Re: diluting oil based polyurethane

said by aurgathor:

I have some leftover polyurethane for floor (1/2 gallon exterior & 1/2 gallon interior) and they both appear significantly denser than when I first used them. What would be the best to use to dilute them?

TIA
BTW,what are your plans for the poly? I would advise against mixing the 2 as exteriors polys are less durable than interior versions.(hence the need for soft deck shoes on a boat deck vs bowling alley finishes). Also,if its been sitting a while be sure to strain it before use and avoid the little hard bits that might have formed over time.

I just want to put one coat on the top side of some 3/4" particle boards (floor for a walk in closet) before assembly. (I will put on another coat or two later on, but that won't happen for a while)

When you say mineral spirit, you mean just paint thinner, or something more specific?

BTW, the polys are from Home Depot; Minwax fast drying polyurethane, and Minwax indoor/outdoor helmsman spar urethane, both clear semi-gloss. I last used them 3 and 5 months ago.

When you go to the store you will see containers marked as mineral spirits, and others marked as paint thinner. I don't know what the difference is, but they sell them in two different containers, so I'm guessing they are different. I don't really know though.
