While you can paint canvas with wall paint, it's generally not recommended for artwork intended to last.
Here's why:
-
Longevity Concerns: Wall paint (typically latex or acrylic latex) is formulated for walls, not archival art. While it might look good initially, it's not designed for the same long-term durability as artist-grade acrylic or oil paints. As the reference mentions, wall paint is designed to last a few years, not centuries. Artist-grade paints are specifically formulated with lightfast pigments and binders to ensure longevity.
-
Flexibility Issues: Canvases flex, and wall paint, being less flexible than artist-grade paints, is more prone to cracking and peeling over time.
-
Pigment Quality: The pigment load and quality in wall paint are lower than in artist-grade paints. This can lead to less vibrant colors and a higher likelihood of fading.
-
Adhesion Problems: Wall paint is formulated to adhere to primed walls. While it will likely adhere to a primed canvas, the bond may not be as strong as with artist-grade paints, increasing the risk of peeling, especially with movement or changes in humidity.
If you still want to use wall paint on canvas, consider these points:
-
Proper Priming: Thoroughly prime the canvas with a good quality acrylic gesso designed for artists. This will create a better surface for the wall paint to adhere to.
-
Use as a Base Layer: You could potentially use wall paint as a base layer or for texture, and then paint over it with artist-grade acrylics or oils for the final image.
-
Consider Cost: While wall paint may seem cheaper, you might end up spending more in the long run if your artwork deteriorates and needs to be redone.
Alternatives:
- Use artist-grade acrylic paints. They are water-based, versatile, and relatively inexpensive.
- Consider student-grade acrylic paints as a more affordable alternative to professional-grade. They offer a better balance of cost and quality than wall paint for canvas art.
In summary, while technically possible, using wall paint on canvas is not ideal for creating lasting artwork. Artist-grade paints are specifically formulated for longevity, flexibility, and color vibrancy, making them a much better choice for canvas painting.
