Maxisil MaxiGrab Adhesive — One Hybrid-Polymer Adhesive That Grabs Everything (Even Underwater)

Every install has that one piece that won't stay put — a trim, a threshold, a fixture on a damp wall — and the usual construction adhesives either won't grip a wet surface or take forever to grab. MaxiGrab is built for exactly those problems: a hybrid-polymer adhesive with wet-grab strength so strong it bonds underwater.

It's a 1K hybrid polymer (STP, silane-modified) adhesive with no solvents, delivering superior grip, strength, and elasticity, plus a permanent bond that holds through moisture, movement, and load — the kind of high-stress installs that shrug off ordinary adhesive. It grabs almost any surface, damp or dry, and cures fast.

Because it bonds so widely, one tube of MaxiGrab replaces a shelf of specialty adhesives — in bathrooms, kitchens, and beyond. It comes in Original (white) and Crystal (clear) so you can match or hide the bond line. Pair it with the Maxisil sealant system — Wet Area, Natural Stone, and Pool — for adhesive and sealing from one brand.

Why Tile Pros Choose It

• Bonds underwater: Super wet-grab strength on damp or wet surfaces
• Hybrid polymer (STP): Superior grip, strength, and elasticity, no solvents
• Permanent bond: Withstands moisture, movement, and load
• Sticks to almost anything: Replaces multiple adhesives
• Fast curing: Grabs quickly and holds
• Two options: Original (white) and Crystal (clear)
• Doesn't care that your surface is wet: Which most adhesives very much do

Pro tip: For damp or wet bonds, clear loose debris first and press the piece firmly to spread the adhesive for maximum contact — the wet-grab is strong, but coverage still carries the load. Reach for Crystal (clear) whenever the bond line might show.
