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.
