I'm looking at putting timber look flooring over the top of my slate flooring throughout the whole of downstairs. The flooring I've chosen has underlay already attached underneath it. I've been advised to use Dunlop timber floor leveling compound to smooth out the slate. Firstly, do I need to have a drill with a paddle to mix it or can I use something else? Secondly do I really need to wait 48 hours before I can start laying the timber flooring?
