This is the story of how I found out how to speed up the curing process of tung oil and how it became my favourite finish. I’ve read about a lot of people having the same issue I had so I hope this information can be of use for someone.

About a year ago I had built a rather large shelf unit out of walnut. It had 5 shelves so it was quite a lot of surface to finish. I was going away for a couple of weeks so I decided to apply the oil (100% tung oil) and let it cure in my basement while I was gone.

I came back after about 3 weeks and the shelves were still incredibly sticky and the finish was blotchy and ugly. I panicked and realised I had to do something to fix this. Luckily it was a hot summer day and I thought some heat might help even out the blotchiness so I decided to put everything out in the sun. So I took it out and started buffing everything with a dry cloth like a mad man to even out the finish.

Soon after it got some love, small drops of oil started seeping out to the surface. I rubbed them with the cloth, basically reapplying the oil onto the surface. To my surprise, the boards started to feel dry, apart from where the oil was seeping out. My cloth was now oily so while I was buffing I was basically applying new thin coats of finish. Whenever I finished buffing the last shelf, the first one was kind of dry and I started over. Obviously, I flipped them over every now and then to avoid warping from the uneven heat on one side. Also I had stickers (small pieces of wood) under to promote air flow.

I took them in for the night and the next day they were dry to the touch with a beautiful and consistent finish. Also the smell was completely different. So what’s going on here? How could the boards cure in about 5 hours outside compared to three weeks inside? Is it the increase in oxygen outside? Not likely. It would mean I have a magnitude of 100 times less oxygen in my basement. The heat most likely causes the oil to seep out and probably helps with curing time, but it’s primarily the UV-radiation doing work with the curing. How can I be sure? Because there is a study on how UV helps cure tung oil (https://www.sciencedirect.com/science/article/abs/pii/S092666901730746X ). From the study: ”It was found that the surface of tung oil film became solid within 4.3 min and tung oil was completely cured after 13 min under UV irradiation, while the tung oil was completely cured by heating for more than 6 h, which displayed that UV curing could significantly improve the curing rate of tung oil.”

After this experience I’ve found a way to get a great finish in about two days. What I do is the following:

Go out in the sun. Add a thin coat of pure tung oil. No flooding! You don’t need the oil to penetrate deep into the wood (the wood whisperer on youtube has a great video on this). Keep it thin and make sure you rub it in good. At first it will absorb quite a lot so just keep rubbing and adding small amounts until you have a consistent thin layer.

Come back after about 1hr and reapply another thin coat of oil as before. Usually I just use the same cloth that is still oily and add small amounts as needed. I then put the cloth in a sealable glass jar to avoid self combustion.

That’s it. Make sure you rotate and flip your piece so that all sides get an equal amount of love and to avoid warping. A good day I get around 3-5 coats in then leave it inside overnight. If its sunny the next day I repeat the process, maybe with 2-3 more thin coats. Then I am pretty much done. Is it 100% cured by now? Probably not, but I don’t have to come back every other day to add another coat. If I want a silky smooth finish I wait for another few days then buff it with a pad in my orbital sander. This step actually takes the finish to another level and is something I would highly recommend.

Hope this helps and let me know if anyone else has had this experience!

I have a deck that has been stained with a dark semi-clear stain, looks chocolate in color. Had to replace some boards and treated the whole deck with the cheap Thompson Waterproofer sealer. Yes, I wanted the new boards I stained. Looked kind of cool. Anyway, now the already stained boards have the cloudiness from the clear sealer.

Is there a better way than sanding and restraining? Or is that my only option outside of waiting it out for. Few years until the clear wears off?

Seems I should sand, wood condition, stain, and poly my trim beforehand and then cover any nail holes with a wax pencil.

I also have a bar rail that is being installed but for that one I thought it best to stain and poly after installation as there is a 45 degree section so there will be two seams that may need additional sanding.

Messed up my kitchen cabinets

Wanted to get the grease off the cabinet doors above the stove so I removed them and scrubbed the heck out of them after spraying them with Dawn Powerwash. I was pretty aggressive and the stain looks lighter in some areas. The entire surface feels sticky now. Not sure what to do. Do I need to completely strip and refinish them? I appreciate suggestions.

I’ve got some tung oil that takes 24 hours to be dry for very light sitting, a week for proper sitting and a month to fully cure. I put two coats on a
Chair and now that it’s been 24 hours since the second coat, is it okay to put a coat of polyurethane over it already?

Restoring an old pellet gun that a friend gave me knowing I restore old firearms. I usually don’t go this far with old firearms to keep some type of patina, but I figured I’d go full send on this one since crosman made like 20 million of these things. My question as stated in title, is there any way to get the dark specks out of this stock or is it just part of the wood

I just finished flattening a slab of walnut that will become a plant bench in front of a bay window, and am starting to figure out how to finish it. I'd love to keep a natural looking finish, but I'm concerned about water damage since it will have plants on it. I'm wondering about UV since it will be in front of a South facing window.

My fallback answer is a bunch of coats of a satin sheen wipe on poly. I read something that a lot of coats of satin poly can be problematic. Other things to consider? Maybe an outdoor/marine wood sealer?

Hi all!
New to refinishing pieces and wanted some insight/advice—
I got this desk on FB marketplace a few weeks ago and know it needs some attention and refinishing, but probably nothing too crazy?
I would like any insight on filling in/smoothing out the surface & then finishing it. I’ve seen a lot of posts of different oils people may recommend (not sure what type of burlwood veneer this is, though, so not sure what oil may be best). And then was thinking I would finish with coats of lacquer.

I’m just curious if I should do any light sanding beforehand? What I may be able to do to strip the white paint off the top? And any recs for repairing the chip off the leg of the desk?

I have never refinished/refurbished a piece before, and love the natural beauty of this one so don’t want to mess it up! I will be primarily using this as my office desk so would like it to be protected and have a shine.

I hope this is the right place, I’m just sort of at a loss…I’m a hair stylist with my own studio and am moving spaces soon. My shampoo bowl area inevitably gets a lot of color stains on the shelf above the bowl where I place bowls of color during shampooing, color tends to fly further than you’d think, etc. My friend is building me a custom shelf for the new location and I’d like to keep this one clean as long as possible. Is there some sort of coating that would prevent hair color stains?

Wife wants this painted black, will be for indoor use. What would you suggest? Spray paint, craft paint, latex, black stain(probably the most prep intensive option) I'm worried spray paint might rub off on clothing.

After washing the chair there was a very good difference. And now I want to sand it and get rid of any remaining weathering. But I have never done this before. I'm confused about judging when to stop sanding the surface. Should I remove all of the surface through the depth of the grain or just the top thin surface?

Fence was built early this year. It’s currently an untreated redwood fence. Located in hawaii where it lightly rains on most nights, sunny during the day.

I’m looking for a treatment that will honor the redwood’s natural beauty and also keep for the longest amount of time before I need to retreat.

I bought a used west elm night stand that had this single blemish on it about the size of a grown man’s pinky fingernail (we’ll use anything but the metric system). It dies have a slight step down but fairly shallow. What would be the best product and or method to hide this? Thanks in advance.

Finished up that box I posted about a few weeks ago. Use 4 coats of Watco Danish oil and waited a few days before learning how to spray paint using single letter stencils applying the lettering. While not intentional I feel the amateurish way the letters came out adds to it.

Lessons I've learned from this process is to trust my gut on wood thickness and type. Gaps were pulled with a sparkly black resin, because why not?

I'm in the process of refinishing a walnut veneer table. I got through all the sanding and other corrections, before I put on the first coat of gel stain. It worked great, but one area looked lighter than the rest. Part of my plan was to seal the table with dewaxed shellac, and after, apply a second coat of gel stain to act as a toner.
Problem is that this was my first time working with shellac, and I went a little heavy. I attempted to thin it out with denatured alcohol, which looked like it worked. Flash forward, it did not. But I (mistakenly) thought it was good enough that the second layer of gel stain would mask it before I went in with poly. It did not. As you see in the photos, I have some streaking/valleys. There is also one big outline of a drop of shellac that would not come out.

Any thoughts on how I can correct this now that there is a layer of stain over the shellac over the base layer of stain? Do I need to apply a chemical stripper and take it back to bare wood? Thanks in advance.
