The Jesmonite silicone mold for letters and numbers is a self-separating, reusable casting mold made of flexible silicone that is used to produce three-dimensional letters. It is suitable for various casting compounds such as Jesmonite, concrete, plaster or other casting compounds and enables numerous casting processes. The service life of the mold depends on the aggressiveness of the casting material. Solvent-based casting compounds stress the mold more than plaster-based or wax-based casting compounds.
Please note: Dark colors or pigments in the casting compound can leave marks on the silicone mold. Transport and packaging-related irregularities can usually be rectified by kneading or massaging in hot water and are not grounds for complaint.
You can use the mold to make individual letters and numbers that are suitable for decorative lettering. Homemade letters and numbers are suitable for birthdays and anniversaries that you want to make a little extra special. Experiment with different casting compounds and pigments to achieve unique color and texture effects.
If possible, clean the silicone mold after each use with warm water and mild detergent. Then dry it thoroughly so that it lasts as long as possible. Store the mold in a dust-free place to avoid soiling, which could affect the quality of future casting projects. If you are not using the mold for a longer period of time, it is best to store it lined with a non-aggressive material such as plaster.
