Preparation
Ensure you use an accurate scale and a high-shear Jesmonite® mixing blade to ensure the compound meets its specifications.
The workshop should be warm, dry, and out of direct sunlight. Environments where solvent-based compounds are regularly used should be avoided. Mixing containers must be clean, dry and of an appropriate size.
Mixing ratio
1 : 2.5
i.e., 100g of liquid to 250g of powder
Mixing & adding pigment
For a solid color, mix the pigment into the pre-weighed AC100 liquid, stir thoroughly, and slowly add the Jesmonite® base to the liquid while mixing until the mixture is smooth, fluid, and lump-free.
For a marbled/irregular effect, add the pigment to the mixture (powder+liquid), swirling it to create different effects.
The standard addition rate is 2% of the total weight of the Jesmonite® mixture. (Too much pigment will prevent the Jesmonite® from setting or will make the molded object weak and brittle).
Molding
For a simple casting, pour a small amount of the mixture into the mold and coat the surface evenly.
To avoid any air bubbles on the surface, use a small clean, dry brush to evenly coat the surface and get into the edges of the mold.
You can also tap the mold to remove surface air bubbles. Then, fill the mold with the rest of the Jesmonite® mixture.
Gently tap the mold to bring air bubbles to the surface. Then, let your mold cure for 30 to 40 minutes.
Once demolded, your piece will reach full strength after 24 hours. Jesmonite® needs all moisture to evaporate. If you leave your piece in the mold, it will sweat, may mark and may not dry completely.
Finish
Jesmonite® AC100 contains a high-quality pure acrylic resin that can be polished with a clean cotton cloth. Excellent results can be achieved with a wide range of waxes and polishing machines, and Jesmonite® AC100 is also compatible with a wide range of water-based sealers and varnishes.
Storage
As a general rule, liquid containers should be tightly sealed to prevent water evaporation and skin formation.
They should be stored at a constant temperature between 5 and 25°C and used within twelve months of the manufacturing date.
The base should be kept dry and stored at a temperature between 5 and 25°C. It must be used within 12 months of the date of manufacture.
Cleaning
As Jesmonite® is water-based, it is easy to clean once you are finished. Scrape any excess unused Jesmonite® into the bin, then wash your hands, mixing pots, brushes, and the mold with warm soapy water. It’s that easy! You can use White Spirit to remove any pigment residue from your mold if necessary.
