Bondera is an advanced, pressure-sensitive tile adhesive on a roll for wall and countertop tile applications. Bondera Tile Mat Set will replace mortar, thinset or mastic for a fast, easy and clean installation on a smooth flat surface. The tile is directly pressed onto the adhesive and once applied, is ready to grout immediately. Bondera offers results in half the time and without the stress, mess and technical demands of traditional tile setting materials. Just peel the Bondera liner, stick the tile in place and you can grout immediately.
