FAQs
What is the right mortar for my tile size?
If your tile has any side longer than 15" (38 cm), you will need a large-format-tile (LFT) mortar such as MAPEI's Large Tile & Stone Mortar or Large-Format Floor & Wall Tile Mortar.
Can I use MAPEI's Ceramic Tile Mortar for porcelain tile?
MAPEI's Ceramic Tile Mortar should not be used with installations of porcelain tile.
Can a gray mortar be used to install natural-stone tile?
MAPEI recommends the use of white cement-based mortars with all installations of natural stones. Stones that are labeled as moisture-sensitive should be installed with an epoxy-based mortar.
Is a polymer-enriched mortar the same thing as a latex-modified mortar?
Yes, there are several terms used to describe a cement-based tile mortar that contains polymer such as latex-enriched, latex-modified, polymer-enriched and polymer-modified. Large Tile & Stone Mortar and Large-Format Floor & Wall Tile Mortar contain polymer and are considered modified.
Can I tile directly over clean drywall and drywall patching compounds?
Drywall and drywall patching compounds must first be primed with MAPEI's Primer T™.
What is the proper way to mix a cement-based mortar?
Be sure to follow the packaging instructions carefully when mixing. Keep the water-to-powder ratios correct and adhere to the mixing and resting times. Use a drill rather than mixing by hand. Do not add more water if the product begins to thicken.
What trowel size should I use?
The trowel size is determined by the size of the tile being installed. Generally speaking, the smaller the tile, the smaller the trowel notches; the larger (or longer) the tile, the larger the trowel notches. Refer to the Lowe's mortar selection chart for more information.
