You Will Need: EZ-Brush Vac Bag Silicone,

Step 1: Creating an EZ-Brush Vacuum Bag

A tool used to produce the hull of the Vapor Optimist racing boat is prepared for production and a channel is routered into the tool that will aid in providing an airtight seal between the tool and the vacuum bag. Next, mix and vacuum the EZ~Brush® Vac Bag Silicone and pour it over the profile. Apply three layers of EZ~Brush® silicone to all surfaces, forming a continuous rubber vacuum bag. Allow all layers to cure. The bag is strong, durable and dimensionally stable.

Step 2: Casting

Use a routered channel to hold the bag in place and ensure perfect vacuum pressure. Spray a resin gel coat over the tool. Use rollers to laminate layers of glass matting with resin. Then, apply release film and a breather. Put the EZ~Brush® vacuum bag into position, securing the edges using the channel routered into the tool in the previous step. Pull the vacuum and check the structure for air leaks.

Step 3: Demold and Finishing

Once the resin has cured, remove the EZ~Brush® bag and store it for future use. The finished part reflects perfect detail and a flawless surface finish. The EZ~Brush® silicone bag cuts production time of the Vapor Optimist by 1/3. This Vapor Optimist sailboat was made by LaserPerformance.
