Kilz is a specialty paint brand with its roots in a 1954 paint dealership established by Melvin Caldwell. In 1974, under the company name Masterchem, Caldwell introduced the first Kilz primer product at a national trade show. Kilz is a leading provider of primers, paints and painting accessories.
The Kilz brand targets do-it-yourself homeowners who want a quality paint product at an affordable price. Primers are used to prepare for painting on siding, interior and exterior walls, and decks. Kilz also has ceiling paint products designed to repel stains. The brand also includes a spray to touch up existing stains on ceilings.
