PVA Release Film
Easy Spray-On – Easy Release for Molds
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. Then apply two heavier flow coats, allowing each to dry completely (30-45 minutes each).
- PVA should form a smooth, glossy surface that will not shrink or pull away from corners or curved surfaces.
- It may be applied over polyester repairs, or gel coat, as a surface layer for airless tack-free cure.
As a dry film, PVA is resistant to the solvents in a resin system, but is water soluble. PLEASE NOTE: It should not be used with resin or substrate that contains—or produces—water during cure.
One gallon covers approximately 400 square feet.

Worked great!

This was my first time every copying a piece (hood scoop). I applied this with a brush, allowed to dry and put resin and cheese cloth directly over it and popped it free with compressed air. I wish I had starting doing this years ago!
Works Great!

I've never made a mold before, and there are a lot of opinions about the best way. Some say wax, other say wax and releasing agent. Spend the $$$ and buy a releasing agent. This purchase saved my project from certain destruction. Quick service from Fibre Glast was amazing!
PVA 13

I recently ordered the PVA 13 product to build a new fiberglass mold. It is recommended that the product be sprayed but can be sponged on. I used an ultra smooth paint roller and I can't begin to tell you how nice it surfaced. Once more I was really concerned about how the mold would pull from the master due to all the curves and angles. It couldn't have pulled cleaner. Very happy with the product.

I have used other release films in the past and all were similar to this product. When spraying on the mold the others did not give a nice smooth texture there was always some orange peel to it. This PVA was much better. I sprayed it on the mold according to the directions and it flowed out to a perfectly smooth film. When it came time to release the part from the mold it was almost too easy. The part just pulled right out of the mold with hardly any effort. This is a great product and I will be using it on the rest of the molds and parts for my rc airplane. I am confident that all future parts will turn out perfect with the use of this product.
PVA Release Film PVA is available in a variety of sizes that include: One quart (#13-A) One gallone (#13-B) One case of 4 gallons (#13-C)
