Description
Bostik Big Tile & Stone is a polymer-modified, large & heavy tile mortar used for interior or exterior installations to set all large sized ceramic, porcelain, granite, slate, marble, limestone, thin porcelain tiles, large porcelain panels and dimensional stone tiles. Bostik Big Tile & Stone may also be used for vertical applications. Use over structurally-sound: properly prepared concrete, exterior grade plywood (interior/dry use only), cementitious backer board, Bostik Ultra-Set Advanced, Bostik Black-Top, Bostik GoldPlus and existing, well-bonded vinyl composition tile (VCT) or ceramic tile. Big Tile & Stone may be used for uneven tile and stone thicknesses; or to minimize lippage. Big Tile & Stone white formulation is approved for non-sag applications for tiles up to 12″ x 24″
Application
Apply a thin coat of Bostik Big Tile & Stone™ with the flat edge of trowel to achieve a good mechanical bond to the substrate. Apply additional mortar with the appropriate size notched trowel. If any evidence of skinning or setting occurs, remove and re-apply fresh mortar. Apply mortar to an area no greater than can be tiled in 30 to 45 minutes. Apply tile using a twisting motion into a fresh bed of mortar to ensure maximum contact and bond. Periodically check back of tile to ensure proper transfer (interior applications — minimum 80% coverage; exterior, wet, or plywood applications — minimum 95% coverage). Temperatures must be between 50°F (10°C) – 100°F (37.8°C) during installation. Note: If the appropriate coverage is not achieved, a larger trowel notch may be required. Back-butter each tile with mortar. A finished mortar bed thickness of 1/8″ to 3/4″ is required.
