Wood Filler Basics

It’s almost been 2 weeks since I posted about the stair makeover , but don’t think I haven’t been hard at work. It is primarily used to fill small holes and voids up to ¾ inches on drywall and plaster. Just remember to plug the holes since they will attract more carpenter bees come spring. 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. For example, if you have a ¾” board that the screws go into and you can’t use a longer screw because it will stick out the other side of the board. It’s always a bit of an artist’s touch to fill and hide damage in varnished wood.

You can completely hide holes and other damage using filling products, which is great news if a beloved piece of furniture, expensive wooden floor or exterior wood needs some TLC to bring it back to vibrant life. Like polyester auto body filler, it comes in two parts: a can of putty and a tube of hardener. Fiberglass laminate is hard and strong and using 404 or 406 Filler creates a hard, strong epoxy filler, which more closely matches the characteristics of the laminate.

If you’re filling an already finished floor or a prefinished floor with this product always, wipe the filler and area off with a damp rag or a shinny spot will appear around the spots that were filled. While the listing agencies and manufacturers seemed open to the use of automotive body filler (Bondo) for filling small blemishes in hollow metal doors and frames, they confirmed that it was not acceptable for filling holes. The easiest way to repair large holes is with a veneer punch also known as a veneer patcher.

Sistering” the beams with new, through-bolted wood is sometimes also a satisfactory solution. Now the wood filled portions have taken the stain a bit better and those parts are much less noticeable. If epoxy has leaked onto your workbench, denatured alcohol is the best solution. Thanks for your execellent article.I had two querries.I bought a second hand sheesham wood table which has a slight but long gap between the filler can I use. After paint-grade trim is nailed in place, the nail holes and gaps need to be filled.

The painter used at least 10 gallons of auto bondo (Evercoat White Star and Evercoat Lite-Weight) on the house. Because lightweight spackle has the ability to limit shrinkage, it will outperform traditional spackle for holes deeper than ¼ inch. TIP: See the differences (including pictures) between sandable wood putty and soft, oil-based putty. You can see in the photo above the slightly yellow spot around the caramel apple stick; that is just slightly wet wood from where I wiped away the extra glue.

On unpainted surfaces, finish putty can be made by adding sawdust to a mix of the L&L Resin until a spreadable consistency is reached. I think it’s also helpful to put painter’s tape on the other side of a hardware hole you’re filling to prevent the filler from going all the way through and leaving you a mess or a big bump to sand down. To make a thinner filling material that’s easier to apply, first mix a small amount of consolidant.

The absolute best for staying bonded to the wood is the Abatron products though. Scott…We have removed the fabric from the legs of our dining room chairs to stain the wood. Try an epoxy like WoodEpox or Minwax Hohh Performance Wood Filler to fill the gaps. You can find WoodEpox in my Amazon store Patching PT wood is always questionable depending on how dry it is and how much and what chemicals were used for the treatment.


It will cling onto the edge tenaciously and not chip off like ordinary wood filler which works best to fill a hole mostly. Continuing with the staining, I applied it to the remainder of the tread in the same direction as the wood grain. But this would be cheaper for a project like yours, and probaly more effective when the nail holes are so big (most of the ones in the floor are pretty small)! I’ll give it a try with stainable wood filler in an inconspicuous spot and let you know how it comes out.

Fillers can also be made of synthetic materials that will often accept wood finishing products. The first thing that came to my mind was wood putty, but I have to admit… I wasn’t sure if there was something better” that log home owners (or builders) themselves might recommend. Minwax Preparation products are the first step to ensure your wood surfaces show their most beautiful colours and smoothest finishes.

Mix sawdust and a carpenters glue or Elmers yellow or white glue ,go really heavy on the sawdust not to much at a time, it sets pretty fast put it in the nail hole or crack leave it sticking up a little above the surface let dry it doesn’t take but a few minutes to set up. Sand smooth. At the right we have a picture of a severely damaged column after the rotten wood has been removed.

The second problem we had was that the layer of paint meant to protect the wood was chipped and cracked, allowing water to soak in and rot the wood. It’s important to note, however, that wood filler is intended strictly for superficial issues, such as scratches and gouges. Other insects such as a variety of ants, beetles and bees often simply use the wood for home and breeding space. Bob Flexner’s Understanding Wood Finishing , for example, contains a thorough discussion of various grain filling techniques that can help you choose the best method, and apply it successfully on your first try.

Hi Scott, help….we have made an indoor cedar sliding barn door and have four screw holes that we have to repair & fill. Vacuum the dust from the repair and brush a coat of top-quality alkyd primer over the epoxy and surrounding bare wood. Before proceeding with nail putty, have a look here It has always been my recommendation to re-prime MDF when using putty, but again, you may want to sample your primer with the putty you choose before filling an entire house. So next time you use reclaimed wood, your project won’t be ruined by nasty nail holes before you even start! Once the glue is dry you’ll be able to sink a screw into the same spot and the screw will grab the wood of the toothpicks with no trouble!

To choose the right size drill bit hold the screw up to the light and then place the drill bits over the screw (lengthwise) – when you can still see the threads on the screw and the drill bit is covering the rest of the screws area, you have a pretty good fit – the threads need to ‘bite’ into the wood in order for it to hold. To make sure the new tacks will hold properly, I’ll fill the holes with a homemade wood putty mixed from sawdust and glue. Carol, I haven’t used the 2-part wood weld but have used the steel version of the same.

Wood filler shrinks slightly as it dries, so press it in tightly and leave it mounded slightly above the surface of the wood. I have an old door and am having difficulty screwing in the deadlatch to the door because of decayed wood. You could try using the bag to fill the holes slightly proud, then use a sharp chisel to remove the proud bits when they are partly set but still green. This is particularly important if you are going through the Fill-It™ Epoxy Filler.

I only filled about a quarter of the holes last weekend and I used a tongue depressor to apply the filler. Epoxy wood filler consists of two components, parts A and B. The two parts must be thoroughly mixed together so that the fill paste can properly harden. After several days you are free to come back with our Fill-It Epoxy Filler and fill all voids. They are a high-strength no-shrink adhesive paste to fill, repair and replace wood and other materials in structures, walls, floors, furniture, sculptures. The dried material is firmly bonded and holds screws as well as the original wood.

Thought I could just go to Home Depot and get some wood putty to fill in on top of the nails but saw so many different products that I decided to do a little research online and thankfully found your site. It takes stain decently but I would use some the Abatron powder tints to get the WoodEpox as close to the color of your wood as you can before staining. That depends on whether or not, as part of the refinishing process, you are planning to sand the floor down to bare wood. Either the Fill-It Epoxy Filler or the Layup & Laminating Resin can be pumped into voids with our Re-Usable Caulking Tubes.
