DIY wall treatments – Sincerely, Sara D. DIY

I am obsessed with older houses because they have so much character and charm. Many of these houses have unique wall treatments and I have tried to repeat these wall treatments in our house. I have summarized all of my favorite DIY wall treatments (and tutorials) for you.

Before we move on to projects, please note that I am not a professional. However, I love the character that the wall treatments give our home and I enjoy the DIY process – even if they are not perfect.

If you paint these wall treatments, I would also recommend painting the entire wall in the same color – including the bottom skirting board. For information on how to easily paint baseboards on carpets, go to this tutorial.


DIY wall treatments

This square paneled wall was one of the first wall treatments we added to our home and is one of my favorites.

As with any wall treatment, it is a good idea to measure the room and outline a plan.

In the end, I also drew the plan on the wall, which was a great idea as I resized the squares.

For most of the wall treatment, we used a primed MDF molding of 0.688 x 3 x 8 feet in size (I added a wider piece at the top and adjusted some later) and pushed the bottom part to the baseboard.

We used a hammer and nails instead of a nail gun. After this project, we bought a nail gun, and that makes the process so much easier. You are worth the investment.

We caulked and painted the entire wall and lived with it for several years.

I later added cove molding to the inside of the squares, and it was worth the extra effort.

I also added a thin piece above to add a little more dimension, and painted the wall in Benjamin Moore’s Storm Cloud Gray.

Classic board and latte

Classic boards and laths are timeless and a relatively simple wall treatment. I created this solo one afternoon.


  • (9) 5 1/2 “x 8” primed MDF board
  • (6) 2 1/2 “x 8” primed MDF board
  • (2) 3 1/2 “x 8” primed MDF board
  • Sandpaper
  • Sealing
  • Wood filler
  • Nail gun
  • Chop saw
  • level
  • colour

For this project, I started and the floor and moved up. I added 3 1/2 “x 8” primed MDF board to the base (just above the base board).

Once the bottom part is on top, lay out the 5 1/2 “x 8” boards and find out how far the parts need to be placed.

The top is a 2 1/2 “x 8” plate. Once this is done (use a level to make sure everything is level), add the larger (5 1/2 “x 8”) boards. Start in the middle and then center a bit between the middle of the wall and the corner on the right. Do the same with the left side.

Add another 2 1/2 ″ piece that was added at the top (or you can use a thicker board instead of the two smaller boards – I worked with what I had on hand). Add a piece of the 2 1/2 “x 8” plate to the end of the wall. I flipped it over to create a finished edge (or edge).

To see a more detailed tutorial for boards and slats, you can see the original post HERE.


This elegant wall treatment is a bit more ambitious than the other wall treatments I share, but I was able to create it solo – which means it is doable!

Accessories for elegant wall treatment

  • (4) 4.5 “corner blocks
  • (20) 1 3/8 “x 8 foot primed base cap molding
  • (15) 4.4 “x 8 feet of primed corner blocks square edge
  • (8) Sealing tube plus some wooden spatula
  • (1) Gallon Valspar Reserve Paint in Night View.

You’ll also need a simple miter saw, nail gun, and compressor.

If you’d like to recreate this look, I would recommend going to my full tutorial HERE. However, here is a quick overview:

Start at the top of the wall and work your way down. Cut a piece of the square edge of the corner block and make sure the top is flat as you try to keep it as close to the ceiling as possible.

Cut off parts of the corner caps and create a frame around the corner blocks. Next, cut parts of the square edge of the corner block to fit around the framed corner blocks.

Add a piece of the square edge of the corner block at the bottom of the wall above the existing cladding, then cut off the square edge of the corner block to frame the bottom of the wall.

Finally frame the rest of the lower part with the square block edge and frame the inside with the cladding cap.


This decorative wall molding is a finer wall treatment and gives our landing on the upper floor a lot of character.


The complete, detailed tutorial can be found HERE.

First measure the wall and create a plan for the decorative molding. I used grid paper that was very helpful for measurements. Once I had a plan and dimensions, I put the plan on the wall and pulled out all of my frames.

With a 1.25-inch trim, I mitered and framed different sizes of decorative molded parts. Use a chop saw to cut the panel (45 degree angle), and a nail gun is very helpful when gluing the frames to the wall. Complete with sealing and painting!
