Do I have to use Avaire Flexible Grout when installing Avaire Tiles?
A. Yes. Avaire is a floating floor system, and requires the use of the specially formulated Avaire Flexible Grout. Other grouts are not sufficiently flexible to handle the movement associated with a floating surface, and will void the 10-year limited warranty. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
