Easy DIY Faux Mantel Beam

Hey guys! Today I am going to share how to make this DIY faux wooden beam for your mantle. Its an EASY DIY that only requires only two tools and the best thing is, you don’t need any wood working experience to get the job done. So lets get started, who wants to build a mantel? 

What you will need:

(supplies will depend on the dimensions  of your mantel) 

  1. (2) 1x8x10 ft Premium Kiln-Dried Square Edge Whitewood Common Board 
  2. Stain (optionl). For mine I mixed a custom stain color of Early American and  Weathered Oak
  3. Nail gun OR Hammer 
  4.  Brad Nails OR regular nails 
  5. Liquid nails (optional, be sure to also grab a caulk gun if you don’t already have one) 

Step 1: 

Measure the top part of existing mantel, mine was 74.5 inches long. Then measure the sides of your mantel from wall to  the front of the mantel. Be sure you don’t skip this step as a 1x8x10  may not work for you. Measuring this will let you know how wide your wood needs to be. Mine measured to be 8.5 inches which means I need the width of my wood to be at least 8.5 inches, this is why I got the 10 inch common board pieces. This left me with about 2 inches in front but I was ok with that because I wanted my front piece of wood to be 10 inches, not 8.5. Be sure to do all the measuring BEFORE you go buy your wood so that you get the correct size. Also, you’ll want to know this information before you buy your wood  if you DO NOT HAVE A SAW AT HOME (you’ll find out why in step number 2)

Step 2: 

Cut your two pieces off whitewood common board to the lengths you measured for the top and front part of your faux wooden beam. Then cut your two side pieces of wood. If you do not have a saw at home, thats ok, Home Depot and Lowes will both cut your wood for you. Home Depot will always do it for free, Lowes charges you 25 cents after two cuts. Some times you can get lucky, and Lowes wont charge you. At this step, you should have a total of 4 pieces of wood. Two of them should be the smaller side pieces, and the other two should be the longer top and front pieces. 

Step 3: (optional) 

Stain your wood! I like to stain each piece before putting it together that way all the nooks and crannies are covered. To achieve the look thats photographed above, start  LIGHTLY staining your wood pieces with the Early American stain. What I like to do, is lightly stain using an old sock or rag then immediately wipe right off.  This gives you a nice light look and also allows for your piece to dry a lot quicker. The longer you let it sit, the darker your color will be, so keep that in mind while staining. After you cover your whole piece in Early American, go over it a second time but with Weathered Oak. This will take out the orangish tones that the Early American color leaves behind. Personally, this is my FAVORITE stain combo but it may not be yours. Find a stain color you like and stain away. 

Step 4: (optional) 

This step is optional but highly recommended if your mantel is hallow like mine was. Grab your liquid nails, apply a generous amount onto the top of your mantel then place your top piece of wood on top of the liquid nails. In the next step you will be nailing your top wood piece to your mantel, however, if you have a hallow mantel this will help secure the top piece since you wont be nailing into any studs. So for this step, decide what is best for your project and if you decide to skip it, then move to step 5. 

Step 5: 

Use your nail gun and brad nails OR hammer and wood nails, to nail the top part of your wood to the top part of your existing mantel. I used a nail gun and nailed all the way across the mantel on the back piece of the wood closest to the wall.

Step 6:  

Place your second large wood piece in front of your existing mantel and line it ip with the top piece of wood you just nailed in. Once its lined up evenly, use your nail gun/hammer to secure the two pieces of wood together.  

Step 7:

Attach your side pieces the exact same way that you attached your front piece  

Step 8:

Stand back and enjoy your AWESOME new DIY faux wood beam mantel!
