Kilz original aerosol primer blocks most stains including water, smoke, tannin, ink, pencil, felt marker, grease and seals pet and smoke odors. Use on interior surfaces including drywall, plaster, paneling, wallpaper, wood, masonry, brick, painted metal and properly prepared glossy surfaces. Ideal for spot priming and direct application to furniture, molding, baseboards, door jambs and frames and other projects where a "focused application" is desired instead of a large flat surface. Kilz original primer is not recommended on flooring unless used as a subcoat to new carpet or hard flooring.
