PROTECTA®EX Mortar system consists of rockwool boards: melting temperature 1000° C, thickness 50 mm, density 150 kg/m³ and Gypsum plasster. Gypsum plaster maintenance time in liquid form can be extended by using Protecta EX Retarder powder.

PROTECTA®EX Gypsum Plaster is a dry white powder consisting of inorganic compounds and perlite. When mixed with water, the compounds form a highlly insulating fire sealing compound to prevent the spread of fire and smoke through openings in fire rated walls and floors, including openings formed around building service penetrations.

PROTECTA®EX Gypsum Plaster expands approx 1% by hydraulic action during curing ensuring a very tight seal around the service penetrations and the surrounding opening apertures.

PROTECTA®EX Gypsum Plaster is easy to sand or drill. The compound dries to an off-white colour which may be painted.
