Is the wood around your home’s window frames water damaged and rotted? Is there a gouge or nick in your handsome hardwood floor? Scratched furniture, rotted wood trim, and chipped flooring are common household problems that can be time-consuming and costly to repair. Not to worry: if you are a handy do-it-yourself homeowner, you can use wood filler to repair dents, divots, voids, and blemishes quickly and affordably.
If you have not used this helpful product before, we think you will love it. Wood filler, also commonly known as plastic wood, wood jam, and grain filler, in a spreadable compound, filler, or grout used to fill imperfections in wood before finishing. Cabinet makers and expert woodworkers use wood filler to fill nail holes and open cracks in wood joints that require filling before finishing. Wood filler can be sanded, stained, or sealed to make wood flaws virtually invisible.
While you can fill holes, nicks, gaps, and scratches with wood filler or wood putty, the two products, although similar, have significant differences. Read on to learn about how to use wood filler and its diverse array of applications. When you are ready to make a purchase, consider our recommendations.
When shopping for wood filler, you will find several types. Some are formulated for general application; others are more specific. The type of wood filler you choose depends largely on the job.
Water-based wood fillers
Water-based wood fillers, also known as latex wood fillers, are specifically formulated for use indoors. They absorb stain similar to soft woods such as pine, and they resist shrinking and cracking. The product is inexpensive, easy to apply, and easy to sand.
Household applications include repairing cabinetry, wooden doors, trim, and paneling before staining and sealing. Water-based wood fillers are also useful when it comes to repairing surface damage to wood furniture and in filling imperfections on wooden household items such as photo frames, memory boxes, toys, shop art, and craft projects.
Solvent-based wood fillers
Formulated for outdoor use, solvent-based wood fillers (also known as petroleum-based wood fillers) are used for filling and repairing wood exposed to the elements: decks, siding, molding, and so on. Made from wood waste (wood scraps, sawdust, and wood dust) suspended in a petroleum-based glue-like resin binder, solvent-based wood filler dries rock hard.
Stainable wood fillers
As the name implies, this type of filler is receptive to staining. You can easily match the exact shade of the wood you are repairing with a stainable wood filler.
Prefinished wood floor filler
Prefinished wood floor filler is a product fairly new to the market. It is an excellent choice if you want to make minor DIY repairs to costly hardwood flooring. Damage from moving furniture, nail holes, and cracks disappear with a careful application of this easy-to-apply product. The filler is designed for use on floors that are already installed and finished and well as prefinished hardwood floors.
Prefinished wood filler compares to latex wood filler, except a polyurethane is used in the manufacturing process instead of water. It becomes waterproof after it dries. Therefore, it does not need a topcoat. The drawbacks to using prefinished wood filler are that it dries out quickly after the jar is opened, it becomes ruined if the product is allowed to freeze, and it is rather expensive.
Two-part epoxy wood fillers
Epoxy wood fillers, widely used in architectural conservation and restoration, can be a cost-effective and labor-saving way to repair wood flaws due to weather-related or pest-related damage. Areas that are difficult to replace, such as porch columns and brightwork, can also benefit from epoxy wood filler repairs.
Select an epoxy wood filler when the element cannot be easily repaired or replaced without taking apart other components. Pegged window sills and dove-tailed drawers are examples of home features where epoxy wood filler excels.
Wood filler has two primary purposes: to fill voids such as holes and dents and to fill pores and achieve a smooth finish when working with open-grained hardwoods such as mahogany, oak, walnut, and ash. The consistency of a product designed to fill large voids may not work well for filling small dents and porous grained wood. The reason: the wood particles used in the manufacture of the product may be too large to work into small nail holes and miniscule wood grain openings.
Apply wood filler with a small, flexible putty knife. Begin at the edge of the damaged area, pressing the filler into the void. Overfill slightly to make an allowance for shrinkage. Then, sand and finish the project. Small repairs are ready for sanding within 20 minutes. Deep or large repairs or patches may require up to eight hours to dry. Sand lightly to achieve the desired smoothness, stain, and finish.
When applying latex or oil-based wood filler, always follow the manufacturer's application instructions carefully to achieve the best results.
While most folks, when talking about household tasks, use the terms “wood filler” and “wood putty” as one and the same. However, expert woodworkers note that there are important differences between the two products. Once applied, wood filler dries to a hard, dense consistency that can be cut, sanded, and stained to blend smoothly, easily, and unnoticeably into the wood around it. Wood putty is a flexible material that remains somewhat pliable even after it dries.
Wood filler repairs dry rot, fills knot holes, fills voids in wood from insect damage, and covers cracks and gouges in wooden trim and molding.
Wood filler is packaged in half-pint, pint, quart, and gallon plastic, metal, or glass resealable containers as well as 3.25-ounce tubes.
Most wood fillers are a neutral beige color and can be stained to match any type of wood. However, there are some that are pre-tinted, allowing you to quickly select a filler that matches the wood you are working with.
High-quality wood filler contains real wood fibers for superior filling, sanding, high-speed sanding, staining, and painting.

Q. When filling gaps in crown molding, how wide of a gap can I fill with wood filler?
A. Wood filler can be used to fill gaps up to an inch wide and an inch deep. However, many woodworkers carve a plug or wedge from a solid piece of wood slightly smaller than the divot they are attempting to repair, glue the plug or wedge in place, and then use wood filler to fill the remaining void.
Q. I am repairing an antique dresser with a deep gouge in the front of one of the drawers. How can I match the wood color exactly?
A. For small touch-up jobs, several brands of wood filler package their products in premixed small tubes of white, cedar, red sandalwood, black walnut, red oak, mahogany, teak, and black and grey shades to match most any wood color. With this type of product, if you can find the right match, you can easily repair furniture damage by yourself.
Q. I heard that in a pinch, I can use auto body repair putty, also known as Bondo, to fill gaps in wood if I am out of wood filler. Will this work?
A. Yes, auto body putty will work for a temporary fix, but it is a waste of time. Over time, auto body putty will dry, crack, and fall out of the hole or crack it was used to repair.
