To check for trapped moisture, tape a 12” x 12” piece of 3 mil plastic or aluminum foil tightly to the surface on all four edges. Remove it after 24 hours. If the surface side of the plastic or foil is damp, allow additional drying and repeat the test.
If you see white, powdery, crystal-like deposits on the surface, they are naturally occurring, water-soluble salt compounds in the masonry, pushed out by water intrusion. When the water evaporates, the salt residue remains. This effect is called efflorescence and, because it prevents DRYLOK® WetLook Clear High Gloss Penetrating Sealer from properly bonding to the surface, it must be removed. Treat it with DRYLOK® Etch** (liquid or powder formula) or muriatic acid according to the manufacturer’s directions, rinse and allow to dry.
DRYLOK® Etch will also properly prepare the concrete’s profile to accept the coating. Properly prepared concrete should look and feel like medium grit sandpaper. If the concrete remains smooth, repeat the etching procedure. You can test the concrete porosity by sprinkling a few drops of water onto the surface in several areas. If the water is readily absorbed, you are ready to apply the coating. If it beads or sits on the surface, additional cleaning and etching is needed. Rinse it thoroughly with clean water and allow it to dry for 24 hours.
Patch all holes and cracks with a suitable cement-based patching compound. Be sure to smooth the patch evenly. Allow the patched area to dry thoroughly.
