Characteristics and application areas :
Siva is a gypsum plaster applied by spray machine which is used for plastering of various kinds of construction materials such as bricks, cement blocks, light cement blocks and concrete covered surfaces.
Main advantage of using Makina Siva spray gypsum is its fast implementation(4 to 5 times more hand applied gypsums), beside this, by using perlite and polymer based compounds in this production, it has advantages of long setting time, light weight, and more sound and heat proof resistance in comparison to ordinary gypsum (for obtaining a smooth finish layer, saten gypsum should be used as the finishing layer).
Preparation of Mortar and instructions:
Fill the container of gypsum spray machine with gypsum and water in ratio of 20 liter of water per each 30 kg bag of gypsum .after mixing of the material by the machine, spray the mixture on the wall and level it after 15 minutes. 1 hour later, moisture the surface with a sponge trowel and finish it with a aluminum or steel trowel.
