a one-of-a-kind, microporous, water-based membrane that is both wind and water-tight, providing excellent protection from the elements.
How does it work?
Exterior wall coatings help to insulate buildings by minimizing the amount of water absorbed by the bricks or other mineral elements. The coatings provide a very hydrophobic surface, which basically means they are incredibly difficult to get wet!
A substance is classified as extremely hydrophobic if it causes water to form droplets or ‘beads’ – the surface repels the water, which means it sticks to itself and runs off the surface, making it very difficult to absorb moisture. When the contact angle of water hitting a substance surpasses 150 degrees, droplets bounce back like an elastic ball. This has also been dubbed “the lotus effect,” after lotus flower leaves, which are also exceedingly super hydrophobic.
Each job is unique, but a quality wall-coating business should follow the process outlined below while preparing to coat your walls. First, all external building repairs will be completed, including crack repair, re-rendering, and restoring loose bricks, to create a gorgeous smooth surface ready for coating. If your house is previously painted, the old, flaky paint is normally removed before repairs are made, even if the covering being applied is clear. Some businesses will also pressure clean your walls to ensure that the surface is clean and fresh. The coatings are then applied in one or two coats by an experienced applicator using professional spray equipment to achieve an even covering. Depending on the climate, the coating will dry in 6-8 hours and require a second coat if necessary.
The process for preparing a roof for coating is fairly similar; the roof will also be pressure washed to remove any lichen, moss, dirt, or other debris from the guttering, such as leaves and sticks. This will be packed and removed so the team can apply the coating to a clean surface. Any professional agency, like the walls, should have a restoration surface, including fixing or replacing any damaged tiles and any loose or cracked mortar. In some situations, a fungicidal treatment is done before the roof coating to kill spores and prevent algae or other growth on your roof. Finally, the roof coating is done using specialized airless spraying equipment to guarantee that all tiles are covered.
The Advantages of wall coatings
As you will see in the following list, there are a lot of reasons why you should put money into protective wall coatings or roof sealant.
Wall coverings are designed to survive even the toughest weather conditions and may protect your property from rain, wind, frost, and snow – ideal for individuals who live in the north of England or Scotland, where the weather can be brutal during the winter. As previously stated, the application process also includes making any required repairs, sealing any weak spots in your walls, and ensuring your home is protected from the elements for years to come. Most coatings can penetrate up to 17mm into the brick or wall material, keeping dampness out on the surface while also preventing penetrative dampness from seeping into the walls.
According to tests, a damp content of just 5% in a plain brick wall can reduce insulation performance by up to 50%, so keeping your walls dry can make all the difference in how much heat stays inside your home. A damp wall acts as a “bridge,” allowing heat to transfer from the inside out twice as quickly. However, some leading wall coating products can reduce water absorption by more than 95%, resulting in less heat loss.
Even if you select a clear option, external wall coatings can completely transform the exterior appearance of your home. Because of the pre-treatment, your brickwork will be cleaned and repaired, and some wall coatings are available in a variety of colors to complement your existing decor. The super hydrophobic material repels water and dirt, making the walls self-cleaning and UV-resistant. This ensures that the building’s facade will remain clean and age more slowly.
This saves money
As previously stated, the insulation benefits of wall or roof coating can result in a reduction in heating bills – if less heat escapes, there is no need to keep the central heating on for as long or as high. Waterproof roof coating is also an excellent preventative measure; it can extend the lifespan of your roof by years and represents excellent value for money when compared to the costly task of retiling your roof.
Improves the value of your home
Even if you don’t plan on selling your home anytime soon, the ten-year guarantee on wall and roof coatings can add value if you decide to sell in a few years. Waterproof roof coating extends the life of your tiles while also ensuring quality for increased curb appeal, whereas exterior wall coating can make your property look brand new. Potential buyers are drawn to exterior coating because of the added protection and security it provides and the money they will save on heating bills.
Exterior wall coatings, as previously stated, prevent penetrative dampness while still allowing the walls to breathe. This means that air and moisture can still escape and will not become trapped, allowing condensation or mildew to build up. This ingenious technology keeps your home warm and dry without making it stuffy. It also aids in temperature regulation, allowing you to stay warm in the winter while remaining cool in the summer.
Mildew and other pollutants resistance
Moss, lichen, and algae find growing on your property’s walls or roof difficult due to the superhydrophobic surface. This keeps the building looking presentable and appealing while also lowering the risk of structural damage or dampness caused by inclement weather.
With the correct coating material and process, you can expect to avoid the potential of dampness and other inside concerns caused by external sources. All Weather wall coating is a dependable option for homeowners who live in locations with significant rainfall and snow, and it provides long-lasting benefits for your prized house.
