SANDFREE PLASTER (HD)

     

Ever increasing demand for construction sand has caused rapid depletion of riverbeds and raised many environmental concerns. Aggressive and controlled sand mining has resulted in erratic supply and therefore greater fluctuation in prices as well as inconsistency in quality.

Conventional materials and methods of plastering are highly time consuming and involve more operations like procuring and sieving, which in turn lead to spillage and wastage.  

Perlcon Sandfree Plaster is a unique cement based formulation developed specifically to overcome sand related problems like availability, quality, labour and time. Sandfree Plaster ensures consistent quality, fewer operation cycles and quick construction. It saves time and manpower. Self curing Sandfree Plaster also resolves the problem of water for curing.

Sandfree Plaster is a premix material supplied in bags. Apply Sandfree Plaster on walls, ceilings, RCC work by just mixing with water.

Sandfree Plaster is a better alternative to gypsum plaster as it is damp proof, cement based and gives a crack free plaster surface, with quicker application.

How to Apply


 
Fill a clean pot with potable water measuring 18% (+/- 5%) the weight of Sandfree Plaster (1 kg Sandfree Plaster : 0.18 litres water).
Now pour Sandfree Plaster into the pot. Mix and knead slowly to form a homogeneous paste. Let the mixture stand for 10 minutes. Mix the green mortar again without adding more water.
Evenly apply a coat of Sandfree Plaster with a mason’s trowel or with aluminum level patty.
Apply aluminum level patty from bottom to top direction followed by left to right & right to left direction without leaving stroke marks to level the plaster.
 
 
After initial setting apply aluminium scrapping patty to achieve true level and create a rough texture for subsequent coat.
Over smaller area and in corners, apply grilled float to open out plaster surface. Remove loose particles.
After 45 min apply steel/float/muster, if necessary with little sprinkling of water to achieve perfectly leveled plaster surface.
Smooth, leveled, Sandfree Plaster wall is now ready. No curing is required.
