Hey! I just signed up for this site hoping for some advice. Sorry in advance for the long post. Im refinishing an old high chair tray and I went wrong somewhere and I’m trying to avoid making the same mistake twice. I stripped and sanded the tray, stained it with Minwax oil based stain and gave it a couple of coats of oil based poly. Everything was peachy at this point even though I didn’t use and sanding sealer or wood conditioner. The stain looked great and the finish was solid. But then I decided I wanted a matte finish. So I got a spray can of dewaxed shellac and gave it a couple of coats. Seemed okay. Then I put a coat of water based matte poly on and the finish failed :( Flaked right off. I know oil and water don’t mix, but I figured the dewaxed shellac would solve the problem. I’m going to sand, seal, and stain again but I’m trying to figure out how to give it a matte finish. Should I just let the oil based stain fully cure and go straight to the water based poly? I know that sounds like it wouldn’t work in theory, but I read on Minwax’s site that it’s okay as long as it’s fully cured. If there is another option got finishing that would be waterproof, durable, and food safe, let me hear it :) thanks in advance!

Niki, it should have worked if the oil products had fully cured which can take weeks. How long did you wait before applying the shellac?

Have you tried just knocking down the poly with steel wool after it cures? Seems to me that you are laying down too many layers of different stuff, which is usually a hit or miss venture :)

Cheers,

I’m more than a little surprised that you had that problem, given that you used the dewaxed shellac. As Art said, you need to give the oil based stain plenty of time to cure. This can take several days if the weather is cool and/or humid. To be totally safe, you would probably do best if you use a waterborne stain with your waterborne finish. It would be risky to apply a waterborne finish over an oil stain without a shellac sealer, unless the stain is totally cured. I wouldn’t want to risk it. To answer your final question, consider something like a pre-catalyzed lacquer. Mohawk makes a pre-catalyzed lacquer in an aerosol. It sprays like a regular lacquer, but is a lot more durable.

Thanks for your responses! I gave the stain a few days to dry, but maybe that wasn’t enough… or maybe I sprayed the shellac too thick….

I tend to be a little too impatient for this hobby. I’m working on that :) I sanded it down and I’m going to give it another go. I’ll keep you posted!

Hey, again! I have a new question :) I acquired a different old high chair. It’s been in the family for years and is sentimental. So I hurried up with the old one and used a water based stain (which I despise using) and a water based poly. I sold it and now I’m moving on :)

This new old high chair is filthy but in other wise decent shape. It’s dry and rustic looking. I like the way it looks, though. So I don’t feel the need to strip and sand. Someone said to seal it with Danish oil. Is that safe? Do I need to be concerned about any old finishes? I usually either strip and sand or paint so this is new for me.

I don’t use Danish oil over anything but bare wood. From my experience I don’t think it would work very well.

Welcome to Lumberjocks. I hope to enjoy it as much as we do.

Niki, since you don’t know what the old finish is, it might be prudent to clean the chair thoroughly, sand lightly with 220G then apply a couple coats of shellac and finally 2-3 coats of polyurethane. You will be able to use either oil or water based product. Any finish is safe once it has completely dried/cured. HTH

Thank you so much! I’m glad I asked before I wasted time with the Danish oil. I will be taking your advice and I’m super excited :) a high chair fit for a little prince :)

Have your say...
