Very fast drying, 1 minute and you can layer over, 2 minutes and its fully ready for sanding and painting over! Even in a cold room! Nice and easy to smooth over when applying though I use a metal smoother rather than the plastic piece you see at the side pictured but thats fine if you don't have any tools, none needed! Sanding isn't really needed either, I do it just to get a final finish but like I said, easy to smooth over, great for small and larger jobs!
I've used this successfully on skirting boards, small nail holes, holes from 1 x 1 cm to 20 x 20 cm (with use of wooden boarding to secure solid backing) and all turn out beautifully!
Just a little mixing to begin, nothing hard and nothing else needed bar whats in the tub already. What more can you want? ;-)
