Stone Coat Countertops Epoxy Undercoat Epoxy Paint Epoxy Coating, 32 fl oz

Applying Stone Coat Countertops Epoxy Undercoat is a fundamental step for flawless, long-lasting DIY epoxy countertops, tabletops, bar tops, and more. Designed specifically for use with epoxy, our undercoat is crucial must-have for ensuring a strong bond, eliminating issues like peeling or yellowing that can compromise the final look of your project. Unlike standard latex primers, our ammonia-free formula prevents off-gassing, helping to avoid any chemical reactions that cause discoloration. Plus, it provides a high-bond base layer, bringing enhanced performance and durability to every project, especially on porous surfaces like MDF.

Key Features:

• High-adhesion undercoat formulated for DIY epoxy countertops.
• Ammonia-free to prevent off-gassing, discoloration, and yellowing.
• Low odor and quick-drying for hassle-free indoor application.
• Designed for multiple surfaces, from MDF to primed countertops.

Application:

• Lightly sand new MDF or surfaces treated with Bonding Primer & Sealer using 220-grit sandpaper, remove dust, and clean with 91% isopropyl alcohol.
• Stir the Epoxy Undercoat thoroughly. Apply a thin, even coat with a 1/4 Inch Nap Microfiber Roller and use a 2 Inch Chop Brush for tight corners. Let dry for 1 hour, then lightly sand with 220-grit.
• Apply another thin coat, let it dry for 2 hours, then sand again with 220-grit.
• Allow 4 hours of drying after the second coat, prior to epoxy application.
• Clean spills and tools immediately with warm, soapy water.

PRO TIP!

Always start with two thin coats of our Bonding Primer & Sealer on old countertop surfaces before applying our Epoxy Undercoat. This will create a reliable foundation you can trust!
