Topic tags/keywords: question walnut finishing

Hey LJ’s,

I have a gallon of mineral spirits based walnut stain that I want to use up. I would like to even out the color on the different walnut boards I have , including my chainsaw milled pieces.

This is my first time working with finishing walnut and I’m looking for some advice to keep Murphy at Bay.

I usually use a non waxed shellac sealer on softer and porous woods like fir, pine etc. Should I be using the same steps for this situation.

Thanks for your input!

I use a lot of walnut and have never experienced blotching.

Nope. Walnut should not blotch when applying an oil based stain.

Hi Tom
If your trying to stop blotch then I agree with the rest of the comments,but if you are trying to match color then
Charles uses dye/stain thinned down to make sap wood match the rest of the walnut by adding additional coats until it matches.

Hey Jim!,

I have Charles’ finishing DVD’s . Not sure if I want to dye the white sap wood. More interested in evening or enhancing the existing wood. Does the dye blot out some of the subtlties in the wood? ( am I too lazy? )

You should be safe by adding on additional coats of walnut stain without any problems. Be aware, I was doing something similar to what you are trying to do and some of the walnut stain was starting to look almost black.

I haven’t had problems with blotching on walnut. I am also a big believer in sample boards!

Hey Charlie,

Sample board good. LOL! Just have to see what I have to use. Did that once and sample board didn’t match the piece.

Dave,

Were you using a mineral based stain?

Thanks for your comment.

Ahh, even with the best laid plans…

But seriously, I do make sample boards. In fact, I tend to go overboard. Just saying. LOL!

Charlie, the walnut will have smooth and undulating surfaces. Will keep the sample boards in mind when doing this.

Tom, I was using a miniwax walnut stain with a mineral spirit base. I had this qt can over 20 years now and it works well. I was trying to stain some of the sap wood to match with the heartwood. It turned out somewhat decent, but if I got a lot of the stain on the heartwood it would turn almost black. Maybe its the stain itself, can’t say for sure. I just had to be careful.

Dave,

Thanks!

Not going to get too involved as I am ok with sapwood, but as Jim said Charles has done a great job on explaining the use of oil vs waterborne and dyes. Just requires time. :<)

One other bit of advice speaking from experience this week with walnut is to to fill the porous holes with a clear wood filler. Fellow LJ’er Ron Ford gave me a small sampling of a product called Aqua Coat. I was finishing some walnut, sanding it to 400 grit, used mineral spirits to clean out the pores and started to finish it. After the first couple of coats of a water based poly I sanded it down for the final coats and the pores accumulated some of the dust from sanding smooth the poly making them appear very light colored and noticeable against the darker walnut wood. Using mineral spirits to clean them out didn’t work well and ruined the finish that I had started to build up.

So I sanded everything back down to the wood, used the 2 applications of the Aqua coat and all was good. You apply it like a car wax is circular motions to fill in the pores thoroughly then sand it down smooth to the wood so only the pores contain the actual clear filler. I am very pleased with the result. Not necessarily commenting on the stain of your original post, but if finishing walnut those pores should be filled in with a clear filler to make your finishing process go well.

Tom, I’m on the same page as others, I’ve worked with both American and Peruvian walnut, never encountered any issues.

As for as the wood it’s self goes, the Peruvian walnut is a much more softer and dense wood than our american walnut is but cost wise it’s much cheaper at the lumber yard than our american is hence the reason I buy it over our american walnut plus it gives a much darker rich brown.
