Specifically designed for composite molders who prefer to spray on mold release.
- Application Method
- Immediately before molding, make sure that the mold is dust free. Spray 858 using a High Volume Low Pressure type spray gun, such as those by Binks, AccuSpray, or DeVilbiss. The release should go on wet without puddling.
- Recommended settings: Fluid Pressure – 3-8 psi
- Air Pressure – 35-55 psi
- Fluid nozzle = 1.0-1.88mm
- Strokes should overlap slightly to assure complete coverage. Adjust air and liquid controls to provide a light, uniform film, the film should be visible as a wet coating for 6 – 12 inches behind the spray application. Keep the spray nozzle @ 6 – 15 inches from the mold surface. An air pressure setting in the 30 – 40 psi range should reduce any fogging effect. Adjust air and liquid controls to maintain a uniform spray pattern, lower air pressure produces a wetter film that is easier to see and may be useful in applying to more difficult areas of the mold surface. The spray gun itself should have the fluid knob set to ½ to 1 full turn open from the closed position.
- Spray successive coats of release, working each coat at a right angle to the previous one to cover the entire mold surface. For those deep or complicated surface areas where spraying can be difficult we recommend wiping on 1 – 2 coats of 858. Apply with a clean, woven, lint free cloth, such as the Scott Shop Towels On A Roll, Kimberly-Clark WorkHorse rags or WypAll wipes, or a heavy-duty plain white paper towel, followed by the spray application. It is always a good idea to wipe on the initial coat of 858 to assure even coverage of the mold surface.
- 4-5 coats are recommended although new or porous tooling may require as many as 6 coats. Typically, 1 gallon of 858 will cover an area of 200 – 250 sq. ft on a seasoned mold. Allow each coat to flash dry before applying the next coat. It is always a good idea to apply an extra coat or two to high wear areas where shear forces or abrasion will most impact release performance. Following your final coat of 858 allow 30 minutes for the release to cure before using the mold. Hot and humid conditions can affect the drying time of the spray and may require adjustment of settings to insure a uniform spray.
- When spraying a large mold that requires walking on the surface, apply the release to a section at a time.
- Apply all of your coats and allow a minimum of one hour of cure time prior to molding.
- Immediately before molding, make sure that the mold is dust free. Spray 858 using a High Volume Low Pressure type spray gun, such as those by Binks, AccuSpray, or DeVilbiss. The release should go on wet without puddling.

Storage & Handling
- Maintenance & Touch-up
Promptly touch-up any areas, which are difficult to release or subject to abrasion. If no residue is present, simply apply more XTEND 858. If there is minimal buildup, clean the mold by lightly wiping with a cloth that is just damp with CX-500 and then apply additional coats of release.
