How long does it take to build an accent wall?
For a standard 12-foot wall, expect to spend about a day and a half. The first morning is for measuring and cutting, and the afternoon is for nailing, filling holes, and caulking. The second day is just sanding your filler and rolling on two coats of paint. The biggest mistake beginners make is rushing the caulk — let it dry completely before you paint, or your brush will drag the wet caulk and leave a messy texture.
What material should I use?
If you are painting your wall, and it isn't in a wet bathroom, primed MDF is usually the best choice. It is smooth, affordable, and doesn't have wood grain that will show through your paint. If your wall is in a high-traffic hallway where it might get bumped, poplar is much stronger and won't dent like MDF. Only use pine if you plan to stain — the knots in pine will eventually bleed through regular paint.
What tools do I need?
You only need a few basics: a miter saw, a brad nailer, a 4-foot level, a tape measure, a caulking gun, and a stud finder. If you don't own a saw or a nailer, you can rent them from a hardware store for less than the cost of the wood. A laser level is also incredibly helpful for getting your lines perfectly straight.
How do I measure my wall?
Measure the width and height in inches. Because houses settle, measure the width at the top, the middle, and the bottom of the wall, and use the smallest number. Do the same for the height on the left and right sides. If you have a window, just measure from the edge of the wall to the window trim.
Do I need to take my baseboards off?
You have three options. Leave them on: it's the fastest way, but the bottom of your vertical boards will stick out a bit over the baseboard. Remove them: take the baseboard off, install a flat bottom board for your wall design, and put the baseboard back on over it, which gives a very clean, professional look. Or replace them entirely: remove the baseboards and use a flat piece of wood as your new, modern baseboard.
What do I do about outlets or air vents?
Always try to keep outlets inside the empty gaps of your design. If your layout puts a board directly over an outlet, don't try to cut the wood around it — it almost never looks right. Just tweak your layout spacing in the app by an inch or two until the board clears the outlet completely.
Do I have to nail into wall studs?
No. Decorative trim is very lightweight. A bead of construction adhesive on the back of the wood, combined with small brad nails shot directly into the drywall, will hold it perfectly. The only time you really need to hit a stud is if you are adding a top ledge that will hold heavy picture frames.
How much paint do I need?
One gallon is plenty for a standard accent wall, covering two full coats with some left over. Adding trim doesn't actually add that much surface area to paint.
What does it cost in materials?
A typical accent wall usually costs between $80 and $200, depending on the size and whether you use MDF or real wood. Don't forget to budget for a tube of construction adhesive, paintable caulk, wood filler, and paint.
