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 Stopseal Batt and the site conditions are within the application specification
• Measure the size of the opening, relevant position and the size of the services. Mask all surfaces where necessary to ensure the aesthetics of Pyrocoustic Sealant
• Draw these details onto the Stopseal Batt and cut out using a suitable saw
• Using a trowel or pallet knife apply a thick layer of Pyrocoustic Sealant to all areas of contact around the opening and services. Apply a similar thickness of Pyrocoustic Sealant to all of the edges of the cut Stopseal Batt
• Fit the cut Stopseal Batt into the opening, ensuring a tight friction fit
• Push the Stopseal Batt firmly into the opening using the flat of the hand. Continue the above procedure to fill the opening ensuring that a layer of Pyrocoustic Sealant is applied to all areas of contact between the boards. The seal should be made up from a few pieces of Stopseal Batt as practicable
• Any small gaps in the seal left when all cut pieces have been installed should be tightly packed with off-cuts and coated with Pyrocoustic Sealant. A layer of Pyrocoustic Sealant should be applied to all joint lines formed
• To complete the installation a small bead of Pyrocoustic Sealant should be applied around the extremities of the opening and services. Whatever the edges of the seal line with the wall/floor surface, the bead of Pyrocoustic Sealant should be smoothed to overlap the wall/floor surface by approx. 5mm
• A Stopseal double Batt system may have a requirement for structural supports, they should be steel back to back angles circa 40mm x 40mm x 1.2mm thickness. All joints to be off-set or staggered
