How To Use Wood Filler for Large Gaps —A Step by Step Guide

Wood filler is a versatile product that can be used to fill in both large and small gaps. It is an easy way to make your woodworking project look like it was professionally done.

When you have a gap in wood that is too large to simply glue together, you need to use a wood filler. To use wood filler, start by cleaning out the gap you want to fill. Then, apply the wood filler to the gap, using a putty knife. Once the wood filler is in place, use a wet rag to smooth it out. Allow the wood filler to dry for the amount of time specified on the product’s packaging.

Wood fillers are beneficial because they can be sanded down once dry and also, they can be stained or painted to match the surrounding wood.

What Is a Wood Filler?

A wood filler is a thick substance that can be used to fill in cracks and fix holes. It is a putty-like substance that hardens when it dries, making it perfect for filling in gaps.

Uses Of Wood Filler

  1. Wood filler can be used to fill in cracks, holes, and other imperfections in wood.
  2. It can also be used to repair furniture and other woodworking projects.
  3. It is also a good way to change the color of wood.

Types Of Wood Fillers

There are three types of wood filler:

1. Solid Wood Filler

This type can be sanded and is good for large to medium-sized holes.  It comes in a tube or tub, which makes it easy to apply to your project. They usually come with more color options than other fillers do as well.

2. Latex-Based Wood Filler

This filler is easy to use and dries quickly. It also comes in a variety of colors, so you can find the perfect one for your project. However, it does not sand well, so it’s not ideal for larger holes.

3. Epoxy-Based Wood Filler

This type of wood filler is the most durable and can be used for both small and large holes. It dries slowly, so you have plenty of time to work with it.
