Step 2:

It starts with a big X. Be sure you are working on a very flat, level surface. Use pocket hole screws and glue to the joint in the center as shown above. You could also use metal straps or plates but you can only place the metal plates on the bottom side.

Preparation Instructions: Fill all holes with wood filler and let dry. Apply additional coats of wood filler as needed. When wood filler is completely dry, sand the project in the direction of the wood grain with 120 grit sandpaper. Vacuum sanded project to remove sanding residue. Remove all sanding residue on work surfaces as well. Wipe project clean with a damp cloth.

It is always recommended to apply a test coat on a hidden area or scrap piece to ensure color evenness and adhesion. Use primer or wood conditioner as needed.
