Eco-friendly zero VOC crack and knot wood filler

Gulf Synthetics PermaFill (Perma Caulk) is an environmentally safe way to prepare any cracked or knotty wood deck, dock or fence. It leaves a hard smooth permanent surface. Apply it after priming surface with PermaBond.

NOTE: PermaFill is designed to work with PermaBond, please use both in conjunction to achieve optimal results.

Each gallon container includes two parts: a dry powder and a polymer resin which are mixed together in the bucket to form a peanut butter consistency. It is then spread with a putty knife into large cracks or knots, permanently sealing them.

Unlike latex caulking and other fillers which shrink over time, PermaFill expandable wood filler will never shrink. Because of its expansive properties, once it fills a void, it locks into the distressed wood and stays in place for years. It's the best way to prepare your old wooden deck or dock.

Each gallon container contains enough material to cover an average size deck of 180 square feet depending upon the condition of the wood and depth of the cracks. Cleans up with soap and water.
