I have a we utility type room that's had part of the wall re-plastered. I need to give it a lick of paint. I was thinking of using Sandtex fine textured thinking this will mask any blemishes in wall. Any thoughts.
Sandtex is a microporous finish so is ok, can be used over emulsion, see linky. Same applies to Sandtex smooth masonry paint. http://www.sandtex.co.uk/products/sandtex-fine-textured-masonry-paint/
Remember, this will be applied to an internal space and will have had a couple of mist coats underneath.
Stone needs to breath, & slapping cement render over it is going to cause serious problem, as he said in video, lime mortar, & lime render, both will let moisture escape unlike a cement finish.
The secret is proper preparation, got sandtex smooth on the inside walls of outside bog & ultilty room, been there six years, hasn't peeled yet.
