The Jesmonite Acrylic Sealer is used with Jesmonite AC100 and provides Increased Water Resistance when your project is used externally. It can also be pigmented and used as a Colour Wash to add a Patina or to Artificially Age Casts and Project Pieces.
Jesmonite® Acrylic Sealer is a pure acrylic coating compatible with AC100, 200 & 300. Its a durable, flexible product designed for use in a variety of applications. The new formulation is designed to ensure the matte appearance of Jesmonite is maintained whilst also being easily applied using brush, roller, or spray.
Products sealed with Acrylic Sealer will require re-coating at 6-to-10-year intervals, to ensure optimal results. Please be aware that when used in conjunction with AC200 and AC300 you will not receive the same level of protection when used externally.
Application
We recommend for best results that two coats of Acrylic Sealer should be applied onto low porosity surfaces such as AC100, with the first coat being diluted with 10 20% water. Diluting the first coat will aid the chemical bonding process of the Acrylic Sealer.
The second proprietary coat is applied once the initial diluted coat is touch dry. Do not allow the first coat to dry completely before applying the second coat. In principle the application of several thin coats is preferable to one thick coat.
Remember that Acrylic Sealer goes a long way, therefore small quantities can cover large areas do not over apply the product and ensure you work with small doses to control the process.
Acrylic Sealer can also be diluted with water and pigmented using the Jesmonite Liquid Pigments to create colour washes to add a patina or to artificially age casts.
