antkn33 Posted November 3, 2016 Report Share Posted November 3, 2016 I applied two coats of teak oil to a project. I let the teak oil sink in for about 15 minutes then wiped the excess off each time. After letting the project dry for two days I noticed light colored patches in some places that are rougher than the rest of the piece. It almost looks like it has been sanded in these patches. I wiped the whole piece down with mineral spirits before applying the oil and didn't see any of these patches. It is difficult to see in these photos, but you maybe able to make out the lighter covered patches on the maple. I am wondering what might have caused them and how to get rid of them.

wdwerker Posted November 3, 2016 Report Share Posted November 3, 2016 Could be where a sweaty hand was on the bare wood before you oiled it. I have also seen sweat raise the grain and even after sanding the spot was visible, but only after the finish was applied. 2 Quote Link to comment Share on other sites More sharing options...
antkn33 Posted November 3, 2016 Author Report Share Posted November 3, 2016 Weird, never had that happen. So do you think sanding it and re-applying finish will get rid of it? Quote Link to comment Share on other sites More sharing options...
wdwerker Posted November 3, 2016 Report Share Posted November 3, 2016 That's what I would try in the least visible spot. Sand, wipe w mineral spirits or denatured alcohol , let it dry thoroughly and re oil feathering it out around the spot. Quote Link to comment Share on other sites More sharing options...
AceHoleInOne Posted November 4, 2016 Report Share Posted November 4, 2016 What that is, endgrain. Like the edge of a board. The teak oil was sucked in deeper. Simply sand those areas along the rise in the wood with a higher grit sandpaper to seal off the endgrain, thus slowing down the take up of finish. Your issue really began by wiping mineral spirits on the wood before applying the teak oil the mineral sprits soaked into the endgrain, prohibiting the take up of the oil. -Ace- 1 Quote Link to comment Share on other sites More sharing options...
gee-dub Posted November 4, 2016 Report Share Posted November 4, 2016 I'm with Ace on the higher grit technique. I use a lot of exposed end grain on certain styles and use this technique to control oil based finish absorption. The variance is greater on full end grain but, the method for controlling it is the same. I have tried pre-finishing anticipated areas in the past and found that higher grit sanding, or burnishing, provides me a more controllable result. 1 Quote Link to comment Share on other sites More sharing options...
antkn33 Posted November 4, 2016 Author Report Share Posted November 4, 2016 I guess the end grain came from the areas that were sculpted in a curve? I've never had end grain in the middle of a board! Quote Link to comment Share on other sites More sharing options...
