For practice, I'm finishing a piece of furniture that isn't too
important. It is a fish tank stand.

I did fine with the top surface, fixing it up and using MinWax
pre-stain Wood conditioner, red oak Wood Finish Stain and Fast Drying
Polyurethane. That's part 1.

I'm now working on the bottom. This is part 2. No fixing up because
its the bottom; I went straight to 2 layers of Wood Finish Stain, sand,
and then I applied 1 layer of Polyurethane. The next step was to sand
it a little with 340 grade paper. I did that yesterday. After that
sanding, all the surfaces I had worked on are sticky and I don't know
what to do.

I think the stickiness is due to getting mineral spirits on the wood.
I did that twice. First, I lubricated the sandpaper with mineral
spirits. Second, I spilled some paint thinner on my tack cloth. When
I used the tack cloth, it left a wet surface behind.

Is tacky the same as sticky?

Any ideas on what to do? My game plan is to wait. Its still sticky, a
day later.

TIA,

Dan
