Different types of wood fillers:

1. Cellulose-based or water-based wood filler:

It is sold in either a powdered form or paste form. It is one of the most affordable and cost-effective wood fillers, easily available in hardware stores and online. It is very user friendly and good for beginners. It has a long shelf life. The wood surface after its application is easily paintable and stainable. The wood surface is also reasonably tough after its application.

A water-based wood filler has gypsum in it. Because it is made out of natural wood fibres, it has minimum odour. It cannot emit any volatile organic compound.

A water-based wood filler is not waterproof and it is not weatherproof so it is better suitable for indoor use. A cellulose-based or water-based wood filler can dry within only 15 minutes. Its thickness can be manipulated where a thin layer is needed. If you intend to remove the cellulose-based or water-based wood filler from your furniture, you can do it within a couple of minutes by simply using some soapy water alone.

2. Epoxy-based or solvent-based wood filler:

This filler is sold in two different parts that need to be mixed very well before application. Epoxy-based wood filler can also be used as an alternative of wood glue to paste two different surfaces on to each other. But it is not ready to use like other wood fillers so it will take a few more minutes in preparation.

Epoxy-based wood fillers are waterproof and weatherproof so they are ideal for outdoor use. It emits high levels of volatile organic content and is characterized by a strong unpleasant smell. This wood filler takes longer to dry as opposed to its water-based counterparts as you might have to wait for up to an hour.

Removing this wood filler needs you to use turpentine or acetone. It is resistant to water, extreme heat, rot, cold and humidity.

3. Latex or vinyl or solvent-based wood filler:

This type of filler is the fastest drying wood filler. But it is not crack proof if you apply it in thick layers. This type of wood filler is very easy to mould and shape to flatten the surfaces that are not even. This wood filler is waterproof and weatherproof so it is ideal for outdoor use.

It comes in the ready-to-use form and is extremely user-friendly. It does not stain easily.

What is the difference between wood filler and wood putty?

Wood putty is made up of epoxy, fibreglass or Polyurethane. While wood fillers are made up of natural wood fibres or sawdust. Although both of them are used to fill the gaps or cracks in the wooden objects, they are different in texture and hardness.

Wood putty is waterproof, weatherproof, stain proof, crack-proof and ideal for outdoor use. Wood putty does not shrink and it is easily paintable. While a wood filler is infused with pigments to match a certain type of wood and is intended to be coated with a clear finish.

Some wood fillers are not flexible, and they can crack when the wood expands and contracts under the direct sunshine. Wood putty is for big holes. Because it hardens due to a chemical reaction and not as a result of its contact with air, you can put it into very deep holes, and it will be rock hard in just 10 minutes.

Wood putty is a very good adhesive, so if you have 2 pieces of wood that you would like to link together, this is a good choice. The wood filler is for shallow holes only, i.e., 1/4″ or less. Because it dries due to interaction with air, the more shallow the hole, the quicker it will dry.

This putty is not water-soluble. It is fully waterproof and weatherproof. It works best when a coat of finish is applied after the putty is rubbed into cracks and gaps in wood flooring or planks. It is possible to use it when a coat of finish will not be applied, but, with no finish to protect it and hold it in, some amount of the putty will come out over time. It expands and contracts with changes in temperature and humidity so it will never crack or shrink when used outdoors under direct sunshine.

If you have a wooden floor indoors, and gaps in the floor bother you, just expect to periodically have to putty those cracks. This putty is very easy to use. Take a minute or two to fill cracks as they appear, or thoroughly putty all cracks before re-coating the floor with a wood finish. One of the drawbacks of this product is that it comes in a very small package and you will have to buy multiple packages for a large project.
