Plaster Slab Partitions

Plaster slabs or plaster boards are made from burnt gypsum or plaster of paris, mixed with sawdust or other fibrous material to reduce its weight. They are cast in moulds of size 1 to 2m long, 30cm high and 50 to 100mm thick. The surfaces of these slabs may be smooth or rough. Rough surfaces serve as key for plaster. Smooth surfaces are not plastered.
