Fill It Up
I have used other type and brand wood filler. None is as good as Wunderfil. I have used it for over 20 years.

This is, by far, the best woodgrain filler I have ever used. It is inexpensive, water thinable, and leaves a mirror finish on oak.

This is the best wood filler I've ever used. It dries quickly, has low shrinkage, sands smooth and takes a finish so well you won't know it's there. I tried some other brands to avoid shipping after I moved, but nothing compares.

I need a water based grain filler for a small oak table top. My old filler dried out in the can.
Wanted to try this. it's a smaller size container; less chance of waste an drying out.

i have used it before and it worked great. Matches and stains well, sands easy.

David W on May 2, 2016
I have lots of cherry wood that I milled myself. It is not perfect, so I need some filler that matches the color. The current filler I am using doesn't do a great match and I touch it up with stain. I hope this solves the problem.
Charles R on Apr 7, 2016
It is a great filler that does not stain the wood area around where you are filling, is easily sanded, takes stain well, and is easy to sue.

No other wood filler works like Wunderfil. I have tried several others that were recommended, but always come back to and prefer Wunderfil.

Marvin S on May 31, 2018
If you use Wonderfil on raw wood then go over it with a water-based dye stain like GF’s, will the Wonderfil dissolve or pull up?
Monday317 on Aug 8, 2018
BEST ANSWER: I often use a wet rag or sponge to remove excess wonderfil after it has dried, I'd think that it would loosen up if you rub too long or hard. If you just allow the dye to soak in and dry, it should be fine.
Will Wunder-fil hold a screw?
Frank G on Jul 6, 2015
BEST ANSWER: This is only for filling holes.
I would recommend that you fill the hole with a piece of dowel and then re drill it.
Can dye be added to add contrast to grain, while filling pores?
Monday317 on Jul 26, 2017
BEST ANSWER: Work with just amount you need so as not to mess up the whole jar. . . I have added color to the wood fill. . . Iv'e used sawdust and I've also used a little paint to change up the color. Can't use much, in the form of liquid..
I am painting oak veneer hollow core doors and is like to fill the grainy pores. Will this work as far as adhesion?: clean, scuff sand varnished surface, tack off, skim thinned wunderfil, sand smooth, prime with a latex primer, sand smooth, maybe 1 more coat primer, sand, paint with latex paint.

My concern is the wunderfil going on first on the scuff sanded varnish. Or should something be put on first to ensure adhesion?
LisaB B on Jun 5, 2017
BEST ANSWER: I would recommend first using a palm sander to go over the entire door. Use a 200 grit, or higher, sanding disc to avoid burning through the veneer. Then I would apply an oil based primer, such as Zinzer 123. Latex will not adhere to varnish. Apply the primer with a foam roller to get a smooth even layer. Check for remaining grain after the primer dries and sand lightly as necessary by hand using a sanding block and a fine grit sand paper. You can fill minor imperfections with the Wunderfill, but filling the entire door would likely be impractical, as the filler dries quickly and you can only work small areas at a time...and it will likely not adhere well directly to varnish. You should be able to hide the grain with several coats of primer, rolled not brushed, and sanded between coats. You can then apply your latex finish coat over the Zinzer 123. As always, refer to the manufacture's directions on the label for best results. Good luck with your project!
I love this product but over time it dries out and get really hard in the jar. Is there a way to prolong the product? Is there a way to rejuvenate the hardened filler?
Jack H on Sep 5, 2017
BEST ANSWER: I’ve had this problem and I just put small amount of water and reconstitute it with a slot screwdriver. Works fine
We are painting the cabinets in our kitchen and I bought this product to fill the grains in the oak of our drawer fronts. After applying 2 coats and believing the the process was complete I have painted the fronts, sprayed with primer and 2 coats of oil-based paint - but there is still pitting (I assume from not completely filling all grains. Can I lightly sand/scuff the oil-based paint and repeat the filling process, or do I need to completely remove the paint and start over? Thank you.
Jake D on Apr 19, 2017
BEST ANSWER: It should work, but sand pretty heavily.
I want to fill the grain in some white oak countertops and then stain them before applying the finish. I am using Kona stain (dark brown). Will the filler stain like the wood or will it show up when stained?
brian on Oct 12, 2016
BEST ANSWER: Typically from my 20+ yr experience, finishing can be very finicky, I usually choose stains and filler from the same maker. However, if you don't leave any residue on the surface, it should stain and finish pretty well were you won't notice the filler at all. But the best method it to sample it. Take a piece of the oak, do the entire process, and see for your self.
I am using to fill grain in oak cabinets before painting. What is the best way to clean after sanding before coating with sealer? Tack cloth? Afraid to use damp cloth as it seems to dissolve the product.
designer deb on Sep 12, 2016
BEST ANSWER: Use a tack cloth
where is the "black ebony" filler? Didn't you have this at one time?
