GA-20 Features & Technical Specifications

When choosing a high gloss concrete sealant, precision matters. GA-20 is engineered to penetrate deep into the concrete capillary structure without suffocating the slab:

Cure Schedule (at 70°F)

How to Apply GA-20 Solvent Based Sealer

1. Surface Preparation: Ensure the surface is completely clean, dry, and free of dust, oil, grease, and existing sealers. Allow new concrete to cure for at least 28 days. Apply only when the surface temperature is between 60°F and 90°F, relative humidity is below 85%, and the substrate is at least 5°F above the dew point.
2. Testing: Always apply a test area to confirm compatibility and final appearance.
3. Mixing: Stir GA-20 thoroughly before use. Do not thin.
4. Application: Apply using a high-quality woven shed-resistant roller (3/8" nap) or an acetone-resistant pump-up sprayer. Avoid pooling. Apply in two light, even coats rather than one heavy coat to prevent solvent entrapment (bubbling).
5. 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 (typically 3–5 hours).
6. Cleanup: Clean tools with Xylene or Xylol immediately after use.
