How to fix a crack on wood

1. Examine wood that will be treated closely

The first thing that you must do is to examine wood closely to find out exactly where you need to place the epoxy product. There are many ways to do this. One you can visually inspect wood to detect cracks and splits, you can use our hands to feel for uneven areas where cracks and splits are likely to form and the use of lighting, once you have found cracks and imperfections, use a mark to remember where these cracks are. Use a pencil or an erasable material to mark cracks and splits well.

2. Prepare all the materials needed for the project

You need all the materials that you will need for the project in a caddie or on a table next to you when you work. All the materials that you might use for this project are available in a hardware store with the exception of WoodFill since this purchased only exclusively from the product’s official website.

3. Select the ideal WoodFill epoxy for your project

WoodFill comes in six colors and even in white. The best way to find out if a color works with the type of wood is to take the tube and to compare it against the wooden surface. Most of the time it is hard to look for the actual color that matches with wood and this is why WoodFill epoxy products can be combined together to create darker or lighter wood shades. This also allows you to look for the ideal color match to further enhance the beauty of wooden furniture. The right color also hides other flaws and imperfections that can affect the value of wood.

4. Open the tube of WoodFill

Now that you have decided which color or colors of epoxy to use, it’s time to use these two on the crack or split on wood. This epoxy comes in a glass tube. It looks completely different from other epoxy products that mostly come in aluminum tubes.

Open the tube, remove the epoxy material and decide how much you will use. Use a blade or a cutter to cut the amount of epoxy that you wish to use for your project.

5. Prepare the epoxy

Check the WoodFill epoxy composition. As you can see, the epoxy material and the stain are rolled together. All you need to do is to mix these together by softly and slowly kneading these together. Use your hands to continue mixing and kneading until you have an even consistency. You will know you are ready to apply epoxy material when you have an even color of epoxy in your hands.

6. Apply the epoxy on wood

Use a sander with 100 grit sanding paper to finish the treated area. Make several passes on the surface of the wood or wooden furniture that you are treating. And to further enhance the appearance of wood, use sand paper and manually remove imperfections. Just like using a sander, make several passes on the wood so you can completely remove any epoxy and to avoid lumps and imperfections on the area that is being treated. If you are working on a larger area, make sure to clamp the wooden piece securely as you work.

8. Apply finish on wood

Using a finish or varnish on wood is according to your preference. There are many advantages of using finish though. With a varnish or finish, you will be able to admire closely the beauty of wood, you will be able to keep insects and other burrowing creatures from destroying wood and most of all, you can deter the formation of moisture which could weaken wood when you use varnish.

Apply just a small amount in an old rag or cloth and then apply on the surface. Use one coat of varnish, let this dry, and then apply another coat for good measure.
