Splintered wood is unattractive and also a little dangerous due to the sharpness of the splinters. It is also leaves the wood vulnerable to further splintering and moisture damage. Once repaired, the splintered wood is just as strong as it originally was and can even blend in with the rest of the wood.

Step 1

Cut any large, ragged splinters off the wood using a small saw or sharp knife. If there are only a few splinters, you can break them off.

Step 2

Sand the splintered area smooth using 60-grit sandpaper. If the project needs a smooth surface, continue sanding with finer and finer grades of sandpaper until you reach 220-grit. This is important if the splintered area is on a surface that is used frequently, such as a desk.

Step 3

Fill the area with wood putty using a putty knife. Let the putty dry according to package instructions or overnight.

Step 4

Sand the wood putty smooth with 100-grit sandpaper. Dust with a tack cloth.
