wet sanding tung oil?

[arjepsen]

Ok, I'm trying to get this swamp ash grain filled... got some Behlen water based grain filler, and tested it out on some ash boards I had.
Sadly, I didn't really like the look of it. I'd thought that the grain filler would be almost invisible, but it gives quite visible white lines where it fills the grain  :sad1:

I read some post with someone suggesting another method of filling, but wet sanding with danish oil.
I wanted to use Tung oil, so I'm wondering if there would be anything problematic in using that to wet sand - and thus fill the grain??
(sand to 220 - wet sand with 50/50 tung oil / mineral spirits)
I've tested it a bit on the ash boards, and it seems to fill the grain... but I'm not sure how long it will take to dry...?
I've waited for about 1½ week now, and tried sanding it back to 320... but the sand paper was clogged up pretty quickly - so I had to use quite a lot...(actually went back to 120 then 220 then 320). Also, I'm not sure if it's actually dry (that might explain the clogging)... even though I had it on the heater for those 1½ week.

Any comments?

You may have gotten the wrong color grain filler?

 

[arjepsen]

there were only 3 choices to go by (clear, brown and mahogany).
I think between these, the clear that I got is closest in color... but again, it still shows quite visibly.

Anyways, any comment on using tung oil as filler by wet sanding?
Will it give any trouble with drying/curing?

Sounds like you got "clear" which is really a "natural" for light woods.

Just dye what you've got, then try it again.  A water based dye/stain should do ok.

Hint:  Don't dye the whole can, just a little to use.  If you need another color for a different project later, you're all set to dye the remainder.
