If your wall trim is in desperate need of repair, the best way to fix it is by using a putty knife to apply a thin layer of spackle over the crack. Once the spackle has dried, use a sandpaper to smooth it out. Finally, paint over the spackle with a matching color of paint.

Wall trim is often damaged by moisture and pests. If the damage is severe, you may need to replace the trim. If the damage is minor, you can fix it yourself using a few simple tools and supplies. To fix wall trim: 1. Remove the trim from the wall. 2. Clean the surface of the wall where the trim was attached. 3. Apply a coat of primer to the surface of the wall. 4. Apply a coat of paint to the surface of the wall. 5. Reattach the trim to the wall using nails or screws."
