RE: tung-oil/polyurethane finishes

[dan2004]

Hello everyone,

Just wondering if anyone has used a tung-oil/polyurethane finish before. If so, what did you finish with it? How did you mix the tung-oil and polyurethane? Can it be bought already made? Any special techniques that you used?

Any info would be greatly appreciated.

Thanks all,

Dan, I've finished tables and lots of shelving with Tung Oil & polyurethane mixes. I've mixed my own (50/50), as well as buying some ready made (in Australia Feast Watson make a ready made mix called "Floor Seal" - used for flooring and furniture.) You can brush it on, but by far the best application method is spraying. Either way you need at least 2 coats, sanding back between coats with 320 grit orbital. You need about 12 hours between coats, depending on temperature. Overnight is best. The first coat is a sealing coat and feels a little "rough", especially if it raises some of the timber grain. You must sand back between coats. The second coat looks and feels great. Satin lustre, very hard and water / heat resistant.

Lighter coloured timber can get a yellowy tingue over time - more so if exposed to direct sunlight.

I recently used Minwax Wipe-On Poly, purchased from Bunnings. I believe it to be a poly/tung oil combination. It comes in two finishes, gloss and matt.

I applied with a cloth in the same way tung oil is applied. It is the easiest finish I've applied and dries hard and water resistant in a matter of minutes. Other that the Ubeaut finishes I use, it’s the best product I've used for obtaining a professional finish.
