Yes, MAPEI's Mosaic & Glass Tile Mortar, mixed with MAPEI's Polymer Additive, can be used in submerged applications such as pools. A 21-day curing time is required before filling the pool.

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 Mosaic & Glass Tile Mortar contains polymer and is considered modified. MAPEI's Polymer Additive can also be added to enhance the polymer content.

FAQ
What is the advantage of using a liquid additive like MAPEI's Polymer Additive?

Liquid additives such as MAPEI's Polymer Additive improve the overall performance of specialty mortars such as MAPEI's Mosaic & Glass Tile Mortar by increasing flexibility, enhancing bond strength and boosting moisture resistance.

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. Do not add more water if the product begins to thicken. If you are using a liquid additive such as MAPEI's Polymer Additive, keep the correct ratios of liquid additive to mortar powder, do not add water, and adhere to the mixing and resting times. Use a drill rather than mixing by hand. Do not add more liquid additive or add 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.
