APPLICATION INSTRUCTIONSPREPARATIONClean all surfaces by removing foreign matter andcontaminants such as oil, dust, grease, frost, water,surface dirt, old sealants and any protective coating.Porous substrates should be cleaned by grinding sawcutting or blast cleaning (sand or water). Dust, looseparticles, etc should be blown out of joints with oil freecompressed air or vacuum cleaned. Non-porous andplastic surfaces should be cleaned by solvent ormechanical means. Cleaning solvents should not beallowed to air dry or evaporate without being wiped with aclean, dry cloth.PRIMINGIn non-fabrication applications Seal 'N' Flex FC generallydoes not require priming. For maximum performance onporous surfaces use Bostik N49 Primer and/or BondflexPrimer. N40 Primer and 5077 cleaner / primer isrecommended for non-porous surfaces. On applicationsinvolving glass, specially treated surfaces or criticalstructural fabrications consult Bostik for primerrecommendations.MIXINGNo mixing is required for Bostik Seal ‘N’ Flex FC. Simplyuse directly from sausage or cartridge.APPLICATIONSeal 'N' Flex FC when used as an adhesive or sealantshould be dispensed from either the cartridge or sausagesachet by means of a hand or air operated caulking gundesigned for such application (available from Bostik).Pierce the membrane from the top of the cartridge andscrew on the supplied nozzle. Having previously cut thisto give the required angle and bead size.Place the cartridge in a suitable Bostik extrusion gun andpress the trigger. For sausages, a barrel gun is required,this is available from Bostik. Clip the end of the sausageand place complete sausage with pierced end located atthe top of the nozzle. Screw top of nozzle and housing onbarrel of gun. Using the trigger on the gun extrudeproduct from the sausage to stop product flow, using thethumb depress the catch plate mechanism located at thevery rear of the gun, directly above the trigger.Apply Seal 'N' Flex FC in a continuous operation usingpositive pressure adequate to properly fill and seal acavity.Construction Adhesive ApplicationsSeal 'N' Flex FC does not need to be applied to bothsurfaces to be bonded, but both surfaces must beprepared in accordance with preparatory work.Apply in beads or daubs to the prepared substrate.Materials being adhered can be bonded immediately orleft open for up to 15 minutes after application prior tobonding. If no mechanical fixing is to be used inconjunction with adhesive, clamping is necessary until fullcure is achieved.Use only enough sealant to achieve adequate bond(dependant on surface texture). Excess sealant can beremoved by dry cloth or solvent wipe before curing. Ifadhesive is to be exposed, smooth off with spatula orputty knife to flush finish.Construction Sealant/Adhesive ApplicationsSeal 'N' Flex FC is especially suitable for vertical jointsealing or in flooring applications such as saw cutjointing.More joint movement can be accommodated in a thinbead of sealant than in a thick bead. The ratio of jointwidth of sealant to depth should be 2:1. The use of abond breaker prevents undesirable three-sided adhesion.Open cell polyurethane foam or closed cell polyethylenefoam rod is the recommended backup material to controlcorrect sealant geometry.Install back up material or joint filler, as specified. ApplySeal 'N' Flex FC continuously using positive pressure toproperly fill and seal the joint. Tool the sealant withadequate pressure to spread the sealant against the backup material and onto the joint sides. Excess sealantshould be wiped from all surfaces while still uncured.Remove any masking tapes prior to sealant curing.CLEAN-UPClean up uncured material and equipment immediatelyafter use using Bostik 9907 solvent. Do not use solventson skins.For removal on skin, uncured sealant can be removedwith Bostik Hand-Clean towels. Cured Seal ‘N’ Flex FC isdifficult to remove via chemical means and mechanicalmeans may be necessary.PACKAGINGBostik Seal ‘N’ Flex FC is supplied in 300ml cartridgesand 600ml sausages, 20 per carton.COVERAGEThe coverage below is the approximate linear metrecoverage per pack size.SIZE6mmx6mm10mmx10mm20mmx10mm300ml (ctg) 8.3 3 1.5600ml (ssg) 16.7 6 3Calculation formulaW x D X L = Litres1000W = Width(mm) D = Depth(mm) L= Length(metres)SEAL ‘N’ FLEX FC PAGE 2 of 3.

All materialsshould be stored under cover in a manner that willprevent damage preferably on pallets.PRECAUTION• Seal ‘N’ Flex FC is not recommended for use insealing joints or bonding fabrications subject toconstant immersion in seawater or where abrasionor physical abuse is encountered.• Seal 'N' Flex FC should not be used in highlychlorinated areas such as swimming pools, spas etcwithout prior consultation with Bostik TechnicalServices.• Seal 'N' Flex FC should not be used in glazingapplications subject to UV light radiation or directsunlight exposure without prior consultation withBostik.• Seal 'N' Flex FC should not be applied or finishedwith wet tooling techniques, using solvents, water ordetergent/ soap solutions.• Seal 'N' Flex FC sealant should not be applied tounpredictable absorptive surfaces such as marble,limestone or granite unless a standard ofappearance has been agreed on as a result oftesting for stain and/or discolouration.• Seal ‘N’ Flex should not be applied onto or near anybitumen products.• Do not use in interior or exterior structural sealingbelow the waterline in marine applications.• Do not apply at temperatures below 5 o C.• Do not apply to surfaces with special protective orcosmetic coating such as mirrors, reflective glass orsurfaces coated with Teflon, polyurethane orpolypropylene. Will not adhere to polyethylene,polypropylene or PTFE.• For wider joints, Bostik recommends Seal ‘N’ FlexTrafficable (2 components polyurethane sealant).• Seal ‘N’ Flex FC White may yellow or discolour ifexposed to UV light for prolonged periods of time.PAINTABILITYBostik Seal 'N' Flex FC can be painted as early as 24hours after application using water borne coating andmost epoxy coating systems. Coatings containing highsolvent contents such as gloss enamels or high oil basedundercoats may cause the surface of the sealant to reactcreating a tacky surface to develop.A field test is recommended to ensure compatibility. Toobtain best appearance and performance the paint mustapproximate the elongation capabilities of the sealant.High build coatings with some elastomeric ability such asquality acrylic emulsions have the capability to absorb lowmovement without significant distortion of the paint film.Please contact Bostik Technical Department if unsure ofany paint system.HEALTH AND SAFETY• On contact, uncured sealant causes irritation.Gloves and protective goggles must be worn duringapplication and use.• Avoid contact with skin, eyes and avoid breathing invapour.• Wear protective gloves when mixing or using.• If poisoning occurs, contact a doctor.• If swallowed, do not induce vomiting.
