BOLDBase
BOLDBase is a water-based, 100% acrylic primer that is designed specifically for use on interior and exterior concrete surfaces, masonry, and brick. BOLDBase is extremely economical, easy to use, dries quickly, and remains flexible for longer periods of time. BOLDBase resists cracking, peeling and blistering, and offers easy clean up with soap and water. BOLDBase is formulated to penetrate the pores in the concrete to slow the transmission of water and to form a highly alkali resistant film, which will protect the finish coats against lime burn, discoloration and efflorescence.
