Apply an acrylic primer to the pressure-treated porch woodwork as soon as possible after the wood has been installed. Use a regular paintbrush to apply a 100 percent acrylic primer designed for pressure-treated wood. Wear protective gloves. Wait for the first coat of primer to dry before applying the second layer.
Wait two to three months before painting the wood. Attempting to paint the wood before this time has elapsed will result in a poor finish because the paint will not adhere.
Paint the pressure-treated wood with a latex or oil-based paint suitable for exterior woodwork and pressure-treated wood. Use a 3-inch paintbrush and paint in the direction of the wood grain. Apply two to three layers of paint, allowing drying time between each coat.
Things You Will Need
- Acrylic primer
- Paint or wood stain
- Consider painting the porch with a white wood stain, because stains often produce a better finish than paint.
