Ikea Gerton Table Top Desk: Polycrylic vs. Polyurethane to Seal

One of the first things I struggled with when I started dabbling in furniture building and refinishing was understanding the difference between polycrylic and polyurethane. I wasn’t sure when it was appropriate to choose one over the other, how many coats I’d need of either, or what finishes were best. Today I’m going to share what I’ve learned with you, because I’m refinishing my  beech Ikea Gerton table top desk!

Here it is in a photo from our old apartment:

Do you need to stain or seal the Gerton table top?

Stain, no. That’s a personal choice. You could definitely stain it to change its color, but I personally love the light color of the beech wood on the Gerton table top. So I chose to just seal mine (also referred to as “finishing” it).

The Gerton table top comes unfinished, meaning the wood isn’t sealed. That means that it can easily absorb water, for example, leading to those circular water stains we’re all familiar with. It can also absorb stains from food if you’re a slob like I am and eat like a messy monster at your desk.

Let’s talk about polyurethane first. 

Here are some quick facts:

  • Polyurethane provides an extremely durable finish. It can be oil-based or water-based, and it comes in matte, satin, semi-gloss, and gloss finishes.
  • Traditional oil-based polyurethane has a very strong odor and should be used in well-ventilated spaces only, while water-based polyurethane has a much lower odor.
  • Water-based polyurethane dries much faster than oil-based polyurethane. However, oil-based polyurethane is more durable.
  • Both water- and oil-based polyurethane can lead to yellowing, which is lovely when finishing a piece of richly pigmented stained wood—not as lovely when finishing a piece or furniture painted in a lighter color like white or wood with a lighter stain that you don’t want to yellow.

I use polyurethane 99% of the time when finishing stained wood projects. However, I did use a satin water-based polyurethane to seal the tree branches for my DIY cat tree made of a real tree project because I needed them to dry quickly and wanted them to have very little sheen.

Questions about applying polyurethane? I used semi-gloss polyurethane in a post on how to stain and finish wood. The process it pretty much the same for water- and oil-based polyurethane, as well as polycrylic.

And now let’s chat polycrylic:

  • Polycrylic is a durable, water-based finish, which comes in matte, satin, semi-gloss, and gloss finishes.
  • It dries quickly, with only a couple of hours required between coats.
  • It is a thin, opaque liquid, but it does not yellow furniture, so it’s fantastic for lighter surfaces.
  • Since all polycrylics are water-based, cleanup is easy and can be done using soap and water.
  • It should be applied in quick, thin coats. Unlike polyurethane, polycrylic dries so quickly that you can’t go back and smooth out a spot right after you’d applied it.
  • Since it dries so quickly, applying applying polycrylic with a small, smooth roller is a good option, especially on larger surfaces.

If I’m not using a specialized finish, I usually use polycrylic to add durability to painted pieces. I love that the cleanup is so much easier than it is when using oil-based polyurethanes, and polycrylic won’t yellow lighter pieces. The process for applying polycrylic is the same as the polyurethane process.

So what did I use to finish my Gerton table top desk?

Polyurethane. 🙂 When I purchased it, the directions said to oil it regularly with wood oil for protection. Guess what I didn’t do? Oil it regularly with wood oil for protection. It’s now full of stains since I can’t easily wipe it clean. I can’t even dribble water on it without it making a mark. I chose polyurethane because I didn’t mind a little yellowing and had a big can of semigloss on hand already.

HERE’S WHAT ELSE I USED:

(This post contains affiliate links. You can read more about that here. Thank you!)

AND HERE’S HOW I DID IT.

(Remember to wear a mask and eye protection while sanding and working with wood. Follow the directions and warnings from your particular brand. Do not use any tools without proper training, precautions, and supervision. Read my full terms of use here.)

Step 1: Sand

First I gave the entire top and sides a light sand with the 220-grit sandpaper to buff out any stains. I used this nifty little 3M sanding block.

You could also use an orbital or hand sander to do the job. It will be faster and more thorough. But I would only do that if you’re working in an area you aren’t worried about getting messy like a garage, workshop, or outdoors. They are definitely messier in terms of dust flying.

Step 2: Clean & Seal

I wiped the piece down with a rag to remove the excess dust, and then I wiped it down with tack cloth to remove every last bit of sanding residue. I used a small, smooth roller to apply the polyurethane to the entire top and sides of the desk.

Step 3: …And Seal Some More

After the first coat had dried (follow the instructions on your brand of polyurethane), I gave the entire top and sides a light sand using the 320-grit sandpaper to pop air bubbles and even out the finish. Then I repeated step 2 twice to achieve three coats of polyurethane.

And here it is finished before I put anything back on it.

This project was long overdue, and it would have been so much easier to do it had I bit the bullet when I brought the desk home nearly two years ago! But hey, better late than never, right?

UPDATE!

I’m back to update this post about 2.5 years after refinishing my Ikea Gerton table top desk! So I’ve been using it as my workspace top for about 4.5 years and have had it finished for about 2.5 years. It has held up extremely well. There are a few minor scratches from having heavy plant pots on it, but otherwise, it looks exactly the same.

Here are a few updated pictures. If I were to sand this down in the future to refinish it again, I’d probably use my new favorite finish: Varathane water-based polyurethane in matte. My preferences for furniture have changed over the last few years and have trended toward a more natural, less shiny finish. The water-based matte does the trick, and it’s extremely durable. I have used it on my daughter’s wooden dollhouse bookcase build, the cat house side table build, the plywood planter with hairpin legs, and the raised dog feeder I just made.

But I don’t want to refinish this until I need it because it’s heavy and a beast of a project. 🙂

Thanks for the article. Huge help as I bought this table top to go on top of two IKEA Kallax cubbies as a kitchen island for my daughter's apartment t at college. How do you clean the desk after you polyurethane the table top? Thank you in advance.

Hi, may I know the exact Minwax polyurethane semigloss product that was used? I just got the same tabletop and I really like how yours turned out. Thanks!

Hello there! very nice article. I have the exact same table top and legs and I have two questions for you, hopefully you can help me!

1.- I wasn't told at Ikea that I needed to apply anything to the table. Ikea is more than 40 minutes away from home so instead of going back there I picked up Howard's Feed n Wax > https://www.amazon.com/Howard-FW0016-Feed-N-Wax-Conditioner-16-Ounce/dp/B001BKQYGW/ref=sr_1_1?ie=UTF8&qid=1494180367&sr=8-1&keywords=howard+feed+n+wax at Home depot. I've only applied two coats but just today I put something on top of the table top and It stained it a bit. I was able to remove the stain with a damp cloth but now that part feels rough and not smooth like the rest of the table top. What else should I do? should I apply more coats of the Feed n Wax? should I apply something else to it? is this product enough to protect the table top from normal wear? This is my workstation desk so i'm going to be using it daily.

2.- Were you able to screw your Ikea legs to the table top? Right now my table top is just laying on top of the legs and it's not secured. I know there are holes for screws, but they are for different desk legs.

Hey there! I'm not familiar with Howard Feed N Wax specifically, but I generally avoid furniture oils and waxes for high-traffic areas. Although they can be beautiful, they just aren't as durable as a polycrylic or a polyurethane. The only tricky thing is that if you want to do a polycrylic or polyurethane on this now, you'll need to sand the wqx off completely. As for the legs, I actually didn't screw mine in either. The table top is so heavy that I felt comfortable just setting it on top...and even heavier once I put my computer and plants on it!

I just read the above comment, similar to mine. What is a wood conditioner for?

Brittany Goldwyn

It's to even out the wood so that it will take a stain more evenly. I almost never use it, but others swear by it!

Hi I just bought a gerton table top from Ikea. I plan I using in my kitchen. Can I stain first than polyurethane?

Brittany Goldwyn

Yep, you sure can! Just follow the directions on your stain's can for dry times.
