Is polyfilla just shit, or am I doing something wrong? I've got some of the powder stuff that I'm using to fill some shallow blemishes in a plastered wall. No matter how I mix and apply it, I can't get it to set any harder than, say, dry meringue. After 24 hours I sanded it and brushed the dust off to prep it for painting. When I gave it a final wipe with a damp rag, it just wiped huge amounts of it off. How is that meant to stand up to being touched, or can you only use it in areas where it will never ever be brushed by the clothing of someone passing?
