The 7 Best Nail Hole Fillers for MDF and Wood Trim

Despite its simple name, nail hole wood filler is a surprisingly diverse and useful substance. It looks like putty and is available in a variety of different consistencies and textures.

Since it can dry at different rates you can use it for varied needs like for professionally repairing and filling the wood, drywall, or even plaster.

In this guide, I’ll go over some of the best options out there for filling trims (made of MDF wood) and how you should actually use them to fill the nail holes.

Also, I will go through the common uses and types of wood filler so that you can better understand what the product is used for. With that being said, let’s jump right in.

Causes of Nail Holes in Trim

Nail holes in door and window trim can occur due to several reasons.

Firstly, during the installation, if the trim isn’t aligned correctly using the nails or if excessive pressure is applied during installation, it may result in the formation of nail holes.

Additionally, wood trim’s susceptibility to shrinking or expanding due to fluctuations in humidity and temperature can loosen nails over time, resulting in visible holes. Structural settling or frequent usage may also exacerbate this issue, causing trim movement that loosens nails.

Furthermore, poor-quality installation materials or natural deterioration of trim materials can contribute to nail hole development. To mitigate this, prioritize proper installation techniques, employ high-quality materials like MDF, and conduct regular maintenance to address any emerging issues promptly.

Common Uses of Wood Filler

If you are planning to use a wood filler for the very first time or wondering how it can help you out in your project, let’s start by discussing some of the most popular wood filler applications.

You may be surprised at just how versatile this product can be in your home renovation job…

1- Filling Holes in the Trim

The first and most obvious use of this product is its ability to fix the small holes in the wood.

Small cracks, nail holes, or even holes made by insects are a common problem in old wooden trims and skirting boards at times when you want to refinish them. No matter how deep a hole you’re trying to fix, you can count on this substance to get the job done fairly quickly and easily.

Even if you see signs of wood rot (yellowish or brown spongy to touch wood), you can easily fix them using a wood filler. When you are done fixing the wood, simply leave it or paint over it to achieve a more natural-looking finish. These small repairs will actually prevent your painted window trim from rotting further.

2- Fixing Old Flooring and Furniture

If your hardwood floor or a piece of old furniture is looking a bit old and grainy, using wood filler to polish and restore its shine could prove to be a good move on your part.

To start, apply a thin coat of an oil-based wood filler onto your floor and give it time to set – avoid water-based wood filler as a floor polish, as it can damage your floors. Once dry and ready, use high-grit sandpaper to buff your floor and restore its shine.

Depending on the type of wood on the flooring and the extent to which it’s damaged, you may also opt to dye, stain, or refinish your floor with a sealant.

Keep in mind that if you are trying to fix your outdoor furniture that’s beginning to rot you will need to first peel away the bit of wood that is beginning to tear away and then replace it with thick heavy-duty wood filler.

For light jobs, wood filler is a great way to restore your furniture to its beauty. But you shouldn’t do this for furniture that bears weight, as wood hardener is generally accepted as a more appropriate substance for the task.

3- Smoothing Wood Grain

Don’t like the look of your hardwood floors? It could be that your wood is made up of long and wide grains that make it appear cheaper and less aesthetically pleasing.

If you find this to be the case, you can put a coat of wood filler over your wood and polish it out so that your MDF wood gains a more premium look. This is a popular technique for hardwoods such as white oak, which tend to be longer and wider and generally less attractive.

You may find it even better to apply a wood stain on top of your wood once you are done with the filler. This should have a nice polished surface that really catches the eye.

Can Wood Filler Be Used In Place of Wood Glue?

Wood filler can get the job done in a pinch as it works as well as wood glue in many cases. Of course, it’s not quite as cheap as wood glue, but it may come in handy if you already have it around.

How to Fill Nail Holes in Wooden Trim?

The holes in your window trims or baseboards may be quite small or rather large, depending on the size and type of nail used. Maybe you can use a putty, caulk, or filler that does the fixation job correctly. But the question comes how do you go about fixing them properly?

What follows are some simple, inexpensive ways to fill in the holes and divots created by the nails in wooden trim so that you can get a smoother surface to repaint them at a later stage.

Step 1 – Consider the Size of the Holes

Start by asking whether it’s worth the effort to fill in the holes in the first place. For those who use an Electric Brad Nailer, for example, that was calibrated to perfection, the size of the divots may not even be noticeable.

While all nail holes are apparent when viewed up close, you should stand at the closest reasonable distance that you expect anyone to see them and judge whether they are worth filling in. You may find that they are virtually invisible, which means that the effort and expense of doing tiny corrections are simply not worth it.

If they are quite small and you are planning on painting the MDF wooden trim, then the paint alone may be enough. But if you find that you can easily see them and they are noticeable, then you are ready for the next step, which is getting the right material to fill in the areas.

Step 2 – Choose Between Water-Based or Solvent-Based Wood Filler

You will need to decide which one is right for your needs, but it is true that water-based versions have some exceptional aspects. These are soft, easy to use, and can be applied quickly.

The downside of water-based wood fillers however is that if you have to spread them over a wide area, they can fall apart. But, considering that nail holes tend to be quite small, this is not much of a downside.

While solvent-based filler is far stronger when it hardens, it’s also more difficult to apply.

Oily, sticky, and messy, cleaning up after using a solvent-based filler will probably have you going for a water-based one the next time out. This is especially true if you are going to cover the trim with white paint or a colored stain.

Unless you need to cover some wide gaps, a water-based filler is generally the best choice.

Step 3 – Prepare a Hole Filler

Well, preparing a wood filler for nail holes isn’t as tough as you may think. To prepare it for the application you will need a wood filler, solvent and a putty spatula.

Depending on the kind of wood filler you pick and the type of wood you want to put it into, the solvent you use can be water-based or alcohol-based (such as thinner). If you want, you can even stain or pigment it using a common wood stain or an enamel.

When ready with your things…

• Mix the right amount of filler with the solvent using a putty spatula or a thin piece of plywood.
• When mixing, ensure that the end result is something like a consistent and malleable putty. It should neither be too diluted nor too dry.
• The right consistency will help in penetrating through the cracks very easily without getting the material wasted.

Remember – once prepared, your MDF wood filler will going to dry very quickly. So, without wasting your time, go and apply it wherever you need to. It’s good to fill even the smallest crack if you have got some excess filler left in the end, rather than going it wasted.

Step 4 – Use Your Finger for Filling

While a putty knife or a spatula has many uses, your finger is arguably far better when it comes to applying MDF wood filler to fix nail holes. Putty knives many times become difficult to use with small holes compared to large surfaces. So, you can save a considerable amount of time and effort by applying a little wood filler to the tip of your finger and smearing it into the nail hole.

Protection should be as important as filling the holes itself. So, it is recommended that you use vinyl or nitrile gloves with MDF wood fillers, as the residue left behind is easier to deal with if you are wearing the right gloves.

Step 5 – Sand the Surface to Get the Better Finishing

After the filler has dried, use a putty spatula or fine sandpaper to gently sand and remove the excess filler. This step is crucial for blending the repaired area with the surrounding surface and achieving a seamless finish. Just remember to sand lightly and gradually to avoid removing too much filler and compromising the finish.

Once finished, use a tack cloth to clean away any remaining material, and then you can start with the wood primer, sealant, stain, or paint that can result in a professional-looking repair.

What are the Different Types of Nail Hole Wood Fillers?

Wood fillers come in varied options some of them being more suitable for indoors while others are specifically formulated for outdoor use.

Indoor wood fillers typically prioritize factors like low odor, quick drying time, minimal shrinkage, and ease of sanding. On the other hand, outdoor wood fillers are designed to withstand harsh weather conditions, UV exposure, and moisture, ensuring durability and longevity.

With this information in mind, let’s now take a more in-depth look at some specific types of wood fillers so that you can get a better idea of which type will work for your project.

a) Solvent-Based

When encountering small holes or gaps in trims, cabinets, or wooden flooring, employing a solvent-based wood filler is an effective solution for concealment.

The application process is straightforward and these wood fillers are available in various hues, allowing for color matching with the timber used. However, it’s important to note that solvent-based wood fillers lack significant structural strength. Therefore, it’s advisable to refrain from driving nails or screws into areas filled with this type.

b) Water-Based

Water-based wood fillers consist of organic materials such as wood fiber, cellulose, and minerals like gypsum. They emit minimal odor due to their low volatile organic compound (VOC) content.

In certain situations, water-based wood fillers are regarded as more adaptable than solvent-based or latex-based alternatives, as they can be easily thinned with water for projects requiring a thinner filler consistency.

Additionally, these fillers offer the benefit of a quick drying time, typically around 15 minutes, and can be effortlessly cleaned up afterward using soap and water.

c) Epoxy-Based Fillers

Epoxy fillers offer added structural integrity and come in clear or colored varieties, typically packaged in cans or tubes. Being water-resistant and quick-drying these are also great for outdoor use for fixing tiny holes in your deck or siding.

Applying this filler can be somewhat messy, but precision is crucial as it’s challenging to sand once it sets. Once dried, epoxy filler provides greater strength than the wood it repairs. While you can insert nails or screws into it, it has a plastic-like look, making it best suited for concealed areas.

Can I Prepare a Homemade Wood Filler?

If you’re unable to find a wood filler that matches the color and texture of the wood you’re working with, you have the option to create your own.

One method involves blending sawdust and shavings with lacquer to produce a paste-like consistency. This homemade filler can be applied and sanded down once it dries, providing a natural appearance if smoothed properly, though it lacks significant structural integrity.

Another approach is to mix wood shavings and sawdust with wood glue. Once applied and dried, this mixture offers better mechanical strength but tends to appear darker than the original wood color. Additionally, it’s tougher to sand compared to the lacquer-based mixture.

Wood Filler vs. Wood Putty: Which is Better for Nail Holes?

While both these terms are interchangeably used in place of one another, wood filler and wood putty are different.

A wood filler is mostly water-based and great due to its malleability. But some of them are also created with chemicals such as latex, clay, lacquer, epoxy, or polyurethane.

One of the advantages of using wood fillers for nail holes is that it is a firmer compound that sets in extremely fast and allows you to sand or stain the product. The best part is that their cure time doesn’t exceed ten minutes. 

Wood putty, on the other hand, is obtained with a mix between calcium carbonate and an oil-based compound. It is meant to be used only with oil-based finishes, meaning that it isn’t as malleable as wood fillers are.

One of the pros of using wood putty is the fact that they are incredibly resistant. This means you can use them for outdoor furniture, as they won’t get damaged easily. Also, wood putty is more affordable than wood fillers.

A downside of wood putty is it requires a lot of time to set in. Depending on your project, the cure time for wood putty can range from two days to two weeks. 

Is Spackle and Wood Filler the Same?

Spackling compounds and wood fillers are not the same.

While wood filler (and wood putty) is used to fill the holes and gaps in the wood, spackle is majorly used for repairing the holes and cracks in the plaster or wall. In a pinch, you can use products such as caulk, soap, and even toothpaste as these are great alternatives to spackling if you want to fill the small holes and gaps in your wall.

However, if you want to fill the hole in the wood (like a push pin hole, dart hole, etc.), these may not be a reliable option to choose due to the fact that they may shrink and cause a divot over time.

Is There a Wood Filler You Can Screw Into?

Not all fillers are created equal—some are just there to look pretty, while others can take a screw like a champ.

When you need to screw into regular wood fillers won’t work. Your best bet for the task is epoxy wood fillers. These heavy-duty heroes harden into a rock-solid mass that can be sanded, painted, and yes—drilled into without flinching. Just remember: treat it right with a pilot hole, or you will risk cracking its confidence and structure.

Other screw-worthy contenders include two-part fillers like Roxil and solvent-based options like Bondo (which, let’s be honest, is more muscle than filler). Even Durham’s Rock Hard Water Putty lives up to its name—though it’s not exactly known for being flexible, so don’t expect it to do yoga with your screws.

Whichever you pick, the golden rule is – to let it cure completely before going in with tools and always drill smart, not hard.

So yes, you can screw into wood filler—just don’t try it with the soft, squishy stuff meant for nail holes and minor sins. Go big, go epoxy, and screw like a pro.

The Bottom Line

Repairing furniture or other wooden items – or merely building something from scratch – will often make you discover you need to fill some tiny holes. And it is only reasonable to experience such issues, as holes can represent gaps or variances in the MDF wood or where the nails go in.

Knowing this, make sure to use this guide as your ultimate reference for finding the type of wood filler that’s right for you, especially when dealing with MDF trim.
