Use caution with this product-short work time
As with all Mapei products they are top shelf but this one should not be used by a novice. You must mix this mortar, use it, and clean up in 20 minutes as it will setup on you and quick- just like it's suppose to. This is not for the novice or the homeowner or the non-professional.

Be ready to work fast. Not for the faint-of-heart.
This product is not for the amateur. Follow the instructions exactly to the letter. Make sure the product is not hot from sitting out in direct sunlight and make sure you use cool water when mixing. If the product is hot before mixing or your water is not cool, the product will harden very quickly and you will not have enough time to spread it . Because this product is related to concrete mixtures, it generates a good amount of heat. That is why both the product and the water need to be cool before mixing. Also, the package instructs you to mix for a full five minutes. Make sure you do this. The reason for this is that any product left unmixed will cause the solution to harden quickly. If the product begins to harden in your bucket, add some more cool water and mix it again for several more minutes. This will buy you a little more time but you still need to work fast. Mix only small amounts at a time. I was able to lay down 10 pieces of 16in x 16in ceramic tile at a time, but no more. The time needed to make the tile straight allowed the mixture to harden in my bucket. That shows hows fast the product hardens. One last thing; do not mix more product in with a previous batch. You are asking for trouble if you do this. The previous batch will cause the new material to harden faster than it would otherwise. Make sure you clean your bucket and tools before you mix up the next batch or the product will become too hard to remove. Good luck and be ready to work fast.
