Use what the pros use – Extremely strong adhesive sealant retains strength above or below waterline.
Tough, flexible bonds – Stays flexible, retaining strong bonds even during vibration, structural movement, swelling, shrinking or shock.
Bonds permanently – Ideal for sealing, bonding and attaching on the interiors of boats or on exteriors where shielded from the sun.
Long lasting formula – Tough polyurethane polymer resists weathering and salt water.

Makes construction jobs move smoothly and quickly.
Superior adhesion. Stronger than standard putty tapes. Easily trimmed with blunt tool. Awled quickly and cleanly. Provides watertight seal. Easy application. Excellent adhesion to sidewalls. No discoloration..
To purchase a quantity of 2 (100ft) see ASIN: B072N1P4NG. To purchase a quantity of 8 (400ft) see ASIN: B01D98QHB0..
For best results, apply in dry conditions above 40°F (4°C)..
NOTE: MH-19 is a sealant and not a structural adhesive. Its tacky surface allows the tape to adhere to various substrates to obtain a good seal, but it’s not intended to be the sole structural component. Mechanical fasteners may be needed..
