PREPARATION
|
| • |
All surfaces should be cleaned before sealing for best penetration and performance of a coating. Clean all dust, debris and loose material. Remove oil, grease, mildew or mold with appropriate cleaners.
|
| • |
After cleaning, test absorbency by sprinkling a few drops of water on the surface. If the water does not readily penetrate the surface, stripping will be necessary to remove old coatings prior to applying product. (Sanding or removal of paint containing lead may be hazardous. Call 1-800-424-LEAD for details.)
