SOLVES MOSAIC TILE ALIGNMENT PROBLEMS - TILE BOOST is designed specifically to bring thin mosaic tile out to plane with thicker field tile. This wide-format waterproof shim keeps mosaic tile perfectly flat while installing bathroom wall tile, backsplash tile, and shower tile without uneven surfaces. INSTALL MOSAIC TILE AND FIELD TILE THE SAME DAY - Traditional tile installation methods require ledger boards or waiting overnight. TILE BOOST lifts the thicker field tile up while supporting the mosaic band, allowing installers to complete tile installation above the mosaic immediately and finish projects faster. PREVENTS MORTAR OOZE AND SAGGING MOSAIC - Thin mosaic tile often suffers from excess thinset squeezing into grout joints or sagging during installation. TILE BOOST creates a controlled spacing system that prevents mortar ooze and keeps mosaic mesh backing tiles perfectly aligned. WATERPROOF AND BUILT FOR PROFESSIONAL TILE INSTALLATION - An 1/8" thick shim that BOOSTS thin mosaic tile out to plane, and BOOSTS thick field tile up, allowing for same day wall tile setting above mosaic strips. This is the revolutionary and patented new way to build up mosaic tile AND support the tile above them. Tile Boost is white ABS plastic that is 1/8" by 12" by 12" and has grooves every 1/2" to allow for easy scoring and snapping to size. DESIGNED BY A PROFESSIONAL TILE SETTER - After 15 years of installing tile, the creator of TILE BOOST developed this solution to eliminate wasted time, messy mortar buildup, and costly redo work when installing decorative mosaic tile bands. After 15 years of installing tile, Greg realized there had to be a better way to install thin mosaic tile bands on vertical surfaces. Tile installers typically had two frustrating options. They could install temporary ledger boards to hold up the field tile above the mosaic tile band area, return the next day to remove the ledger board, and then install the mosaic tile. This meant an extra trip, an extra day of work, and more labor cost. The other option was building up the substrate with mortar, waiting overnight for it to dry, installing the thin mosaic tile the next day, and then coming back again to set the field tile above it. This process wasted time and money and still left installers dealing with mortar ooze and uneven mosaic surfaces. So Greg set out to design a better solution. After early sketches, rough prototypes, and eventually a 3D printed model, TILE BOOST was born. TILE BOOST is a waterproof wide-format shim that brings thin mosaic tile out to plane while keeping the installation perfectly flat. At the same time, it lifts thicker field tile up just enough to allow immediate tiling above the mosaic band. This simple but powerful tile installation tool eliminates common mosaic tile problems including: Thin mosaic tile sitting too deep behind thicker tile Sagging mosaic pieces during installation Mortar squeezing into grout joints Waiting overnight before installing tile above the mosaic With TILE BOOST, installers can set mosaic tile and field tile in the same session, dramatically improving installation speed and consistency. Whether you're installing a bathroom backsplash, bathroom shower tile, or decorative mosaic band on a wall, TILE BOOST simplifies the entire process. For contractors, tile setters, remodelers, and DIY installers looking for a smarter way to install mosaic tile bands, TILE BOOST delivers a faster and more reliable tile installation solution.
