What Customers Are Saying

Customers overwhelmingly praise this thinset mortar for exceptional ease of use and reliable adhesion, particularly with large-format tiles. Reviewers consistently highlight smooth, lump-free mixing, effortless application, and extended working time before setting. The product excels at holding tiles securely on walls and floors, including porcelain and natural stone in high-moisture areas like bathrooms. Many users report deep loyalty, repeatedly choosing it for projects. A few mention isolated adhesion issues, but these are universally attributed to improper installation or substrate preparation rather than product failure. Overall, customers consider it a dependable, high-quality choice for both beginners and experienced installers.

Hold the tile up.

My handy man worked with it, no complaints, but he did about three rows on the bottom first and then the next day he came back and did the rest.

Be Careful Of The Expiration Date (Great Mortar)

Would Recommend

Mapei Large-Format Floor & Wall White Thinset Mortar is a fine product. it's easy to use even if the bed is rather thick. The bond is strong, the spreading is consistent and the wetting is quite good. The no-slump feature works perfectly if water is added properly in accordance with directions. The mortar holds up well outdoors (in appropriate applications)- evening climates which go into freezing weather. But Watch The Expiration Date! Searching six Lowes nearby, every bag was expired.

Good mortar trowels down well

Would Recommend

Mixed half a bag at a time, doing a total of 400 sq ft. Takes a while to mix well, but it has good working time and goes down well with any size notched trowel

Feels soft /brittle after but I trust mapei

Would Not Recommend

I found this product to be somewhat powdery and brittle despite mixing per the manufacturer instructions. I've liked all other Mapei product I've used better.

Would Recommend

I placed my order at 11am, expecting it to be ready by the time I arrived at 7pm. Not only was it not ready, but I had to track down the items myself, load them onto a cart, and stage everything at the front just to get checked out—which took another 30 minutes because the store was clearly understaffed. I asked for help loading the items into my truck due to a back injury, and waited another 15 minutes. No one showed up. At that point, I had no choice but to request a refund and leave empty-ha...

Large tiles? Use this!

Would Recommend

Easy to mix, very strong hold, great for large format wall tiles. Used this on 12x24 tiles for a bathroom wall and would not recommend any other product more than this one.

leaves haze (doesnt get off)

Would Not Recommend

This mortar is very hard to remove from tile after it dries it leaves a haze on tile. Also, it left my bathroom smelling like the mortar. its as if it has trouble drying. Its been 2 months and the smell is just starting to fade a little. My bathroom doesnt have a shower and its not humid where i live.
