    Types of Wood Fillers

    Wood filler comes in different materials. Knowing which wood filler has which properties can make a huge difference in the ease of repairing your wooden surface.

    cellulose-based pastes or powders are the most common wood fillers. Long-lasting and inexpensive, they provide a tough, easy-to-apply surface that takes stains and colours well.

    Vinyl or latex wood fillers are easy to shape and mould to match non-flat surfaces. If applied too thickly, they crack easily. These fillers are weatherproof and stain-resistant, so they can be used outside more easily and reliably than cellulose wood fillers.

    2-part epoxy wood fillers are toughest. These require more preparation time than other wood filler putties because they come in 2 parts that must be mixed, but they offer a high enough bonding level to be used as glue for attaching wooden surfaces. Epoxy-based wood fillers are tough and weather-resistant, making them ideal for outdoor use.

    How to Use Wood Filler

    Following a few simple guidelines makes wood fillers easy to use. As long as you use an appropriate wood filler and prepare it properly (e.g., mixing epoxy filler), the following steps should work well.

    Sand the filling surface to improve bonding. Apply filler with a putty knife without too much pressure, and let it fill cracks and gaps.

    Dry the filler thoroughly. Even if it's fast-drying, give it 24 hours. After that, sand the surface to finish.

    Uses for Wood Filler

    Wood filler has many uses besides repairing scratches. Different types of wood filler are better for different applications; knowing the full range can help you get the most out of your choice.

    Most wood fillers fill holes. A good wood filler can fill holes of any depth. Notable. Vinyl-based wood filler cracks when applied thickly, so it's not ideal for filling holes.

    Any wood filler can smooth rough wood surfaces like oak's coarse grain. A thin layer of wood filler applied to rough wood can be polished to a high shine and smoothness, making rough wood surfaces look smooth and professional.

    Non-water-based wood fillers are good for smoothing a wooden floor. Thin oil-based wood filler can be applied to any wooden floor, then polished and smoothed with fine sandpaper. Finish with stain and varnish.

    2-part epoxy is a strong wood glue. Most wood glues are cheaper and easier to use, but a 2-part epoxy filler gives a stronger bond with thicker glue that also fills gaps.

    Wood filler can fix rotten wood furniture (as long as the rotten parts are not in load-bearing parts of the furniture). Remove rotten wood and fill the gap with wood filler. Sanding, painting, or staining to match the rest of the furniture should hide the repair.

    Water vs. Solvent Fillers

    Wood fillers are either water- or solvent-based. Either can be used to fill wood voids and/or pores, but they have a number of differences.

    • Water-based wood fillers are generally comprised of cellulose, wood fibre, or gypsum. They tend to have a less potent odour, as they emit few if any, volatile organic compounds (VOCs). Some water-based wood fillers are considered more versatile than their solvent-based counterparts because they can be readily diluted with water and used in projects requiring a thinner filler. Water-based fillers typically dry in about 15 minutes, and the cleanup after use requires only soap and water.
    • Solvent-based fillers tend to be made of vinyl or epoxy. They have a higher VOC content—and are correspondingly smellier. Solvent-based wood thinners take about an hour to dry and cleaning up after use calls for acetone or turpentine. Cost-wise, solvent-based fillers are pricier than water-based because they're more resistant to water, humidity, extreme heat and cold, and rot, and so best suited for exterior wood projects and applications.

    Choosing the Best Wood Filler for Your Project


    Wood fillers are typically designed to perform one or more of a number of distinct functions. Some are suitable for filling voids in all types of wood, including divots, holes, and gouges, while others are not. Others are formulated to fill pores in open-grain woods that have large pores visible to the naked eye, such as oak or elm, to smooth their naturally coarse texture. This is done in order to improve the appearance of the wood. (As the filler fills in the pores, it evens out any unevenness, resulting in a finish that is especially desirable on furniture.) The most versatile fillers can be used to either fill voids or pores, depending on the application.


    Wood fillers can either have a thick consistency (similar to putty) or a thin consistency (similar to pancake batter). While thinner fillers are utilised primarily for the purpose of filling pores in open-grain woods, thicker fillers are utilised primarily for the purpose of filling voids. It is essential to select the appropriate filler consistency for your undertaking, as fillers with a thicker consistency contain large particles that do not easily fit into the pores of open-grain woods, and fillers with a thinner consistency typically do not have the body necessary to fill voids in an adequate manner. (Here's a helpful hint: If you're in a pinch, you can dilute some of the more viscous fillers with water to fill pores.)


    White or wood-inspired fillers are most common; clear versions fill pores. If you don't plan to stain or paint the piece, choose a filler that matches or contrasts with the original wood colour. If you plan to stain or paint the cured filler, choose a white or lighter shade than the stain or paint.

    Application environment

    Fillers are generally labelled for "interior-only" or "interior/exterior" use as an indication of how well the filler will hold up in the stated environment both during the application, while wet, and post-application after it has dried.

    • You can safely apply interior-only fillers indoors to wooden pieces that will stay indoors—e.g., a coffee table. Apply that same product outdoors and to a piece that will live outdoors, such as a patio table, and the filler will be more likely to freeze or harden while wet from exposure to extreme cold or heat, or crack or shrink over time once dry.
    • You can safely apply interior/exterior fillers in either environment and to wood pieces that will live indoors or out since they can withstand extreme weather without hardening during the application or cracking/shrinking once dry. Water-based interior/exterior fillers are more versatile because they're durable enough for outdoor projects, yet emit virtually no odour while wet. While solvent-based interior/exterior fillers are safe to apply in both environments, you're better off using them for heavy-duty outdoor projects (e.g., filling gouges or replacing rotted decking), where their highly weather-resistant solvents can handily defend against the elements and the fumes they emit. At the same time, wet will quickly dissipate in the air.

    Tubs, tubes, and sticks hold wood fillers. Those in tubs can be applied directly with a putty knife or spreader or must be mixed before use. Stick fillers are ripped off and applied by hand, while tube fillers are squeezed out. Tubs are the most cost-effective and best for larger projects, while sticks are best for repairing scratches and cracks.

    It would be tedious to list all wood filler's uses. When you consider all the wood products we use, the list is long. It can repair damaged wood and strengthen weakened wood. Load-bearing timbers shouldn't be repaired with wood putty. Wood filler can strengthen and beautify even these surfaces. Thanks for reading this article, and good luck!

    FAQs About Wood Rot

    Look for signs of wood damage around the home. This comes in many forms: discoloration, shrunken size, cracks, and splintering. As rotting progresses, it breaks down the cellulose in the wood. This causes the wood to become soft and dark in color; it also gets smaller in size as the cellulose is consumed.

    Termite damage can leave wood looking wavy or with areas that appear to be hollowed out. Wet rot can cause wood to look darker than surrounding areas and cause it to feel soft and spongy. Dry rot can cause the wood to crack and crumble when it is touched. You may be able to see fungi growth on wood that is rotting.

    Second of all, most termites require an abundant amount of water in order to survive. These two factors make rotting wood particularly attractive to termites. This is because wood begins to rot after it is exposed to heavy amounts of water over an extended period of time

    Wood rot is a form of decay triggered by the combination of moisture and fungi (microscopic organisms). In order for fungi to set up shop, the wood must be continuously damp; fungi will not grow on dry wood.

    Wet rot fungus

    Depending on the specific genus of wet rot growing the colour will vary from brown rot to white rot. These strands will later develop a white skin or coating and eventually a series of small fruiting bodies that look like tiny “off-white” mushrooms.
