TEC Power Grout maximizes performance while providing one of the best ease-of-use grouting installation solutions. Its revolutionary scientific formulation is highly stain resistant and provides strong, color consistent joints by resisting efflorescence, fading, cracking and shrinking. Due to the high performance raw materials present in Power Grout, the cost per bag is slightly higher than regular grout but over the lifetime of your tile - you will save $$$ by not having to re-seal and re-grout your tile installation in order to maintain that just-installed fantastic finish.

TEC Power Grout is ideally suited for low & high traffic, as well as dry & wet conditions, and in both residential & commercial applications.
