I have to repair a patch (2' x 2') on a ceiling where water leaked in.
The ceiling is plasterboard with a surface that looks like small hanging
droplets of emulsion paint every 5-10 mm or so (early 1970s build). A
plasterer advised me to get some Artex powder, mix it with emulsion paint
and then dab it on with a plastic bag over a soft brush or similar to match
and blend the new surface to the old.
I'm not sure what Artex powder consists of, and I don't what to have to but
a sack of it for such a small area - would a filler
powder eg Polyfiller mixed with emulsion paint be just as effective or must
I stick to the Artex
