Due to popular demand, Jesmonite has reformulated and re-released its Acrylic Sealer! 


Jesmonite® Acrylic Sealer is a pure acrylic coating compatible with AC100, AC200 & AC300 to add increased water resistance. It’s 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 a brush, roller, or spray.

Jesmonite recommends 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 Jesmonite Liquid Pigments to create colour washes to add a patina or to artificially age casts.
