The floor has had 2 sanding passes made and it is now time to trowel fill. I will be using Woodwise full trowel filler. How long does it take to dry enough before I can sand? Will it be a couple of hours or overnight? I can't seem to find this information anywhere and am trying to plan the rest of my attack.

Thanks for any tips.

Depends of course on air temp & humidity, and how large the gaps are, but it should be dry by tomorrow morning.

Most water based fillers like Woodwise dry anywhere between 15 minutes and a couple of hours depending on how large a gap is filled. I don't know if this is helpful to you but I stopped using woodwise filler because it shrinks and cracks more than any other filler I have used.

The best water based filler I have used so far is timbermate. It does a great job compared to other water based fillers. Much less shrinkage.
