What This Skylight Sealer Is Designed For

• Sealing aging or leaking skylights
• Reinforcing skylight surfaces without blocking light
• Protecting skylights exposed to standing water and UV radiation
• Restoring waterproofing at skylight transitions and penetrations

This product is designed for applications where preserving light transmission is essential, but long-term waterproofing, flexibility, and durability are non-negotiable. Silicone Skylight Sealer also integrates seamlessly with Countryman Coatings’ complete silicone roof restoration system, allowing skylights to be fully protected as part of a continuous, watertight roof assembly.

Translucent Protection With Structural Strength

Silicone Skylight Sealer is formulated to remain translucent after cure, allowing light to pass through while forming a seamless, waterproof barrier.

In addition to sealing, the coating adds measurable reinforcement to skylight surfaces thanks to its high elongation and tensile strength. This allows the cured silicone membrane to flex and stretch as the building moves, without tearing, cracking, or losing adhesion.

• Maintains light transmission
• Resists ponding water and prolonged moisture exposure
• Withstands rain, snow, and weathering
• Flexes with roof and building movement

This combination of translucency and strength is what sets this product apart from traditional sealants and coatings.

Compatibility and System Integration

Because silicone adheres exceptionally well to clean, dry silicone, Silicone Skylight Sealer can be seamlessly integrated into broader roof restoration systems using other Countryman Coatings silicone products.

This makes it ideal for:

• Tying skylights into surrounding silicone-coated roof areas
• Detailing skylight curbs, seams, and transitions
• Creating a continuous, fully adhered silicone system

When used as part of a complete silicone roof coating system, Skylight Sealer helps eliminate weak points and maintain long-term watertight integrity.

Application

Silicone Skylight Sealer is designed for controlled application to ensure proper film build and long-term performance.

• Apply using a medium-nap roller or airless spray equipment
• Apply at a rate exceeding 3 gallons per 100 square feet in a single coat
• Apply over clean, dry surfaces only
• Achieves proper build without blistering or sacrificing adhesion when applied correctly

Always follow surface preparation and application guidance to ensure optimal results.

The Bottom Line

Countryman Coatings Silicone Skylight Sealer is a specialized, translucent, 100 percent silicone coating designed to seal, reinforce, and protect skylights while preserving natural light. When applied correctly, it delivers long-term waterproofing, flexibility, and structural support, and integrates seamlessly with other Countryman Coatings silicone roof systems.
