Sika Liquid Plastics, the specialist in liquid roofing and
waterproofing systems, has launched the Sika Pro-Tecta range of systems; a
complete solution for metal roof refurbishment.
The new range includes both a cut-edge corrosion treatment option
and a full roof sheet encapsulation system, backed by guarantees.
The cut-edge corrosion system, Sika Pro-Tecta CE, combines a
newly-developed primer and top coat, which have been specifically formulated as
a system by Sika’s globally-recognised Industrial Coatings Division.
Meanwhile, the full waterproofing system, Sika Pro-Tecta WP,
incorporates an easy-to-use, self-adhesive tape which dramatically reduces the
installation time associated with reinforcement of metal roof sheets, prior to
the main coating application.
The launch of the new Sika Pro-Tecta range builds on the extensive
track record of Sika Liquid Plastics in supplying full waterproofing solutions
for metal roofs, with the acclaimed Sikalastic-625 and Decothane Ultra
coatings. Previous projects have included high profile clients and sites, such
as an operational refurbishment of Pinewood Studios’ Cardiff location and the
Mercedes Car Dealership in Newcastle.
Gavin White, Sika Liquid Plastics’ product manager for Liquid
Applied Membranes explains: “The ease and speed of metal roof construction
means that metal roofs are a popular choice for large, new industrial-type
buildings, across a range of sectors, including manufacturing, retail and
leisure, to name a few. Factors, such as geographical location, the type of
sheet used and the type of coating applied at the point of manufacture, all
influence a metal roof’s lifespan. Very often, some maintenance will be
required after a period of time to prevent degradation of the sheet coating,
and if left untreated, the integrity of the roof system, and potentially
operations within the building could eventually become compromised.
“As a market leader in liquid applied roof membranes, Sika Liquid
Plastics has developed the Sika Pro-Tecta range to provide a choice of two
solutions, depending on the condition and design of the roof, to extend its
service life.”
Sika Liquid Plastics’ Sika Pro-Tecta CE system has been developed
to offer a cost-effective solution for targeted treatment of cut edge
corrosion, where the ‘cut edge’ of the metal sheet has been exposed to the
elements and weathering over time, causing the sheet coating to peel away and
expose the metal sheet core to further corrosion. If cut edge corrosion is
fully addressed at an early stage, where the sheet is still structurally sound
and not leaking, the service life of the sheet can be extended.
The Sika Pro-Tecta CE system comprises a high-performance primer,
Sika Poxicolor HE New, which has been specifically-formulated for application
in a single coat to manually prepared surfaces. This is then followed by two
coats of SikaCor EG-5; an acrylic polyurethane hybrid. The Sika Pro-Tecta CE
system provides an unrestricted and hard-wearing solution across the UK
mainland, including Industrial and coastal areas with moderate salinity, and is
backed by a product guarantee.
For metal roof sheets that are at an advanced stage of
degradation, including loss of primary waterproofing function, Sika Liquid
Plastics has developed the Sika Pro-Tecta WP system, which incorporates Sika
Joint Tape SA as part of a solution, which is faster and easier to install than
many conventional metal roof refurbishment solutions.
The innovative, self-adhesive Sika Joint Tape SA is available in
two widths: a 150mm tape, for the reinforcement of the end laps, side laps and
their associated fixings, and a 75mm tape for reinforcement of non-lap and
random fixings. The tape is cut to size on site to meet the requirements of the
roof, and, once all the laps and fixings have been reinforced, the installer
simply applies a light flash coating of liquid membrane to the surface of the
tape, followed by the two main coats at the coverage rate specified. The flash
coat and two main coats will always be done in the main specified cold-applied
coating which can either be the low odour Decothane Ultra system or the
Sikalastic-625 system, depending on project requirements.
The Sika Pro-Tecta WP systems are backed by waterproofing
guarantees and extensive technical and specification support as standard, which
includes condition surveys, on-site inspections and final sign-off.
Gavin continues: “With the Sika Pro-Tecta range, we have developed
a range of refurbishment coatings for metal roofs – from the treatment of
cut edge corrosion, through to full waterproofing systems, and our technical
team will advise on the most appropriate solution for each individual project.
This system continues our customer-focused approach to the roof refurbishment
market, ensuring our systems meet all specification requirements, budgets and
complexities.”
