What is the open working time of this product once mixed with water?

Asked by: Nikesh
There are two types of mortar ….. the quick set kind which is strictly for the experienced or professional tiler and the regular set kind which is designed for the DIY’er. The latter is the one I used. Latter gives you plenty of time to work with mixed product. Sorry don’t have actual working dry time but believe it is stated on nag.

Is this product good to install 1” thick square cut flagstone on a basement concrete floor. I am installing about 25 sq ft and need about 1/2” bed. Would one 50LB bag be enough?

Asked by: Newman21
I purchased to install back splash tiles but returned it unopened as decided to go with premixed type 1 adhesive instead. 1/2" is a lot of thinset for a base which normally calls for 1/4" trowel teeth so if you go this route .... you are likely going to need double the amount indicated by the manufacturer's coverage ratings.

Mapei 22.7 kg Grey Large Tile Mortar is rated 4.6 out of 5 by 11.
Rated 5 out of 5 by from Excellent product for large scale tiles. Currently tiling a bathroom. I used this for the backer board and 16" X 20 " floor tiles. The shower walls are yet to be done. I found that it is best to store the unused powder in a dry 5 gal pale with a lid. Open bags tend to turn to a rock after being opened for a while.

Rated 4 out of 5 by from Easy to work with I originally bought the Mapei Light Mortar for Tile & Stone at double the cost for half the quantity. It worked, but was it necessary? Only if you REALLY need white mortar...question of economics, really. My job was a tub surround tile installation with 12x24 tiles. Both products apply equally well, but time will tell if there's a long-term difference. This mortar seems to have a lot of sand in it, but maybe that's normal.

Rated 4 out of 5 by from Works on Floor tile to be glued to bathroom Walls dries fast and cures in 6-10 hours . it will glue huge heavy floor tiles on any walls. We glued 24" X 24" floor tiles onto bathroom walls up to10 feet height. no issues. we had to remove one tile that I didnt like, we used Rigid Suction to pull tile off and crack the that heavy thick tile, so this tells us this Large floor mortar has great holding adhesive power!!! *the tile was only on the wall for 20 minutes or less so the curing bond is Great for the wall, working very fast. . The new style of wall tiling now is huge format tiles 24"x24". Iam comfortable it will work on 48"x48" as well. just make sure you use a rubber mallet to tap and vibrate all your tiles of any size so air is removed from behindthe tiles on the floor or on the wall. those people who never use a rubber mallet to tap their tiles will come out with every excuse they been doing this for 35 years etc, those are the ones youdo not want as they have not been educated or not insured from taking inservices from the manufacturer. They are your typical Youtubers. Id avoid carpenters as many are rough and not finishing carpenters. Try to find a young carpenter whose still doing his red seal from the college or a tile setter who use theSchulter system. The Maritimes are notorious for backyard mechanics with no college training cutting cheap corners, theres areason why they arecheap. lol

Rated 5 out of 5 by from Wow...... stuff works It works like a charm. Not very easy to wipe off tiles the next day though. So gotta clean right away
Date published: 2018-12-26
Rated 5 out of 5 by from Beautiful consistency Mixes easily and holds its form very well under 12x28 tiles.
Date published: 2018-05-24
Rated 4 out of 5 by from Good Mortar This mortar is very good and very sticky. I installed the large tile on the wall and after 3 hours I was able to grout it without problem. I gave it 4 stars instead of 5 stars because their wasn’t an option for the white mortar.
