The 10 Best Wood Fillers of 2023

What to Look for in Wood Filler

Types of Wood Fillers

Wood fillers generally fall into one of two basic groups: Those with a water base and those with a solvent base. Joe Ferguson, an architectural joiner at SkirtingsRus, advises, “Fillers often shrink as they dry, so generally speaking, two-pack, solvent-based fillers, which tend to shrink less than water-based products, should be used on larger areas of damage. Water-based wood fillers are fine for smaller, less conspicuous damages like nail holes.”

• Water-based wood fillers are easy to use, generally don’t have strong odors, and usually dry quite quickly, some within minutes. Most contain gypsum, cellulose, or wood fibers. They can usually be thinned with water if needed, and clean up with just soap and water. Water-based wood fillers, like the Aqua Coat Water-Based White Cabinet Grain Filler Gel, are quite versatile but are usually best for interior projects. The water-based gel formula goes on evenly, dries within 60 minutes, and provides a super-smooth finish.
• Solvent-based wood fillers are usually vinyl or epoxy. These fillers take longer to dry than water-based products, often an hour or more. They emit more VOCs and are smellier than water-based products, making good ventilation a must when using them. You’ll need a solvent-based cleaner to clean up after using a solvent-based wood filler, such as acetone or turpentine. However, these wood fillers generally are far more resistant to temperature extremes and moisture than water-based products, making them an especially good choice for exterior projects. The solvent-based 3M Bondo Wood Filler can be used to rebuild and restore rotting or damaged decking, fencing, siding, and other exterior surfaces.

Versatility

Wood fillers are intended for a variety of purposes, like filling nail holes, fixing baseboard cracks, or even helping to seal exterior siding. The right wood filler for your next project depends on how and where the filler will be used. If you are working on a small, specialized project, then it’s a good idea to search for a wood filler that has the most accurate color, texture, and resistance for the job.

However, in many cases, the user isn’t entirely sure where they will need to use the wood filler, so it may be more beneficial to opt for a light-colored, general-purpose wood filler that is resistant to water, dirt, and dust. This makes it possible to apply the wood filler almost anywhere and have it be suitable for the task. In addition, the light color means that it’s easily paintable to match the wall, ceiling, or baseboard, or any other surface.

Drying Time

One of the easiest mistakes to make with wood filler is to underestimate or overestimate the amount of time required for the filler to dry. Some products, like epoxy fillers, can take several hours to dry and will likely take another 24 hours to cure fully. These products can be beneficial for outdoor repairs, but it’s important to check the weather ahead of time so that the wood filler doesn’t get soaked before it has the chance to set and cure.

Latex or water-based wood fillers dry at a fast pace and they even become water-resistant within an hour or so. That makes them a great option for outdoor repairs. However, if you aren’t paying attention, the wood filler can be set before you have the chance to smooth out the texture and create a flush surface. Before deciding on a wood filler for your next project, be sure to note the expected drying time of the product, typically provided by the manufacturer in the product directions.
