Finishing Instructions
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 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.

I really wish you listed the 28 1/2 board in your cut list.... I now have an extra 25 1/2 and am short a 28 1/2 cut....

Would this be any more sturdy with pocket holes? Or same regardless. I’m new to this and haven’t used my kreg jig yet so not sure what the difference is. Also would it be good to add a support in the middle or no need? Thanks for all the amazing plans! I made the mud kitchen (second project ever) over the weekend and you make it so easy to follow! I’m addicted now!

Cant find self-tapping exterior deck screws but says wood to metal, not wood to wood.

Anyone have a link to these type of screws needed?
