Protecta EX Mortar
EX Mortar is a dry, white powder composed of inorganic materials and perlite that, when mixed with water, forms a highly effective thermal insulating and fire-sealing compound. Assessed to AS1530.4-2014 and AS4072.1-2005 standards, this product is designed to prevent the spread of fire and smoke through openings in fire-rated walls and floors around building penetrations, while also maintaining acoustic performance. During curing, EX Mortar expands approximately 1% through hydraulic action, ensuring a tight, durable seal around service penetrations and surrounding apertures. Once set, it forms an off-white, sandable, and drillable compound with a density of approximately 1050 kg/m³. It adheres well to most surfaces, including concrete, brick, steel, and plastic, though it is not suitable for doors or service openings subject to movement. Priming is generally not required, but any metal services in contact with the seal must be corrosion protected.
