Used on low suction backgrounds where increased adhesion is required, e.g. concrete plasterboard) or on surfaces treated with a PVA bonding agent.  (e.g. sound painted brickwork).

Plastalite Plasters can be used adjacent to heritage type plasters (e.g. sand and lime based) or modern type plasters (e.g. cement or gypsum based) without detriment.
