Cementitious Paint
Cementitious fire protection is normally spray applied using specialist equipment to protect structural steel or concrete from the effects of fire for a nominal fire resistance period.
Gypsum based sprays are sometimes considered as Cementitious and may be used internally in the same way as Portland cement sprays, though most gypsums are not suitable for external or semi-external locations.
The gypsum based fireproofing Cementitious paint has excellent physical properties for interior/architectural uses and Cementitious paint can give up to 4 hours fire protection.
