In the renovation and restoration of the Philips Tower, a reinforced concrete building in the center of Brussels, the structures were protected from fire for 60 minutes with PROTHERM LIGHT®, a sprayed lightweight cementitious plaster. The required thickness of only 13/32 in (10 mm) in a single coat meant using about 297,624 lb (135,000 kg) of material, against an estimated 892,871 lb (405,000 kg) for a traditional 13/16 in (20 mm), two-coat solution. Unaffected by moisture, the product stayed exposed for about a year before the façade was installed, and also gives a white finish with a very good appearance.
