Leaving dirt or other particles on the wood can keep it from properly absorbing the paint, primer, and sealant. Clean the wood before applying sealant by wiping it down with a damp cloth. You can use a tack cloth to pick up any remaining dirt. Tack cloths are gauze-like materials treated with a sticky substance and can be purchased at any home improvement store. Brush a thin coat of glossy acrylic medium sealant onto the wood using a dampened sponge or paintbrush. Allow the sealant to dry, and then apply another coat to the wood. Lightly sand the wood after the second coat of sealant has dried to remove any excess sealant and then wipe it down again with a wet cloth and tack cloth. Use a sponge for wood surfaces with grooves and curves and a paintbrush for flat surfaces. The sandpaper should be around a 220 grit. Using primer provides a surface to which paint can adhere by allowing the wooden surface to regain surface tooth (ridges and valleys). An acrylic gesso is probably your best option for using primers. You will only need to apply one coat of a high quality primer, lower quality ones might require a second coat. In order to maximize paint adhesion, you'll need to allow the primer time to dry. This could take several hours. Once the primer is dry to the touch, you can start applying your paint.
