Bonstone Duropoxi F Flexible Epoxy Adhesive – 1 Gallon Kit

Description

Bonstone Duropoxi F is a two-part, exterior-grade flexible epoxy adhesive built for tile and stone setting on uneven surfaces where a rigid bond would eventually crack. It carries the same strength profile as the original Duropoxi formula, with one key difference: it remains flexible after full cure instead of going rigid like most two-part epoxies. That flexibility is what lets it laminate thin stone or ceramic tile veneer to a substrate that moves slightly with temperature and moisture, without the bond line failing first.

Why Fabricators Choose This Flexible Epoxy Adhesive

Mix ratio is 1:1 by volume, and working time runs 2 to 4 hours before set, which gives crews room to position large-format tile or veneer without rushing. It cleans up with water and a Scotch-Brite pad while wet, so there is no solvent cleanup step to plan around. The cured bond can be tinted with Touchstone Liquid Tints when color-matching is part of the spec, and the formula is rated for exterior, vertical, and horizontal applications alike, which covers most of the situations where a rigid epoxy would otherwise be the default choice.

Where a Flexible Epoxy Adhesive Beats a Rigid One

Stone and tile installers reach for Duropoxi F on uneven substrates, thin veneer laminating, and any exterior application where seasonal expansion and contraction would stress a standard rigid epoxy at the bond line over time. A rigid adhesive on a substrate that flexes even slightly tends to crack at the interface first, long before the substrate itself fails, and this formula is built specifically to avoid that failure mode. It is packaged as a 1 gallon kit, one gallon each of Part A and Part B, sized for full-day production runs rather than small patch jobs.
