Steps In Repairing MDF Baseboard

If your MDF hasn’t crumbled, warped, or separated from itself, you may be able to repair it. However, items exposed to water for a long time may not be possible to repair.

Below are the steps in repairing an MDF baseboard that sustained water damage. 


Step #1. Sand the baseboard

Thoroughly sand the baseboard using 80-grit sandpaper attached to a hand block. Strip all the paint if the water damage covers the length of the baseboard, but if the damage is seen only in small areas, you may sand the affected area only. 


Step #2. Prepare the resin glue

Mix a powdered resin wood glue with water according to the instructions stated on the label. Fill the separations and cracks with the resin glue using a paintbrush, and let the glue dry overnight. 


Step #3. Fill all the damaged areas

Fill the remaining pits and gouges where the resin glue shrank. Use wood filler and a putty knife, and sand the surface using 100-grit sandpaper as soon as the putty is dry.


Step #4. Sand the shallow curves

Fold the 100-grit sandpaper into thirds, and use it to replicate lines in the molding. Slide the sandpaper’s edge along existing lines to create new lines, and don’t forget to sand the shallow curves. 


Step #5. Apply the sealant

Apply the sealant to the sanded areas using a brush and put two coats of water-resistant paint on the MDF’s surface to match the existing color.
