    Description Masonry Primer is ideal for use on interior and exterior bare masonry, cement, or concrete as a bonding surface for paint and adds an extra layer of protection. Priming is highly recommended, especially if the surface is not waterproof, or is made of porous materials. Not suitable for use with plaster. Before applying the masonry primer make sure the surface being coated is in sound condition. Masonry primer will not remedy any structural or surface issues.
    Preparation Surfaces should be clean, dry, sound, and free from dirt, dust, grease, and loose or flaking material. Clean stubborn areas with mild detergent. Rinse and dry thoroughly before priming. Soft or crumbly substrates should be pre-treated.
    Application and Clean Up Under most conditions thinning is not necessary. Stir gently before and during use. Generally requires only one coat. Normally dries to the touch in four hours. Allow twenty-four hours before sanding or painting. Can be applied using a good quality synthetic brush; or rolled using a shed resistant 1/4"-3/8" roller cover, or sprayed using an airless sprayer with 0.015” to 0.017” tip at 1600 to 1800 psi. Avoid applying below 50°F (10°C).
