Wood Flour Filler

Wood has grain; woodfiller does not, so large areas of woodfiller look nothing like the wood that surrounds it. Even when it does take on the color of the stain or finish you use, it will still look like a big, undifferentiated blob on your floor. The great thing is that it is your choice and mine to work crappy wood, or not, and to use whatever filler we find to our liking, or none at all. If your filler is not properly matching the color of your wood floor, you can mix different colors together or add something else to affect the color. The gel work great on outside siding or jobs where you want a thick epoxy that won’t run under gravity. I then use regular 3M fiberglass resin, the type used with fiberglass cloth to patch wood and fiberglass boats, Corvettes, etc.

This filler is only used on floors that are already finished, and prefinished hardwood floors. Adhesive filler mixtures cure to a strong, hard-to-sand plastic useful in structural applications like bonding, filleting and hardware bonding. When using epoxy solvents, work outdoors in a well-ventilated area, or wear an OSHA-approved organic Vapor respirator with fresh cartridges. Hello Scott, I wonder if you have a recommendation for a wood filler that could fill gaps in a pre-finished wood floor. For a filler I use Evercoat Rage which is a step above Bondo for quality and durability.

So this is why I like to use West Systems epoxy, although I buy very large containers and I don’t believe HD sells it. So I think your best bet is to head to HD, and look for epoxy with the longest cure time they have. Bondo is a catalyzed polyester filler (costs about $40/gallon) that can be mixed to dry in minutes to really move a job along. Vacuum the dust from the repair and brush a coat of top-quality alkyd primer over the epoxy and surrounding bare wood. Oil-based Crayons and Colored Fillers – These nonhardening fillers are for tiny dings and nail holes. Also worth experimenting with using varnish as your binder for wood flour or sawdust in particular.

I used the epoxy on all four faces of six 6×6 posts to get more accurate results, rather than to just one or two 6x6s. Because of its strength and durability, it is as different from wood fillers as a permanent solution from temporary remedies. If a large hole goes all the way through the side of a bowl, I will often cut strips of wood to wedge into the hole to form a foundation for the epoxy. My home was built in 2003 and I have problems with my exterior wood trim (1X4’s)and fascia boards (2X10’s). I will be sanding it, if that matters, so it should be a sandable filler as well.

Getting the filler to go all the way black might be difficult but I would do some tests with filler and stain to see if you can get the color where you want it. If you are going to paint it black then the solution is a bit easier and I would use the LiquidWood and WoodEpox so you get a more resilient finish that bonds well. I had also mentioned that I was going to try an epoxy filler (similar to a Bondo-type product), that’s made by Evercoat. Wood deterioration caused by UV light is different in type and appearance from deterioration caused by rot fungi.


Keith you could remove the bondo (which I recommend anyway) and do a dutchman patch that matches the rough texture of the wood. I’ll need waterproof obviously, but also something that has some flex as the wood continues to shrink/expand. You could leave the epoxy clear, mix it with saw dust, mix it with powdered stone like turquoise, and so on. The process is more or less the same. Spackling paste is designated for interior use, exterior use, or interior/exterior use. The CPES™ will serve to fill and bond in the tiny spaces that exist between the wood fibers, restoring strength. Little or no epoxy sagging (use a lot less epoxy!), an epoxy surface as smooth as plastic!

Once it hardens, epoxy is easy to shape and sand with standard woodworking tools. The final appearance of the repair is easily attained because ConServ Epoxy 200 Patch/Filler can be shaped and finished to imitate the original wood element. In order to ensure adhesion of whatever primer or paint is to be applied next, it is recommended that Smith’s Fill-It epoxy filler be sanded before painting. Wood filler and water putty don’t fill the cracks all that well; they seem to have their own cracking problems and leave a texture that doesn’t match the original wood.

Apply unthickened epoxy to the damaged section, allowing a few minutes for it to soak in. Reapply epoxy as it’s absorbed. Holes spaced about 1 in. apart to allow epoxy consolidant to soak into any water-damaged wood surrounding the repair (see Photo 3). On vertical surfaces, slope the holes slightly downward to form pockets for the consolidant. For more advanced repairs, Bondo® Wood Filler can be applied in layers to rebuild rotted or missing pieces of wood. I have a couple of nice, old, solid wood doors from the 30s & while the paint is quite sound, there’s an unintended crackle effect.

When using this filler, it helps to carry small amounts of this filler around in a damp rag, the damp rag will keep the filler from drying out while using it. This stuff will dry in your hand and stick to your skin. Perhaps a lot of people get confused because they see that the Minwax wood filler is a two-part product, like epoxy, so they think it performs like epoxy – it does not. After removing the mold, sand the epoxy dull and apply quality latex or fast drying oil-based paint to protect the epoxy repair from sunlight. Lacquer based wood floor filler is a mixture of lacquer and very fine wood dust.

It consists of an epoxy resin and a curing agent which is derived from natural wood resins, and so is very compatible with wood. We need to fill all the little staple holes with a filler that will take the stain to the same degree as the natural wood so we don’t have a bunch of little spots that don’t match. NOTE: The above products of ConServ Epoxy LLC are recommended for treatment of thicker wood such as window sills.

This filler needs to be under a coating of something, if not it will dissolve and leave a latex haze when ever the floor is cleaned with water based cleaners. Polyester Wood Filler should be stored at a temperature less than 85 degrees F. Storage above 85 degrees F will shorten the shelf life and render the product unusable. Once you’ve thoroughly mixed the putty (see How To Mix Epoxy ), press it into the cracks and crevices along the upper surface and the edge of the base to seal it against leaking. Latex filler is water based, stainable similar to soft wood, easy to apply and sand.

Using a right angle grinder and then a sander I quickly (within about five minutes) removed excess epoxy and got down to a nicely faired surface. We put wax paper behind each area to be filled so that the epoxy filler wouldn’t bond to the board behind it. I have a flush plane I use to level the epoxy after a fill (within the first hour of pouring it). After the consolidant hardened, we used epoxy filler to reshape the missing parts of the siding.
