Thread: Waterproofing my D.R. Harris/GFT/T&H wooden bowls

Wanting to waterproof both the wood and the stickers and paper ribbons (DR Harris bowls) using an oil-based clear gloss polyurethane spray. Would one coat be enough or would two coats be better?

I would do two to three coats.
Bare in ming the coats do not bind to each other and become one,so multilayer will last longer.

What do you mean? I'm confused, lol.

Oh I see what you are saying!

Polyurethane does not melt the previous layer to become one thicker layer each time it is applied.
Some finishes do. Laquer and Shellac actually melt the previous layer to become one thicker covering.
Polyurethane is very durable though, more so than the other two.

I applied 2-3 coats (3 coats on my DR Harris bowls). Really glad I did as the 3 coats really brought out the color and grain of the wood of the D.R. Harris bowls and sealed in the stickers and paper ribbons. I'm happy with the result. Now I need to figure out if I need to sand the inside of the bowls before applying the tung oil?

Applied the tung oil without sanding and then applied a beeswax/oil mix wax paste for an added priotective barrier against moisture.
