Multi-Strip Remover is a professional-strength paint and varnish remover. It begins working in just 30 minutes and clings to vertical surfaces. The odor-free formula strips up to 15 layers of latex and oil-based paints and varnishes, lacquers and urethanes. It is environmentally friendly, nonflammable and cleans easily with water.
