Countryman Coatings 100% Silicone Roof Coating for RVs & Flat Roofs — White 1 Gallon, Ponding-Water Resistant UV-Reflective

Countryman 100% Silicone Roof Coating (White, 1 gallon) is a high-solids, single-coat silicone formula designed to restore and waterproof RV and flat roofs while resisting ponding water and UV damage.

This premium silicone coating forms a durable, seamless membrane that sheds water and reflects sunlight. Because it cures to a pure silicone film, it stays flexible in changing temperatures and keeps out moisture where acrylics and solvent-based options often fail. It’s formulated for easy application and broad substrate compatibility—metal, EPDM, fiberglass, SPF, modified bitumen and many existing silicone surfaces—so many roof repair projects require no primer and fewer passes.

How does this coating perform on roofs with standing water?

Countryman’s 100% silicone formulation is engineered to tolerate ponding water without softening or breaking down, unlike many non-silicone coatings. The cured silicone creates a continuous, non-porous barrier that won’t absorb moisture and resists deterioration from prolonged exposure to pooled water.

• High-solids chemistry leaves a thicker protective film after curing
• Stable under ponding conditions—no rapid softening or washout
• Designed to maintain adhesion where water collects

Will I need a primer and how many coats are required?

For most properly prepared surfaces, this product bonds without a primer, saving prep time and cost. When applied at the recommended coverage rate, a single coat is often sufficient to restore and protect the roof, reducing labor and material use.

• No primer required for many substrates, including metal and EPDM
• Single-coat coverage when applied per instructions
• Additional priming or a second coat may be advised on porous or heavily weathered surfaces

How durable is the coating against weather and UV exposure?

The 100% silicone composition offers strong resistance to UV degradation and temperature cycling, helping the membrane remain flexible rather than brittle over time. Because it reflects sunlight in white finish, it also contributes to lower surface temperatures and reduced thermal stress on the roof assembly.

• UV-resistant silicone resists cracking and chalking
• Flexible through temperature swings to prevent splits
• White finish enhances solar reflectivity to lower heat gain

How do I apply and what surfaces are compatible?

Application is straightforward with brushes, rollers, or airless sprayers; surface preparation is the critical step—clean, dry, and free of loose material for best adhesion. Compatible substrates include metal, EPDM rubber, fiberglass, spray polyurethane foam (SPF), modified bitumen and previously coated silicone roofs.

• Apply with standard roof coating tools: roller, brush, or airless sprayer
• Ensure surfaces are clean, dry, and structurally sound before coating
• Compatible with many common roof materials; primer only when surface conditions require it

Who this product is for: Countryman 100% Silicone Roof Coating is ideal for RV owners, contractors and property managers who need a resilient, weatherproof membrane that minimizes recoat frequency and labor. It suits anyone restoring flat roofs, RV tops, or low-slope systems where ponding water, UV exposure, and long-term flexibility are primary concerns. Because it’s made in the USA and backed by local product support, it’s a practical choice for users who want professional-grade performance with clear resources for technical questions.
