Any nurse knows that you can’t just stick a plaster on a serious wound and expect all to be well; some cleaning up and repair work at the very least will be required! The situation is similar with buildings; you cannot repair a building structure simply by giving it a new coat of paint!
The nurses’ accommodation at Grantchester House, a high rise ‘70s block of flats situated in the grounds of Addenbrooke’s hospital in Cambridge, required restoring to good health. The windows needed replacing and the facades needed to be restored. RonaBond HB40 concrete repair mortar was used for the initial concrete repair and the finished facades were then coated with Ronacrete’s RonaBond Zolpacryl to complete the ‘operation’.
RonaBond HB40 is a pre-packed high build, medium strength repair mortar for repairing concrete and protecting reinforcing steel. It is used to repair concrete facades and is suited to overhead application, where its combination of ease of application and strength makes it an ideal product. It can be applied in thick-section layers up to 75mm on walls and soffits.
RonaBond Zolpacryl is a smooth, coloured, water borne acrylic anti-carbonation coating for use on vertical surfaces, soffits and at DPC level. It allows the passage of moisture vapour so it is particularly suited for application to substrates which may contain entrapped moisture. It can be applied to external walls and facades and protects against water, frost, and weathering it is also an effective barrier against the damaging effects of carbon dioxide gas.
RonaBond Zolpacryl is available in a standard range of more than 300 colours, BS or RAL colours can be produced. Life expectancy is in excess of ten years.
