Masonite is a brand name for hardboard, which is formed by pressing wood pulp into sheets using intense heat and pressure. It is a popular surface for painting, especially oil painting, due to its affordability and availability. However, it requires proper preparation to ensure the paint adheres well and does not chip or peel over time. This includes cutting the panel to size, sealing the edges, sanding the surface, applying a primer or gesso, and possibly adding a canvas on top for better paint adhesion. While Masonite can be a durable and cost-effective alternative to canvas, it may not be suitable for large-scale paintings due to weight concerns and the potential for warping.

What You'll Learn
Masonite is cheaper than canvas
Masonite is a popular surface for painting, especially for those who want to save some money. It is a cheaper alternative to canvas, and many artists prefer it for this reason. It is also thinner than canvas, making it easier to cut to size and manage, as well as being more archival than cotton or linen canvas. However, Masonite does have a tendency to bow, bend, and warp, so it often requires framing or support to remain flat.
When painting on Masonite, it is important to seal all edges to prevent warping. A polyurethane sealer can be used, followed by a layer of gesso applied in a haphazard fashion with varied brushstrokes. Some artists also recommend sealing with an acrylic gloss medium before the gesso to prevent yellowing over time. While Masonite is a great option for small paintings, larger pieces may be too heavy to ship and hang. Additionally, some artists find that their paint chips off Masonite, and it can be challenging to get paint to adhere to the surface.
One way to improve paint adhesion on Masonite is to add "tooth" to the primed surface by sanding it with fine sandpaper before painting. Another solution is to use a small paint roller, such as the RollerFoam brand, which creates a canvas-like texture on the smooth surface of the Masonite. This allows the paint to lay down more effectively and prevents the brush from picking up the paint.
Overall, Masonite is a cost-effective alternative to canvas for artists, especially for small paintings. With proper preparation and sealing, it can be a durable and archival surface for artwork. However, it may not be suitable for large-scale pieces due to weight and shipping concerns.

Seal all edges to prevent warping
Masonite is a type of hardboard, made from wood fibres and resin. It is a popular surface for painting, especially oil painting, due to its smoothness. However, it can be tricky to work with because of its tendency to warp. Sealing all the edges of a masonite board is crucial to preventing warping.
Before applying any primer or paint, cut the masonite to size. Then, seal all six sides of the board to prevent moisture from getting in or out. You can use a solvent-based acrylic sealer like Paraloid B72, which is supplied in clear pellets with no air restrictions. Dissolve it in 100% ethanol and apply several coats to the front, back, and all four edges of the board. Alternatively, you can use a polyurethane sealer, which is also effective in preventing warping.
If you are using gesso, a common primer for masonite, you can apply it to the smooth painting side in a haphazard fashion with varied brushstrokes. Let it dry, and then repeat two to three times for each side and the edges. You can also use a layer of acrylic gloss medium before the gesso to seal in tannins and prevent yellowing over time.
If you are experiencing paint chipping, you can add tooth to the primed surface by sanding it with fine sandpaper before painting. Additionally, if your board is warping convexly, you can try dampening the concave side and applying heat with an electric iron to fix it.
Sealing all edges of a masonite board is crucial to preventing warping. By using the appropriate sealants and techniques, you can create long-lasting paintings on this unique surface.

Sand the Masonite to improve adhesion
Masonite is a challenging surface to paint on due to its smoothness. Artists have reported issues with their brushes picking up the paint instead of laying it down, resulting in visible brushstrokes and layers of paint lifting up. To address this issue, it is recommended to add "tooth" or texture to the surface by sanding it lightly with fine sandpaper before painting. This technique scuffs the surface, creating a better adhesion for the paint.
When preparing Masonite for oil painting, it is crucial to start with a properly cut panel. Cut the Masonite to the desired size, then seal all the edges to prevent any issues with warping. A polyurethane sealer can be used for this purpose. Once the sealer is dry, you can move on to the next step of preparing the surface for paint.
To improve adhesion and create a textured surface for paint to adhere to, sand the Masonite lightly with a sanding sponge or fine sandpaper. The key is to scuff the surface without gouging any sections. You can sand the panel in different positions and vary your strokes to ensure that every part of the surface is covered. After sanding, use a soft, clean cloth to wipe away any residue.
After sanding, you can apply a primer or gesso to the Masonite panel. Gesso is a primer commonly used to prepare painting surfaces and is available at art supply stores. Apply the gesso with a foam brush, covering the entire surface, and let it dry for about 30 minutes. It is recommended to apply at least three layers of gesso, changing the direction of your brush strokes with each layer. For an eggshell-smooth finish, you can lightly sand between each layer of gesso. If you prefer more texture, you can skip sanding between layers and simply sand after the final layer.
By following these steps of cutting, sealing, sanding, and priming the Masonite panel, you will create a textured surface that improves paint adhesion and provides a suitable foundation for your oil paintings.

Use a roller for even coverage
Painting on masonite can be tricky as it can get very slick when applying paint if not prepped well. It is important to seal all edges of the masonite panel. You can use a polyurethane sealer for this. After sealing, you can apply a coat of primer. Some people use white acrylic primer for this. However, if you plan to use oil paint, you should seal the masonite with a layer of acrylic gloss medium before applying gesso to seal in tannins and prevent possible yellowing over time.
Once you have applied the primer, you can start painting. However, when using brushes, you might find that the paint is being picked up by the brush instead of being laid down. This is where a roller comes in. Using a roller can help you achieve even coverage. First, moisten the roller with water for latex paint or the appropriate thinner for other types of paint. Roll out the excess moisture on a piece of scrap lumber, kraft paper, or a paper grocery bag. Don't use newspaper because the roller may pick up the ink.
Next, fill the well of the roller pan about half full and set the roller into the middle of the well. Lift the roller and roll it down the slope of the pan, stopping just short of the well. Do this two or three times to allow the paint to work into the roller. Then, dip the roller into the well once more and roll it on the slope until the pile is well saturated. You'll know immediately when you've overloaded the roller as it will drip and have a tendency to slide and smear instead of roll across the surface.
The most effective method of painting with a roller is to paint 2- or 3-square-foot areas at a time. Roll the paint on in a zigzag pattern without lifting the roller, as if you're painting a large M, W, or backward N. Then, still without lifting the roller, fill in the blanks of the letters with more horizontal or vertical zigzag strokes. Finish the area with light strokes that start in the unpainted area and roll into the paint. At the end of the stroke, raise the roller slowly so it does not leave a mark. Go to the next unpainted area and repeat the zigzag technique, ending it just below or next to the first painted patch. Finally, smooth the new application and blend it into the previously finished area.
Using a roller can help you achieve even coverage when painting on masonite. However, it is important to properly prepare the masonite surface and not overload the roller with paint to avoid dripping and smearing.

Seal with a polyurethane sealer
Masonite is a generic name for single or double-tempered hardboard. The “tempered” side acts as a sealer. To improve adhesion, it is recommended to sand the sheets before applying a primer. You can use a product like TuffPrime or Aqua Lock, then seal it with a polyurethane sealer.
To seal Masonite with a polyurethane sealer, follow these steps:
- Cut the Masonite panel to size.
- Seal all edges and one side of the Masonite with the polyurethane sealer. Allow it to dry, then coat the other side.
- Apply gesso to the smooth (painting) side. You can apply it in a haphazard fashion with varied brushstrokes, especially if you're creating landscapes.
- Let the gesso dry, then repeat the process for each side and the edges, applying two to three coats in total.
You can also use a clear coat or a specific waterproofing sealer to seal Masonite. If you're sealing Masonite that has already been installed, it's important to waterproof the surface to avoid structural failure due to moisture absorption. Prepare the surface by sanding it with 100-grit sandpaper and wiping away the dust with a clean rag. Then, apply the waterproofing sealer using a hand-pressurized spray bottle. Allow the sealer to cure for five to six hours before applying additional coats or paint.
