Description
Professional-grade epoxy for stone, tile, and countertop installation—even on uneven surfaces.
The Bonstone T-2000 is a super-strength, knife-grade epoxy adhesive engineered for the demanding needs of tile setters, fabricators, and installers. This 3:1 mix, smooth trowelable formula is designed to bond stone, tile, or countertops to difficult or irregular substrates like metal, wood, or backerboard—making it an essential solution when dealing with uneven surfaces.
Ideal for interior and exterior jobs, including vertical and overhead installations, T-2000 creates a thick epoxy bed that allows for adjustment during placement. It’s perfect for projects where both precision and reliability are critical—such as pool copings, elevator walls, or tiling over stainless steel.
