The One Thing Your Accent Wall is Missing — and the Easy, Under-$20 DIY Fix

If you’re looking to make a big statement without investing a lot of time or money, accent walls are a sure bet. A bright color, bold pattern, or even a cool texture can all turn a plain wall into floor-to-ceiling artwork. Using painter’s tape (if you’re painting) or a craft knife (if you’re wallpapering) can help you get clean edges, but there’s a final step that can take your accent wall from good to great.

As TikToker @creativechronicles shows, the secret to a seriously professional looking finish is a little bit of corner molding to help hide sometimes-scrappy edges and ensure a seamless transition between your accent wall and the rest of your space.

In the TikTok video shown above, this DIYer shows exactly what you’ll need to do to finish off your corners with trim. First, you’ll need to make sure you have the right material; look for outside corner moulding in pine (a low-cost, paintable wood). The trim shouldn’t run you more than about $20 or $25 for two corners.

Start by painting your trim to match the color of one of the adjoining walls so it will blend in more easily. Then, if you need to join multiple pieces on your wall, miter the edges of each at 45-degree angles; once filled and painted, these seams will be a lot less noticeable than straight ones. You don’t even need a saw to pull off this job — miter shears will do the trick for this small trim.

After nailing everything up, alternating the sides where you place the nails, fill any holes with wood filler and let dry. Touch up with your chosen paint color and that’s it! The added edge won’t be a statement maker, but it will allow your accent wall to shine with the new professional finish.
