Is it wise to use premixed mortar on basement concrete floor of washroom for porcelain tiles? If yes, which brand is good. I have seen reviews, and most customers complain about the long drying time.

Tiling is the bigest portion of all our renovations and we would not use pre-mixed mortar for anything.

I would use a good quality Thinset appropriate for your subfloor. Since I don't know if there is anything on top of your concrete, make sure you read the instructions on the bag to see if it appropriate for your application.

You will have a choice of modified or non-modified and if you have access to a tile store, I would go with Keisel or Schluter Thinset.

Good luck

Thank you, Victor. Should I install the tiles directly on the concrete floor?

This is a great question, I personally haven't worked with pre mixed mortar but in my experience I would say to stay away from it. Neither myself or any of my quality tile installers use such a product and would not recommend to a client. If it is like pre mixed grout, complete garbage. Hope this helps

Hi Syed,

I'm not sure that one brand would be that much "better" than the other. Just be sure to carefully read the label!!!

I have used the product without issue. I only use it in smaller projects...based on its cost alone.

It wont be fully cured for 72 hours, but typically can be walked on after 24hrs.

Its fine on a basement floor. Just prep and primer the floor accordingly.
