Can you tile over a painted concrete surface?

I plan to tile my outdoor balcony. It currently has chipping paint over a concrete surface. I have heard conflicting information on whether the paint needs to be stripped or not. I would rather not (of course) but am willing to do if its necessary. Please advise!! Thank you!Can you tile over a painted concrete surface?
You can do it without stripping the paint, just consider the material you use and have a professional do it. That will add lots of value for you. I would scrape the loose paint first though.Can you tile over a painted concrete surface?
depends on how bad it is chipping.





try power washing first to see what breaks lose.





make sure the thin-set (mortar) you use is made for outdoor use.





it will bond to the painted concrete but we are talking about the longevity of the install.
As long as it is etched or a rough surface , it will be fine. Just make sure all paint chips are not loose.


Lowes will guide you in the right direction on what materials are needed.


Me? I would use a sand blaster to clean the paint, hose down, dry, paint a sealer over the concrete like an epoxy to make the tiles adhere better.





Hope you live in a warm place all year around, the mortar in the tiles seem to be weakend over time during freezing %26amp; thawing seasons, then you really have a problem. Problems with water and dirt in cracks causes the tiles to get loose and fall off. Good luck!
you will have to use hydraulic concrete to level the floor than you can put tile over it.
Chip off the loose paint and if the paint is shiny at all, you will have to sand it to a rough finish. Go to Lowes and buy a product called Mega Bond along with the latex additive. The Mega bond is used for outdoor use. You will need this for the expansion and contraction during cold and hot weather. Mega bond is the thinset you will need to set the tiles. Make sure you use tiles that are made from Porcelian or natural stone, don't use Ceramic. Hope this helps.
Are you talking about vinyl or ceramic tile? The adhesion to the concrete is what is important, if the paint is coming off it will not hold the tile down because the glue will stick to the paint. If most of the paint is staying put you can just clean off the flaky areas and stick down your tile. Have fun
