Installing acrylic roof coating according to the manufacturer's specifications starts with thorough surface preparation. Begin by cleaning the roof surface to remove dirt, debris, and any loose materials, using a broom or power washer, but avoid saturating the roof. Check for any damage such as cracks, blisters, or loose flashing, and make any necessary repairs before proceeding. The surface must be completely dry to ensure proper adhesion. Often, manufacturers recommend applying a primer specifically designed for the acrylic coating to improve bonding. Allow the primer to dry fully according to the product instructions before applying the coating. Use a roller or sprayer to apply the acrylic coating evenly, maintaining the thickness recommended by the manufacturer—usually around 20 to 30 mils wet thickness, which might require multiple coats. Avoid applying in direct sunlight or when rain is expected within 24 hours, as this can affect curing and performance.
A safe DIY check is to review the weather forecast and ensure conditions are dry and mild; acrylic coatings generally cure best between 50°F and 85°F. Inspect the coating after drying for uniform coverage without thin spots or pooling. It’s important to measure the thickness with a wet mil gauge if available, as too thin or too thick applications can compromise protection and warranty. If you’re unsure about the surface condition, adhesion, or proper thickness, it’s wise to contact a professional roofer experienced with acrylic coatings. When reaching out to a contractor, ask, “How do you ensure the coating meets the manufacturer’s thickness requirement?” and “Can you provide documentation or photos during each application step to confirm warranty compliance?” These questions help ensure the job is done correctly and protects your roof investment.
