FAQs

FAQ
What is the right mortar for my tile size?

Cement thin-set mortars such as MAPEI's Ceramic Tile Mortar and Porcelain Tile Mortar are good for tile up to 15" on any side. 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.

FAQ
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.

FAQ
Can I use MAPEI's Porcelain Tile Mortar for ceramic tile?

Yes, MAPEI's Porcelain Tile Mortar can be used for installations of ceramic tile, as long as the ceramic tile does not exceed 15" (38 cm) on any side.

FAQ
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.

FAQ
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. MAPEI's Ceramic Tile Mortar, Porcelain Tile Mortar, Large Tile & Stone Mortar and Large-Format Floor & Wall Tile Mortar contain polymer and are considered modified.

FAQ
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™.

FAQ
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.

FAQ
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.
