Foundation coatings must form a continuous, pinhole free film after cure, adhere strongly to concrete or masonry, and resist hydrostatic moisture exposure within the intended service level. They must tolerate alkaline substrates, minor movement, and soil contact when protected by drainage boards. Key requirements include adequate solids or residue to reach target dry film thickness, compatibility with primers on dusty concrete, and resistance to wash off before cure. Buyers should verify water resistance after cure, peel or pull off adhesion tests, and crack bridging capability if settlement or shrinkage is expected.
