GacoDeck TopCoat

Easy Waterproofing For Your Balcony & Rooftop Deck

GacoDeck TopCoat protects deck surfaces – including balconies, patios, roof decks, ramps and elevated walkways. Apply TopCoat over plywood, concrete, metal, fiberglass and previously coated deck systems.

GacoDeck TopCoat is a water-borne, single component elastomeric coating that incorporates ADA-compliant granules for added slip and wear resistance. The coating is designed to create a fully adhered, durable waterproof membrane that expands and contracts along with the substrate.

WARNING: DAP Dynaflex 230® referenced in the GacoDeck application video is no longer a compatible product with GacoDeck. GacoDeckFill is the only approved acrylic joint filler for the GacoDeck system.
