11168232 · 2021-11-09 · ·

Exemplary methods for installing tile using a reactivatable tile bonding mat is disclosed. The reactivatable tile bonding mat is placed upon a substantially flat surface. Stone, porcelain or ceramic tile is placed and arranged on the reactivatable tile bonding mat in an aesthetically pleasing fashion, in some cases aided by the use of spacers in the joints between the sides of the tiles. Induction, or some other method of heat, is applied to the upper surfaces of the tiles, to quickly transfer through the tile, causing a polymer hot-melt material embedded in the reactivatable tile bonding mat to melt and adhere to a lower surface of the tiles, forming a strong bond. Upon the tiles fully bonding to the reactivatable tile bonding mat, spacers may be removed and a suitable grout may be applied in the joints between the sides of the tiles.
