CONCRETE & STONEWORK
After

OUT DAMN SPOT !

Warmer and longer Spring and Summers periods have seen the British public embrace the great outdoors , generating the Alfresco Dining revolution of the past 12- 15 years , .
Households have invested small fortunes on natural stone Patios and terraces , as the centre piece of their garden ; four - course , candle - lite dinners , complimented by fine wines and stilletos , have replaced the invitation for a “ beer , a burger and a bun ,” on a dirty patio , of the last century !
For the first two years , the area maintains it pristine appearance . At the beginning of the third year , tiny , vivid , black spots begin to appear , on certain slabs , almost by stealth .
After five years , the entire area has become infested , and the Patio has become something of an eyesore !
Pressure washing removes the dirt , but merely accentuates their appearance !
Before
Excess pressure washing vibrates the surface , causing delamination , and breaks down the surface of the stone , Your valuable investment has lost its beauty and value !
THE CAUSE
Patio Black Spots ® are spores of black lichen , the size of pollen , that emanate from the trees . Carried on the breeze , when it rains , they are watered into the pores in your garden stonework ; feeding off the various minerals in the stone , by the beginning of the 3rd Year , the spores have germinated , anchoring themselves into the surface , which is why pressure washing alone , has little effect .
Most “ patio cleaners ” contain pesticides , or , worse , acid , which will dissolve limestone and stain sandstone orange , not to mention , having a devastating effect on surrounding plants .
