Gypsum Powder is processed through the plaster breaking, calcined and grinding aging System in Nepal. Gypsum rock is mined or quarried and then crushed. The crushed rock is then ground into a fine powder and heated to about 350 degrees F, driving off three fourths of the chemically combined water in a process called calcining. Gypsum selection and preparation (cleaning, classifying) are key factors to produce the best powder. HOMEMANDU GypPowder not only promises strength but also caters to aesthetic appeal by being whiter in color, with 98% purity level a fact that has been tested and approved.
HOMEMANDU GypPlaster, Plaster of Paris is a fine white powder it is referred to the form of gypsum which has been heated to a high temperature to drive off the water in its crystal structure. Gypsum selection and preparation (cleaning, classifying) are key factors to produce the best plasters of Paris, and the performance of the powder depends a lot on its crystals’ sizes and shapes.
GypPlaster® is highly versatile and can be used for various residential and commercial applications such as: internal plastering, making casts for statuary, ceramics, dental plates, fine metal parts for precision instruments, and surgical splints. It is superior material to other alternatives for the internal plastering of all structure, this System in Nepal replaces sand and cement master.
Special fertilizer grade is also available.
