Is it necessary to get rid of paint on concrete before laying ceramic tiles?

What about an acid etch after the stripper? I know not as effective as a grinder but in principal would it not be roughly the same thing? The stripper removes the paint and the acid etch cleans and scuffs the surface. Could this save her from all the mess and dust?
Just for the the record........

Paints and sealers are known industry-wide to be bond breakers when it comes to tile. It IS NOT RECOMMENDED that tile be installed over any painted or sealed concrete surface.

To remove paint or sealers from concrete surfaces chemicals should not be used, chemical strippers are also known bond breakers. The only industry-acceptable method of removal is through mechanical abrasion. Sandblasting, shot blasting, scarifying, grinding.

The product that I used is water soluble and I of course washed it with a mild soap and rinsed 3 times. I really do think that there is no stripper residue there.

Bud so what you are saying is....

I hope the grinder does not create the amount of dust like a concrete saw.

I'm sure she'll tackle the challenge well. Perhaps even start a blog

Yes, I do get you Bud about the paint removers......
I will just pray that they don't move.......and my clients don't care.......

If I was doing this as a profession and for paying clients......I would definitely hire someone and have it removed mechanically.

tyvm to angus242 for the rubbing alcohol tip. It works... softened the paint & just takes light chiseling afterwards.

My question is the same as the original poster, BUT my floor is not painted. It is only “pain splatters” here & there on the concrete i am removing. Please let me know your opinions about how serious or not serious it is to remove the scattered paint splatters, because i've heard just making cuts in the paint is good enough to get the thinset to make contact with the concrete. And what about the areas where the paint is faded & not dense? I have included a picture of me starting a dry layout. The paint splatters are light orange. Thank you very much.

That amount of paint is nothing to worry about. You might want to remove the door frame and tile under it and re-hang. Or at least back-cut the jambs and tile under them the best you can.

just undercut the frame. don't remove it, no need. place a piece of cardboard on the floor by the frame, then a tile on that. then undercut the frame. that will get ya real close.
