Infiniti’s 100% Acrylic Alkali Resistant Masonry Primer is a 100% acrylic primer specially formulated to resist “alkali burn” commonly associated with new cementitious substrates. Its special formulation provides excellent coverage, adhesion, low odor, and may be applied to surfaces with a PH level as high as 11. It dries fast, is mildew resistant, is non-yellowing, and has excellent priming and sealing properties. May be top-coated with both water and alkyd/oil-based finish coatings.
