PVA (Polyvinyl Alcohol) should be used with #1016 Wax to aid in the release of parts from a mold. It should be applied in three thin mist coats over nonporous, waxed mold surfaces. After the final wax coat has dried, begin by spraying a light tack coat of PVA. Typically, within 5 minutes the final heavier coats can be added. The PVA dries to form a smooth, glassy film. After part release, the residual film can be removed with water. We recommend using our 123-A or 126-A Touch Up Spray Guns for larger molds, but for smaller molds, use our 2251 Preval Sprayer . PVA can also be sprayed over any polyester repair to provide an airless tack-free cure.  

Paste Wax is a non-silicone green wax specially formulated to produce a tough, durable, high gloss surface. Excellent release characteristics are achieved when used with # 13 PVA. We recommend that new molds are coated with four layers before use. Apply two coats of wax, buff off the excess, and allow to stand for an hour before applying the last two coats. The wait is to give solvents extra time to evaporate so a tougher wax barrier develops.  

Fibre Glast's first one step release agent is compatible with all our resins, saves valuable time, and uses little material. Mold preparation and cleaning times are so quick you'll feel guilty! We have tested this product during both part and mold fabrication with excellent results. Water-based FibRelease® contains no harmful solvents, chemicals, or silicones so it is worker and environmentally safe. It has been developed as an easily applied, non-VOC, non-silicone, non-transferable material with effortless release characteristics. It is compatible with the paintshop environment, and will not easily pre-release. Application is easy! We recommend starting with a properly polished mold surface,and rebuffing as necessary to maintain the Class "A" finish. Simply mist or wipe FibRelease® onto the mold surface and allow it to dry to its film state. 5 minutes is usually sufficient. One application will provide multiple releases, but the process is so quick we recommend using it every time for added insurance. The maximum service temperature is 550° F.  

Meguiar's Mirror Glaze products comprise a complete production mold system based upon proper mold preparation and a paste wax. The advantages of this system are many; it yields parts with a very high gloss, involves no time consuming sprays and , with proper care, provides trouble-free releases. This system is compatible with PVA for added release insurance.  

Plastic release wedges are used to aid in removing medium to large parts from a mold. The wedges are inserted around the perimeter of the mold, between the mold and the part, and then gently driven in until the piece pops out. The theory behind using a wedge is that concentrated pressure is applied to that portion of the part not yet released. To make this scheme work it is necessary to use a sufficient number of wedges and to progress around the mold tapping each wedge in turn. One wedge will not help. The soft polyethylene construction will not scratch the mold or the part. 

Designed for demolding large or hard-to-separate parts. Standard wedges can only reach a few inches into the mold, but air pressure will travel all the way to the sticking point to provide pressure where it is needed most. This heavy duty poly-pro wedge is designed for extra long life.  

As shown in "A Step by Step Guide to Molding Fiberglass", this unique clipping system quickly joins multiple piece molds during final assembly. Using 1/8" holes, the clips hold the mold tightly to prevent slipping and misalignment. Use the Fastening Clip Plier to quickly attach and remove the special clamps.   

KLEEN KLAY® is a non-drying clay having many applications in most phases of fiberglass molding including temporary fillets, construction of mold parting lines and quick repairs to molds. The oil base of this clay allows PVA separator to be applied to it and also provides a good measure of adhesion to waxed surfaces. KLEEN KLAY is a registered trademark of Art Chemical Products.
