Introduction

The most difficult task for this repair is removing the crown molding. This can take patience. It is important to go slow and work the crown molding from the wall a little at a time. Going too fast or applying too much pressure at once could potentially cause more damage.

After the molding is removed, the magic happens. Identify any damage that may have already existed and/or that might have occurred during the removal process. Once you have identified what needs repaired, you can add your adhesive to the splits, cracks, or holes. Keep in mind the adhesive has to dry or it will not be effective.

Once the cure time has expired, you can begin to reinstall your molding. If you’ve determined that new material is needed, you need to make some measurements and cuts before continuing. Make sure to measure the top and bottom lengths of the molding since joints can vary. Also, take into consideration the angle at which the cut needs to be made. If possible, it is always good to gauge your new cuts with the molding being replaced. However, careful measurements may be needed if the cuts from the original molding are not within expectation. Once the cuts have been made and the molding fits to standard, you can begin reinstalling.

During the installation process you will need to make sure the molding is in the correct position before securing it to the wall. Make sure the seams between the wall, joints, and ceiling are smooth. This will create a perfect bond between surrounding surfaces after the caulk is applied.

After the caulk has cured, paint can be applied to restore your home or business to its original glory.

  • Be careful when using a saw, as they can cause serious injury.
  • Use a saw to cut the trim.
  • A skill saw is recommended to get a clean, precise cut. A hand saw is doable and may be a cheaper alternative. If a hand saw is used, make sure it is specific for wood cutting to get smooth-edged cuts.

Step 12

  • Secure the molding to the wall using trim nails.
  • The nails need to be long enough to penetrate the molding and the wall. A nail gun is recommended, but a hammer and nail is a doable alternative. Nail placement is recommended for every one to two feet.

  • Smooth and remove excessive caulk.
  • Allow time for the caulk to cure. Once it is cured, the trim is ready to paint. Painting the trim will add a smoothness to the appearance and hide exposed nails or glue marks.

For a project like this, I suggest using any brand of wood glue. You can find these products at Home Depot, Lowes, or other similar stores. It does not matter which brand you buy. Just make sure the product is made for wood, and that you read the instructions on the product that you buy for the required cure times. I hope this helps.
