Sika Pro-Tecta metal roof solutions unveiled

Regeneration Tue, Jul 30, 2019 4:13 PM

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.”
