The Pyrocrete Mortar 239 is a medium-densitycement-based product developed specifically for passive fire protection of structural steel, roofs, wood and concrete structures. .

The mortar is tested at Underwriters Laboratories Inc. in the United States, according to different test procedures under UL and ASTM standards (sound insulation). It is suitable for both interior and exterior use.

This mortar provides a fire resistance of up to 240 minutes and a sound absorption coefficient (NRC) of up to 0.75.

Pyrocrete 239 is applied using the wet method, with a worm gear machine. To be able to carry out the application we must prepare the surface and place a mesh in place if the constructive design so requires.

First of all, we must check that the surface is free of oil, grease, dust or any other substance that could prevent the correct adherence of the system. After checking the surface, a primer is used if required. No primer is required for application on galvanized steel, but if required, contact the technical department to use a primer that is compatible.

Depending on the thickness of application, the product will be sprayed in one or more layers, not exceeding 12.5 mm for the first layer. The time between layers should be between 1-2 hours and should not exceed 24 hours.

The Pyrocrete 239 mortar can be smoothed for improved aesthetics and can be finished using paint, applying a coat of Carboguard 1340 plus the subsequent application of an additional coat of Carbothane 134 Series.
