THE TIME PUT INTO PREPARATION WILL GREATLY BENEFIT
THE LONGEVITY OF THE COATING
For best results clean all timber prior to application of finishes to prevent early adhesion failure and drying issues due to contamination from tannins and extractives. All external timbers under 12 months old require will require preparation with SAP STRIP. Old, weathered grey timbers and dirty timber require cleaning with DEX PREP.
TESTING YOUR TIMBER
When using transparent coatings, wet the timber first. If the timber appears black, apply more DEX PREP to clean the deck and eliminate the remaining grey discolouration. Failure to remove all tannins and extractives off a decks surface will result in the surface under the coating appearing black, and will be visible on the timber surface under the coating.
