INSL-X Fire Retardant Paint is a high-quality latex decorative, intumescent, fire-retardant coating for interior ceilings, walls, and trim. This product provides a high-hiding flat finish that retards flame spread by reacting to heat and forming a thick cellular char blanket (intumescence). By reducing excessive heat penetration, this product retards flame spread and minimizes smoke generation. It is suitable for primed or previously painted wood, drywall, cellulose tile, cured plaster, masonry, and metal. It applies like conventional latex paint, is low in VOCs, and washes without spotting. This product may also be top-coated with conventional acrylic paint without affecting the flame spread rating.
