"Bought this '5 minute multi purpose filler' and used it exactly as it says on the tin. Buyers beware! This stuff does not set hard, I was able to dent the filler with my little finger after 36 hours drying time. It's like a soft dry putty, and won't even hold a Rawlplug firmly. A call to Ronseal Technical Support confirmed that this is what they expect the product to do. They tell me it's only a decorators filler for use prior to painting. This is not clear on the tin! Disappointed. However, it doesn't sag and it does smooth well if that's any good."
