IN & OUT II water soluble release agent will aid in releasing concrete or gypsum plaster castings from Smooth-On rubber molds. Provides a clean, positive release and does not interfere with or affect surface detail and helps minimize air bubbles in finished castings. Properties Simplify Your Production Casting With IN & OUT II Will Not Stain / Soften Concrete Or Gypsum Surface.Mix With Water - Economical.Will Not Affect Color Pigmenting Of Cast Concrete.Minimizes "Bug Holes" In Concrete And Air Bubbles In Gypsum Castings.Keeps Molds Clean - Does Not Build Up.Significantly Extends Mold Life. Directions Store at room temperature (72F / 23C). Do not use below 50F / 10C. This product has a limited shelf life and should be used as soon as possible. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Application Apply IN & OUT II thoroughly with brush, roller or spray. If pressure spraying, pressure should be 25 psi (172 kPa) or higher. For uniform spray applications of release agent, flat spray tips are suggested. Do not allow release agent to puddle. Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if perfor-mance of this material is in question. Do Not Over Apply. Applying too much release agent will cause air bubbles "wormtracks", "bugholes" or pitting on surfaces.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.Documentation Technical Bulletin
