TEC 123 Double Duty Mastic, 1 Gallon

TEC 123 Double Duty mastic is a ready-to-use adhesive for setting ceramic and porcelain wall tile without mixing thinset. Open the pail and trowel it straight onto the wall; it grabs fast and holds tile in place while you work, so it is a go-to for backsplashes and dry-area walls. It is the setting step for anyone who wants a no-mix adhesive.

This one-gallon pail handles backsplashes and smaller wall areas. Spread it with a notched trowel over clean drywall or backer board, then press your tile in. Use it on walls in dry areas rather than continuously wet zones.

Pros keep mastic on hand for quick wall jobs where mixing thinset slows them down. Tile Outlets stocks the one-gallon TEC 123 for backsplash and wall tile.
