For the outlet holes, drill a hole with a drill bit into the corner and then use your jigsaw to cut it out (you can also use jigsaw for window too). I measured where the cuts should be, drew it on my board, and then used a circular saw to cut the window holes. STEP 3: Cut the window and outlet holes on your backer board. ****If you have smooth walls, SKIP TO STEP 5***** STEP 2: NOW you can go and buy your materials! Have Home Depot/Lowes cut the large backer board, but leave the trim pieces for home with your saw because you will want them to be exact (and every space is slightly different).

OR, you could just plan your space already knowing that you want your trim batten pieces to fit with the 48 in width backer board. Once you’ve drawn out your trim batten pieces, you will then (IF you have textured walls) know if you need to have the backer board cut down slightly so all the seams are covered. *Helpful tip: This website can help you calculate where your boards should go!.Keep spacing between trim batten boards the same.Remember the REAL dimensions of a 1x2in board is actually 3/4 x 1.5 in, a 1×3 is 3/4 x 2.5 in….Don’t forget a trim piece to go on the very left, right, top and bottom of your wall to frame out the space, if you’d like.A few things to consider when drawing out your wall: This is super important because in the end you will want to have your backer boards’ seams all covered by the trim pieces. STEP 1: Before purchasing anything, you need to draw out your wall and measure where all of your batten trim boards will go. You could also get a thin plywood, but this was cheapest! It is dark brown and one side is super smooth.

*Helpful tip: before purchasing boards, always hold them to your eye and look down them to make sure they are straight!įor my backerboard (only if you have textured walls and want a smooth look) I got a 4×8 sheet of the Eucaboard at Home Depot (see pic of tag below).

Other options would have been to get just normal or select pine boards, or mdf boards. I wanted a thinner look for my batten so I chose a 1×2 fingerjoint pine (see image below).
