Description
The H2O putty board is the flat work surface that pairs with the Chem-Set H2O underwater repair system. It measures 12 by 12 inches, which gives you room to dispense, fold, and knead the two part H2O putty until the resin and hardener blend to a uniform color before you press it into a wet repair. A clean, rigid mixing surface matters because an incomplete blend leaves soft spots that never fully cure underwater.
Where the H2O putty board helps
Pool and spa crews, fountain and pond builders, and tank or sump repair teams all hand mix two part putty on the board before pressing it into a damp or submerged surface. Mixing on the board instead of in a gloved palm keeps hardener off skin, speeds a full blend, and gives a stable surface to work fast while the putty is still pliable.
- Pool and spa shell repairs below the waterline
- Fountain, pond, and water feature patching
- Tank, sump, and wet pit sealing
- Any underwater or damp surface where two part putty is hand mixed
How to use the H2O putty board
Cut equal lengths of resin and hardener onto the board, then fold and press them together with a spreader or gloved hand until the color is uniform with no streaks. Work the mixed putty quickly, since H2O begins to cure while wet. Wipe the board clean once the putty firms up so the surface is ready for the next batch, and keep a spare on hand for back to back repairs.
