If shorter finishing times are required on new masonry, use Kilz Total One. Kilz Exterior can be used as a tannin sealer and undercoater on all types of wood. Because of the variance in wood substrates, even multiple coats may not stop tannin or rosin stains on all wood surfaces and knots. Kilz Exterior may be tinted with up to 2 ounces of universal colorant per gallon. Tinting to a lighter shade than the topcoat is recommended.
Coverage varies with porosity.
Kilz Exterior will dry to touch in 30 minutes and can be recoated in one hour. Allow two hours drying time if sanding is required before recoat. Application in lower temperatures, in high humidity or with poor ventilation can significantly increase dry and recoat times. Some stains may not be totally sealed under these conditions. Do not thin Kilz Exterior.
