PVA (Polyvinyl Alcohol) should be used with regular Wax to aid in the release of parts from a mould, however many times we have used alone on mould surfaces. The PVA dries to form a smooth film.
After part release, the film can be removed easily with water. PVA can be sprayed, brushed or sponged on (depending on the size of the part), spraying we recommend at 50 - 80 psi.
Q & A
How do i apply PVA release agent?You can brush, spray or use a jenny foam brush to apply PVA release agent. If using a brush be careful not to apply too much, if spraying do so between 60 - 80 psi and apply thin coats to build up and if applying with a foam brush use nice even strokes and apply also in a thin uniform coat.
