PAINTBOOSTER Water Repellent Additive contains a proprietary “Water-Beading Agent,” and a unique acrylic resin. It does not dilute or weaken the paint like other paint additives that have little or no acrylic resin. When mixed with a top-quality latex paint or stain, PAINTBOOSTER’s water beading protection lasts for years. As it repels water and reduces water absorption, OKON PAINTBOOSTER helps prevent premature paint failure, wood rot and mold growth.
