Description
Bright white knife-grade polyester for Thassos marble and pure white stone. Tenax Thassos T is a knife-grade polyester adhesive formulated specifically for repairing, bonding, and filling Thassos marble and other bright white natural stones — where standard white or buff polyester reads as off-white or cream against the pure, bright white of Thassos. The Thassos T formula is calibrated to match the distinctive brightness of Thassos marble for invisible seams and repairs.
True knife-grade consistency holds on vertical surfaces and edges without sagging. Cures to a polishable, glossy finish. Interior use only; not suitable for temperatures below 32°F. 12-month shelf life.

When to Choose Thassos T
Use Thassos T when working with Thassos marble or other pure bright white natural stones where standard White or Optical White polyester reads as too warm or off-white against the stone. For standard white and light-toned stone, Tixo Xe Transparent is typically the better choice.

How to Use
