Fibre Glast - PVA Release Film

PVA, or polyvinyl alcohol, should be used with our #1016 Partall Wax for the easy release of parts from a mold. Wax should be applied to the mold, 3–4 layers thick, and buffed to a high gloss. Once the final layer of wax has dried, PVA should be applied with the following considerations:PVA can be brushed on, but for best results, apply with a spray gun, 12–18 inches away from substrate. Generally, apply in three layers: the first, a thin mist, allowing 10-15 minutes to dry completely.

Experienced fabricators will likely run across that hard-to-separate part, whether it's larger in nature or just stubborn—which presents a challenge for demolding. Standard wedges only reach a few inches into any mold, and using force can result in damage. Applied air pressure provides a solution.Our #958 Air Injected Wedge is designed to deliver air all the way to the sticking point to provide pressure where it is needed most.

This half lamb's wool-half synthetic pad is the best choice when time is a factor. Wool is simply a faster medium when compared to foam. Wool has become more popular as paints are required to contain more solids and fewer solvents. This mix of wool and synthetic is designed to work with our #1102 Step 1 and #1103 Step 2 Mold Polishes, and will withstand the 2500 rpm minimum buffing speed suggested for both.
