Never paint stone. Have you tried sanding it?

tried bits

the hearth is cleaning up with sanding. unfortunatly the stains either side of fire are not budging.

This is what Minstersone say

thank you sonia but i spoke directly with minsterstone and they gave me that but no further advice.

Sorry to hear that Gordon. It’s obviously a very porous product, as is solid natural stone. I wonder if it is worth trying a product with low ph as used to clean natural stone? I’m clutching at straws here! Or paint with a masonry paint. It’s not solid stone so why not?

i think i will have to do that . thank you for your help.

This paint is specifically for stone fireplaces. Their page has lots of good reviews with pictures of the finished fireplaces.

i will check that out. thank you again Sonia.

Can i ask what you did in the end please Gordon?
