Wood Putty vs. Wood Filler

When you are building a project using wood, there will invariably be instances where you will see either the top of the screw head, or a small hole within the wood where you had to use a nail. When you have a finished project, there is nothing that will distract from it more than when you have open holes within the wood pieces you are using. There are a few different ways in which you can help eliminate the holes within the projects; the two main products used are wood putty and wood filler.How do you know which one is better to use for the project you are working on? Is there a significant difference between the two, and will those differences have a big impact upon how your project will look when it is complete? Let’s take a look at the characteristics of each product category, as well as providing reviews within each category. We’ll then provide a comparison table, so you can easily tell the differences between the various products.

Wood Putty

This product can be comprised of a few different kinds of materials, but the typical ingredient found within Wood Putty is wood dust. This dust is very fine, and is easy to manipulate as a great compound to help fill in all the gaps of any hold found within the project. In addition to dust, the putty is helped kept together by using a binding agent as well as a thinner.
Wood Putty is also available in a variety of colors, which makes this filling agent a very versatile solution to your needs. Especially if you are attempting to fill the holes in after you have stained the wood, which is not recommended. But, if that is the situation you find yourself in, then you should be able to find a color which matches the stain color you have chosen.
When using Wood Putty, it is best to apply the putty before you stain the wood. This way, you can apply the wood putty and then sand it down properly and have it blend in to the wood better. If you wait to apply the wood putty until after you have stained the wood, your color will be close, but it’ll be nearly impossible to exactly match the color of the stain you choose. Even if you have the same brand of stain and wood putty, they are made out of different materials and therefore will not match exactly.

Wood Filler

A wood filler is typically made up of three different components, which include some form of a solvent, a bulking agent and an agent which will bind it all together. A wood filler can be used to fill holes, but it is actually better used to fill pores within the wood surface to create a smooth and clean surface. The wood filler is a great product to use for wood surfaces which are very porous, like an oak, walnut or an ash wood material.
If you have a wood surface which has a very tight surface which does not have many pores, than going with a wood filler is not the best option. Using a wood filler will cause your surface to be uneven, and if you have to sand it down, you could do more damage to the wood by digging down deeper into the wood. You should sand the surface lightly before applying any wood filler, so it can reach deep into the pores as possible.
The wood filler acts as a way to cover any blemishes within the surface of the wood. When you apply the wood filler, you can brush it on both with the grain, and against the grain. Once it has dried, it can be brushed off using something besides sandpaper. This is typically a microfiber rag, or some burlap which will help get the excess off without damaging the wood any further. You should not use steel wool or any other harsh or abrasive finishing tool, as you run the risk of damaging the wood further than what it was initially.
