Underwater Magic Adhesive & Sealant White 290 mL Tube UWM-01
Underwater Magic Adhesive & Sealant White 290 mL Tube UWM-01
Most pool repairs start with draining the pool — this one does not. Underwater Magic is a professional one-component adhesive and sealant based on MS polymer that bonds and seals directly underwater, so loose tiles, leaking joints, and cracked shells can be repaired with the water in. It is 100% silicone-free and free of solvents and isocyanates, stays permanently elastic after curing, and resists chlorine, salt, and fresh water. Use it to re-attach and replace tiles (bonding and grouting in one step), renew pool-edge and expansion joints, seal around piping and fittings, and patch cracks in concrete, gunite, pebble, and fiberglass pools. The 290 mL (9.8 fl oz) cartridge fits a standard caulk gun, in the most common grout-line color: white.
🚩 PRO TIP: Preparation decides whether any underwater adhesive holds. Scrub the repair area with a Scotch-Brite pad to remove algae, grease, and loose material before applying UWM-01 — you are bonding to whatever is on the surface, so make sure it is the pool, not the slime.
