What Is Jesmonite AC100 and How Does It Work?

Jesmonite AC100 is supplied as two components: a water-based acrylic liquid and a mineral base. It is strong, lightweight, and easy to work with and can be used for a variety of projects, from sculpting to construction. Specifically, it can be used as decorative cast objects, rubber mold support cases, polystyrene and foam coatings, rigid molds, and more. In this blog post, we will discuss the properties of Jesmonite AC100 and how it can be used in your next project.

How to Use Jesmonite AC100?

Below are some tips to consider when working with Jesmonite AC100.

• To prepare Jesmonite AC100, the resin and hardening agent are mixed together. The standard mix ratio for AC100 liquids should be one part by weight. For the Jesmonite base, it should be 2.5 parts by weight. Always use an accurate scale and a high-shear mixing blade.
• Mixing: Slowly add the Jesmonite base to the liquids. If you want to add pigment to the mixed Jesmonite, you can try different techniques like swirling it through the mixture. Stir the mixture until it is completely smooth, being careful not to generate any air bubbles. The ratio of powder to liquid can be adjusted to create different textures and effects.
• Casting: Pour the mixture into your mold and coat the surface evenly. Gently tap the mold to remove any air bubbles. Allow it to set for 30-40 minutes. Next, take it out of the mold and let it cure for 24 hours. Once cured, Jesmonite AC100 is strong and durable, yet lightweight and versatile.
• Surface Finish: The surface of Jesmonite AC100 is typically either glossy or matte, depending on the desired look. To achieve a matte finish, the material must be sanded after it has cured. For a glossy finish, a high-gloss sealer can be applied. Jesmonite AC100 is also compatible with a wide range of water-based sealers and varnishes.
• Clean Up: Jesmonite AC100 is very easy to clean up. Simply scrape off any excess product into the bin and then wash your hands, the brushes, and the mold with warm water. Store the remaining Jesmonite in a sealed container to avoid water evaporation.

Is Jesmonite AC100 Waterproof?

Unfortunately, the answer is no. While Jesmonite AC100 is highly resistant to both water and humidity, it is not completely impervious to water because it is classed as porous. If left exposed to constant moisture, Jesmonite will eventually break down.

For this reason, it is important to ensure that any area coated with Jesmonite is properly sealed and protected from the elements.

How to Sand Your Jesmonite AC100 Pieces?

When it comes to sanding Jesmonite AC100, there are a few things to keep in mind in order to get the best results. Depending on the desired surface appearance and texture, you can sand Jesmonite AC100 cured surfaces using different sandpaper grades.

You may want to start with coarse grit sandpaper, working in small sections, then you can then switch to a finer sandpaper to finish the job. Make sure to wipe away any dust after sanding in order to get a smooth, even finish.
