Hi
We have a blockwork retaining wall which was smooth rendered then left for a year before painting with Sandtex smooth masonry paint. This was done last summer but a few weeks ago I noticed that it is bubbling in places, so I will be removing the bubbling paint before repainting. Is there anything I can do to prevent this happening again?
Thanks in advance for any advice.
