CP-500 PREMIUM is a spec grade polysiloxane water repellent that protects masonry and other building materials against damage due to penetration by water and waterborne chemicals. CP-500 PREMIUM is not a surface coating. It penetrates up to ¼ inch or ore into treated surfaces and bonds with the substrate to provide long lasting, protection, even at hairline cracks.
CP-500 Premium can be used on most vertical or horizontal, exterior, above-grade surfaces. Coverage rates vary from 50-250 sq. ft. per gallon, depending on surface porosity and texture.
