Begin by cleaning the wall surface to remove any dust, dirt, or old paint. Cracks and imperfections should be repaired to ensure a smooth application. Applying a bonding agent can also enhance adhesion and durability.Applying the RenderStart by mixing your render according to manufacturer instructions. Use a trowel to apply the first coat evenly, usually about 10-15 mm thick. Allow it to set before applying a second coat, which can be finished with a sponge or float to achieve the desired texture.Final Touches and MaintenanceOnce the render has cured, you can paint it with a weather-resistant exterior paint for added protection and to achieve your desired color. Regular maintenance, including washing and inspecting for cracks, will help preserve the integrity of your render for years to come.FAQWhat is the best type of render for my climate?
