Installed 18 x 18 porcelain with sanded grout by contractor. Didn't like it. Removed it and ground the floors down to remove thinset.

Later installed 18 x 18 porcelain with "laticrete fortified" thinset. Had moisture issue and needed to remove 2nd installtion of tiles.

However, the laticrete thinset will not come up. I used a diamond stone grinding blocks and the SCARIFIERS on the same grinder. The stones just gunked up and didn't remove the thinset, and the scarifiers only knocked down the thin set - sort of.

What in the world can I do to get this stuff up so I can level it and put down laminate planks? Thanks for your help.

This Latacrete product--did it come premixed in a bucket?

What is the thin set attached to? Is there tile board under it?
What do you mean by you had moisture issues?

Can't get up laticrete thinset

The thinset came dry, I mixed it. It was applied to a cement slab and I back buttered the porcelain tiles. There was moisture rising up from under the slab that loosened the thinset forcing me to remove all of the tile.

I had to have back surgery and never got back to removing the thin set for months, that's when I rented the grinder and learned that it's not going to come up.

Did the grinding cup look something like this?

I've also used a commercial floor buffer with a set of carborundum stones---this worked very well,but the area was large---not sure how well it would work in a confined space.

Sorry to hear you are having trouble---that is unusual.
