Okay, I’m putting the first coat of poly on a chest of drawers I’m refurbing for my kids, it dries and this is the result;

Have you ever experienced anything like this? What do you think would cause this effect on a finish? Moisture? Wrong stain? I’m at a loss.

It only happened on one side of the cabinet so I sanded it all the way down to the wood and am waiting, with some hesitation, to refinish it.

The stain I used is Minwax Natural 209 on top of which I used Minwax Clear Satin Poly. Could this combination have caused the problem? I look forward to your comments.

Thanks for your help.

Is the poly, oil or water based ?
what did you use to strip the old finish off with and did you apply any pre-stain conditioner to the Pine ?

It looks like it wasn’t stripped enough, or there might be some sap from the pine, or SOMETHING in between your stain/poly and the wood.

I’m not totally taken aback by the fact that it may not have shown after staining. You DID say you went with their clearish/natural stain.

I’d strip it down, and start again, and try to strip out some sap. (it looks like you’re working with some really knotty pine, which means plenty of saps).

We had a similar issue once with some teak; wanted to re-finish it, but my wife’s mother, when she had lived, had lemon-oiled the thing within an inch of it’s life.

Sadly, we ended up painting over the wood, as I wasn’t really prepared at the time to find out how far we had to go.

If the old finish was a regular shellac and not dewaxed, the new poly will not adhere. I would either sand down to raw wood or look at putting on a dewaxed shellac and then try to use the poly in a test area.

as has been said above…looks like some of the old finish is still there….sand it again and dry a degreasing agent befor refinishing…..if it’s sap causing the problem then the degreaser might help neutralise it…good luck

-- just get stuck in and have a go!!!
