Wood shims are thin, tapered pieces of wood used to fill gaps or level surfaces. Here's a breakdown of how to use them properly:
-
Identify the Gap or Uneven Area: Determine where you need to use the shim. This could be under a cabinet, between a door frame and a wall, or any other place where you need to create a level or stable surface.
-
Position the Shim(s): Insert the shim into the gap. Typically, you'll want the thicker end of the shim to go in first if you need to fill a larger space.
-
Achieve Proper Contact: According to the video, continue pushing or adjusting the shim until you achieve the same positive contact on both sides of the gap. This means ensuring the shim is making solid contact with both surfaces.
-
Secure the Shim(s): Once you've achieved the desired level or fill, you can secure the shim in place.
- For Permanent Installations: Use construction adhesive or nails/screws to permanently secure the shim.
- For Temporary Installations (or reusable shims): You may not need to secure them if the weight of the object (like a cabinet) holds them in place.
-
Trim Excess (Optional): If the shim is protruding beyond the surface, you can trim the excess with a utility knife or saw. Score the shim first with a utility knife for a cleaner break.
-
Reusing Shims: The video suggests that you can remove and reuse shims after securing the object with screws.
In essence, the goal is to create a solid, level, and stable base by strategically placing shims to fill gaps or correct unevenness.
