You will also require Jumbo Sealant Gun.
Benefits
- Forms a fire rated acoustic barrier - up to 5 hour fire rating - 25% greater than conventional/competitive fire rated sealants
- Permanently flexible/high grab
- Adheres to most surfaces
- Mould resistant
- Non flammable
- Overpaintable
- Easy clean up
- Approx. 32 linear meters of coverage for a 6mm diameter bead.
Areas For Use
- To form an acoustic and intumescent barrier by sealing gaps between plasterboard walls, floors and ceilings and dry lining applications.
- As an adhesive to bond plasterboard to plasterboard and to bond plasterboard to wood and metal studding and direct to block work.
- For sealing and bonding most other kraft lined insulation boards.
Limitations
- Damp or humid conditions will significantly extend the cure time.
- Do not attempt to abrade when cured.
- Do not overpaint until product has fully cured. This will normally be 24 hours but may be 4-5 days in damp, cold or humid conditions.
- Do not apply below 5øC.
- For overhead boarding applications, always use in conjunction with mechanical fixings.
Surface Preparation
All surfaces must be clean and dust free. All loose or flaking surface coatings, and old sealant and mastic joints, should be removed before application. Highly porous substrates such as new plaster should first be primed with Everbuild PVA bond diluted 1:4 with water. Surfaces may be slightly damp, but not wet. NOTE: THIS WILL SLOW THE CURE.
Application
Fit cartridge into a 1ltr mastic gun. Cut nozzle to required length and puncture inner membrane seal before applying.
Use as a sealant: Always cut nozzle to a size slightly larger than the gap to be sealed.. Apply to gap, slightly overfilling and finish smooth with a caulking tool or filler knife. Clean up any excess with a damp cloth within 30 minutes of application.
Use as an adhesive for direct bonding to large surfaces: Cut nozzle to provide a bead of approximately 9-10mm diameter, pierce inner membrane and apply a continuous bead to one surface at 250-350mm centers. Apply board immediately to surface and tamp down. Provide temporary support until cured.
Use as an adhesive for bonding to studding: Apply a continuous bead to studding and apply board immediately into position. Do not apply more than one board?s width of studding at one time. Provide temporary support until cured.
