The only recommendation is that you use this wood filler on hardwoods such as white oak; epoxy fillers do not work the best with softwood.

#2. Donald Durhams Rockhard Water Putty

Editor’s Rating: 4.8 out of 5 stars (4.8 / 5)

Donald Durhams Rockhard Water Putty

If you’re looking for the best wood putty for your money, this gypsum-based wood putty can be purchased as a 1 lb container or 4 lbs, depending on the task you have at hand. This is a heavy-duty putty that will fill and bond any type of material, from wood to even concrete.

The main advantage of Donald Durhams Rockhard putty is that it does not shrink over time. This means that it will last as long as the material you are trying to fill.

Winner: Best Wood Putty

Out of the box, it comes as a white powder that only requires water as a solvent to prepare. It cures as a hard and whitish layer, so it will require a layer of paint – especially if used on wood.

It is not a good wood filler for staining. 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.

All in all, it is a low-cost wood filler solution that simply works.

#3. Elmer’s E887Q Stainable Wood Filler

Editor’s Rating: 4.1 out of 5 stars (4.1 / 5)

Elmer's E887Q Stainable Wood Filler

Elmer’s E887Q is possibly the most popular wood filler on the market. This is a small 3.25-ounce tube that can be purchased as a two-pack, 3 packs, or 18 packs depending on the amount of wood filling you have to do.

This particular filler is made from actual wood fibers that give it a natural wood texture when cured.

Winner: Best Wood Filler For Staining

This is an excellent product for those looking for a wood filler for staining, as it can indeed be stained quite easily. However, it can be tricky to get the exact stain of your material.

We recommend that you apply, let it dry, and then paint over it. It can comfortably be used both indoors and outdoors (although it is not the best exterior wood filler), and since it dries solidly, you can sandpaper over with a power tool later on.

Since it is sold in small 3.25-ounce tubes, we recommend it only for those who have a small amount of wood filling to perform. If you have to renovate a big piece of furniture with deep holes, this product is not the best sustainable wood filler out there. There are better products for larger projects in our wood filler review.

This is one of the best woody putty options available.

It is not a good wood filler for staining, and it has a naturally light tan color when it dries. However, once it cures, you can sandpaper or drill over it, no problem.

Due to the high-density of this product, we feel it suits hardwood better than softwood. A typical application of this putty is filling and restoring rotted wood. Moreover, since it is a wood epoxy filler, it can be used both indoors and outdoors.

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. Here is a 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. 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 blends 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; they are not weatherproof.

#3. Vinyl-Based Wood Fillers

Vinyl-based wood fillers are very malleable and also very user-friendly. 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. However, it is still recommended to apply a layer of paint over this type of wood filler.

#4. Epoxy-Based/Liquid Wood Fillers

Over the years, epoxy wood fillers (sometimes known as liquid wood fillers) are quickly becoming one of the best 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.

Wood epoxy 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 the best 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 and wood cracks, 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 surface. 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 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 a wood stain.  Using a wood epoxy, liquid epoxy, or outdoor wood filler is the way to go when looking for a wood crack filler.

#4. Furniture Repair

Another very popular application of wood fillers is for furniture repair. If you have parts of furniture that have rotted 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.

#5. Material Bonding

One of the best things about wood fillers is that they also act like 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 Fill Wood

Wood Filler

As we will see, 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
  • Wood Putty Spatula
  • Sanding Sponge (or orbital sander)
  • A few pieces of rags

#2. Instructions

Step 1: Prepare the Surface

Use sandpaper to polish the area. Then, clean with a wet rag. This is simply to allow the wood filler to set properly without cracking and blend 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.

Step 3: Apply the Wood Filler

Generously apply the best wood filler you can find to the area with a putty knife. Smooth 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 on the wood filler. However, for the best effect, we recommend that you let it sit for at least 24 hours.

Step 5: Sand and Clean Again

Once it is dry, use an orbital sander or hand sandpaper to smooth the wood filler. You should see that it blends well with the surrounding material after a few 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. Once applied, you should not be able to tell the difference between the filled wood and the natural wood.

How to Prepare a Wood Filler

Depending on whether you are using an epoxy wood filler, liquid wood filler, or wood putty, there will be a slightly different approach. But in general, all you will need is the best wood filler you can find and a solvent.

Depending on the type of wood filler you choose, this solvent can be water or an alcohol-based thinner. You can use a putty spatula or a thin piece of plywood for mixing the wood filler with the solvent.

When mixing the wood filler with the solvent, make sure 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 it. Wood fillers will dry fairly quickly; once you have prepared it, there is no time to waste. 

Wood Filler vs. Wood Putty

Many people often confuse a wood filler with wood putty. This is understandable as they look 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, liquid, or polyurethane. Wood fillers are very quick to set and also very malleable, which makes it incredibly easy to apply.

Read More: Lacquer vs. Polyurethane

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

However, one of the greatest advantages 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. There is almost no wait time, thus 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.

The major advantage of wood putty is that it is cheaper and more readily available in a local hardware store. Ideally, 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. 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. Still, it can save you some money especially if you have a lot of applications to perform since it is considerably cheaper than wood fillers.
