QEP® Tile Beater Block is designed specifically for installing large porcelain tiles. It helps firmly set tile into place. By gently tapping the tile, it eliminates air bubbles trapped between the tile and adhesive. This process is critical for achieving a level installation and eliminating voids that could compromise the integrity of large format tile assemblies. Measuring 15" x 6.75", and made from durable rubber, the Tile Beater protects your tiles from damage during use. Designed larger than most on the market, this Beater Block delivers efficiency with every use. Recommended for all large-format tile installations per the NTCA Reference Manual.
