Topic tags/keywords: question lathe finishing

I’m beginning a project to turn a vase (after my son finally falls asleep) for someone but was just curious if anyone has done this type of thing with the intention of actually using water in it and cut flowers. My normal goto finish is De-waxed shellac (which I plan to use on the outside) but would something like tung oil or even poly work to coat the inside to give it the best water resistance?

It’s not going to always be holding water but will on special occasions, otherwise it’s just going to sit as decoration.

Any thoughts?

Thanks.

I’ve heard of people using General Finishes High Performance in high moisture environments. In fact that’s what the manufacturer says it’s for. But as for complete waterproofing – and using a turned piece as a vase I have no direct information. You’re in a risky spot. It’s going to be next to impossible to detect if you missed any spots in terms of coverage. If that happens – then your piece will be damaged.

I would go a different route and actually turn it to ‘accept’ a glass vase. But that’s just me!

Another thought just popped into my head – Waterlox makes a Marine grade finish. No experience with it though.

I guess you can still get the 2 part resin coatings they used on decoupage way back there. I made some large lap desks once for college students and used that to finish them. I had seen it on some tables in a restaurant. This stuff is near bullet proof and I am sure it has to be water proof. I will say it has a pot life (20 minutes I think) and you should not try to get close to that. Mix it up, put it on, and heat it to make it flow. Also it has a chemical reaction and gets hot. Really hot to touch so don’t try to hold it in a bowl or tub that is thin because when it reaches this 20 minute limit it will burn you. I think I paid $20 about 20 years ago for about a pint of this stuff. No other ideas.

Just remember one thing, every watch company out there will say that their watches are water RESISTANT, not water proof.

For a turned piece you are defiantly going to need a two parts resin like the ones that restaurant bars are covered with.

I would experiment with a piece that doesn’t mean a lot to you first before I used an important piece you want to keep.

for sure! for sure!!
You will also need to think about how you will get it in the vase. Heat makes it flow smooth. You can even use a torch or an electric blow gun was what I used. Mostly to remove bubbles.

Just a thought… Use CA poured into the vase and swished or turned until it is completely coated, pout out excess and let completely dry. Then use a bar coat two part resin. You will have sealed the wood twice.

Thanks for the thoughts and ideas everyone. Guess I didn’t think of using CA and resin, or just turning it and putting a glass vase inside.

Much appreciated.

I had another thought but I actually know nothing about the product. People that restore ventage automobiles, motorcycles etc us a product to salvage those old gas tanks. They pour it in and rold it slowly over and over to coat the inside of the tank. That is supposed to seal all the rust and I think it will close up small leaks. Check into that product also and see what it does and if it will work on wood.

Have your say...
