This means that it will last as long as the material you were trying to fill.

It is not a good wood filler for staining. Just keep that in mind. Additionally, since it is water-based, it is recommended to use only indoors. However, with a thick layer of paint and weather treatment solution, it can be used outdoors as long as it does not face direct sunlight.

Types of Wood Fillers

There are several types of Wood fillers on the market. In order to find the best wood filler for your need, you will first need to understand the different types of Wood fillers that exist. Here is a quick and concise overview.

#1. Cellulose-Based Wood Fillers

Cellulose wood fillers are one of the most common available. They come as a dry mixable paste or powder that is suitable in a wide range of solvents, ranging from water to alcohol-based ones. The main advantage of this type of wood filler is that they are readily available in any hardware store and can be stored for years. Indeed, they have a very long shelf life and are quite inexpensive. You will require a little bit of work to prepare this type of wood filler, but most of the time it only takes only a few minutes and they have a long-lasting effect, especially when used to repair wood. This type is also an excellent wood filler for staining, especially when used in thin layers.

#2. Gypsum-Based Wood Fillers

As its name suggests, gypsum-based wood fillers consist of mineral powders. They are easily suitable in water to form a solid substance that is not easy to break once set. They also have a distinct crystalline and transparent look that makes gypsum-based wood fillers morph with the surrounding material in a superior way. However, the caveat with gypsum-based wood fillers is that they stain easily over time. You will most likely require a layer of paint on this type of wood filler for the best effect. Moreover, gypsum-based wood fillers are also recommended for indoor use only as they are not weatherproof.

#3. Vinyl-Based Wood Fillers

Vinyl-based wood fillers are very malleable and also very user-friendly. Basically, this fee that is a mix of calcium carbonate and poly-vinyl acetate that acts as a catalyst. Vinyl base wood fillers are the quickest to set but when applied as a thick layer, they are prone to cracking. Therefore, this type of wood filler is recommended to be used as a thin coat only. The major advantage is that since it is plastic-based, it is weatherproof and can be used outside as it would not stain easily. However, it is still recommended to apply a layer of paint over this type of wood filler.

#4. Epoxy-Based Wood Fillers

Over the years, epoxies are quickly becoming one of the most popular type of wood fillers on the market. Epoxy is a petroleum-based putty filler that can also be used as an adhesive glue. It is usually a two-part formula that needs to be mixed and has a relatively short dry time. Epoxy-based fillers are excellent outdoor wood fillers since they are weather resistant and very tough.

Wood Filler Applications

There are different types of wood filler applications. They are not restricted only to repair wood. Here are a few common usages for wood fillers.

#1. Hole Filling

As per the original intent of wood fillers, hole filling is the most common use of wood fillers. No matter how deep the hole is, a wood filler should be able to accomplish the job. However, before proceeding you will need to smooth the surface with a high-grit sandpaper and remove any debris and dust before applying the wood filler. You can use any type of wood filler to fill deep holes, except for vinyl-based wood fillers that have a tendency to crack when used in thick layers. Feel free to apply a layer of paint later on.

#2. Wood Grain Smoothing

There are many types of wood that have long and wide wood grains. Wood such as white oak is a good example. One way to make this type of wood more aesthetically pleasing, is by applying a thin layer of wood filler on top and then polishing it out. This leaves a smooth and reflecting surface that looks premium. You can then apply a layer of wood stain to make it even more appealing.

#3. Flooring

You can also apply wood fillers on wooden flooring. However, we do not recommend water-based wood fillers for flooring applications for obvious reasons. First spread a thin layer of an oil-based wood filler on your floor and allow it to set. You can then use a high grit sandpaper to polish and resurface the wood floor. Depending on the type of wood filler use, you may or may not need to apply wood stain. But this, is on a case to case basis.

#4. Furniture Repair

Another very popular application of wood fillers is for furniture repair. If you have parts of furniture that has rot away, you can carefully remove them and reapply a thick layer of wood filler. However, bear in mind that to get a sustainable wood filler, your furniture must not be a load bearing one. If that is the case, then it is recommended to use a wood hardener rather than a wood filler as wood hardeners are tougher than their counterparts.

#5. Material Bonding

One of the best things about wood fillers is that they also act as a tough and durable glue. If you want to stick two pieces of material together, you can still use an appropriate wood filler instead of wood glue. Of course, wood glue is much cheaper than wood fillers but it is nice to know that it is a possibility in case you have to.

How to Wood Fill

Wood Filler

As we will see in a stepwise manner, anyone can apply wood fillers in a professional way. It is a quick and easy process that requires almost no skill to perform. Here is how it is done. Bear in mind that you will still need some basic materials listed below.

#1. Materials

  • Wood Filler
  • Wood Glue
  • Putty Spatula
  • Sanding Sponge (or orbital sander)
  • A few pieces of rags

#2. Instructions

Step 1: Prepare the Surface

Use a sandpaper to polish the area. Then, clean with a piece of wet rag. This is simply to allow the wood filler to set properly without cracking and merge perfectly with the surrounding environment.

Step 2: Choose Your Wood Filler

Next, you will need to choose the type of wood filler. Whether you are using it outdoors or indoors is an important factor to take into account when choosing the right type of wood filler. The end result is that you need a sustainable wood filler, and not just any type of wood filler you can grab your hands on. Now that you have, let’s go to the next step.

Step 3: Apply the Wood Filler

Generously apply the wood filler to the area with a putty knife. Smoothing it out without applying too much pressure. Let the wood filler work its way through the crack.

Step 4: Let it Dry

Let it dry completely. The drying time will depend from wood filler to wood filler. However, for best effect, we recommend that you let it set for at least 24 hours.

Step 5: Sand and Clean Again

Once it is dry, use an orbital sander or a hand sandpaper to smoothen the wood filler. You should see that it blends well with the surrounding material after a few sandpaper passes. This is when you stop and clean it with a wet rag once again.

Step 6: Final Treatment

Once done, you can apply a layer of wood stain, veneer or paint depending on your choice. Once applied, you should not be able to tell which part is wood filled from the rest of the material.

How to Prepare a Wood Filler

So, you want to prepare a wood filler? Let’s see just how easy it is! All you will need is your chosen wood filler, and a solvent. Depending on the type of wood filler you choose, this solvent can be water or an alcohol-based liquid like thinner. Additionally, you can use a putty spatula or even a thin piece of plywood for mixing the wood filler with the solvent.

When mixing the wood filler with the solvent, you need to make sure that you get a consistent and malleable putty. You do not want it to be too diluted or too dry. It needs to have the right consistency to penetrate the cracks easily. Also, bear in mind that you have a limited amount of time to prepare the wood filler and apply. Wood fillers will dry fairly quickly so once you have prepared it, there is no time to waste. Next time someone asks you what’s a wood filler and how to prepare it? Well, now you know!

Wood Filler vs. Wood Putty

Many people often confuse a wood filler with wood putty. Understandably so as they both look so much alike and do the same task of filling gaps. Here are the major differences between a wood filler vs wood putty.

#1. Wood Filler

Essentially, a wood filler is a water-based putty. It consists generally of chemicals like latex, clay, lacquer, epoxy or polyurethane. Wood fillers are very quick to set and also very malleable which makes it incredibly easy to apply by almost anyone.

Read More: Lacquer vs. Polyurethane

One of the best advantages of wood fillers is that you can mix sawdust or pigments to it before application. This gives it an aesthetically pleasing texture that requires little to no after work like wood staining.

However, one of the greatest advantage of wood filler vs wood putty is the quick cure time of wood fillers. Many water-based wood fillers can cure in 10 minutes or less. This is pretty remarkable as there is almost no wait time and this type of filler allows you to gain more in productivity, especially in a professional environment where you repair furniture for other people.

#2. Wood Putty

Wood putty, on the other hand, is calcium carbonate and oil-based. This makes it only applicable for oil-based finishes. It is not as versatile as wood fillers but more resistant, especially when used outdoors since it is weatherproof right out-of-the-box. The major advantage of wood putty is that it is much cheaper and more readily available in a local hardware store. Ideally, a wood putty is used on a large project like wood flooring where it would cost too much to apply a wood filler.

However, as already pointed out, it has a limited set of applications and to top it off, wood putty requires at least 48 hours to two weeks to set properly. This is a very long time compared to wood fillers that can set in a matter of minutes. At the end of the day, wood putty is only recommended for use on oil-based finishes but it can save you some money especially if you have a lot of application to perform since it is considerably cheaper than wood fillers.
