AC730

Jesmonite AC730 is the most appropriate material solution for water features.

Jesmonite Flexiguard Sealer is the most appropriate Jesmonite sealer for Jesmonite AC730 surfaces. The Jesmonite Flexiguard Sealer is a solvent-free, nano based technology. This sealer is designed for stain resistance and offers an invisible surface effect. The Jesmonite Flexiguard Sealer achieves a protective layer less than 100-nm thick which bonds with the inner pores of the AC730 substrate.

The most appropriate Jesmonite material for a decorative splash is Jesmonite AC730. Jesmonite AC730 achieves an A2-s1-d0 EN13501-1 (non-combustible) Fire Classification. 

Jesmonite AC730 cured surfaces can be sanded using a variety of sandpaper grades to reveal decorative aggregates and achieve a range of different surface appearances and textures. Most users will start with a coarse sandpaper and then move onto a fine sandpaper grade for finer finishing. The sanding process can be done by hand or with a power sander.

AC100

Jesmonite AC100 would be best suited for lightweight jewellery.

The setting time can be anything between 50 minutes and 2 hours, depending on temperature in the room.

Jesmonite Acrylic Sealer is the most appropriate sealer for Jesmonite AC100 surfaces. The Jesmonite Acrylic Sealer is a pure acrylic coating. We recommend applying the Jesmonite Acrylic Sealer onto Jesmonite AC100 surface with a dense foam roller rather than low density foam and traditional paint rollers. The low density foam and traditional paint rollers can leave streaks where the Jesmonite Acrylic Sealer builds up unevenly on the ends of the rollers.

The Jesmonite Thixotrope is added to the Jesmonite AC100 mix to thicken the material to a ‘gel-coat’ consistency. This is useful when brushing or spraying materials onto moulds with vertical faces as it prevents the material from slumping. Jesmonite Thixotrope is added to the complete Jesmonite AC100 mixture and is mixed in using the Jesmonite High-Shear Mixing Blade. Add drop by drop until the desired consistency is achieved. Typical inclusion rates by weight are 2g–6g per kg (0.2-0.6%) of complete Jesmonite AC100 mix.
