Topic tags/keywords: lathe finishing question

I’ve done some research on water borne finishes. I’ve only used oil based, primarily oil based poly. I was recently introduced to water borne finishes via YouTube. My wife is completing turning projects, especially bowls, and i woukd like to find a finish that doesn’t require having to wait several hours for poly to dry. What are your experiences with water borne finish and would you recommend it?

If you want fast drying, look to shellac or lacquer.

Thanks, Rick. Is there any down side to shellac for turned products? My wife likes a high shine. I know shellac is significantly more expensive than regular poly, so I have avoided it.

Shellac won’t work well for holding liquids but otherwise is fine. Here they are about the same price. Many turners combine shellac and oil to make a friction polish.

Great information. She is new to turning, so there has been a lot to learn. I like the idea of friction polishes and just purchased Shellawaxs for her. Thanks, Rick.

Captain Eddie uses and suggests “O. B.’s Shine Juice”.
I haven’t tried it, YET!!!
It is a simple mix:
1/3 Shellac
1/3 DNA (Denatured Alcohol)
1/3 BLO (Boiled Linseed Oil)

Store any unused “juice” in a sealed glass jar. You can check his videos, for more information. Or if you have his “Shop Tips” PDF, there is info there. If not, I can email it to you.

Thanks, Randy. I’ll see if she wants to give it a shot. Sounds promising.

Have use waterborne finishes on bowls not for food contact. Like oil finishes have to be flexible on drying times (re-coat, use, cured) based upon temperature and relative humidity. I buy locally so use brands available locally.

If could buy local would like to try GF Wood Turner’s finish. Lot of pen turners switching to this because sensitized to CA finish.

Thanks, Bill. I’ll keep an eye out to see if it ever goes on sale. I’ll have to order on line since there are no woodworking stores anywhere near me.

+1 for “O. B.’s Shine Juice”.

Another friction finish option is a mix of shellac (8 parts) and liquid carnauba (1 part). Where do you get ‘liquid carnauba’, you ask? In the automotive section at the big box … I am partial to Kit but other manufacturers have similar products.

Shellac runs about $12 a quart in the box stores around where I live … polyurethane finishes average about a dollar a quart more. IMHO, shellac is one of the best bargains for finishes you’ll find. Also, shellac can be be put under or over any other finish.

Going to big box, paint, or hardware stores locally should find finishing products you need. Nothing really special about finishing wood turnings.

When started turning pens, GF Enduro (floor poly) was the hot finish if wanted glass like finish. Went to Lowes and bought a can of Minwax Polycrylic.

I love shellac and buy it locally, Zinisser products have served me well. Before that could buy 3Lb cut of Minwax shellac. Lowes & Home Depot have stopped selling any brand of shellac here.

I love Deft brush on Lacquer, not sure will get some these days Lowes & Home Depot stopped selling it here.

Hope to find Zinisser & Deft at another store or will change brands.

Bowls listed on my project page finished with Deft or Rust-Oleum High Gloss. My picture taking skills leave a lot to be desired.

Do not rule out clear finish in a spray can. Do heed warnings & precautions on labels and spray out side if possible. Used that stuff from Walmart once or twice.

Thanks for the tip on the spray cans. I ruled them out, simply because I hate spray paint. The bullseye shellac is $13 or $14 per quart, which seems like a lot compared to a gallon of poly at $37 a gallon or spar urethane, which I’ve never used, at $30 a gallon. My go to finish has always been oil based poly, but recently tried BLO and Danish oil, both of which I liked. However, my wife likes a high gloss, so BLO or DO won’t do it (unless I am missing something).

I’m no expert….
Heck, I’m actually pretty clueless when it comes to finishes!

If you really like the BLO or Danish Oil….
you can do a coat or two, allow to cure/dry, then top coat with an appropriate high gloss.

What’s an appropriate high gloss finish, you ask….
I told you I was clueless, or don’t you remember!!! ;^)

After learning how shellac is made, I’m surprised how cheap it is.

Normally wood turnings do not take a lot of finish, so buying smaller quantities just makes sense. I like pint cans, but normally only find quart cans on the shelf. Might take me a year or three to go thru a gallon of finish. Would probably end up throwing most of it away.

I stopped buying Watco Tung Oil, (oil varnish blend) because of price & deterioration on the shelf. Have had better success with Formby’s Tung Oil, (wiping varnish) less than $10/bottle. Really doubt any Tung Oil in either product but they are easy to apply.

Wildwood is right … if you are buying finish by the gallon for turning projects you better be a production turner or you’re going to waste a whole lot of it.
