i’m was wondering is someone can tell me which wood is the most porous wood.
i need it to be porous so when i dip it in paint, the paint will actually be sucked into the wood, so when i sow it, the paint will be already inside the wood.

Sow it? I dont follow your meaning.

Oak is very porous, but you would probably want to use a vacuum chamber if you want the paint to soak up into the wood.

And you would want to thin the paint probably.

Yeah I’m thinking you’ll need a vacuum chamber and thinning too, depending on how far in the wood you want it. But the wood database ( describes a few species as being especially porous, balsa, paulownia, and catalpa.

I assume you meant “so when I saw it”. If that is the case, I agree that that the paint will need to be thinned. Then varying the length of test pieces, use a shop a shop vacuum on the opposite end of the wood to suck the paint up into the wood to see how far the paint penetrates. The wood will need to be straight grained for best results.

I’m curious about your application and would like to see pix when completed. :)

Paint particles are way to thick to sink much into a piece of wood, even when thinned out a lot. I suggest you dye it with a water based aniline dye and let it sit immersed in the dye for several days to get penetration.

If you go with oak, it needs to be red oak not white. White oak has closed cells which would make it resist the vacuum trick. Red oak has open cells and would absorb some under vacuum.

Have your say...
