Unlike ordinary sand plaster which can expand and explode during fires and/or when subjected to high temperatures. Vishal one coat plaster have low linear expansion characteristics which greatly reduce the number and size of cracks. By reducing the number and size of cracks through the plaster,the heat and flames, perlite release chemically combined water in form of water has been driven off as steam. Meanwhile the insulating action of the perlite aggergates delays the release of steam and retards the transmission of heat , thus improving overall fire – proofing characteristics.
Application
The Ligthness, compatibility and low water requirementsof Vishal on coat makes it adaptables for use with most plastering machine. Over monolithic concrete, The thickness of vishal one coat plaster shall not exceed 31/8 in.(10 mm) on ceiling and 51/8in.(16 mm) on walls.
Setting Time
Plastering specification usually require that gypsum based coated plaster have a setting time pf not more than four hours. Slow setting plaster result in a weak base coat. excessive drying shrinkage and needless finish coat fractures. Vishal one coat used in these application has a set time of approximately 35-45 minute after mixing.
Lightweight
Weighs approximately 54% less than the ordinary sand plaster.Saving about 900kg for every 89.sq.mt. of Material applied with 13mm thick coat.
