Step-by-Step Guide

Plastic molding cuts more easily than wood but can melt if you cut too slowly or use the wrong blade. Here's a general process for straight or angled cuts:

1.Measure and Mark: Use a measuring tape to determine the length needed. Add extra for adjustments, especially at corners (e.g., for miter joints). Mark the cut line clearly with a pencil on both edges of the molding for accuracy.

2.Secure the Piece: Clamp the molding to a stable work surface or miter box to prevent slipping. For crown molding, position it at the correct angle (often upside down in a miter saw).

3.Choose Your Cutting Method:For Straight Cuts (Hand Tools): Score along the line with a utility knife a few times to create a groove, then snap or saw through with a hacksaw. This works well for thin trim without power tools.

4.For Angled or Precision Cuts (Power Tools): Use a miter saw or circular saw. Set the angle (e.g., 45° for corners), and cut quickly in one smooth motion to avoid friction heat. Dull blades from woodworking can work well here as they generate less heat on plastic.

5.Smooth the Edges: After cutting, sand any rough spots with 320-grit sandpaper. For an ultra-smooth finish, wipe the edge with acetone to remove dust and polish the surface. Avoid over-sanding to prevent weakening the plastic.

6.Test Fit and Adjust: Dry-fit the piece in place. If needed, make minor tweaks with a utility knife or sandpaper.
