What can I do with GacoDeck Kit?

GacoDeck is a high-quality waterproof deck system that can be applied over plywood, concrete, metal, fiberglass or previously coated decks (metal and fiberglass surfaces require a primer). One GacoDeck Kit will cover 100 square feet.


The GacoDeck system provides total waterproofing for balconies and rooftop decks over occupied living spaces. GacoDeck is a top-quality acrylic polymer coating system that provides lasting surface protection and waterproofing, plus a skid-resistant surface that cleans up easily.

GacoDeck creates a fully adhered, durable waterproof membrane which expands and contracts along with the substrate.

GacoDeck is perfect in hot or cold climates, because this high-quality acrylic coating does not soften in the heat or become brittle from cold.

What's included?

With the GacoDeck Kit, there's no need to hunt for polyester tape, brushes or rollers. It's all neatly packaged inside. To make the application go smoothly, the GacoDeck Kit includes step-by-step instructions, and a DVD demonstration of a GacoDeck application from start to finish. After your project is completed, clean up is easy — GacoDeck cleans up with just soap and water.

Ramps, Stairs and More.

GacoDeck coating will also provide an attractive, skid-resistant surface on platforms such as decks, boat docks, and stair treads, or on wheel chair ramps and walkways. For these applications, GacoDeck functions as a durable, easy to clean surface. See instructions for details.

Many deck coatings contain high levels of harmful solvents that are as dangerous to the environment as they are to the applicator and others in the immediate area. The outcome is increased difficulty and an unpleasant home improvement project that can make the most confident "do-it-yourselfer" think twice. The finished product is a rushed and messy job with a less than desirable final result. Many of these products require the experience and expertise of a professional decking company along with the associated high costs. Not so with GacoDeck! GacoDeck is a user-friendly Acrylic Polymer Blend originally developed for and still used by professionals since 1988. In simpler terms, GacoDeck delivers all of the durability and toughness of a professionally installed waterproof deck coating without the harmful and unhealthy vapors. And, because GacoDeck is a water based acrylic, clean up is easy with just soap and water. The result is a durable, attractive and more rewarding home improvement project.
