After the open time, the substance will turn into a gel-type mixture and not be watery anymore. Most epoxy products have an open time of 5 to 60 minutes. It also depends on how big or small cracks you need to fill in.
If you have larger cracks to fix, you might need a longer open time for the epoxy since it will require you to use more. Generally, it is better to have a longer open time. This will give you more time to work on the epoxy and fix the damages to the wood.
3. Tint the epoxy
Tinting the epoxy is not required. It depends if you want it to be tinted or not. However, most woodworkers want to have the epoxy matching the color of the wood they work on. If you are conscious of the wood cracks and want them to vanish, it is highly recommended to have your epoxy mixture colored as the wood you have.
4. Filling cracks in the wood
This step is the important part of fixing your wood with epoxy. When you are ready with your tools and products to use, all you need to do is apply them.

- If it does, you need masking tape to cover the end part of the wood so the epoxy won’t flow on the other side.
- Pour the substance into the cracks or holes of the wood. You need to fill it in until it reaches the top or feels it is filled in.
- Wait for 24 hours to cure the epoxy substance. This is a vital part of the project, and you need to cure the epoxy to restore the wood.
5. Sand the fills level
After curing the epoxy on your wood, you will need to level it to the surface of the wood. It would be the best option to have sandpaper or sanding block for this step. You should check your sandpaper once in a while to avoid the epoxy lumping on it because this can cause it not to level the wood and epoxy evenly.
Continue sanding until you feel that it is even with the surrounding surface of the wood.
6. Finishing the surface
The last thing to do is to polish the fill and the wood. You can also repaint the surface if you want. If you want to remain it as is, you can use oil or a wood varnish for your finishing touches. This results in a shiny finish of wood furniture or items in your house, making it look brand-new.
