Surface Preparation:

Remove all loose dirt and existing paint so the #4800 adheres directly to the concrete or block.  If the walls are mildewed, first use a wire brush and bleach to remove all traces of mildew.  Efflorescence, a formulation of crystalline deposits caused by free alkalies leached from mortar, grout, or adjacent concrete should be removed with a muratic acid solution.  Finish preparation by carefully rinsing the wall with water to remove all dirt or residue.  It is important to have a clean, dry surface before applying #4800 Waterproof Coating.

Precaution:

Temperature and humidity affect curing time.  Do not apply if surface is damp or the surface temperature is below 50 degrees or if the temperature will drop below freezing within 24 hours. Follow all installation and surface preparation instructions to assure proper adhesion.  Protect contents of the container from freezing.

Clean Up:

Brushes and equipment may be cleaned immediately after use with water.
