Our first choice for filling the pores of open-grain woods. Compatible with all stains and finishes.

The first step to a flawless professional finish!
ColorTone Waterbase Grain Filler is our first choice for filling and leveling the pores of open-grain woods, such as rosewood, ash, koa and mahogany, before spraying a finish. No shrinking or cracking; it dries faster than other types of fillers, and sands easily. Supplied in 4-ounce jars, ready to mix with water.

"It's grain filler, wood putty, crack filler, hole-filler and mistake-patcher, all rolled into one product. The colors are natural and realistic."
—Dan Erlewine

  • Waterbase, non-toxic, solvent-free and nonflammable
  • Compatible with all finishes, including nitrocellulose and waterbase lacquers
  • Compatible with most stains, waterbase pigments, sealers and topcoats
  • Traditional guitar colors
  • Neutral is a light base filler for custom tinting
  • Easy to apply, dries fast and sands easily
  • Fills wood pores without sinking, shrinking or cracking

ColorTone Grain Filler is supplied in paste form, ready to mix with water (10-15 percent water works well for us) and brush on the wood. Let it dry, sand the surface level, and clean with a damp cloth. It's that easy, and you're ready to spray a smooth, blemish-free professional finish. No shelf-life problems: if the filler dries hard in your cup, simply add more water.

Why use grain filler? Unfinished rosewood, mahogany, koa and ash have porous "open-grained" surfaces. Filling and leveling the pores leaves the surface smooth for applying uniform finish coats. Using a contrasting filler color can often enhance the grain as well.

Good for voodooing

By \N from \N

Mixing a bit of the Stewmac dyes with the neutral (white) paste works well on my latest batch of swamp ash. its water based and I found that sealing in between with rattlecan satin lacquer makes sanding w/out breakthrough much easier. Dye black, then seal, then grain fill, scuffit down and then seal again. One of the easiest finishes I've ever done! I also did a couple strats, one red and one blue .

Grey is the new black.

Good product with limitations. The smallest amount of moisture will remove the filler in a blink of an eye. So try not to use a damp cloth when you clean up. When you use brushing varnish you will always remove a little bit of the filler.
My main problem is that the black filler is not black at all, but dark grey, and not even a very dark grey (in wet condition of course). My mahogany guitar with grey pores looks rather strange.

Easy to use

I've used solvent and water based fillers, this one is my favorite. The cleanup is easy and if you wait a bit too long to scrape (it dries quickly) a damp cloth does a great job of removing any residue. It does a great one-application fill on Mahogany.

Another great product offered by Stewmac. Works well for the guitar builders needs.

great product

I had 2 projects involving mahogany-a solid body guitar, and a mandolin "kit". both had nice wood, but pore depths were daunting to say the least. the filler, properly mixed did an outstanding job of filling out the pores in the wood, sanded very easily to give a nice level finish, and accepted the chosen stain virtually identically to the surrounding wood.
I easily give this product 5 stars.

Great Product

Stuff takes some getting used to but works excellent. Filled my African mahogany JEM 7 perfectly. The grain was near undetectable and although we are painting it the grain had an enhanced look after application of the sanding sealer. would use again.

Works great.

This stuff is very concentrated and just a little bit goes a very long way. I just love it.

Work's great!

This stuff does the job, I had a few grooves in the fingerboard from the file grazing it, No problem though. Seems to leave barely noticeable lines. Other then that VERY HAPPY WITH IT!!

beautifully enhances the grain

By Samuel Kaivola from Vreta, Finland

Fills the pores well and makes the grain stand out. I used medium brown rosewood on my first build and it worked very well. And as said let it dry a bit longer than the instructions say before you add anything on top of it.

Not for me.

This product may work for others but it did not for me. I can understand that there is work involved using this wood filler but I could not make it work for me. I tried three times and the grain would not fill. I did find another product that I am using and I have to admit that it is doing the job. As for the other products from this company I will give them five stars.
