Hi,
I need help. One day after staining (Minwax) a quartersawn white oak table top, I noticed a few small gouges in the top, which made for some darker blotches in an otherwise beautiful surface. I sanded through the finish, and reapplied the stain, only to see a noticable difference between the areas that had been sanded versus those that were left alone. Since it is the exact same batch of stain, and the wood had not been stained before, I am at a loss. Suggestions will be greatly appreciated! I’m hoping to move to the topcoat stage soon, if I can get this figured out.
Thanks,
Two Sheds

I'm a little unclear about what was sanded out and what was not. Is this a new table you made or are you refinishing just the top? Did you resand the entire surface? If you only resanded the spots, the wood is going to take the stain at a different volume than the surrounding area since the surrounding area is already sealed thus coloring it differently. If you indeed did resand the entire surface and the wood was all fresh and the stain was all the same, perhaps it wasn't sanded to the same surface grit as the rest, that's important. If you only sanded the spots, I suggest carefully coloring it in with an artists brush and blending in the outer areas of the spot. Surely there are past articles in FWW about doing this. Most any book on furniture repair will go through these steps.
Hi Jer,
Thanks for the reply. It is a new table, although it has been stored for over a year unfinished. I sanded the entire top with 120 grit- the same that I used on the spots, before staining. I checked again this morning, and still see differences in appearance of those areas that I sanded and repaired from some angles. From straight down, the color of the repaired areas blends into the rest just fine.
I am planning on using satin wipe-on poly as a topcoat. Is there a chance that the solvent in the poly will cause some of this to blend together?
I'll also check in any books I have, but haven't seen this particular description yet.
Thanks,

I rarely use Minwax stains cause they have sealers that make 2nd coats impossible.

Where did you hear that?..They (Minwax) recommend 2 coats. Please do not mislead the guy.
It also says "Do not sand between coats of stain".
That's one reason why I don't like the stuff. I had so many bad experiences with Minwax that I quit buying it years ago. Plenty of better alternatives out there, in my opinion (obviously).
My favorite stains are the Old Masters brands. They penetrate well and don't contain sealers.

Try wet sanding a second coat of stain on the whole top with 320 or 400 grit. It'll even even-out lap marks.John O'Connell - JKO Handcrafted Woodworking

I'm not sure if I can make it clearer but here goes. A trick I've picked up to even out and accenuate the grain in open grain woods without over-darkening the whole piece is wet sanding. What's happening with this piece is that the oil carrier has penetrated the wood and sealed it beyond the depth of the sanding. The pigment lays on top and is easily sanded off. By lubricating 320 or 400 with more stain the harder wood is stained but a much of the larger pigment particals are abraded off while the resulting stain/oil slurry tends to fill the the open grain. The result is that the figure is highlighted while the harder wood is evened out. If there's a lot of flake it will really bring it out. You really have nothing to loose, if you don't like the effect you're right back where you are now - deeper sanding.John O'Connell - JKO Handcrafted Woodworking

John - I understand that, but what's that got to do with MinWax stains??

It sounded like the problem was a combination of sanding out the the gouges and oil based stain in general, not necessarily just Minwax stain. The only thing I've found that's harder to do touch-ups with than oil based stain is Woodkote gel stain. My thought that wet sanding with stain might blend the repairs without having to sand the whole top down to virgin wood. John O'Connell - JKO Handcrafted Woodworking

Oil finishes don't redissolve once they're set up. Which is to say that it's not soluable once it's dry. That's why sanding thru in spots doesn't blend back in when you reapply the oil. I would suggest completely stripping the whole surface where the problem areas are in. In other words... if it's just on the top that you're having the problem with and the edges/sides are fine... just strip the top and reapply the oil to the entire top. There would still be a slight difference between the reoiled surface and the other existing oiled surfaces. But, the naked eye won't be able to spot it. You can see the difference right now because there's no obvious break to distract the eye.
In my experience, even with soluable finishes it is frequently better to strip and restain an entire surface because it can be difficult to get even a soluable stain to blend in right when just doing spot repairs.

Wipe it down with mineral spirits. Get as much as you can off, rub it dry, then re-apply a coat of stain following the directions. I always use mineral spirits to even out oil stains.
What he said. No problem.
