Description:
 
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. 
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.
Suitable for preparing porous surfaces sucha s canvas for oil painting. Sizing is not required for wood panels, use only a ground.
