Why Choose Elastomeric Wall Coatings for Exterior Walls
If your exterior walls suffer from peeling paint or penetrating damp, a flexible elastomeric coating offers better protection than standard masonry paint. Over time, exterior walls and render systems can deteriorate, making your home suffer from issues like cracking, staining, or fading, which affect both appearance and integrity. Unlike basic paint systems, it forms a breathable film that still blocks moisture from entering the substrate.
Ideal for areas with inclement weather, textured wall coatings are particularly useful on older properties where movement and cracking are common. They’re also suitable for homes exposed to wind-driven rain or frost. Promain offers a complete range of products built to withstand the toughest outdoor conditions.
Common Problems with Exterior Walls
Exterior walls are constantly exposed to the elements, making them vulnerable to a range of issues that can affect both their appearance and structural integrity. One of the most frequent problems is penetrating damp, where water ingress seeps through the wall, leading to internal damage and unsightly stains. Cracking is another common concern, often caused by heat loss, building settlement, or the natural expansion and contraction of materials. In areas with high humidity or inclement weather, mould and algae can quickly take hold, creating health risks and further degrading the wall’s surface. Damp proofing failures can exacerbate these issues, allowing water to penetrate deeper into the building and cause long-term harm. Regular application of high-quality exterior wall coatings is essential for protecting exterior walls from these threats, ensuring your property remains weather resistant and attractive for years to come.
The Science Behind Elastomeric Technology
Elastomeric coatings are made using advanced acrylic resins that let the material stretch and contract without damage. This flexibility means it can cover hairline cracks and protect against new ones forming.
The coating remains breathable, allowing moisture vapour to escape from inside the wall. This is important for damp proofing and helps prevent mould, algae, and rot from forming beneath the surface. Used correctly, it creates a seamless, long lasting barrier across large wall areas.
Exterior Wall Coatings: Protection That Lasts
These exterior coatings are built to handle whatever the weather throws at them - rain, frost, heat, and UV rays. They resist dirt, cracking, flaking, and discolouration, keeping the building looking attractive year round.
Applying a primer or fairing coat before the final elastomeric wall coating can further enhance durability and ensure a smooth, visually appealing surface.
Because the coating is applied in a thicker layer than normal paint, it offers improved coverage and reduces the need for frequent repairs. Textured coatings also help hide uneven patches and surface damage, creating a more uniform finish even on worn-out walls.
How Wall Coatings Exterior Shield Your Property
Exterior wall coatings don't just improve appearance - they protect buildings from structural damage caused by water ingress, surface movement, and heat loss. They seal off porous substrates, helping prevent damp and condensation build-up.
These coatings reduce the effects of sun exposure and resist wind-driven rain. Many options also reflect heat away from the surface, making homes more energy-efficient. Applied with brush, roller, or spray, the process creates a consistent barrier that's easy to maintain.
Preparation for Coating: Getting Your Walls Ready
Proper preparation is the foundation of a successful exterior wall coating application. Start by thoroughly cleaning the wall to remove dirt, grime, and any loose material that could prevent the coating from adhering. Address any cracks or damaged areas with appropriate repairs, and strip away old or flaking masonry paint if necessary. The substrate should be stable, dry, and free from contaminants to ensure a strong bond with the new coating. For best results, the surface should also be breathable and porous, which helps prevent water ingress and damp from becoming trapped beneath the coating. By investing time in careful preparation, homeowners can achieve a uniform finish and a durable, long lasting wall coating that will withstand the harshest weather conditions.
Outside Wall Coatings: Application Techniques
For best performance, the surface must be clean, dry, and free from previous loose paint or material. Cracks should be filled, and any render damage repaired. Using dust sheets during preparation helps contain dust and protect surrounding areas and properties. Depending on the condition of the wall, the coating can be applied using a brush, roller, or professional spray equipment. High-pressure spray equipment (up to 75psi) is often used to apply the coating efficiently and achieve a uniform, textured finish. Coatings can also be sprayed onto surfaces, allowing for even coverage and improved appearance.
The coating bonds tightly to surfaces like brick, render, concrete, or stone. Proper surface preparation is vital - it helps the coating adhere better and last longer. Once applied, it forms a waterproof, breathable layer that keeps out moisture and dirt while allowing trapped vapour to escape.
Wall Coating Exterior vs Regular Paint
Wall coating systems from Promain offer much more than decorative colour. They resist harsh weather, block moisture, and flex with the surface to prevent flaking. Regular paint tends to peel and crack over time, especially when applied to exposed areas.
Elastomeric coatings also bridge gaps and surface movement, making them ideal for older homes or areas with unstable render. While the upfront cost may be higher than standard paint, they reduce future repairs and repainting, saving homeowners both time and money.
Wall Coatings: Choosing the Right Type
Choosing the right material depends on the building, substrate, and level of exposure. Promain supplies a wide range of options suitable for homes and commercial properties, including breathable textured coatings, silicone-based systems, and acrylic resin products.
Some systems are better suited to highly porous surfaces like sand and lime render, while others are ideal for solid masonry. A textured wall coating may suit rough exterior walls, while smooth finishes might suit modern homes. Our team can help match you to the right option based on your surface and weather conditions.
