In & Out™II Concrete Release Agent | Reynolds Advanced Materials

IN & OUT™ II water soluble release agent will aid in releasing concrete or gypsum plaster castings from Smooth-On rubber molds. IN & OUT™ II provides a clean, positive release and does not interfere with or affect surface detail and helps minimize air bubbles in finished castings.

IN & OUT™ II Water Soluble Release Agent IN & OUT™ II IS DILUTED WITH WATER. Mix 4 parts water to 1 part In & Out™ II. Mixing can be done by hand or slow speed mixer. Do not shake or agitate as this may cause product to foam. How you dilute IN & OUT™ II (amount mixed with water, coverage and frequency of application) will depend on the concrete aggregate mix and the form material you are casting into. For example, when casting concrete with a low grit/high sand content (minimal abrasion) into a polyurethane mold, the mix ratio of water to IN & OUT II™ can be 4 : 1. High grit content may call for a dilution ratio of 2 parts water to 1 part release agent. Mix only amount needed for one day. Mixture may separate after 24 hours. Re-mix to a uniform consistency and apply.
