Helps Block


KILZ ODORLESS® is a fast drying primer, sealer and stainblocker. Its ultra low odor formula significantly reduces lingering odors, making it ideal to use in areas where higher odor levels are prohibitive. Its powerful stainblocking formula blocks most stains caused by water, smoke, tannin, ink, pencil, felt marker and grease; seals pet and smoke odors; and creates an excellent base coat for latex or oil-based paint. Use on interior surfaces including furniture, woodwork, drywall, plaster, paneling, wallpaper, masonry, brick, painted metal and properly prepared glossy surfaces.† KILZ ODORLESS is not recommended for mold or mildew-prone surfaces or on flooring.
