Gamblin Poly Vinyl Acetate (PVA) Size

Diluted with distilled water, PVA size is a contemporary size for fabric support. PVA seals the fabric but does not re-absorb atmospheric moisture, preventing the size layer from swelling and shrinking. It has a neutral pH and does not yellow, plus it retains its flexibility and does not emit harmful volatiles. Available in an 8 oz. bottle. PVA size protects the fabric from the ground. PVA does not tighten the fabric like rabbit skin glue, so stretch fabric tightly.
