Painted Breeze block.

[Billy Hunt]

I have a small job to do in a converted garage/utility.
Walls are painted breeze block in good order,customer wants to avoid boarding out! Any issues with tiling small wall ceramics to this back ground?

Not tried it myself. Would there not be a moisture loss from the addy even if several coats of primer were used ?

i would remove as much paint as poss , if you cant remove i would score the walls to give a good key

Thanks guys,don't want to use a ready mix addy as never use (diy stuff) hopeing someone as tiled to this surface before without any issues,it's only a dog shower so no major worries ,but don't want to be caught out by breeze block and paint.
Anyone??

With breeze being having such a course surface the only thing that I can think of is to sand (electric or by hand) the surface to remove any paint back to the breeze block.....

If I had to do it I would use a rapid adhesive so it wouldn't put to much mosture into the substrate but wouldent recommend it
