How to Paint a Long Board Deck
Hand Sander with 80-120 git sandpaper
Caulk, modeling paste, or gel medium (optional)
360-600 smooth grit sand paper (optional)
White drawing chalk
Steps for painting on a wood surface.
1. Sand off the previous layer of paint, and wipe the board clean. You will need a medium grit sandpaper for this (80-120)
2. Decide if you want to fill the screw holes or just leave them (I left mine). If so, you can use caulk, modeling paste, or gel medium.
3. Gesso the deck with a smooth, synthetic brush one or two inches wide. I did three layers. Each layer must fully dry (20 minutes or more). Each layer should be painted on in the opposite direction of the previous layer. This is so that the layers of gesso fill in the lines the paint brush left behind.
Example: gesso left to right, then up and down, then left to right again.
If you want it really smooth, you can gently sand each layer of gesso (with a fine grit sand paper 360-600 grit) before adding the next layer. Be sure to wipe the board clean after sanding. You can paint on as many layers of gesso as you need to achieve the desired smoothness.
4. Paint an Undercoat. I start every painting by covering the entire surface with a bright, warm color: orange, yellow, pink. I choose a warm color because they are easier to cover up that a cool color.
Example: blue covers yellow, but yellow will not cover blue.
Now, I am able to sketch my design with white drawing chalk.
5. Sketch out a design with white chalk.
I do not use pencils, pens, or sharpies because many acrylic paints are fairly translucent, and my underdrawing will show through. Also, black chalk can contaminate the color, and some inks bleed through paint (sharpies being one of them).
6. Once your design is sketched, start painting.
7. Time to Varnish. Let your painting dry for three days before you varnish. Although acrylic paint drys fast to the touch, it is often not fully dry. You can use a spray on varnish or a brush on. Varnish comes in gloss, matte, semi-gloss, satin... there are plenty of choice, pick your favorite.
8. Your done! Display your masterpiece by attaching sawtooth hangers on the back, or using J hooks on your wall.
