Protective coating renewed

A roughly 1,400 m2 metal roof covers the Hepco & Becker industrial plant, where a range of motorcycle equipment is manufactured. However, the trapezoidal sheet covering showed signs of damage: after recent hailstorms, the powder coating had ceased to provide adequate protection against weather conditions, such as rain, frost and snow. The coating was flaking off and the surface was badly corroded.

In order to prevent further corrosion, the formation of holes in the roof structure and the penetration of moisture to the production facilities below, it was clear that the roof needed to be refurbished. The task was to apply a long-lasting coating to the roof surface and acute-angled gables, and provide protection against corrosion.

The contractor Gebrüder Folz GmbH has been successfully using Triflex liquid applied waterproofing for a wide variety of applications for five years now. In consultation with Triflex technical advisers, the roofing company also planned to repair the industrial plant's profiled metal sheets using the manufacturer's systems specially developed for metal roofs. The single-component primer Triflex Metal Primer with a high-grade alkyd resin base is used on metal substrates. Quick application is ensured as abrasion is normally not necessary and the material dries quickly. Triflex Metal Coat is applied as a second functional coating. The aqueous product is impact- and shock-resistant, protects against weathering and corrosion, and thus extends the service life of metal structures. The optimum adhesion prevents subsurface water penetration and avoids the formation of rust, while the elasticity of the resin ensures that no cracks or scaling can occur. Triflex Metal Coat and Triflex Metal Primer can be applied by spraying or rolling on.

Prior to coating the trapezoidal sheet metal, the Folz roofing team cleaned the entire surface using high-pressure cleaners. Triflex Metal Primer was then applied. After priming, the detail waterproofing system Triflex ProDetail was used in the transition areas in particular. The contractors then applied two layers of the corrosion protection coating Triflex Metal Coat crosswise. Use of the airless-spray method ensured quick and easy application of the new surface coating.
