PLASTERING
Taken from : Ambuja Technical Literature Series - 36
INTRODUCTION
Plastering is a process of applying one or more coats of mortar to a concrete surface, brickwork, stone masonry or lathing. It must be durable such that it
resists the penetration of moisture and should be able to weather uniformly. It should also be pleasing in appearance. These properties depend upon materials used, composition of mix, degree of mechanical bond between the plaster and the backing surface and workmanship. Lack of bond with the backing, cracking, crazing of surface and discoloration are principal defects in plastering. Sufficient care has to be taken to overcome these defects.
TECHNICAL TERMS USED
Background - The surface to which the first coat of plaster is applied.
Blistering - The development of defect in the form of one or more loose swellings on the finished plastered surface.
Cracking - The development of one or more fissures in the plaster surface. This can happen due to several reasons.
Crazing - The development of a series of minute hair cracks in an irregular closely spaced pattern over the finished surface.
Dado - This is the lower part of the plastered wall (up to 1.5 meter above floor) which is made more resistance than the upper part in order to protect it
Tools for Plastering
