Use this Green Print as a guide, but feel free to be creative with your design! Note: the size of your wall and the moulding used will affect the placement of the moulding.

How to install:

Step 1: Choose your wall and moulding
Identify the wall you will be working on and determine the style of moulding that would best fit the space.
Step 2: Measure everything and determine the spacing.
Measure the wall height and width, and make sure you take into consideration outlets, windows and light switches. This will help you get a feel for the board footage needed and where to cut your moulding. We recommend adding 10-15% board feet for waste and board cuts.
Step 3: Mark it up
Mark the wall where moulding will be placed to get a visual of how the moulding will look. Using a laser level can help you project lines onto your wall. 
Step 4: Cut your moulding
Cut the moulding needed for your wall. We cut each piece at a 45 degree angle. 
Step 5: Apply the moulding to your wall
Use thin plywood to cover the entire wall to give it that raw wood look. When installing your moulding try to cover up the seams from the plywood with your moulding. We recommend using 2” finishing nails and a nail gun to secure the moulding profile for long term wear and tear. Keep in mind you’re going to have to finish the moulding with caulking and wood filler, so the fewer nails, the better for less work on the finishing process.
Step 6: Fill in the gaps
Use plastic wood filler/Caulk – Almond for all the seams to fill in any gaps. 
You should also apply putty to all of the nail holes.
Step 7: Enjoy your beautiful accent wall!

Helpful tips when creating an accent wall

  • Choose a balanced, unobstructed wall that stands out. 
  • Choose rooms or spaces where you want to make an impact. Bedrooms, living rooms and entryways are great spaces to create a custom look. Select spaces where guests will see it, or where you spend a good amount of your time.
  • Bold colors really make a statement. Dark greens, grey, black and blue are currently in. 
  • White accent walls make a statement without being too bold. 
  • Try to pick a style of accent wall that complements the look of your home and room; just because you like a modern style wall doesn’t mean it’s the best pick for a colonial style room.
  • Go in with a plan and draw out your design before beginning.
  • Find 2-3 moulding profiles that you think will achieve the look you’re going for. Then, take each sample and place it on the wall to see which you like the best.
  • Create a jig if you have to repeat a cut. This will save time and help with consistency.
  • Use hot glue to apply moulding first so that you can adjust the moulding if needed. Then use finishing nails to secure the moulding.
  • Rent a nail gun, use your own or use an adhesive.
  • Once everything is in place, apply more nails to ensure it is long lasting. 
  • Use putty to the nail holes rather than caulking for a better finish.
  • If using a paint sprayer, keep 1.5 to 2” of space between you and the wall for an even application.
  • Take your time in the finishing stage. The little details when you finish will make the wall look more polished. 
  • We estimate that creating an accent on a 12′ x 8′ wall can cost around $200. This includes paint, moulding, tool rentals and other materials. You can save money by using tools from your home or borrowing from friends.
