Gamblin PVA Sizing

Gamblin's contemporary mediums are true to historic working properties, yet safer and more permanent. These painting mediums extend and modify the working properties of oil colors, offering fluid consistency for expressive mark making to a stiff paste for creating thick, crisp marks. Gamblin's mediums broaden the visual qualities of oil color while increasing the transparency of paint layers and creating a range of surface qualities from high gloss to matte.

PVA Sizing (Poly Vinyl Acetate) - Diluted with distilled water, PVA size is a contemporary size for fabric support. Conservation scientists recommend painters use neutral pH PVA size on linen and canvas instead of rabbit skin glue. PVA provides a good size layer that seals the fabric but does not re-absorb atmospheric moisture, swell and shrink like rabbit skin glue does. There are hundreds of different formulae of PVA. We acknowledge and appreciate the research of the Canadian Conservation Institute that helps painters and conservators identify the best PVA to use. Gamblin PVA Size is made from PVA that has a neutral pH and does not yellow. It also retains its flexibility and does not emit harmful volatiles.
