How to paint an outdoor mural on a wooden fence
While a beautiful mural painted onto the side of a wooden fence can add significantly to your landscape, the idea of creating a painting of this impressive size can be intimidating. Taking a small sketch and making it become a very large painting on an exterior surface requires a unique approach to painting.
To complete such a project, you must first determine how to prepare the surface, what kind of paints should be used and how to copy a small sketch onto the fence that is to be painted.
Pressure-wash your fence and fill any blemishes on its surface with wood filler.
Mark a sheet of drawing paper with a grid of 1-inch squares. One square inch on your paper will equal one square foot on your fence.
Draw a sketch of your design on the paper grid and colour it in lightly with coloured pencils.
Apply two coats of acrylic primer to your fence with a roller.
Apply one coat of acrylic-based exterior white paint to your primed fence with a roller.
Use a level and dark chalk to draw a grid of 1-foot squares on your fence.
Using your small drawing as a reference, copy the drawing, square by square, onto your fence in dark chalk. If you transfer your drawing one individual square at a time instead of viewing the drawing as a whole, it will be easier to copy onto the large grid.
Paint in the chalk outline with the outdoor-use acrylic paints. Match the colours used, square by square, to the colours used in your small drawing.
Paint two coats of acrylic varnish over the fence with a roller to protect your painting from the elements.
- If your fence was originally painted with a high-gloss, oil-based paint, you will need to sand the gloss off of the surface before you can apply your acrylic primer or paints.
- Cadmium and cobalt colours are prone to premature fading.
- Varnish should not be applied during windy or damp weather.
