Smooth, non-slumping paste that is easy to apply. Provides good movement accommodation for various building joints. Suitable for joints within a specified width range; moving joints should be designed to an optimum width-to-depth ratio to minimise stress on the sealant.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eBroad adhesion\u003c\/strong\u003e — bonds to most common building materials\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSingle component, fast cure\u003c\/strong\u003e — no mixing required, rapid cure rate\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eEasy to apply\u003c\/strong\u003e — smooth paste, gun-applied\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eUV resistant\u003c\/strong\u003e — suitable for long-term exterior exposure\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003ePrimerless for most applications\u003c\/strong\u003e — generally no primer needed\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eColour range\u003c\/strong\u003e — available in multiple colours\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eInternational standards compliant\u003c\/strong\u003e — ISO 11600, ASTM C920 and others (per manufacturer)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eConcrete structural joint sealing\u003c\/li\u003e\n\u003cli\u003eBrickwork and blockwork joint sealing\u003c\/li\u003e\n\u003cli\u003ePrecast concrete panel joints\u003c\/li\u003e\n\u003cli\u003eStone cladding joints\u003c\/li\u003e\n\u003cli\u003ePerimeter sealing around doors and windows\u003c\/li\u003e\n\u003cli\u003eNon-trafficked floor joints\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eApplication Guidelines\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eSurface preparation\u003c\/strong\u003e — joint surfaces must be clean, dry and frost-free; remove dirt, laitance, loose material and rust\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003ePriming\u003c\/strong\u003e — generally not required; for high-movement or intermittently immersed joints, use Fosroc Primer 7 (porous) or Primer 4 (non-porous)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eBacker rod\u003c\/strong\u003e — use polyethylene foam backer rod in expansion joints; use bond breaker tape in contraction joints\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e — gun sealant firmly into joint and tool flush shortly after application\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eFinishing\u003c\/strong\u003e — mask joint edges before sealing for neat finish lines\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003ePackaging\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e600 ml sachets (10 per box)\u003c\/li\u003e\n\u003cli\u003e310 ml cartridges (subject to minimum order quantity)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eNotes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDo not apply at low temperatures\u003c\/li\u003e\n\u003cli\u003eNot suitable for water-immersed conditions (use Nitoseal MS600)\u003c\/li\u003e\n\u003cli\u003eNot suitable for contact with bituminous materials\u003c\/li\u003e\n\u003cli\u003eNot suitable for trafficked floor joints (use Nitoseal MS300)\u003c\/li\u003e\n\u003cli\u003eMay stain decorative stone (use Nitoseal MS100 for non-staining)\u003c\/li\u003e\n\u003cli\u003eNot suitable for contact with solvents, oil or petrol\u003c\/li\u003e\n\u003cli\u003eColour change may occur on exterior exposure but does not affect physical properties\u003c\/li\u003e\n\u003cli\u003eShelf life: twelve months in original packaging in cool, dry conditions (per manufacturer)\u003c\/li\u003e\n\u003cli\u003eFor detailed application methods, coverage rates and technical parameters, refer to the official product data sheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003ch3\u003eHow does PU40 differ from the MS sealant series?\u003c\/h3\u003e\n\u003cp\u003ePU40 is a polyurethane (PU) sealant suited for general building joint sealing, primerless for most applications. The MS series are modified silicone sealants with specific strengths: MS600 for water-immersed conditions, MS300 for trafficked floor joints, MS100 for non-staining applications on stone.
