Hello everyone, Happy Thanksgiving!

I am a general contractor in South Florida and have a new crew installing a patio floor. Note the patio floor has uneven terrazzo, and a ton of prep work required, definitely not a easy job. One layer of terrazzo on top of another. 90% of the top layer was removed. There were some plumbing patches in the slab. My tile contractor has installed a leveling bed of Laticrete 252 (thunder) on top of the terrazzo. I have concerns as this is the wrong product for the job. Typically I am used to a self leveling product or a mortar bed. Never seen someone make soup of 252 Thinset and pour it as a leveling bed. Definitely know this goes against the manufacturers recommended installation methods. Will this last or is this garbage? Looking for advice whether or not to pull the plug with this tile contractor
Wood Flooring Floor Building material Road surface

and move on to the next one. Your thoughts?

Being the abortion that it is, deal w/it. Did he not give you a plan of attack or did you not ask. Why didn’t you take it all the way down to slab

Hey Mike -

thanks for your reply. Definitely, the goal was to take off the top layer of terrazzo 100% and get all the slab even (chipping/bushing) prior to starting. Never discussed what material would be used for what and where. Just have concerns with Laticrete 252 thinset being used as a leveling bed. Hard to find crews right now, actually paying 3x the average rate. Just don’t want to pay 3x for something that is not going to last. Wondering if I should pay the guy for time invested and switch to another crew. Maybe others have used Laticrete thinset 252 as a leveling bed and had no issues and I am overthinking it.

Main question is if Laticrete 252 thinset being used as a leveling bed, okay or not? Trying to confirm by fears and move on, or put them aside (as it’s not an issue) and continue.

Terrazzo, is by definition Concrete, why remove it? just pour over to level, maybe grind for improved bond? Match old CJs in Terrazzo...

A week ago, I finished a job that required leveling the floor and arranging ceramics. A friend who "deals" with such jobs offered to do the job for me. When he arrived, he immediately started with the story that the existing concrete should be demolished entirely. A new slab should be made, and then various isolations, leveling, and so on. I did not agree with his suggestions and decided to call paving contractors dublin, who did the job without much discussion and philosophy. I have the impression that every repairman guy thinks for himself that he is the best and knows what no one else knows. If you want pictures of the mentioned work, contact me via messages.
