Flexi-Coat Sealant is a highly flexible water based, acrylic coating used in linear gaps where voids are present in floor and wall constructions as well as service penetrations to reinstate the fire-resistant performance. The Flexi-Coat Sealant is supplied in liquid form contained within 5kg, 10kg, 20kg, 25kg pails.
The Flexi-Coat system offers excellent movement and acoustic capabilities. Flexi-Coat can offer up to 50% movement. Flexi-Coat can be poured, trowelled or sprayed into the aperture between the separating elements to a specified depth utilising stone wool backing material.
Tested with Metallic Pipes, Cables, Cable Bunches, Cable Trays and Cable Ladders
Causes no known effect to plastic pipes, plastic cables, sheathing or metallic components
Joint movement capability of +/- 50% -10 to +95°C
Dynamic movement testing 500 cycles per 30 minutes
Highly flexible and water resistant
Halogen free, resists fungi and vermin
Can be spray, brush, pour or trowel applied
Ideal for slab edge applications and head of wall and movement installations or where movement is expected in service penetrations
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 and masonry, no priming required, though refer to substrate compatibility requirements
Ensure that the aperture and services in question are tested with Flexi-Coat and the site conditions are within the application specification
Upon installation make sure that you install the minimum 80kg/m³ stone wool with a minimum 20% compression between substrates and or around services, ensuring a tight compression fit
Fit around all services effectively, brush or trowel Flexi-Coat over the stone wool ensuring all joints are fully covered to the minimum required Flexi-Coat thickness
Ensure Flexi-Coat is overlapped onto substrates or services by minimum 20mm when coating
Ensure Flexi-Coat is applied to a minimum
DFT (Dry Film Thickness) of 1mm (2.5mm Wet Film Thickness)
