I have been using polyurethane finish, mostly for shop furniture. I use Minwax Wipe-On Poly, as well as a Minwax water based polyurethane. These are easy to work with, but they don’t yellow the wood at all, which is something I would like to see in a finish. Is there a good polyurethane finish that will slightly yellow the wood the way lacquer does?

I have the same complaint about General Finishes Exterior 450, which has come highly recommended. I use it on birch plywood crates that stay outdoors, and after three coats it seems to work very well. But I was hoping it would yellow the wood the way a good spar varnish does. Can anyone recommend a goo exterior finish that will give me what I want?

I use Deft Poly for outdoor projects. Actually it was used on an exterior door that is mostly sheltered from the weather. It is about 6 years old, and it’s holding up great. I doubt there’s any long-lasting finish for outdoor furniture, but in this semi-sheltered spot my door has held up great.

You can use the same thing as you have, just add trans-tint. Honey Amber, I believe is the color I use, I add just a small amount in a ml measurer….I got at a pharmacy. I believe I used 1 ml per every 8 oz. Now I sprayed this, but I can’t believe it would matter the method of dispersion. I found the water based to be much “clearer” than the oil base, but wipe on should be oil based and naturally warmer. You can still tint it to be whatever you want with trans tint.

You can easily mix dye with most hobbiest finishes, not sure about some of the 2- part stuff. But for oil based, I use wd lockwood powders and use naptha to dissolve, and for lacquer, and shellac, and water based use transtint. You may find this interesting reading.

The key word you said is “outdoor”. Only spar varnishes are recommended for outdoor applications as they contain UV inhibitors. None of your poly finishes do (that I’m aware of). In addition, a spar varnish pentitrates into the wood minutely vs. sitting on top of it like the poly finish does. It’s the liquids that penitrate into the wood that darken it.

I’ve used several over the years and what I like best is no longer available due to EVA regulations. If you can find the old Behrs Spar varnish with an oil base, at H.D. grab all you can get. It’s the oil base that makes the stuff last the longest and really sink into the wood IMO.

I need the spar varnish for these plywood boxes I make for storing and transporting firewood:

Also other similar items that live outdoors.

Just curious, but seeing your picture, I don’t understand the need for a finish that “will slightly yellow the wood”. The wood in your boxes is clearly seeing some rough duty and has already received a rich “patina” from the school of hard knocks. I would be looking for the most durable finish I could find and leave the yellowing to Mother Nature. Just my opinion.

It is interesting to have someone looking for a finish that yellows the wood. There are countless threads here from posters looking to avoid exactly that!

oh – I thought you were working on wood lawn furniture or something.

since those boxes are already painted – I would suggest a 30 year latex house paint.
which will hold up way better than varnish. once varnish is chipped or scratched,
it goes down hill quickly if not maintained. (like a Chris-Craft boat).
and the paint dept. can match the blue stripe on the camper and you would be jam up and jelly tight.

Agreed paint or an opaque outdoor stain is the best choice.

Have your say...
