The multi-award winning Library of Birmingham, the biggest public building of its kind in Europe, was treated with FILA protection and care systems. Thanks to CLEANER PRO (pH neutral detergent) and W68 (eco-friendly stain protector) over 1,800 m² of slate installed throughout the ground floor of the library and adjacent theatre were cleaned and protected. A project costing 189 million pounds (over 23 million euros) which has already had one and half million visitors since its inauguration in September 2013. The Brazilian slate slabs were laid by W.B. Simpson & Sons in the Midlands. After installation, CLEANER PRO concentrated neutral detergent was used for cleaning, specific for delicate natural stone like slate. The surface was then treated with W68, a water-based, eco-friendly stain protector ideal for porous surfaces, which does not form any surface film and protects the material without altering its natural appearance.
