Gamblin PVA Size for Stable, Archival Fabric Sealing

Gamblin PVA Size is a modern, conservation-grade sizing agent designed to protect fabric supports like canvas and linen before oil painting. Made from polyvinyl acetate (PVA), it acts as a reliable barrier that seals the fabric's porous surface—preventing oil paint from sinking into and degrading the fibers over time. Unlike traditional rabbit skin glue, PVA Size is neutral in pH, non-yellowing, and remains flexible without absorbing atmospheric moisture, swelling, or shrinking.

Ideal for use before applying an oil ground such as Gamblin Ground, PVA Size can be applied to unprimed fabric either before or after stretching. Its stability and resistance to moisture-related changes make it a top choice among conservators and artists alike who are seeking a dependable, long-lasting alternative to traditional sizing materials.
