Bonstone Materials Touchstone T-2000 Knife-Grade Epoxy Setting Adhesive – Gallon Kit
The Bonstone Materials Touchstone T-2000 Knife-Grade Epoxy Setting Adhesive is a two-component setting adhesive sold as a Gallon Kit and mixed 3:1, used to bond stone and tile to substrates that resist ordinary thinset.
Key Features
- Mix ratio is 3:1 - the only 3:1 adhesive in the Bonstone range, which is why the ratio has to be read off the label rather than assumed.
- Sold as a Gallon Kit, meaning a two-component kit ordered as a single unit; Bonstone does not publish the Part A and Part B container split.
- Cure is greater than 2 hours at 75F.
- Knife-grade and trowelable, so it builds a thick bed that lets tile, stone or a countertop be adjusted on an uneven surface.
- Bonds stone and tile to wood, backerboard, metal, concrete and plastic, including stainless steel and aluminum.
- Used interior and exterior, on vertical and overhead work - pool copings, elevator walls, outdoor fireplaces.
Who Is This For?
Installers and masons setting stone or tile onto difficult substrates rather than fabricating countertops: tiling over stainless steel, bedding coping on a pool edge, setting stone on an exterior fireplace, or bringing an uneven wall into plane with a thick epoxy bed.
What This Is Not For
This is a setting adhesive, not a seaming or lamination epoxy, and it is not clear - it will not give an invisible glue line on a countertop seam. Use the Bonstone Materials Clear Gel Epoxy for knife-grade seam and chip work, or the Bonstone Touchstone Glacier Gallon Kit where a clear, fast-setting seam adhesive is what the job needs.
