Painting can be quite fun, the furniture needs to be moved to other area to make the area available for painting. This is the reason why this MDF (Medium-density fiberboard baseboard was damage. MDF is has many uses specially in California were there is no straight wall. MDF is made of sawdust and glue and cured with pressure to form any shape needed. MDF baseboards cost is three quarter less its counterpart the wood baseboard or wood trim. 

This post shows the five steps to repair this baseboard.

Step 1: Fig.1 shows the damage to the MDF baseboards. Tape the area for repairing and painting. Fig.2 shows some of the painting tools needed to protect the area around the baseboard damage.

Step 2: Once the area is masked with painter tape, the repairs start. Look at the damage, there are three choices. The first and easiest choice is to repair the damage baseboard. The second choice is cut out a small piece and replace it with another piece of baseboard. The last choice is to remove the entire baseboard for that wall and replace the a new piece. For this project repairing was the best choice. Fig.3 shows the damage baseboard and fig.4 shows the first step is to press the baseboard against itself.

Step 3: Fig.5 shows the Titebond® glue placed in a small glass container. Fig.6 shows to use a small brush or your fingers and apply a little amount (5 milliliters = 0.1691 ounces) of glue on the damaged area. Start to press the baseboard damage back together to form like the rest of the baseboard.

Step 4: Fig.7 shows that after the glue has dried, use caulking or paintable silicone to seal the area from moisture. Fig.8 shows a tube of Dynaflex® 230 silicone but any caulking will work for this project. Dynaflex® 230 was available from a prior job.

Step 5: After the caulking has dried, use 120 grit sandpaper to remove the rough edges. Fig.9 shows the next step is to seal the area with Kilz® Oil  Primer. It does not have to be an oil primer any primer will do the job. I chose Kilz® Oil spray primer because it was a left over from a prior job. Fig.10 shows the primer has dried and the final step of painting the baseboard to match.
