PRODUCT DETAILS
All surfaces should be cleaned before sealing for best penetration and performance. Remove all old coatings, dust, debris and loose material. Remove oil, grease, algae, grime, mill glaze and mildew stains with SEAL-ONCE® Multi-Surface Cleaner.
After cleaning, test absorbency of surface 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 SEAL-ONCE® Clear Waterproofer.
Retest surface when dry.
Then apply SEAL-ONCE® All Wood Brightener to brighten and neutralize wood after cleaning. Follow instructions before applying SEAL-ONCE® Clear Waterproofer.
