Vermiculite Plasters

Vermiculite plasters can be made with either gypsum or Portland cement. The advantage which all types of vermiculite plasters have over conventional types of plasters are:

improved coverage
lighter weight
improved workability
excellent fire resistance
reduced thermal conductivity
improved adhesion to a wide range of backgrounds
increased resistance to cracking and shrinkage

Vermiculite also improves the resistance to chipping of plasters due to the ability of vermiculite particles to accommodate dimensional change.

Vermiculite plasters, whether gypsum or cement based, can be applied by hand or by spraying machine. Being a non-abrasive aggregate, vermiculite is well suited to spray application and the sprayed plasters can have an attractive decorative appearance.
