Things to know before buying Wood Filler

What Is Wood Filler?

Wood filler is a product used to create smooth surface repairs to dents on wood. Wood filler is sandable and is intended for unfinished wood that will be painted on to seal it. The composition of wood filler is made of a binding agent and a filling substance. Most wood repair products have the consistency of putty, which is easier to work with and offers color options to match the project for even finishing results.

There are different types, including water-based, which can be thinned simply by adding more water, and solvent-based, that need acetone or turpentine to mix. 

 When To Use Wood Filler?

Basically, anytime you have damaged wood in the house. Wood filler is used on both small and bigger repairs from patching minor imperfections on your hardwood floors to repairing a rotting window frame.

Most people think wood fillers are used to fix doors and walls. The truth is wood fillers can be used on a variety of repairs around the house. You can fix dents on your floor or your old furniture or replace parts of rotting wood inside and outside the home.

The first thing you need to do is assess the damage. If it’s superficial, a thin coat of the filler will even out the surface, which can then be stained or painted. A clear wood filler works best for floors. 

If your repair is extensive, for instance, repairing a rotting leg on your patio chair, you will need to do more work by first removing the rotten wood and then use a polymer-based wood putty as it’s thicker thus creates a strong bond and is works well for outdoor jobs.

Types of Wood Fillers

There are several types of wood fillers on the market. Before choosing the best wood putty for your project, you will first need to understand the different kinds of Wood fillers that exist. Here is a quick overview.

1. Cellulose-Based Wood Filler

This is the most common type of wood filler in the market, which comes as pastes, and powder that can are mixed with a wide range of solvents ranging from water to alcohol-based ones. You can always find one at your local hardware store; they are readily available.

They have a durable and affordable, and provide a tough and easy to apply surface that is stainable and paintable.

You will require a bit of work to prepare the mixture, which takes a few minutes, but will give a lasting effect when used to repair wood. It is excellent wood filler for staining when applied in thin layers.

2. Gypsum-Based Wood Filler

Gypsum-based wood fillers are made from mineral powders and water to form a crystalline substance that bonds strongly with wood to form a solid surface that doesn’t shrink nor crack. Gypsum wood fillers are best suited for surfaces that will be painted on to because the putty will cause staining. Gypsum Based wood filler is recommended for indoor use because it’s not weatherproof.

3. Latex Wood Filler

Latex-based fillers are also known as vinyl wood fillers. They are made from polyvinyl acetate emulsion, which acts as a binder and a calcium carbonate. They are very malleable, thus easy to apply and don’t require much experience to use.

Latex base wood fillers are quick to set, and when applied in a thick layer, they are prone to getting cracks. Therefore, this wood filler is best used as a thin coating on wood.

The great thing about this filler is it’s made out of plastic; therefore, it’s weatherproof and can be used for outside projects. Although this type of wood filler does not stain, it leaves a white residue that needs to be painted.

4. Epoxy-Based Wood Filler

Epoxies are two-part formulas that are petroleum-based putty that can be used as an adhesive. Epoxies are gaining popularity because they can be used both inside and outside the house for repairs because they are moisture resistant.

This two-part putty needs to be mixed and have a short dry time. Once dried, the filler forms a strong bond that can be sanded and painted on. The caveat, this type of filler doesn’t tolerate wood stains well.

5. Water-Based Wood Fillers

Water-based fillers require water to activate the putty. They mostly come in powder form, and the user uses a small amount of the powder to mix with water before application.

The paste is easy to apply and dries quickly into a solid rock substance that can be sanded, drilled, and painted on. Because it’s water-soluble, it’s recommended for use indoors only. Water-based fillers can also be used outside if the area is weather treated.

Size

Wood fillers come in many sizes from small tube to the large cans containing pounds of the product. Most latex-based fillers come in small containers that will fit in your wood repair kit. For instance, Elmer’s wood filler comes in a 3.25oz tube, while an epoxy system like Abroton WoodEpox comes in two pints weighing 1.23 pounds. Commercially wood fillers come in pails.

Indoor or Outdoor Use

Most wood fillers come labeled for indoor or outdoor use or both. The choice of putty will depend on where your project is located. Water-based and gypsum fillers are best used indoors, while latex based fillers are made out of plastic that holds up well in all kinds of weather. Plastic wood fillers make the best exterior wood putty as they are water-resistant. 

A great in-between is epoxy wood filler that is easy to work with and works well for both indoor and outdoor repairs.

Wood fillers are formulated for one or more tasks that are usually indicated on the packaging. Some are suitable for filling holes or gouges in all wood types. Others are formulated to fill pores in open-grain woods with large pores visible to the naked eye. A wood grain filler is used to smoothen out the coarse textures of hardwoods such as oak, before staining or painting.

Color Matching

Most wood fillers are white or wood-inspired colors. If you don’t plan on staining or painting the repaired area, go for a that best matches the original wood color of your project. There are colored wood filler options to choose to get a color match that is close to the color of your wood. If you intend to do a paint job on the furniture, make sure the filler cures completely for it to take paint well. Liquid wood filler will work well as you can mix in the color of your choice when preparing the putty. Be sure to pick a product that is labeled stainable and paintable. Some wood putty, especially the epoxy kind, doesn’t take staining and color well.

Drying Time

If you intend to get the job done fast, you should pick a filler that has a shorter drying period. However, always consider the place of the project you are repairing. Ask yourself where you are going to place the furniture.

Cellulose-based fillers dry fast and but if you are going to leave your furniture exposed to the elements, you are better off considering epoxy or latex-based filler that takes a little longer but performs better.

Also, if you are going to get the details right, go for a longer drying time that will give you time to mold and make adjustments before it fully dries.

Smell

Wood fillers are either water or solvent-based. Water-based fillers have cellulose wood grains or gypsum and are almost odorless. This is because they emit few if any volatile compounds (VOCs).

Solvent-based fillers are made of vinyl or epoxy. They have more VOC content, therefore smellier. They take longer to dry, cure, and need turpentine or acetone to clean up. They are more water-resistant, can tolerate environments with high humidity, extreme heat, and cold temperatures, and are best suited for exterior applications.

Stain or Painting

The choice to stain or paint will depend on the wood type and the extent of repair. Small repairs to even out the wood surface is done by applying a thin layer of putty to close wood pores then stained to retain the original aesthetic of the furniture piece. In this case, choose of wood filler that best matches the color of your project and readily accepts stain. Gypsum-based fillers will be practically undetectable over your wooden furniture, but they are best used indoors.

If you opt to paint over your project, any paintable wood filler will do. Simply apply then and sand it. Wait for it to cure before applying the paint of your choice. You will need to use more than one coat of paint to get the color match you desire.

Wood Filler Applications

Here are a few projects when to use wood filler.

1. Furniture

Use wood filler to fill both small and large gaps in the wood. When your furniture has minor dents on the surface, use a filler to even out the surface, sand, and stain the area for a better look.

If your furniture is rotting, use wood filler that is rot-resistant to repair the damaged area, then proceed to sand and paint your furniture. The type of filler you will need will depend on the wood type. Some fillers work best on hardwood and others on softwoods.

2. Flooring

On floors, you will need to use thin wood floor filler unless you need to fill deep cracks. In this case, you will need to apply it evenly, wait for it to dry before applying the stain. If your floor is made from hardwood, use hard floor filler for the job.

3. Hole filling

When filling holes left by nails and screws on your walls, you will need to use a thick wood filler to fill the gaps and cracks. You need to prep the cracks or holes before using wood filler. Use a sandpaper to smooth out the inside and remove all the sawdust. Use a putty knife to press the filler in and smooth the top. Once it dries, sand the top until it’s even with the wood surface. You can also paint or stain over the putty once it has been sanded smooth.

4. Wood Grain Smoothing

Most hardwoods have large pores that need to be filled before staining because the wood absorbs a lot of paint. A thin coat of wood filler closes these pores giving the wood a smooth surface to stain and paint on. After applying the filler, allow it to dry, then sand it and use the stain.

5. Material Bonding

Wood fillers can be use to join two or more piece of wood together. Wood putty can be used instead of glue because it gives a durable and robust hold. The only downside is wood fillers are more expensive than glue, so if you r project is quiet big, use glue. 

How to Wood Fill

Applying wood filler is an easy process as long as you have the right wood filler for the job. You don’t need any technical skill to do it right. Here is how to fill large holes in wood.

You need some basic materials for the job.

#1. Materials

• Wood filler 
• Putty spatula 
• Sanding paper 
• Cleaning clothes 

#2. Instructions

Step 1: Prepare the surface 

Use a rough grade sanding paper to expose the area by removing any stain or paint. This can be done by hand or by use of a rotary sander. Clean using a wet rag to remove all the debris.

Step 2: Choose your wood filler

Your choice f wood filling will be determined by the project you are working on. You have to take into account whether the furniture is used indoors or outdoors when choosing the right filler. To get a proper repair job, you need suitable wood filler that will last long.

Step 3: Apply the wood filler

If your filler is a powder or an epoxy, it will need to be prepared first. Apply the wood filler to the area with a putty knife making sure you don’t apply too much pressure. Smooth it out and take out the excess. 

Step 4: Let it dry

Let the area air-dry entirely. The drying time will depend on the wood filler use. Some wood filler can take only 30 minutes to dry while others take hours. We recommend that you let it sit for at least 24 hours.

Step 5: Sanding

Once the area has cured, use your sandpaper or rotary sander to smoothen the area out. After a couple passes, you will start to notice the area blending with the surrounding wood. When the area is smooth to your satisfaction, use a wet cloth to take clean the area again.

Step 6: Staining and painting

You can apply a wood stain or paint depending on your choice. The repaired area should look like the rest of the wood.

How to Prepare Wood Filler

Wood fillers are either water-based or solvent-based. Preparing wood filling is easy; all you need is to choose the filler that works for your need and get a solvent. The wood filler will come with instructions on how to mix it.

The solvent can be water or alcohol-based, depending on the wood filler. You will need a can and a spatula. Scoop the amount of filler you need and add the solvent till you get a paste that you can work with. If it’s too thin or too thick, it won’t work well. Your putty must be malleable to penetrate the cracks easily,

Keep in mind the drying time of the filler. Once you have prepared the paste, you only have a couple of minutes to work with it before it dries. Prepare small amounts at a time, so you don’t end up wasting any product.

What to Look For in Wood Filler that Accepts Stain

Before purchasing the best stainable wood filler, know how you are going to use it, are you repairing a large or a small area? Where is the repair taking place, outside or inside your home? What type of wood are you working on? 

This way, you will be able to choose the right product for the job. Most wood fillers will come labeled if they are stainable or paintable on the container. Stay away from epoxy system fillers, as they don’t stain easily. 

Wood Filler vs. Wood Putty

Manufacturers will label wood fillers as wood putty. It’s basically the same product. However, there is a slight difference. 

Wood filler is water-based putty. It’s made out of latex,epoxy, or clay. This type of wood filler sets quickly and is malleable, making it easy to work with. 

The great thing about wood filler is the quick cure time — most of them cure in 15 minutes. You can also add pigments or sawdust before applying it. 

On the downside, this filler doesn’t perform well when used outdoors, and it dries out if the can is left open or freezes. 

Wood putty is calcium carbonate and oil-based products. It has a thicker consistency than water-based fillers and best for exterior works because it’s weatherproof and makes a watertight bond between the wood. 

Due to its thick consistency, it has limited applications and takes anywhere from 3 days to two weeks to fully cure. That is a long time compared to the wood filler that set in a matter of minutes. 

Wood putty is recommended for use on oil-based finishes and larger projects because it’s inexpensive. If you need to do small repairs quickly, wood filler is a better choice.  

Interior or Exterior Use

Wood fillers for interior use do not need to be weatherproof, but the fillet must strong to avoid shrinking or cracking.

For exterior use, the wood filler must be weatherproof; it should be rot and mildew resistant and above waterproof.

Where to Buy Wood Fillers

Your local hardware store will have a variety of wood fillers for you to choose from. You may find the products are more expensive and the choices limited at times

Another place to get your wood filler is online retail stores. There is more variety at competitive prices. Before making a purchase, do your research, read on consumer reviews, and make sure you are getting your product from a verified seller to get genuine wood fillers.
