Simple Three-Step Installation Process
- Clean the joist surface making sure it is dry and free of debris.
- Remove the butyl tape backing while applying directly to the surface. Run your hand over the tape and firmly press it on to the joists.
- After covering all horizontal and vertical surfaces, cut the tape to length with a utility knife or scissors.
HOW IT WORKS:
- Apply to horizontal and vertical surfaces including all joists, rim joists, bearers, steps, stair stringers, blocking, ledger board, and under joists hangers.
- Available in two widths 50 mm for joists and 100 mm for double bearers.
