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. Simplify Your Production Casting With IN & OUT II.

Will Not Stain / Soften Concrete Or Gypsum Surfaces
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

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.

So-Cure Urethane Accelerator

SO-CURE Cure Accelerator is an additive designed to "accelerate" the cure time of some Smooth-On urethane liquid plastic products without significantly affecting ultimate physical properties. This allows for much faster Demolding of a part or casting from a mold. The accelerator is added to Part B by weight and should be thoroughly mixed with Part B before adding Part A. Important: Adding the accelerator drastically reduces the Pot Life (time you have to mix and pour material) of the liquid plastic product. This product is not for use with Clear Urethanes.
