KILZ HIGH BUILD® is a unique formulation that can be applied more thickly than most primers. KILZ HIGH BUILD creates a finish equivalent to a fully prepared skim coat (Level 5 finish) when sprayed thus saving time and money. As an added benefit, KILZ HIGH BUILD utilizes the superior stainblocking technology behind KILZ® PREMIUM. It effectively blocks interior stains, hides bold colors and has a mildew-resistant finish. It can be used on all interior ceilings and walls including paperless drywall, damaged or textured surfaces. It offers excellent enamel holdout, dries quickly (1 hour to recoat) and is easy to clean.
