Flex-Prime Select Interior/Exterior Flexible Masonry Primer

FLEX-PRIME ® Select is an interior and exterior latex masonry primer that provides very good resistance to alkali and efflorescence. It is designed to bridge hairline cracks in masonry surfaces, resulting in a seal that is flexible and tolerant of movement in the substrate. FLEX-PRIME ® Select can be used on properly cured tilt-up concrete, poured-in-place concrete, stucco and block.
