Tile over stained concrete

I stained my concrete patio w/chemical stain and a water based sealer. It was a failure. How do I remove this product to install ceramic tile on the concrete. Would pressure washing surfice?

At the very least, you would need to grind the slab to remove the sealer. I would expect the solvent base of the stain that carried the pigment had evaporated before you sealed it. You can't prep with chemical strippers and your slab will need to absorb water.

If Bud comes along soon, he knows a lady who is one of the leading experts on concrete staining and also runs a message board on the topic (or atleast used to) and maybe your first attempt could be fixed?

Did Bud ever get ahold of the expert on concrete staining? We have a project that went bad and we want to tile over our stained concrete job in the future. If possible we would like to not have to grind the floors again. We already spent $1200 on this surface and we hoped the work done to prep for the stain could carry over to a tile job. Ideally with minimal prep, we could just tile over it. I got a recommendation below to use epoxy thinset to set the tile directly ontop of the stained concrete The concrete has one layer of polyurethan.

"the epoxy thinset will adhere to the stained concrete. If you go with tile that would work fine"

Do you think this sounds ok or should I realistically expect to have to grind the floors again?

Thanks

Here ya go!

Thanks!

I agree, I do decorative concrete and I am certified by Ardex in decorative concrete and I also have been doing tile for 20 years, If you use an epoxy thinset, it would take an act of God to remove that tile. I would think just priming the concrete with latex would make any latex modified morter hold very well. I would call the tech rep at the company who makes the thinset and ask them because if they will guarantee it and it fails, they would be responsible.
