How To Use Flood Tape & Flood Paste

For complete instructions go to: flexsealproducts.com/flood

Read entire label for directions and warnings before use.

• Apply to the exterior of the structure.

• Make sure the area is clean, dry, and free of grease, oil, and dirt.

• Use only on on smooth, even, nonporous surfaces. Do not bend tape around corners or irregular shapes.

• Measure area being sealed, leave clear liner on Tape and cut to desired length using a razor or sharp tool.

• Peel a small portion of the liner and firmly press the sticky side to the surface.

• Slowly peel away the backing as you continue to press on the surface.

• Using your fingers, plastic squeegee, or roller, press firmly to remove any creases, folds or air pockets.

• Once applied, use our Flood Protection Paste, Liquid, or Spray around the edges of the Tape to help prevent seepage.

• Adhesive bond is strengthened by applying firm pressure and will strengthen over time.


Grab a small portion of material from an edge and pull away from the structure. Using a small pair of pliers may be necessary. If any residue is left on the surface, use a stiff nylon brush, paper towel or rag with denatured alcohol to clean the area.
