I'm just about to lay a 13mm t&g floating timber floor and have a huge tub of Super PVA glue (made by Unibond)that I bought a while back. The question is, can I use this or should I be using a waterproof glue. I noticed SF sells a flooring PVA, whats the difference? My old man says all PVA is waterproof when dry? The floor will continoue through an open plan kitchen but not the bathroom. Thanks for the info.
