Wood filler
Absolutely the BEST wood filler/grain filler I have ever used. Sands superbly, takes stain and clear coat well. I will not use another brand again.

good stuff
it is the easy way to fill nail holes, cracks and any bad places on your lumber. and it dries well for sanding.

I have enough to last for years, just hope it does not dry out
in the container.

Great Product
If you want to mix your own filler, be my guest. If you don't, this is the product for you. Just open the container, fill the unwanted and create a new floor. Don't get any easier!

Wunderfil Wood Grain Filler is a super product.
I have been using Wunderfil Wood Grain Filler for over ten years, especially on oak, but it works equally well on every wood species I have tried it on, it takes both pigment and dye stains perfectly, and products the most beautiful finish on any wood. It makes me look like I am a gifted woodworker. I believe any one trying this product will be very happy with the results.

A really fine filler
I work mostly with oak and use this exclusively for filling holes and grain. It is the best product that I have found for these purposes. It takes stain really well as well as oils and shellac. It makes my projects look really sweet.

I built all new oak raised panel doors for my kitchen and used it exclusively on the doors & cabinets. It is very easy to work with, accepts stain great and sand very smooth. It can also be thinned and apply over the entire surface then sanded down for a glass smoothness. Just make sure you tighten it complete for storage and it will last quite a while no dry up. It is the only filler I will use now. It was recommended to me by a far superior cabinet maker than myself.

Good shtuff!
I bought a couple of quarts and put it in empty caulking tubes that I got from Amazon. It's the only way to go if you have a large project like chinking gaps in boards. A good variety of colors too.

have used in the past as pore filler and it works well, thinning it is tedious but worth it

I've used this product before and unlike other brands it doesn't dry out in the container over time. It spreads well and fills nail holes or voids in wood fairly well.

I have used this product many times and it performs perfectly, it fills the grain in open pored woods, sands easily, stains perfectly, and takes every finish product I have tried beautifully. It makes me look like I am a talented woodworker.

Can Wunderfil Wood be stained with an oil based stain after it is dried and lightly sanded?
Willard on Aug 12, 2015
BEST ANSWER: I have used the Wunderfil grain filler products with oil based stains for at least ten years now, it works perfect with oil based stains.
I applied thick paste initially on the back of cabinet doors. Do I sand all the way so I can see the grains again? Or would the shellac-based primer take care of that? Do I even need a shellac-based primer after wunderfil? Thanks.
Rissa H on Apr 24, 2018
BEST ANSWER: Y0u definitely have to sand .
What is the best way to apply this filler to red oak table legs? On or off the lathe? ... and how?
TimBo266 on Jun 29, 2016
BEST ANSWER: I have found that I can apply the Wunderfil grain filler by hand, it applies very well this method to turned pieces, either in the lath, or out; after drying, just lightly sand it with a fine grit paper, and you will have a beautiful surface.
