How to prepare a wooden artist panel for acrylic painting
As an artist, the support you choose for your work can have a significant impact on the final result. Wooden artist panels are a popular choice for many reasons, but preparing them properly is crucial to ensuring the longevity and quality of your work.
What kind of wooden panel should you use?
When choosing a wooden artist panel, it is important to select one made from hardwood, rather than a composite material like MDF (medium density fibreboard). Hardwood panels are more stable and less likely to warp over time, which is essential for maintaining the integrity of your painting.
In terms of specific hardwood varieties, there are a few key factors to consider. The type of wood you choose will depend on the medium you are using and the desired finish of your piece. For example, if you are working with acrylic paints, a smooth wood like birch or maple will provide a good surface for your paint to adhere to.
Personally, when I make my own wooden artist panels I like to buy marine grade hardwood ply board from my local Bunnings. However, one important tip is to closely inspect the surface of the panel that you purchase. In large hardware chains, the high volume of wood turnover can mean that there is some variety in finishes. The wood may also have been knocked around by handling of other customers. So choose wisely!
Where I get my wooden artist panels
There are a few options for where to source your wooden artist panels. You can make them yourself if you have the necessary tools and skills, or you can buy them from a local framer or art supply store. If you choose to make your own panels, be sure to select high-quality wood and take the time to prepare it properly.
I like to make my own because that allows me to create panels in any size I need. However I think it would likely be a comparable cost to get my framer to make my panels if I am looking for a more standard size.
Why prepare your wooden artist panel?
Preparing your wooden artist panel is an important step in the process of creating a work of art. There are two main reasons for this: Support Induced Discolouration (SID) and warping due to shifts in humidity.
Support Induced Discolouration (SID) is a phenomenon that occurs uniquely with acrylic paints. The natural impurities in wood can cause an amber yellow discolouring to any light-coloured or clear acrylic layer that is applied to the wood. This can be avoided by properly sealing your wooden artist panel before applying any paint.
Sealing (sometimes called sizing) your wooden panel can also help reduce the chances of warping due to shifts in humidity. Warping can distort the surface of your panel and make it difficult to paint on, so taking the time to seal your panel can help ensure that it remains stable and flat.
Steps involved in preparing your wooden artist panel
Prepping your wooden artist panel is an essential step to ensuring that your artwork has a stable and durable surface to adhere to. Follow these steps to prepare your wooden artist panel for painting:
Seal your wooden panel. I use two coats of GAC 100 by Golden. Sand between coats to smooth out any rough spots. The first coat of GAC 100 will be absorbed quickly by the wood, so be sure to apply a generous amount. It will also bring out the tooth of the wood which is why the sanding is important. The second coat will require less GAC 100, as it will sit on top of the first coat.
Prime your wooden panel with at least two coats of a high-quality gesso. I use Golden for my gesso, but there are many other options available on the market. You can sand between layers of gesso to create an ultra-smooth surface if desired. Make sure you allow each coat to dry completely before applying the next.
Gesso is absorbent in nature, so be sure to apply your gesso evenly and carefully. This will help to ensure that your artwork has a stable base to adhere to, and will prevent any warping or bubbling of your paint later on.
By following these simple steps, you can prepare your wooden artist panel for painting and create a durable surface for your artwork. Happy painting!
