    Description

    FSi Pyropro LST is an acrylic based sealant used to reinstate the fire resistance performance of wall and floor constructions where they have been provided with apertures for the penetrations of multiple services. Also forms linear gap seals where gaps are present within the wall and floor constructions and linear joints where wall and floor constructions abutt.

    PyroProLST Fire Resistant Sealant is a water based acrylic sealant which has been developed utilising specialist materials which significantly reduce smoke and toxic fumes in the event of a fire, PyroProLST therefore is authorised for use on the London Underground network, and other underground/ tunnel networks.

    Pyropro LST has slight intumescent properties that cause it to swell upon heating.

    The sealant is either gunned or trowelled into the aperture in or between the separating element/elements to a specific depth utilising various backing materials.

    Compatibility

    FSi ensure their systems are manufactured to the highest standards; before installation takes place, would recommend a compatibility check is done. Constituents found in some coatings, such as intumescent paints, adhesives, sealants and residues of those materials may affect the product.

    Priming is not required with most construction materials but porous surfaces should be primed with a PVA Adhesive.



    Backing Material


    Stonewool (min. 80kg/m3) or PE backing rod where required can be use as backing materials, though the Pyropro LST should be installed correctly to achieve the performance needed.



    Key Installation Points


    For good adhesion the surfaces of the building elements shall be free of any dust or grease and may need to be primed, on good clean, virgin concrete & masonry, no priming required.

    Ensure that the aperture and services in question are tested with Pyropro LST and the site conditions are within the application specification. An annular space needs to be present around the service to apply sufficient installation depth.

    All services and apertures need to be clean and clear of all dust and loose particles. The aperture temperature needs to at 5℃ or above at time of installation.

    Upon installation make sure that you install the Pyropro LST around all services needed.

    Once compacted, smooth off the Pyropro LST to produce a professional finish.
