Change your room in an afternoon with a DIY painted arch accent wall and update a piece of furniture in the same color for a big impact!

I’ve said it before and I’ll say it again, the power of paint is magical! When I found out about the KILZ® Accent Wall Challenge, I jumped on the chance to create a new study area for our teenage son. His room has been one of the slower evolving spaces in our new house, and I still wanted to address his desk area.

Decide on which wall you want to feature. I love choosing a wall that you see right away when walking into a room. It will give you the biggest bang for your buck, so to speak. I decided on the far wall in our son’s room where his desk already was. After you decide on your spot, clear the space to prep for paint.

Select a color. Here are some tips to make this step easier.

  1. Create a tone on tone effect by picking a color that is a couple of shades darker or tints lighter than your wall color.
  2. Refer to a color wheel to see what the complementary color is across from your wall color.
  3. Select an accent color from your existing decor and furniture for a neutral wall.

I’m all about tone on tone these days, so I decided on a darker blue to go on the light blue walls. The color of KILZ Complete Coat® Paint is called “Virtue” and almost looks like a teal. It looks great with decor that is already in the room.

Draw an arch using the old-school method for a circle.

Make sure the wall is cleared, wiped down, and any holes are filled with spackle. Don’t forget to remove your outlet covers. Pick a point in the middle of the wall you are going to paint. The distance from the middle to the edge is how long your string for a guide should be. Hold the string in place with a tac and tie a pencil to the other end near the lead. Draw a semi-circle.

Next you’ll want to tape off the edges and trim. Use a level for perfectly straight lines.

I used KILZ 2® ALL-PURPOSE Primer which blocks medium stains including minor water stains, rust, grease, ink, pencil, and felt marker. Enhanced hiding makes it ideal for changing colors and helps lessen the number of coats of paint required. It also can be used on multiple surfaces which made it perfect for a prime coat on the desk.

Use an angle brush to carefully and slowly outline the top of the arch, around the edges, and outlet areas before filling it in with the roller brush.

Paint the piece of furniture the same color as the wall. The paint dries quickly to the touch but I always suggest not place anything on the furniture for a few days to let it completely cure.
