How to Build Floating Shelves

Liam’s nursery was pretty bare, so we wanted to create some built in book shelves for his giant library we got from friends and family at our baby shower. (A great idea by the way: have your friends and family sign the inside cover and bring a book, rather than a card to your shower.)

Here’s how I built his floating shelves to appear to have no support underneath, and still hold the weight of all his books.

Step 1 – Cutting and Drilling the Shelf Supports

After measuring out the length of the shelves you want (I did mine in an L shape for the corner of the room) measure out the 2×12’s to length and cut to size.

Once cut to size, you’ll want to drill a 1/2″ round hole at least 6″ deep on each end of the shelf board, and if the shelf is longer than 2 feet, every 2 feet or so. This hole will eventually have a 1/2″ dowel inserted that will support the shelf to the support you attach to the wall. It’s critical that these holes are square to the flat surface of the board… if they are not, the dowels could end up opposite angles of each other, and when you try to insert the shelf onto the support, it will bind up… You may not understand what I’m talking about here yet, but just know you need to make sure that hole is completely squared to the board and perfectly straight!

After drilling your dowel holes, cut a strip off the side of the 2×12′ that you drilled into at about 2″. This will be your wall support and is the magic behind floating shelves. Your end result should be about a 2″ square piece that is as long as your shelf with a 1/2″ hole all the way through it at it’s ends (and maybe in the middle depending upon length), and the remaining 2×12 (now 2×10) which should still have 1/2″ holes about 4″ into it. Cutting after you drilled the dowel holes ensures they will line up perfectly later when you put the two cut pieces back together. Label the supports with the shelf you cut them from, so you know which ones go together.

Next, on the inside (where the saw blade was cutting) of the small 2×2 support piece, you’ll want to drill some recessed holes (only 1/4″ deep) where you will later screw these to the wall, and that will recess your screw head so it doesn’t get in the way when you attach the shelf.

Finally, cut your 1/2″ dowel into 5 7/8″ pieces so they will fit into your 6″ holes and not stick out. Sand everything including the dowels EXCEPT the cut side of the shelves and cut side of the wall supports where they separated originally. If you sand these, when you put them back together, they will not line up flat, you will have a small dip in your shelf, and the connection points will be obvious defeating the magic of floating shelves.

Insert the dowels into the small support 2×2″ so that they are sticking out of the end that has your recessed 1/4″ screw holes. The picture below of what your finished product should look like for the shelve wall supports.

How the Supports will Go Together with the Shelves… Don’t push them together yet, we actually have to attach the wall support to the wall first!

Step 2 – Attach the Wall Supports to the Wall, and Slide On Shelves

The short of this step is to attach the wall supports to the wall by inserting screws into the recessed screw hole areas you created, so that the dowels are sticking out from the wall.

To do so with anchors into drywall, you’ll most likely want to drill a pilot hole all the way through your recessed screw area on one side of the wall support first. Then remove the support, and place your anchor into the drywall or plastered wall. Next replace the support once again and insert your screw into the anchor holding one side of the support onto the wall – just not too tight, so that it can swing down and out of the way as needed.

Get your level out and make sure the shelf is completely level on the opposite end that hasn’t been screwed into the wall yet. Once level, drill your pilot hole to the wall to make your mark for your next anchor. Let the wall support hang down from the one attached end so it’s out of your way to insert your anchor. Once done, swing back up the wall support and insert the screw. Your shelf support should now be attached to your wall! (Note if you have more than one area to screw the support into the wall, which I suggest at least in between each dowel, you may need to drill more pilot holes and add more anchors before securing each end.)

Finally, you can slide your shelf onto the wall support by inserting the dowels sticking out from the wall into the shelf. Below is an image of the shelves attached to the wall supports and on the wall!

Caulking to Hide Joints
If you want to fill the connection points to make them appear smoother, caulking is great if you intend to paint rather than stain your shelves.

Step 3 – Add Trim for a Professional Finished Look

Trim is so simple to do, and adds so much to the final product. You can buy it super cheap as well. I got some small trim to add to the top edges of the shelves. Simply measure the length of each, and cut the ends of the trim on a proper 45 so that it matches up with the next piece for that corner.

Use finishing nails to attach the trim to the edge of the shelves.

Adding Decorative Trim to Shelves
Measure and mark your 45 degree angles for the trim, and then cut with a circular or table saw.

Using a Nail Punch
Pro Tip – use a “Nail Punch” so that you can recess your finishing nails just a tad below the trim surface, without having the hammer hit or dent the trim!

Step 4 – Sand More, Then Paint Your Shelves!

Do a bit of final sanding now that they are on the wall and you can see what needs to be sanded. Do a little final fill with caulking as well if you plan on painting to hide other imperfections, or fill the finishing nail holes for example on the trim.

Paint Paint Paint – multiple coats looks best. Use a primer to start with on the raw wood.

Preparing for “Liam” – Nursery Remodel Begins

Day 353
Total Spent So Far: $85,814.47
30 Yard Dumpsters Filled: 3.5

It’s been a while since I last posted. But a lot has happened. The next 4-5 blog posts will be “catch-up” for everything I haven’t written about over the last three months. We’ve been incredibly busy, not only with the remodel, but also with our precious new born son (don’t skip ahead readers!) To top it off, our annual music festival, Backwoods, is quickly coming upon us. All of this combined with our software company PromoJuice growing as fast as it is has stripped me of any free time to write really. So, catch up it is. I owe it to myself, and to our readers following along.

As with the rest of the house, Liam’s future room hadn’t been updated since the 70’s or 80’s. The room needed to be done from floor to ceiling, electrical and all. As with every room, we started with the demolition, removing the fan, the old closet doors (that were being used as doors to the room), pulled the mirror off the wall, the bathroom light fixture, and prepped the walls for painting.

We decided to move forward with remodeling the hallway at the same time as Liam’s room since it connected our bedroom, which we had already painted, completed electrical, and ceiling work in. So the very first step was painting both the nursery and the hallway.

To speed up the process I used a paint sprayer, which is messy as hell, but gets the job done incredibly fast. You really have to make sure EVERYTHING is out of the room which you don’t want paint on, or at minimum covered. Don’t be surprised if it gets under the cover still. We plastic sheeted off every opening to the other rooms we didn’t want paint on.

I decided I would build some floating shelves in Liam’s room, after Shaleece presented me with the idea, and as with everything told me, “Come on, you can do it. It will be easy for you!” They actually turned out really awesome, and I documented the entire process; so, I’m going to put up a post dedicated to “How to Build Floating Shelves” in case any of you want to try your hand at some carpentry for the next article as a side bar to our remodel progress.

After the shelves were done, and room painted, besides some minor electrical and fixtures work, the flooring was the next major job to tackle. I learned a thing or two in my day about laying tile (this isn’t the first house I’ve laid tile in) and the best advice I can give is to spend the extra money on a Floor Leveling System. It keeps any “lippage” from occurring by simultaneously lifting the tile from the bottom, and squeezing down on it from the top, at the corners where multiple tiles meet. Basically, if you’ve ever seen a room where the tile edges are at different heights (causing edges) it’s because they didn’t use one of these systems and probably used the good ol’ regular spacers. It’s almost critical in a house like ours where you have multiple types of flooring meeting up in different areas at slightly different heights.

Sebastian learned a thing or two about tiling and helped as well. He got an opportunity to use the tile saw, lay some mortar, and throw a few tiles into place. He did great for his first go-around.

We more or less finished up in Liam’s room with the exception of the windows and the barn doors which have been on order. The photo doesn’t show the grout, but that’s been complete as well. I’ll be sure to post some final photos of the room once the barn doors are up and the new windows are installed… “Soon Come” as they say on the island. Liam will be here soon, and we can’t wait…. well actually I’m playing catchup and most of you guys know he’s already here… but that’s what I was thinking at the time I actually took this photo… 🙂
