SuperSeal-Sealing Agent

Super Seal was developed as an economical, fast drying sealant agent for a variety of surfaced including modeling clays, gypsum plasters, concrete and wood. THe sealing agent will quickly and effectively seal surfaced without interfering with the surface detail. Mold rubber (polyurethane, silicone pr Polysulfides) can then be applied.
The Advantages of Using SuperSeal
  • Low Cost
  • Low Viscosity - wets out well over any surface
  • Evaporates Quickly
  • Ultra Thin Film - does not interfere with reproduction of surface detail or finish. Gives cured rubber mold surface a smooth, satin finish.
  • Removable - can be rinsed from model surface with warm water.
Directions - Applying SuperSeal
A minimum of 2 coats of SuperSeal is recommended to seal most surfaced. For extremely porous surfaces (ie. Limestone) and additional coat of SuperSeal may be required. Or apply two coats of SuperSeal and follow with an application of Universal Mold Release Agent.
SuperSeal can be applies using a soft brush or a non-aerosol spray bottle to lightly mist SuperSeal onto model.
  1. Apply a thorough coating of SuperSeal over entire model surface ad surrounding forms including intricate detail and undercuts. Compressed air or a hair dryer may be used to blow off any excess that has pooled. Let dry for 5 minutes.
  2. Repeat above 1 -2 more times and let final coat dry for at least 2 hours.
  3. If recommended by mold rubber manufacturer, apply a light mist coating of release agent (i.e Universal Mold Release).
IMPORTANT: Discoloration of model surface may occur. If compatibility between SuperSeal and model surface or SuperSeal and a particular mold rubber, a small scale teat should be made on an identical surface.
