One Step™

Description

This liquid product functions as both a sealing and release agent in one application. Its non-flammable, non-VOC formula removes the need for separate sealers and release agents when working with urethane mold rubbers, simplifying the mold-making process and saving time.

Designed for superior performance, it effectively seals porous surfaces while ensuring a clean release of cured urethane rubber molds from materials like plaster, concrete, stone, brick, marble, limestone, wood, and metal. It forms a durable barrier that prevents bonding and surface damage, resulting in high-quality molds and castings with fine detail and smooth finishes.

The liquid applies easily with a brush, cloth, or spray, drying quickly to create an even, non-tacky surface ready for molding. It is valued for its ease of use, cost efficiency, and consistent results across different substrates. However, it is not recommended for use on modeling clays, as it may interfere with their surface properties. It is suitable for artists, fabricators, and industrial mold makers seeking a reliable all-in-one sealing and release solution.

Instructions

Safety

• Work in a well-ventilated area.
• Wear safety glasses, long sleeves, and rubber gloves.
• Work in low humidity environments to aid solvent evaporation.
• Ensure the surface is clean, dry, and free of dust.
• Shake the container thoroughly before each use.

Store and use the material at room temperature (23°C/73°F).

Application

• Use a dry brush to apply a thin, even layer over the entire surface of the model and any areas that will contact the mold rubber.
• Brush into deep details and undercuts on the model.
• Avoid pooling; use compressed air to remove excess.
• Allow to dry for 15 minutes, then apply a second coat and let dry for 30 minutes.
• Mix and apply the urethane rubber as per the instructions in the rubber product technical bulletin.
• For extremely porous surfaces like pressed brick, apply three coats before applying the mold rubber.
• Conduct a small test application to ensure suitability for your project if there are any performance concerns.
