Resist Top Coat

RESIST Top Coat Aggregate Sealer

RESIST Top Coat is a premium protective sealer formulated with 100% methyl and methacrylate polymers to provide superior protection and aesthetic enhancement for exposed aggregate surfaces. As the final sealing layer in the RESIST Sand Finish Overlay System, it penetrates and encapsulates aggregate to create a durable, long-lasting protective film that preserves the appearance and performance of the finished surface.

Designed for professional contractors, RESIST Top Coat enhances the natural colors and pigments of exposed aggregate, delivering a rich wet-look finish that adds depth, clarity, and visual appeal. Its clear, non-yellowing formula maintains long-term appearance even under prolonged UV exposure and harsh outdoor conditions.

The advanced formulation helps reduce aggregate pop-outs by penetrating around individual stones and filling gaps and voids within the surface. Once cured, it creates a protective barrier that resists water intrusion, chemical attack, abrasion, stains, deicing salts, efflorescence, and damage caused by freeze-thaw cycles.

Application Overview

RESIST Top Coat is designed to enhance and enrich surface color while providing durable protection. Apply using a low-pressure sprayer (30–40 PSI), roller, or long-nap applicator. Work the material evenly into the surface while avoiding puddling, runs, sags, or excessive buildup. Because the product dries quickly, apply in manageable sections and avoid back-rolling into areas that have already begun to dry.

Contractor Pro Tips

• Apply in small sections to maintain a consistent finish.
• Use low-pressure spray equipment for optimal coverage.
• Avoid over-application and surface buildup.
• Maintain a wet edge during application.
• Do not back-roll into partially dried areas to prevent lap marks and uneven appearance.
