I have tried different ways at grain filling without a lot of good luck.On another web site someone said to use epoxy,apply a thin coat and let dry.Then sand off to the wood surface,and the open grain(walnut,mahogany)
should stay filled in.Anybody have any experience with this?Will this technique also work for marquetry?Would like to hear from other woodworkers their experience with grain filling.

rklong,

I have used the epoxy filling technique for years with great success. Sanding it back down so its only in the grain is a bit of work but does the job quite nicely.

Sincerely

Hi Darryl, My experience with epoxy is that it tends to shrink a lot over time as it cures. I recently made an epoxy glassed hydroplane boat. After several months the screw holes which were filled with epoxy as a filler all started to become depressions because the epoxy shrank. Also the fiberglass mesh which reenforced the epoxy clear coat also started to show through badly. It was a system 3 product. A professional wood boat builder told me it was because expoxy shrinks badly. Is this a problem when you use epoxy as a grain filler. I always use multiple coats of shellace cut back as a grain filler, but I have the same problem with shrinkage after a while. I have never found a good grain filler. Scott

Scott,

I've never had a problem with the epoxy filler method. Some of the pieces I've done it on are over 15 years old and doing just fine.I think its a lot different glassing a boat.

Epoxy as a grain filler is just saturating the fibers and filling the open pours. Its really a very minimal coat, and then you sand it back down to bare wood as well.

Sincerely
Darryl Keil.

Luthier mercantile sells an epoxy specifically for use as a grain filler(http://www.lmii.com/). Typically guitar makers are fanatics about perfect finishes and are very knowledgeable on finishing.
Super glue applied with a paper towel works well and is fast.

Russ,

You've got to explain this one. Super glue applied with a paper towel sounds like a total disaster! I have never heard of this. How do you do it?

Sincerely

super glue filler:
1. Use a medium super glue
2. Pour a small amount on an unprinted paper towel
3. Lightly rub on prepped surface to fill pores
4. Let dry, sand and repeat until pores are filled, don't leave a thick coat on the wood-just fill the pores and depressions
5. I then spray 2 coats of dewaxed shellac and muliple coats of nitro lacquer.
6. Gives a flat surface in less time than using lacquer only.
7. Is very clear (water white), doesn't obscure the grain, isn't muddy
8. Faster than epoxy
