Bottom board underneath an RV or manufactured home takes a beating from road debris, moisture, and general wear, and once it's torn or punctured, water intrusion follows. AP Products' Scrim Shield tape creates a permanent, waterproof seal over damaged sections without needing to replace the whole board.
It's a 4-inch-wide, 180-foot roll of polyethylene tape with adhesive on one side, giving you enough material for a full-length repair run or several smaller patch jobs from one roll.
A practical fix for bottom board damage before it turns into a bigger moisture problem underneath the trailer.
