For interior design, it is difficult to find material better, than ordinary gypsum. And first of all, it is true as for the finishing of walls. Gypsum is ideal material for those who appreciates everything natural and environmentally friendly. And the modern technologies allow turning usual plaster into high-strength, waterproof and really stone-like substance. There are even special compositions on the basis of plaster which can be exploited on the street! The most fashionable types of gypsum facing today are the stone or thin brick laying imitations, various 3D-panels and plaster panels with a relief of wood or tooled leather. Decorative facing manufacturers also like working with plaster compositions. And there is no wonder. It isn't necessary to buy difficult and expensive equipment, as gypsum is very simple in processing. Big floor spaces are of no need, as plaster hardens very quickly. Gypsum is easily colored by different methods and has other numerous advantages. One of the major production moments is the choice of molding forms for for gypsum solutions. In principle, everyone knows the fact that for natural stone reliefs imitation it is necessary to use rubber casting molds. Only they are capable to copy ideally each trifle of a microrelief, to display each crack, a grain of sand and even natural surface characteristic roughness. But rubber molds can be different both as for chemical composition and for the properties. The Zikam Stone Company has 15 years' experience in the field of manufacturing of rubber molds for decorative facing stone and the extensive range of forming equipment in their booklets. The company will gladly share a couple of the useful tips in the right choice of moulds for gypsum casting with you. Moulds for casting of gypsum products can be made of silicone or polyurethane rubber. For example, Zikam Stone makes both these types of molds (depending on production tasks). The principal advantage of silicone molds is that the gypsum doesn't adhere to them at all. It means that in such molds it is possible to mold easily even the cheapest and brittle brands of gypsum. With polyurethane molds this won't do. They require stronger gypsum composites or using special lubrication. By the way, the simplest lubrication for polyurethane molds is ordinary soap solution. Nothing difficult! The advantage of polyurethane gypsum casting molds is their lower cost and insignificant rubber shrinkage. If you need to make plaster panels with excellent geometry and the exact sizes, you need polyurethane molds. And still, there are rubbers which are almost deprived of shortcomings. They hold their shape as well as polyurethane molds, and separate from the hardened gypsum casting as well as silicone molds. However, such rubbers are the most expensive. As you can see, there are important nuances as for the choice of molds for gypsum decors production. They need to be considered if you want to run successful business in this sphere. You can apply for consultation to Zikam Stone experts. They will help you to avoid annoying errors.
