SUBSTRATE PREPARATIONClean all joints 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 as necessary bygrinding, saw cutting, blast cleaning (sand or water),mechanical abrading or a combination of thesemethods that will be required to provide a sound, cleanand dry surface for sealant application. Dust, looseparticles, etc. should be blown out of joints with oil-free compressed air or vacuum cleaned. Non-porousand plastic surfaces should be cleaned by a solventprocedure or by mechanical means.

PRIMINGConflex LMConflex LMConflex LMConflex LMConflex LM polyurethane weatherproofing sealant mayrequire Conflex LM PrimerConflex LM PrimerConflex LM PrimerConflex LM PrimerConflex LM Primer for masonry, steel and mostcommon building materials. Joints must be thoroughlydry before applying primer and sealant. If sealant is to beapplied to a material with specially treated surfaces or ofparticularly unusual surface characteristic consult CormixInternational for primer recommendations. Prior to anyuse, however, it is always recommended that a bead ofsealant be applied on the surface to test adhesion. Cormixrecommends priming of all joints subjected to immersion.Apply Conflex LMConflex LMConflex LMConflex LMConflex LM PrimerPrimerPrimerPrimerPrimer a min. of 30 minutes and amax. of 6 hours prior to the application of Conflex sealant.Primed areas not sealed within 6 hours should be re-prepared and primed.

DESCRIPTIONConflex LMConflex LMConflex LMConflex LMConflex LM is a one component low modulus polyurethanesealant curing via air humidity to form a highly elasticweather proof seal.

USES & ADVANTAGESConflex LMConflex LMConflex LMConflex LMConflex LM is used for sealing joints where apermanently flexible seal is required e.g. expansion andconstruction joints in precast and insitu concrete, parapets,brick and blockwork, window and door permanentsealing, acoustic jointing, marble, granite and G.R.C.facades, external cladding curtain walls etc.Advantages include:-Advantages include:-Advantages include:-Advantages include:-Advantages include:-• Excellent weathering resistance.• Can be over painted.• Non staining.• 50% total joint movement.• Excellent acoustic rating.• Non toxic, approved for potable water contact.• High Durability.• 1 component ready for use.• No mixing, less wastage.

JOINT DESIGNJOINT DESIGNJOINT DESIGNJOINT DESIGNJOINT DESIGNMore joint movement can be accommodated in a thinbead of sealant than a thick bead.Conflex LMConflex LMConflex LMConflex LMConflex LM polyurethane sealant depth should be aminimum of 6 mm. or half of the joint width, whichever isgreater. Back up materials impregnated with oil orbitumen materials are not to be used. Adhesion betweenthe back up material and sealant must not occur becausethe excessive stresses exerted on the product may causefailure of the sealant.
