I have been using wiping poly for years and love the finish. I am somewhat lazy and have been purchasing the pre-mixed variety. Now I can only find the waterbased variety at my local (24 miles away) home depot. I tried it and hate it.
The paint man informed me that the oil based variety was just the poly cut w/paint thinner but he didn’t know the proper ratio. Does anyone here know what that ratio would be (no guesses please)?

Thanks, Kimball

50/50 is a good starting point, but you can experiment because the ratio is not all that critical. The thinner you mix it, the more coats it will take. I am currently using a batch of 50/50 I mixed up, but I find it a wee bit thin, so I’ll try a bit more poly next time.

I’ve had good luck with 50/50, but like Charlie said it can take a while
One thing to look out for is some are already thinned to a wiping consistency (I think General is like this, and I know Minwax makes one as well, correct me if I’m wrong of course). I usually buy full strength and then thin it myself, since I can’t see the wisdom in spending the same amount of money for what is in essence half the product.

Just to add one more point the exact ratio, as Charlie has said, is not important. And you can use paint thinner, mineral spirits or lacquer thinner. I generally use mineral spirits and cut it to 50:50. I usually have to put on 6 to 8 coats to get the build I like and lightly sanding between each coat. The advantage of mineral spirits is that it takes a little longer to evaporate whereas lacquer thinner will flash off faster. This gives less time for dust nibs to get into the finish but I just happen to like the longer “open” time that mineral spirits gives so that the finish has more time to level out.

I agree with you about the water based product. It has come a long way since it was first introduced but it still is not up to par with the oil based product. Water base poly imparts a bluish tint to the topcoat, which has a rather “cold” appearance. Oil poly gives it an amber color which “warms” up the finish.

I don’t beleive there is a correct ratio, the genral rule is pretty much the thinner it is the more coats it will take, but the smoother the application. I tend to hand around the 50/50 mark too, but honestly, but have used 60/40, or 40/60. I think your best solution would be to use 50/50 as a starting point and adjust until you find a ratio that you get good results with.
