LATICRETE 4-XLT is engineered to address the specific challenges of installing large-format tile (LFT), defined as tile with at least one side longer than 15 inches. These large tiles are susceptible to 'sinking' into the mortar bed and 'lippage,' where one tile sits higher than the next. The unique, non-slump formula of 4-XLT allows the mortar to hold the weight of these tiles, keeping them perfectly flat and level during the curing process. This mortar is suitable for both interior and exterior installations on properly prepared concrete or masonry surfaces. Beyond its slump-resistant qualities, it offers high bond strength that prevents hollow spots, which are a major cause of cracking in large-format tile floors. When using 4-XLT, we recommend using a large-format notched trowel to ensure maximum adhesive transfer to the back of the tile. By investing in a dedicated LFT mortar, you significantly reduce the risk of structural failure and aesthetic issues in your finished floor.
