Everbuild Everflex AC95 Intumescent Acoustic Sealant and Adhesive extended informationSlump Resistance :No slump at 25 °C when placed in a 20 mm x 10mm vertical channel.Application Temp Range: 5 °C to 40 °CCompatibility: Can be used in contact with most building and decorating materials but should not be used against bituminous materials.APPLICATION INFORMATIONCuring Time1 to 5 days, dependent on thickness, ambient temperature and humidity.Tack Free Time15 to 60 mins, dependent on thickness, ambient temperature and humid- ity.Everbuild Everflex AC95 Technical InformationShore A HardnessApproximately 40.Movement CapabilityLow ( /- 5 %)Service Temperature-15 °C to 70 °CChemical ResistanceDilute Acids - Fair Aliphatic Hydrocarbons - Fair Dilute Alkaline - Fair Aromatic Hydrocarbons - PoorAPPLICATION INSTRUCTIONSSUBSTRATE PREPARATIONAll 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 501 PVA Bond diluted 1:4 with water. Surfaces may be slightly damp, but not wet. NOTE: THIS WILL SLOW THE CURE.APPLICATION METHOD / TOOLSFit cartridge into a 1 L 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 9-10 mm diameter, pierce inner membrane and apply a continuous bead to one surface at 250-350 mm centres. 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.Everbuild AC95 LimitationsDamp 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 5 °C.For overhead boarding applications, always use in conjunction with mechanical fixings.Known to have compatibility problems with some cPVC piping.
