Add Molding to Flat Panel Interior Doors

8 Materials
2 Days

The boring, flat panel interior doors were really dating our home. However, I didn't want to spend the money to replace them all. So, we decided to use plywood to give them the effect of molding.

Cut 1/4" plywood into strips. You'll have to do math to determine the size that you want the boxes to be on each door. Check your math 3 times because we sure did mess it up! Draw a diagram for best results, and then tape the design onto the door to be sure. There's more details on that process in my blog post.

Sand when they are cut to get rid of jagged edges.

Use a nail gun to attach strips to door. Use a level and tape measurer to make sure they look straight and neat.

Use caulk or wood filler to fill all gaps and sand smooth.

Paint. We took our doors outside and sprayed them since we did 8. If I was just doing 1 or 2 I would use a small foam roller and paint them in place.

Re hang and enjoy! We also replaced all our mis-matched knobs with levers.

This was such an upgrade for our home and was done at a fraction of the cost of replacing the doors.

Suggested materials:
  • 1/4" plywood

    How wide did you make the molding pieces?

    The doors with the hardware look beautiful! And the molding was different than your typical panel type doors. It looked good in the picture where you hadn't even painted them yet! LOL

    I would like to know what kind of sprayer that is? I want to buy a small hand held one with containers shown in your picture. I do no have a compressor just need it for smaller craft projects. Any suggestions? BTW I loved the doors they came out so sharp! Thanks for the tip I will try it on one of my plain doors!

    Our interior doors are construction grade pre-stained. How would we go about painting those after the design overlay is attached? And would the liquid nails, or something similar, hold well enough?

      Would chalk paint work? Idk. Maybe someone with more experience using it would know. You could also stain it all with gel stain - it’s the chalk paint of the stain world. Almost no prep.
