Bonstone Materials Touchstone Edge System – 3 Gallon Kit, 2 Gallons, 2-component Kit
Bonstone Materials Touchstone Edge System – 3 Gallon Kit, 2 Gallons, 2-component Kit
The Bonstone Materials Touchstone Edge System is a transparent flowing epoxy adhesive for countertop lamination, supplied as a three-gallon kit of two 1-gallon cans of Part A and one 1-gallon can of Part B and mixed 2:1 by volume.
Key Features
- Mix ratio is 2:1 by volume - two parts of Part A to one part of Part B.
- Three one-gallon cans arrive in the kit, but they are not interchangeable: two are Part A and one is Part B.
- Cure is 2 hours at 75F.
- Transparent, which is why it takes tint predictably for a color match.
- Flowing viscosity, intended for stone-to-stone lamination and edge build-up rather than vertical work.
- Also sold as separate Part A and Part B pails, so a shop can rebalance the 2:1 ratio without buying a whole kit.
Who Is This For?
Countertop shops building laminated edges and bullnoses, where a flowing epoxy wets out the full glue line and a two-hour cure lets a run of edges be clamped before the first is dressed. The three-gallon kit is a production pack rather than a repair pack.
What This Is Not For
Setting stone or tile onto wood, backerboard or metal is not this product's job - a flowing epoxy runs out of a bed joint. Use the Bonstone Materials Touchstone T-2000 Knife-Grade Epoxy Setting Adhesive for those substrates, or the Bonstone Materials Clear Gel Epoxy where a non-sag knife-grade consistency is needed on a vertical or overhead joint.
Frequently Asked Questions
What is the mix ratio?
The Touchstone Edge System mixes 2:1 by volume, two parts of Part A to one part of Part B.
Does the three-gallon kit contain three gallons of the same thing?
No. A Touchstone Edge System three-gallon kit is two 1-gallon cans of Part A and one 1-gallon can of Part B, which is the published 2:1 ratio.
How long does it take to cure?
The Touchstone Edge System cures in 2 hours at 75F.
Can it be tinted?
The Touchstone Edge System is transparent, so it accepts colorant for a color match rather than fighting a base color.
What other sizes does this kit come in?
Bonstone publishes the Touchstone Edge System as a 3 quart kit, a 3 gallon kit and a 15 gallon kit, each holding the same 2:1 split of Part A to Part B.
