  1. Protective clothing is recommended prior to starting any projects.
  2. Make sure the surface is clean, dry and free of grease, oil and dirt.

  5. The styrofoam piece is then glued to the damaged area using a two-part adhesive.
  6. The Seal Patch laminate is applied on top of the styrofoam wedge and surrounding area.
  7. Additional reinforcement tape is applied on top of the Seal Patch laminate.
  8. You can either brush, roll, dip or pour the liquid Seal Patch directly onto the surface of the reinforcement tape.

Tips for Brushing/Rolling Applications

  3. Always brush or roll over a larger area than just where the leak occurred.
