Insurance companies and local authorities are pressing to outlaw flame and molten bitumen on health and safety grounds. Alternatives to traditional flat roofing are becoming essential. One such alternative is Sealoflex. Sealoflex has been used on the London Underground, Westminster Cathedral, The Tate Britain, Gatwick and Heathrow Airports as well as domestic and industrial roofs across the UK.
Repair, renewal or new-build – the Sealoflex range of cold–applied liquid waterproofing systems provide a reliable solution for waterproofing roofs, balconies, walkways and terraces.
Sealoflex is a reinforced liquid waterproofing system that can be applied directly to most surfaces without heat. It ‘cures’ rapidly to form a solid, long lasting flexible waterproof membrane. Sealoflex has two versions – the water based acrylic, which is non toxic and environmentally friendly, and the cold temperature ‘CT’ version which is solvent based and can be laid at -5°C making it ideal for winter applications.
Both combine a flexible emulsion saturant, polyester fabric and a UV resistant flexible topcoat available in numerous colours. The system forms a tough, flexible waterproofing membrane, which, if maintained correctly, has a life expectancy of 25 years.
Both Sealoflex CT and Acrylic offer:
• Long life expectancy
• Ease of maintenance and repair
• No risk of joint failure
• Compatibility to most substrates
• Cost effective waterproofing
• Minimum disruption during installation
• Aesthetic design possibilities
• Generally low risk application
• The capacity to waterproof complex details
• Minimal increase in load
• Resistance to foot trafficking
• Proven performance supported by guarantees.
Sealoflex can be used:
• As flat roof waterproofing.
• To waterproof metal gutters and other box gutters.
• For flashings of all types.
• As parapet wall waterproofing
• For sealing of joints, laps and roofing screws on corrugated metal roofs.
• To encapsulate metal and asbestos roofs.
• Over most existing built up systems.
• For waterproofing balconies, stairs, decks and underground structures.
Application Guidelines
The application is straightforward. Sealoflex systems are cold applied using brush, airless spray or roller. Surfaces should be free of all loose and flaking particles, grease & oil. Priming is only necessary on unprotected iron, steel, older painted surfaces and masonry.
Apply a generous “foundation coat” of Sealoflex Pink. Embed Sealoflex Fabric directly into the coating while still wet. Overlap of adjacent runs of fabric by approx. 10 cm. Ensure that no bubbles or wrinkles occur, and follow with a “saturation coat”
of Sealoflex Pink so that the fabric is completely saturated from above, and allow it to dry. Finally apply a generous coat of Sealoflex Finish.
Coverage:
Sealobond Primer (if necessary) 5M2 / 1 Ltr
Sealoflex “Pink” (total for “foundation” and “saturation” layers/coatings) 0.75 – 1M2 / 1Ltr
Sealoflex “Topcoat” finishing coating 2M2 / 1Ltr
Coverage depends upon the surface you are adhearing to.
The Sealoflex team has trained over 300 contractors this year and will continue with this program into 2007. Training is free and is held at different venues throughout the country. |
