Gamblin PVA (neutral pH Polyvinyl Acetate) SIZE For linen and canvas seals the porous surface of fabric support. The advantage of PVA glue is its stability. After PVA is dry, the glue does not absorb atmospheric moisture. So it does not expand and contract under dried paint film like rabbit skin glue does. The more stable the glue size layer, the less likely the painting will crack over time.
