Surface Prep Guide
Proper surface preparation with Flood® premium prep products is a critical step, whether refreshing an existing finish or prior to applying a new Flood wood finish. Removing dirt, grime, contaminants or previously coated wood deck, siding or wood fence stains and sealers will ensure a long-lasting finish for your wood surfaces.
