Crown STRP MAX Paint Stripper Gel is safer than paint strippers using Methylene Chloride or NMP and works as effectively as paint removers using these harmful chemicals. Crown STRP MAX Paint Stripper Gel is a fast-acting paint stripper that effectively removes paint, enamel, lacquer, varnish, polyurethane, and epoxy from wood, metal, masonry, and marine surfaces in 30 minutes. One quart size covers up to 25 square feet, and half-gallon size covers 50 square feet. Gel formulation clings to vertical surfaces.
