BMI UK & Ireland has revised and enhanced its portfolio of flat roofing technologies with the introduction of BMI Sealoflex. BMI Sealoflex is a liquid-applied waterproofing range which offers building owners, designers and contractors a great choice of high-performance system solutions for a host of requirements and applications.
To provide ultimate specification and installation peace of mind, the three systems in the range – Sealoflex Ultima, Sealoflex Prima and Sealoflex Endura – are all backed by the company’s market-leading guarantees and six-step specification service to meet customer design and technical needs.
Headlining the new collection is Sealoflex Ultima, a lightweight, seamless and versatile, single-component system. Being low odour and solvent and VOC-free, Ultima is 100% hazardless for use in refurbishment applications where there may be environmental sensitivities – such as concerns over emission impacts on installation teams or building occupants who need to remain in situ.
Its single component chemistry, ‘wet-on-wet’ application and fast cure time of, depending on environmental conditions, 45 minutes to ‘rainproof’ and two hours to overcoating means installers can get on and off the roof quickly.
Sealoflex Ultima is suitable for use on a variety of substrates – from concrete, bitumen and asphalt to plywood/ OSB, synthetic membranes and even metal roofs – and can be deployed in new builds as well as providing a complete overlay solution on existing roofs. Its flexibility lends itself to complex geometries, penetrations and detailing, while it can be installed adjacent to other flat roofing technologies.
Another significant benefit is that it can be readily over-coated for repairs, renewal and when coating thicknesses were insufficient during initial application.
The waterproof coating comes in four and 15-litre resealable cans to reduce waste, with a colour choice of grey or white. Two reinforcing fabrics are offered, depending on traffic requirements, and the system is supported by a complete range of primers for all possible substrates and a choice of either a liquid UV-resistant ‘wear coat’ or anti-skid quartz granules for walkways as finishes.
For high-traffic areas where membranes need to be exceptionally hard-wearing, such as balconies, walkways, roof terraces and podium decks, the Sealoflex Endura system combines superior membrane durability with fast application and rapid curing times. Where extra resistance to wear and traffic is required, polymethyl methacrylate (PMMA) filling fibres can be added to the coating to make it super tough. With a fast curing time of around 30 minutes, it is also suitable for projects where speed of installation is important.
