GA-20 is a single-component, solvent-based acrylic concrete sealer formulated with 20% solids for superior surface protection and enhancement. It delivers a durable, breathable film that resists water intrusion while allowing moisture vapour to escape — perfect for a wide range of outdoor concrete applications. GA-20 enhances the colour of concrete with a rich, wet-look finish while offering outstanding gloss and fast drying times.
Whether you're sealing stamped concrete, overlays, broom-finished concrete, or masonry, GA-20 provides long-lasting beauty and protection. With a coverage rate of 250–530 square feet per gallon, it’s ideal for both residential and commercial exterior surfaces.

How to Apply GA-20
Surface Preparation: Ensure surface is clean, dry, and free of dust, oil, grease, and existing sealers. Allow new concrete to cure for at least 30 days. Substrate must be at least 5°F above the dew point.
Testing: Always apply a test area to confirm compatibility and appearance.
Mixing: Stir GA-20 thoroughly before use. Do not thin.
Application: Apply using a high-quality roller (3/8" nap) or solvent based sealer sprayer. Avoid pooling.
Apply in two light coats rather than one heavy coat. Drying & Recoat: Allow the first coat to dry according to the cure schedule above. A second coat can be applied once the surface is tack-free and shows no solvent retention.
