Wood's natural look and texture add warmth and grace to any indoor or outdoor setting, but it's often dinged, chipped, or nailed full of holes. The intrepid DIYer must find the best wood filler and fix what time, elements, or clumsiness have ravaged. This review and buyer's guide covers wood filler use.
Choose the right filler for the wood you're patching to avoid problems. Some fillers don't last outside and aren't pliable enough for small jobs. Others are too soft to do more than cosmetic repairs. As important as colour is the filler's consistency and strength.
Wood filler is a paste used to fill cracks, holes, and other voids in wooden walls or objects. Almost everyone needs to fill a wood gap.
In this article, we are going to talk about some of the best wood filler available to buy. As there are great different types of wood fillers, various brands that promise and deliver questionable qualities, it is important to be careful. Before picking a wood filler, go through the following three key component checklist;
- Type of the wood filler: Depending on the type of solvent needed and used, the type of wood filler changes. They are either Water-based or other solvent-based. Depending on the purpose of use, your choice changes. Wood fillers made out of cellulose, wood fibre or gypsum will not have an odour, and they are minimal. They are water-sensitive and mostly used for indoor projects. If you need a wood filler for outside, you will go for solvent-based fillers, who are usually based out of epoxy and vinyl composites. Their strong smells distinguish them, but they will stick strong against in the outdoors as well.
- Ease of mixing and using: The next important thing to consider is how easy is the material to mix and use. While some of the wood filler putties are direct use (take out of the box to use), some require mixing. This means that some or other type of solvent are introduced for extra strength and better bonding. Both of these have their own merits. For small fractures or cracks in wood or for indoor projects, you want an instant putty wood filler but for larger cracks, mixing based putty will give you greater bond.
- Colour: The third thing to take care of is the colour. See, most of the wood fillers are wood-based brown or white. There are clear and transparent wood fillers as well. The emphasis on the colour of the wood filler must be given if you are filling up something that is having a greater visual presence. For instance, a crack on a chair of certain colour would want not to be visible, and then you would be using a specific colour as such. Or you can also go with a transparent or a paintable kind which allows the paint to stick on it.

Latex- and Solvent-Based Fillers
In most cases, a latex- or solvent-based filler is sufficient to patch small gaps or holes in interior cabinets or hardwood flooring. However, there are exceptions to this rule. Because these fillers already have a colour added, you can choose one that is a suitable match for the woodwork. They are simple to sand, which means you can apply them with a putty knife and easily remove any excess after they have dried.
Additionally, they are receptive to finishes. Pre-mixed wood fillers, which are typically sold in cans of a more manageable size, do not have a great deal of structural strength. If you use them to patch a hole that is more than half an inch in diameter, they will crack or sink and they will not be able to support a screw or a nail.
Use a filler that is based on epoxy when you need a material that has greater structural integrity, such as when you need to fill a crack that is widening in a floorboard or a void that has been caused by rot in a door jamb. It can be purchased in a tube or a can, and its appearance can either be clear or coloured. Because it is difficult to remove with sandpaper, it must be applied with caution, and any excess must be kept to a minimum.
In most cases, the resulting repair is significantly more robust than the wood itself. It is possible to screw into it, despite the fact that it has the appearance of plastic and only superficially resembles wood. When the structural integrity of the building is more important than its appearance, use it either indoors or outdoors.
Exterior Wood Filler and Caulk
Filler material for exterior cosmetic patching jobs needs to be water-resistant and capable of expanding and contracting with temperature changes. As a result of its elastomeric properties, exterior wood filler, which is sold in cans, satisfies the requirements outlined here. Utilize a putty knife to apply it, and then paint over it if you so choose. Acrylic latex and butyl caulk are both resistant to the elements and can be painted.
Additionally, these caulks are available in tubes that can be loaded into a caulking gun, making them advantageous choices for filling in long cracks in siding and spaces between boards. Choose a silicone caulk with a colour that matches the surrounding area because it cannot be painted after it has been applied. Silicone caulk is highly flexible and resistant to the elements.
When woodworkers are unable to locate a filler that is an exact match for the type of wood they are working with, they frequently resort to creating their own. They combine some sawdust or shavings from the wood with a small amount of lacquer, then knife it into the hole they are filling and sand it until it is flat. This kind of filler isn't very strong, so it's not appropriate for filling in large holes, but it does provide a good cosmetic solution.
Sawdust combined with carpenter's glue is one alternative that can be used. Glue produces a stronger filler, but it also significantly darkens the wood, which means that the repair will almost never be completely undetectable. In addition, sanding glue is more difficult than sanding lacquer.

How To Use Wood Filler
The process of applying wood fillers is simple, although it involves several steps and, because of the nature of filler, time is of the essence. Make sure you've prepared everything, including the filler, solvents, a putty spatula, and a putty knife, before starting.
- Sand down the surface thoroughly to ensure a tight bond.
- Before you apply the wood filler, you'll need to prepare it first. This involves mixing your filler of choice with the right solvent. You can use a putty spatula to make sure the filler and solvent are well-mixed. Aim for a malleable and consistent substance that suits the task. If it's too thin, it won't cure well, and if it's too thick, it won't fit and might crack.
- Keep in mind that most fillers harden quickly, so you only have a small window of time between preparing the filler and applying it.
- Use the putty knife to apply the filler on the surface in the right amount. Don't use pressure on the filler. Let it seep into the holes or cracks naturally.
- Let the filled wood dry.
- Give the surface a good sanding to smooth the rough edges and remove any excess filler.
- Apply paint or stain as needed.
As a pro tip, it's always better to give the filler enough time to dry regardless of the time advertised on the package. A good bet is 24 hours from the time you're done applying the filler. This gives the cured filler enough time to bond with the wood and prevents cracking.
Factors To Consider While Buying a Wood Filler
The following are some of the key factors that you need to consider while buying a wood filler.
Type of the wood filler
You must have realised by this point that there are two different bases available for wood fillers. soluble in water and composed of a solvent. Your decision will change and vary depending on the specifics of your use case. For instance, if you need to fix something in your interiors, you would choose to go for a water-soluble wood filler because it will give you greater hold and dries up very quickly.
This would be the option that you would choose if you needed to fix something in your interiors. However, if you need to repair something that is located outside, you should most likely opt for a wood filler that is solvent-based. This type of wood filler will have stronger bonds and can withstand any climate, regardless of whether it is hot, humid, rainy, or cold.
Ease of mixing and using
Wood fillers that are water-soluble are very simple to combine and work with. The vast majority of the time, they are sold in packages that contain ready-made putties that simply require you to add something to them and then use them. You do not require any other kind of mixture.
Wood fillers that are based on solvents might require some mixing because they will be subjected to a wide variety of factors, including their adhesive power, colour, and climate resistance, amongst others. Small cracks in chairs, cupboards, and other interior projects like these may require readymade wood filler putties, but large barn-based projects should not use putties that can be easily mixed. Go for solvent-based models.
Consider the wood filler's colour. This is because wood filler is sometimes applied in showcase eyes.
Most wood fillers are wood-colored, but there are many transparent variants. Again, it depends on the project. For internal projects, use any colour. Choose a complementary colour for other areas.
Paintable non-colored putty is another option. These are paint-friendly and great for any project. Just dab and add paint.
Speed of healing
Some wood fillers heal very quickly (within a few minutes of application), while others might take as long as an hour. However, the length of time it takes to heal has a negative correlation to the quality. The longer it takes to heal, the more powerful the bond that is formed by sticking together will be. Therefore, you should not undervalue wood fillers that slowly heal.
Consistency of the Filler
The consistency of the filler, whether it be thin or thick, will also play a part in assisting you in selecting the appropriate product. Therefore, at this point, you need to think about the void size of the project. Is it a huge quantity or quantity? Wood fillers that have a thick consistency are the optimal choice because they are able to fill pores and, the majority of the time, open grain woods.
On the other hand, a consistency that is neither as thick nor as thin is selected for smaller cracks. They are simple to mix and use, and they also fill in the cracks more quickly than other options.

FAQs About Wood Fillers
While the chemical formula of wood putty can damage exposed wood, wood filler is made to bind directly to the natural wood and doesn't need stain before application. Patch holes inside the home with this quick-drying, paintable, stainable, and sandable wood and grain filler.
It won't have a problem with shrinkage like other wood filler options do. However, it does have its limits with how much it can cover. Anything more than 3/8-inch isn't advisable. Aside from that, you can sand, paint, and wood stain putty after it hardens.
Yes, wood filler hardens. Wood filler does not contract or expand according to the outdoor elements and hardens much faster than wood putty. Because of the hardening behavior of wood filler, it is great to cover major damages on indoor wooden furniture and repair them from inside.
Use vinyl spackling compound or water-based wood filler to fill small holes on interior surfaces. When applying wood filler, over fill the hole slightly to compensate for shrinkage as the filler dries. Once the filler has hardened, sand it smooth and prime and paint or stain, as desired.
Yes, you can drill and screw into epoxy-based wood fillers when dry. However, it is often essential to drill a hole into a wood filler before dragging a screw into it. Screwing directly into an epoxy can cause it to crack since epoxies are generally very dense.
