I recently made this bench with MDF and when it came time to paint it, I had trouble getting a smooth finish at the ends of the MDF boards – all the paint was sinking into the MDF leaving holes and a rough finish. Here’s an easy fix I discovered which works like a charm.
Step 1: Brush on Glue Mixture
Dilute some wood glue with a little bit of water and apply it with a brush on the ends.
Step 2: Sand
After the glue is dry, sand it down and repeat step 1 and 2 a couple of times until the surface in smooth.
Step 3: Paint
Your paint will glide on easily and leave a perfectly smooth finish!
