DIY Rainbow Bedroom Wall

We all love rainbows right? My little girl who just turned 5 has been asking for a rainbow room for a year. Finally, for her fifth birthday, we agreed that we would add a DIY Rainbow wall to her bedroom.

There is so much amazing inspiration out there for rainbow bedroom walls in girls bedrooms including beautiful rainbow wall paper such as this one by Hey Sarah Darling, or this beautiful rainbow trim ceiling one by Lauren Burke, or this rainbow slat wall by my friend Holly.

I was inspired by all of these, and especially the rainbow trim ceiling wall by Lauren. I absolutely loved how she added dimension to a rainbow wall with half round trim and used muted pastels.

Step 1: Choose Rainbow Colours for the Bedroom Wall

I took that inspiration, and first created a mood board for the room featuring colours by Benjamin Moore. In particular, I chose colours from the Regal Select Interior Paint line in an ulti matte finish for the rainbow bedroom wall: Rosy Tan, Rose Bisque, Cinnamon n’ Spice, Light Salmon, Mohair, Blue Lace, and Galt Blue

Step 2: Tape Rainbow onto the wall to create the accent wall

Next, I decided that I wanted the rainbow wall to be centered to the bed I have purchased and after some quick math decided that the width of each colour would be 8 inches. I began to create the rainbow on the wall where the bed would be against. For this part of the project, I used a 2.5 inch paint tape by Frog Tape and that was the gap between the colours. I used a level to lightly draw the lines on to the wall and started with the middle line working my way out. This step is tedious, because you can only draw and tape one line at a time to ensure that your lines are level and that your gaps are even and the width of the tape.

Step 3: Get Painting!

This was honestly the most fun step! Here, I started with the middle colour which ended up being yellow after I moved around some colours. I used high density foam rollers and swapped the foam part out between colours and stored in in aluminum foil to keep the roller from drying. Hot tip: use paper plates to roll the paint in versus paint liners! It is way cheaper on your budget! Once I had completed one coat of paint, I did go in with a second coat of paint. To get clean edges at the ceiling and trim, I used my favourite angled brush by Wooster and I love the clean and finished look this particular brush gives.

Step 4: Paint Trim

I wanted to add some depth to the wall and the stripes. To do so, I used 5/16-in x 5/8-in x 8-ft Pine Wood Half Round Moulding by Metrie to add dimension to the rainbow accent wall. I painted 5 pieces of trim in each colour on a flat surface and trimmed them to size using my Dewalt Compund Miter Saw. You can also use a miter box or a hand saw at the store to cut to exact size as the height of your wall.

Then I used my Ryobi Airstrike 18 gauge Brad Nailer to nail in the pieces onto each colour. The spacing between each trim piece was approximately 1.375 inches and I attempted to keep it consistent. However, since the trim is a wooden trim and given how hot it has been in Ontario this summer, the trim warped ever so slightly between painting, drying, and being subject to temperature changes. Once the trim pieces were nailed in, I filled the holes with Dap Canada Wood Filler, lightly sanded it by hand, and used a craft paint brush to touch up any spots.

Once that was all done, this is what the wall looks like!

Now we are going to work on the rest of the room and hopefully share it for the One Room Challenge Reveal next week! I have already worked on the nightstand for this space using the same colour from the rainbow wall. I can’t wait for it to all come together!
