Installing A Floating Fireplace Mantel

Floating fireplace mantels are great to use when you wish to place something large and important over your fireplace or if you have a small fireplace with no room for a large fireplace mantel and surround. Other people use these just because they are unique and simple at times.

Installing a floating fireplace mantel is a very easy process that requires little to no time to do. But before you can install one you first have to choose one. Visit your local home department store and choose the style and size that you love and the one that will work best in your home. Make sure to measure the space you want it to take up so you do not get something that is too small or large.

Directions

  • The first thing that you will need to do is figure out the height that you want the mantel to be. Usually people will place it 60” above the floor. Make sure to mark the grout line close to the height that you chose. Set the marks on the grout line every 16” in order to keep the marks level and centered. You need to mark the length of the mantel.
  • Drill the holes for every mark and use a drill with a ¾” masonry bit. The drill bit needs to be marked with tape at the 3” mark. This will determine how deep it will go.
  • Next you need to set up the lead sleeves into the holes. These are ridged and made to grab hold of the masonry surfaces after the lag screws have been installed.
  • Set up a 10” lag bolt into each of the sleeves and secure them tightly. When the bolts are secured to the lead sleeves you need to use an angle grinder to cut off the heads from the lag bolts.
  • On the back of the floating mantel you need to mark the rear where the lag bolts will hit. You need to measure and mark the mantel holes so that they align just right with the lag bolts. Drill ½” holes all across the back of the mantel for the lag bolts.
  • Set up high temperature silicone to the end of each lag bolts. Then lift the mantel into position and push it firmly on the lag bolts.
