Poly Vinyl Acetate (PVA) Size 250 ml (8.5oz)

To start your painting journey on the right foot, it’s essential to coat your raw canvas with Gamblin PVA Size before applying either Oil Ground or oil paint. Conservation experts recommend using a neutral-pH PVA size, which is a fantastic alternative to traditional rabbit-skin glue. The beauty of PVA Size lies in its ability to create a stable sealing layer that protects your canvas without the risk of swelling or shrinking, as it doesn’t draw moisture from the air. Gamblin's PVA Size is animal-free, maintains a neutral pH, won’t yellow over time, and remains flexible without releasing harmful volatiles. Just a tip—use full-strength glue for attaching fabric or paper to your panels to ensure strong adhesion. Happy painting!

PVA Size on Canvas

Applying PVA Size to your canvas can be a fun and rewarding part of your creative process! You can coat your canvas with PVA Size either before or after stretching it, but generally, one coat on the front does the trick. If you notice any pinholes while holding the canvas up to the light, consider applying a coat to the back as well for extra protection. When stretching your canvas, make sure it’s done evenly and tightly!

Remember, PVA Size will initially tighten a damp canvas, but it may relax a little as it dries. For large canvases or lightweight linen, applying PVA Size first can help prevent any buckling or wrinkling, as heavier canvas tends to handle these issues better. Just a heads up: linen can shrink as it dries, so cutting your fabric slightly larger will be beneficial. And don’t forget to clean your brushes with soap and water after using PVA Size—happy creating!

PVA Size on Paper

When exploring the world of oil painting, it's exciting to discover that some papers come pre-sized for this medium, making things easier! Papers designed for heavy-water media like watercolour or mixed-media can also be transformed for oil painting with a little preparation. A fantastic option is Gamblin PVA Size, a reliable sealant. The great news is that once the PVA Size dries, the paper retains its original appearance, and you only need to seal the side where you'll apply your oil colours. For those prone to wrinkling, taping the paper to a sturdy panel before application is a smart move—be sure to wait until it’s fully dry to remove the tape. Typically, applying two coats of PVA Size is best, and allowing 24 hours for moisture to evaporate ensures an optimal surface for your artistry.

Painting on PVA Size alone

PVA Size is a fantastic option for artists looking to enhance their work without the need for a traditional primer! It allows the beautiful, natural colour and texture of your canvas or paper to shine through, making it perfect for those who want a more organic look in their oil paintings. While it may not be a conventional ground, PVA Size effectively protects your canvas from the acidity of oil paints. For the best results, applying two thin coats will help minimize absorbency while maintaining that lovely texture. The 8 fl oz size covering about 10 square feet. Your artistic journey just got even more promising with this versatile product!
