Cut Posts

Referring to dimensions on notepad, measure post, then mark with pencil. Cut posts to size using chop saw.

Saw the Posts

Attach Plywood to Posts

With help from a friend, firmly hold plywood still and in place perpendicular to post. Using drill, attach posts to plywood with wood screws directly through plywood and into top of post.

Drill Wood into the Post

Add Trim

Using nail gun, attach mitered pieces of 1x3 MDF to front of plywood.

Create the Trim

Prep for Paint

Fill gaps, nail holes and screw holes with wood filler using putty knife. Caulk spaces between trim and plywood with caulk gun. Once wood filler and caulk have fully dried, sand all surfaces using orbital sander and medium-grit sanding pads. Wipe dust from surfaces with damp cloth.

Prime, Paint and Seal

Load primer into paint sprayer, then spray in a steady, controlled manner keeping sprayer eight inches from surface of desk. Once primer is dry to the touch, clean out sprayer, load finish color, then spray two even coats in a steady, controlled manner, keeping sprayer eight inches from surface of desk. Once finish coat is dry, repeat painting steps using floor sealer. Tip: Allow at least 24 hours' drying time before placing objects on sealed surface.

Prime and Paint the Desk

Create and Install Cleat

Create cleat by cutting one piece of 1x3 MDF approximately two inches shorter than width of plywood top. Place cleat below marked line on wall, attaching it to the wall with drill and wood screws.

Attach a Wood Cleat

Attach Desk to Cleat

Place desk directly on top of cleat. Fasten plywood top to cleat with wood screws driven through cleat into the underside of plywood.
