Generally don't do it! Tiles of what and where ( condition and any previous coatings)? But a way forward can be owatrol esp then bullseye123+ x2coats then top coat & if w/b potentially add a polyvine varnish..
It's for a tiled window sill, it's got original 1940s tiles which have gone an unpleasant nicotine yellow, but we need a quick solution so we can have shutters fitted.
I don't think I could make a window sill that would look good, but painted white tiles would be fine.
Any recommendations for tile paint?
I've tried a search of the thread but it seems to just bring up any posts with the words tile or paint in, which it turns out is quite a lot.
