Topic tags/keywords: polyacrylic refinishing wood

I don’t have much experience with wood working but decided to refinishing some wood furniture with paint and polyacrylic. I completed at least 3 coats of polyacrylic left it to dry for nearly a week but it has now immediately been marked by the first things I have put on it. A cork coaster with a smaller plant and a small glass candle holder that had a textured bottom.

Do I just need more coats of polyacrylic to create a harder finish or is it likely I messed something up in an earlier step?

I’m assuming that you’re talking about Minwax Polycrylic finish…
How long did you allow it to cure between coats?

Welcome to Lumberjocks!

+1 how long did you wait between coats, and how long has it been since finished was applied? How long did the paint under the poly-acrylic cure before top coating?

- It requires ~30 days for most single part coatings to become fully cured. Thicker the film build, the longer it will take. If you have 3 coats of paint, and another 3 coats of polyacrylic on top, you could be looking at several months for cure all the way to bottom with indoor temperatures.

- Polyacrylic is not a hard finish. It is just acrylic window pane. It will scratch or deform easily with high levels of pressure. I would personally never recommend it for table top. If you want a hard coating for table top like used on commercial furniture, need to use post catalyzed conversion varnish, with second choice being a catalyzed lacquer that is easy to repair. Single part solvent based polyurethane (like Arm-R-Seal) is only a little harder than acrylic, plus it takes over a month to fully cure. If you want a hard polyurethane like that used on bar tables, need to use a commercial 2 part polyurethane coating.

Finishing table top is not as easy as manufactures label on side of the can makes it seem. :-(

Cheers!

What kind of paint?

While polyacrylic isn’t good, the problem is more likely the paint underneath. If it’s latex or some derivative of house paint, there is your problem

I’m also wondering about the paint part. A little more description of exactly what you did might be useful.

When you say “it marked”, do you mean that you see the texture of the object impressed into the surface?

I think the LJ’s above have nailed the answer, I did this pedestal set a few years ago and got advice from fellow LJ’s to cover the paint with WB poly to give extra protection. I used brush/roller to apply a contractor grade white latex paint, allowed a couple of days for it to fully dry and then used the cheapo HF HVLP gun to shoot a WB poly straight out of the can for 3 coats with a few hours between each to dry. A final quick sand with an extra fine scotchbrite and then a coat of paste wax. That was over 6 years ago and they mostly live in the lobby area next to some benches and get regular heavy use and still look great.

- IndianaWoodworker

I added each coat 1 – 3 days later.

It was a slow evening project that took about 3 weeks to finish, partially because I sanded a spot too much on a leg of the peice and had to repaint the leg) and partially because a hair dried on the poly layer so I had to start again.

Yes it is texture impressed into the surface. A felt pad left a mark that looks like a wool imprint and the bottom of the candle holder left tiny ring of indented dots.

The painting had been finished for a week or two before the first polyacrylic coating. Then the price sat for over a week. The information I could find said that it should be safe. The process and quite slow so it didn’t seem like I was risking the layers not being dry enough.

It was a water based furniture paint, so interior melamine.

If the paint layer are too soft/not cured long enough I would need to strip everything and start again? Could a better end result be achieved with the same materials?

I suggest you look for chalk paints or any water-based paint. This was my dilemma when I was trying to repaint the metal part of this furniture. When I decided to switch paints and purchased from this Frenchic furniture paint seller, I only had to wait for like an hour to apply my second coat. And with just two coats, you can already see the fine finish. You just have to make sure that you are getting an authentic Frenchic paint to guarantee you a quality finish.
