Existing Ceramic Tile

(Also see Substrates)

When tiling over existing ceramic tile, lightly sand and then clean the existing tile. New ceramic porcelain tile or natural stone can then be installed using a polymer-modified, cement-based mortar, such as MAPEI’s Ultraflex 2, MAPEI’s Ultraflex LHT or MAPEI’s Ultraflex LFT, or a two-part, cement-based mortar and liquid additive, such as MAPEI’s Ultraflor Plus mixed with MAPEI’s Keraply , or MAPEI’s Kerabond T mixed with MAPEI’s Keraply. Always use a white mortar for installations of new natural stone and clean the grout joints while the mortar is still soft in preparation for grouting.
