What We Learned Putting MDF Board And Batten In A Bathroom

There are thousands of tutorials about adding board-and-batten walls to your home to add style. If you are considering adding board-and-batten to your bathroom walls, make sure you read our tips before starting.

#1 MDF Can Work, But Be Careful

If we had done things differently, we would have used moisture-resistant MDF or PVC boards for our trim. MDF is not great for bathrooms, kitchens, or other areas that are meant to get wet.

With that being said, pre-primed MDF would have also been a better choice and would have stopped us from having to do #3 on this list.

#2 Cutting Your Own Strips Is Cheaper

By ripping boards from a large MDF sheet, we were able to create this design for under $50. If you have the tools and ability, cutting the strips is not that hard and will save you money.

#3 Use An Oil-Based Primer If Using Regular MDF

In the ideal world, you would use an oil-based primer on your cut boards in an open-air environment. By painting 2 – 3 coats of primer on all edges, you would seal the MDF.

Due to time constraints, we put all the parts on the wall for the area with the hooks and then primed. Because we did that, it took longer to prime.

We set up a painting station for two-thirds of the board-and-batten wall. From our understanding, the edges of the MDF are the most susceptible to moisture. Making sure those strips are primed well will hopefully prevent you (and us) from having any moisture-related problems.

#4 Make The Spacing Work For Your Space

Take time to plan out your wall. You can draw sketches or even measure right on your wall to see your layout. If you are doing the wall all around a space, you can slightly change the distance to make it work.

For example, our hook wall has vertical boards 1.5″ further apart than the area behind the toilet. The only way people will know is if they bring a ruler into our bathroom (and that would just be weird).

#5 Caulking Is A Pain-But Totally Worth It

I filled all the nail holes with wood putty and used a paintable caulk meant to help prevent mold in bathrooms and white environments.

I found it easiest to caulk the inside rectangle before wiping the seam with a damp and soapy finger.

TIP—Pay attention to the corners. It is very easy to have too much caulk. We get it: This is easier said than done.

#6 Use A High-Quality Paint

Once your oil-based primer dries, you can use a high-quality water-based paint (like Urethane Trim Enamel). We painted ours with a 2″ angled brush and a small foam roller.

#7 MDF Dust Stinks

When cutting and sanding MDF, you will create a lot of dust. Working outside with the cut boards for sanding, priming, and painting was easier. Wear a mask and use your shop-vac ofter to clean up.

We did not end up sealing all the edges with primer along the floor on one wall. To help make the wall last, we placed a small caulk line under the baseboard so that water could not seep in.

#8 Decide If You Need Construction Adhesive

Putting adhesive behind your boards before nailing them up will destroy your walls when you take them down.

However, you also have to decide the weight of the hanging items, etc. For our DIY board-and-batten wall, my husband decided to use construction adhesive behind the top boards before using a nail gun to attach them to the walls.

#9 Smooth Walls Are Great

If your walls are smooth, there really isn’t a need for a backboard. My husband and I debated this but ultimately decided to work with the wall’s texture. I am happy we did not choose to add extra material to the walls. I don’t think it would have made a big difference in the final appearance.
