Formerly known as Louis la Grange Square, the Mount Road Police Station in Port Elizabeth was originally constructed in 1925. By 2010, the ageing façade of the building was in dire need of a facelift. Atlantic Aluminium were contracted to install HulaBond panels in order to lend the building a modern, aesthetically appealing appearance. It was specified that this project should be cost-effective, thus two of Sika’s long-lasting, highly resistant products were chosen to bond and seal all the aluminium panels.

Sika Cleaner-205 was used to clean the HulaBond panels and channels. This cleaner is a solvent-based adhesion promoter designed for the activation of surfaces prior to bonding and sealing with products from the Sikaflex range. Sika Cleaner-205 can be used to activate various non-porous substrates such as metals, plastics, ceramics and painted surfaces, and its application temperature ranges from 5 to 40oC.

For bonding the HulaBond cladding to the aluminium channels and for sealing between the HulaBond panels, Sikaflex-221 (8000 x 600ml, light grey) was applied. This high quality, multi-purpose, non-sag, 1-C polyurethane sealant cures on exposure to atmospheric humidity to form a durable elastomer. It has low odour, is non-corrosive, can be sanded and over-painted, and bonds well to a wide variety of substrates. It is resistant to fresh water, seawater, limewater, sewage effluent, diluted acids and caustic solutions. Sika Cleaner-205 and Sikaflex-221 are both manufactured by Sika in accordance with ISO 9001/14001 quality assurance system.

To assist applicators with the installation of the aluminium panels, scaffolding to a height of 30metres was erected around the entire building. For safety reasons, work was suspended when the notorious Port Elizabeth winds blew and was only resumed once the wind speeds decreased to less than ten knots.

Despite the weather delays, this Sika project was completed in December 2011, within the 15-month time frame. The city of Port Elizabeth and its police force can feel proud of the new-look Mount Road Police Station.
