Discover the ultimate solution for releasing concrete or gypsum plaster castings from rubber molds with Smooth-On's In & Out II water soluble release agent. This versatile and economical product provides a clean, positive release without interfering with surface detail or affecting color pigmenting of cast concrete. In & Out II minimizes the formation of "bug holes" in concrete and air bubbles in gypsum castings, ensuring a smooth and flawless finish.

The secret to In & Out II's success lies in its unique formula, which is easy to mix with water and apply using a brush, roller, or spray. With a recommended dilution ratio of 4 parts water to 1 part In & Out II, you can achieve optimal results. For more challenging applications, you can adjust the ratio to 2 parts water to 1 part release agent. The key to success lies in mixing only the amount needed for one day, as the mixture may separate after 24 hours.

To ensure a uniform application, it's essential to apply In & Out II thoroughly and evenly. Using a pressure sprayer with a flat spray tip can help achieve a consistent coat. However, it's crucial to avoid over-applying the release agent, as this can lead to unwanted air bubbles, "wormtracks," and pitting on the surface. A small test application is always recommended to determine the suitability of In & Out II for your specific project.

One of the significant advantages of In & Out II is its ability to keep molds clean and minimize the buildup of residue. This feature significantly extends the life of your molds and reduces maintenance costs. The non-staining and non-softening properties of In & Out II also ensure that your concrete surfaces remain unaffected.
