Step 1 Light Repairs: Raised nail heads and/or screws should be secured before applying Deck & Concrete Restore 10X. If the galvanized coating is removed, the product will need to be taken down to bare wood only over the nails and/or screws and a rust inhibitor should be sprayed on the nail heads and/or screws. Touch up work will need to be done over those affected areas using left over Deck & Concrete Restore 10X. Using a power sander on the deck should be done with care to ensure galvanized coating is not stripped off the nail heads and/or screws. Remove loose splinters and replace severely damaged or rotting boards. Fill larger cracks using RESTORE CRACK FILLER or similar acrylic, non-silicone filler. Allow to dry.
Step 2 Clean: Clean the surface using a brush and the Restore Deck & Concrete Cleaner. The surface must be completely clean and free of dirt, grease, mildew and organic growth to ensure product bonding and adhesion. For best results use a pressure washer to remove embedded dirt and grime. (Use at a low setting 500-1200 PSI. Do not use high pressure as it may harm the wood.) For grease and oil spots use tri-sodium phosphate (TSP) according to manufacturer’s directions to remove stains. For mildew and other organic growth use a diluted solution of household bleach (3 parts water to 1 part bleach) applied to the surface before cleaning. Loose paint needs to be scraped or sanded (use 50 grit sand paper).
Step 3 TEST SURFACE BEFORE APPLICATION:
After cleaning the surface you MUST conduct a splash test to ensure proper adhesion. Previously applied sealers may be present on the deck and are not always visible. ALL EXISTING SEALERS, PAINTS, STAINS, WATER REPELLENTS OR OTHER FINISHES MUST BE REMOVED in order for Restore 10X to adhere properly. To check for the presence of these, conduct a splash test by sprinkling water on multiple areas of the surface. Check at least 4 areas, or more for larger areas. Be sure to check both high traffic areas such as walkways and non-traffic areas. If the water absorbs rapidly into the surface, the surface is ready to be coated. If the water beads, puddles or is not absorbed, the surface is sealed and not ready to coat. If the surface is sealed, remove the sealer/coating with a deck stripper or sand paper (use 50 grit). Clean again with a brush and Restore Deck & Concrete Cleaner and conduct the splash test again. Continue this process until the water is absorbed by the wood in all test areas. Let the surface dry completely before application. Failure to follow this process will result in poor adhesion and possible coating failure.
