Step 9: Shelf Installation
I laid out a rough grid indicating where I thought I'd want supports and used blue painter's tape to get an idea of where they'd be. After making a few adjustments in spacing (moving the tape around), I had a good idea where I wanted the supports, and put pieces of blue tape in the approximate positions. Using the tape allows you to do all your marking of the exact position on the tape, so you're not marking up your wall with pencil lines you'll have to clean off later. I also used a piece of thread stretched between push pins as a layout aid to make sure that all the supports at a particular height were mounted at the same level.
Once positions are marked, I installed screw-in drywall anchors and their anchor screws making sure that the drywall anchors were as flush to the wall as possible. Next, hang the shelf supports (with the glass clips loose) on the anchor screws. Adjust the screws in and out until the support has a snug fit against the wall - but not a tight fit. You want the supports to bottom out on the anchor screw for a nice solid mount. Once the supports are in place, slide the glass shelf into the glass clips (which should be a little loose) and adjust the shelf side to side to the desired position. Next take blue painter's tape and tape the clips to the glass shelf - locking them in position. Lift the shelf with the supports off the wall and flip it outer-edge down. Make sure the clips are fully seated against the back of the shelf and tighten the screw. The clips will snug up against the glass and hold it firmly. Peel the tape off, wipe down the shelf, and hang it back on the wall. You may need a few gentle taps of a rubber mallet to make sure the supports are fully seated on the anchor screws, but most will slide down for a snug fit.
That should be about it! You now have some new super-cool glass shelves :)
