ALGAE STAINING ON BRICKWORK
​SYMPTONS, PREVENTION, CURE.

---

Surrounding algae and organic growth can stain brickwork, leaving a mouldy green stain of varying degrees.  

​It is obvious to identify, typically harmless and can be cleaned as required/desired.

CURE.

---

Due to the inherent absorption abilities of brickwork sustained algae and organic growth can be difficult to remove with simple jet wash cleaning. 

​If this is the case use a soft brick acid that will remove all types of algae from ageing brickwork and restore to its original colour finishes.
