BMI UK
& Ireland – the largest manufacturer of flat and pitched roofing and
waterproofing solutions in the UK and Europe – has revised and enhanced its
portfolio of market-leading 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 extremely
versatile, single-component system. Being low odour and solvent and VOC-free,
Ultima is 100% hazardless and a superb choice 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, again
important when tenants cannot be decanted and also improving productivity and
profitability.
Suitable for use on
a variety of substrates – from concrete, bitumen and asphalt to plywood/ OSB,
synthetic membranes and even metal roofs – Sealoflex Ultima 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 happily installed adjacent to other flat roofing technologies
Another significant
benefit is that it can be readily over-coated: handy 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, and a
colour choice of grey and 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 ideal for projects where speed of installation is important.
The two-part
catalysed coating also offers low-temperature curing which means it is ideal
for year-round application, and installation in the less climatically
hospitable areas of the UK. This is supported by the provision of a winter
grade coating for use in exposed and aggressive environments, such as coastal,
elevated or northerly situations.
The waterproof
coating – whether summer or winter grade – is RAL ‘Blue Grey’; and can be
augmented with finishes in dark ‘Traffic Grey’, a greener ‘Stone Grey’; or
large quartz (up to 1.2mm) where high skid-resistance is required. Endura is
appropriate for asphalt, bitumen, concrete and metal substrates.
Completing the BMI
Sealoflex collection is Prima: a 2K (two-part primer, two-part waterproofing
coating) system applied as
a complete roof overlay solution or as part of a new warm roof build up. As with Sealoflex Ultima, Prima is also solvent
and VOC-free, making it especially suitable where there may be environmental
concerns around the impact of odour and vapour on contractors, building
occupants or the public at large.
Primers are provided
for concrete, timber, metal, PVC, TPO and bitumen and asphalt substrates. Three
grades of reinforcing fleece are available; and finishes comprise clear liquid
encapsulation, walkway compound or bulking sand and quartz.
BMI UK & Ireland’s dedicated field
service has a network of technical advisers available to provide liquid applied waterproofing specifications that qualify for insurance-backed
guarantees of up to 25 years depending on the system.
The company’s advisory service for specifiers
and contractors is free of charge and consultants are available any time
during business hours to answer queries on cold-applied liquid
waterproofing design and installation.
