   It would be helpful if you said what your deckboards are, and what the exposure is, (southern, etc). Also how the Thompson's was applied.

   No one can give you a good answer until they know that, even if they think they can.

   The floor is T&G fir, it's a covered porch with a due west exposure. The TWS was applied with a brush.

   My guess is that if water will still bead up on it so will any finish that you try to apply.

   One good thing about Thompson's is that it does not last long.

   Agreed -- in fact, when I saw the title of the thread, I figured that I'd just reply to let the TWS sit for six months, because I don't think it would last more tha about four.

   Then I saw that the original poster noted that it's been six months already..........

   Unless you're the lead dog, the view just never changes.

   Alkyd base, but perhaps someone knows something else that would work.

   I'd sand it and thin the first coat a bit, and spend some time getting that first coat on well. Then two full coats.

   You could Lapoxy the first coat, but I see peeling in the future.

   It's my understanding that Thompsons is primarly wax dissolved in thinner, that's why it beads.  That would suggest an oil base primer before anything else, which wouldn't be a bad idea on wood, anyway.

   If it is wax dissoled in thinner, A wash with Naphtha should help remoe it.

   Yeah, but could, with a small spark, remove the deck as well.

   I've used Tompsons as a sealer both indoors and outdoors and never had a problem. I've always covered it with polyurethane--Clear in kitchens and bathrooms and on outside porch floors (including fir) with polyurethane based paints. So yeah it works great, but I would not trust anything Alklid or latex based.

   Not sure what you mean by polyurethene based paints, since there are oil based poly and water based poly both.

   And painter worth his salt will be doing some sanding prep no matter what the condition of the old Thompsons or other seal anyway.

   Thompson's web site was no help, but this guy waits a week.

   This product, per the SDS, contains Paraffin wax. This means you will have to strip or sand all treated surfaces before you apply any primer or finish. While good quality oil based primers will be compatible with the Coconut Oil Diethanolamide, they will not tolerate wax well. Anything you attempt to coat the deck with, will have poor adhesion if you do not properly prepare the deck. Thompson's will not wear away in four months... Unless in was not properly applied. If properly applied it is supposed to last for up to 10 years. Fortunately TWS is easily stripped using acetone.
