Last night I put on the first coat of wipe on poly on the top for a vanity I’m building. It had a few coats of danish oil that had sat to cure for about 5 days before I applied the first coat of poly last night.

This morning, on my way out the door I took a look at it and it looks very uneven, though I made sure to use full length passes from end to end when applying the poly and overlapped a bit. In other words, there are parts of the top that have a bit of a sheen that looks like some poly has been applied, and other areas that still look like the dull/matte unfinished wood.

Never having used wipe on poly before, I did test on a small sample first and it looked fine. Is this just what I should expect until a few coats have built up to even things out?

What sheen is the poly? And did you stir it well? Reason i ask is if the flattening agents aren’t mixed well regularly it can do this, especially with satin.

What you describe is pretty normal for the first coat. That is why you need more than one coat.

In addition to what SMP has said, in my experience, this is very normal. Just keep going with another coat or two or three. Just before the final coat, you may want to sand lightly with 220 or finer. After the final coat is cured, rub lightly with 600 grit wet/dry sandpaper using soapy water to lube. Wipe it clean, let it dry, and then wax. Smooooth.

BTW, I have found this link helpful tips even when using other brands of finishes, click on the link titled “Step 2: How To Apply General Finishes Arm-R-Seal “

You can shake wipe on poly. Of course only satin has flatteners and needs mixing anyway. No need to mix gloss.

I use wipe on quite a bit. Takes more than a couple of coats to start to see the end product come to life. Plan on 5-6 coats. The last project I did for a neighbor, I used 1000 grit wet/dry with water lube for the final coat.

As stated it takes many coats of wipe on to get the job done. I only use is on projects with a lot of complicated elements that tend to cause drips and runs if I use brush or spray finishes.

I’m curious what wood, final sanding grit, and how you applied the danish oil. It should have sealed the surface, unless you did not keep the surface wet for ~10 min then wipe off, or finished with ~120 grit. Any bleed back after applying the do?

I really like Danish Oil but it takes time to fully cure. With several coats, I wait a longer time than you did.

As others have said, it takes quite a few coats of the wipe on and time to dry and cure. You have to be patient.

3 Questions

What wood?

How old is this DO?

Where was the finishing done, inside a heated home? Out in a shop/garage where overnight temps may still be going into the teens?

Frequently quoted is 24 to 48 hours cure time, but there are so many variables to that. I asked about just 3 of them.

What you are seeing is typical for the first few coats. On initial application, the wood differentially absorbs the poly. Some areas absorb a lot while other areas do not; with subsequent coats things eventually even out. While I am not sure what brand of poly you are using, I have experienced better results with Minwax wipe-on than some of the other brands. Minwax seems less viscous, thus flows on easier and dries faster (other brands seem to stay tacky longer).

It is Satin – Minwax wipe-on, shaken well before using.

Sanded to 220. Wiped on the danish oil, then off. I used Dark Walnut and mainly wanted to use it for the bit of color it lent to the wood. No bleed back either.

Sounds like because I didn’t flood the wood and let it soak in what I’m seeing may be the result of the wood taking up some of the poly?

1) Walnut
2) Maybe a year old?
3) finishing was done in my garage – currently the temps in the garage get close to 80 during the day and maybe as low as mid 60s at night. It did cure for 5 days before I applied the poly.

Perfect, then as mentioned by others, just get 3 coats on there and should be good. Let us know the results. Good luck!
