Slppy green algae on block paving, removal
Hi all
I was about to jet my patio but the pressure washer broke. Is there another way of ridding this stuff without jetting; and preferably the less labour intensive methods please? -- Regards p.mc |

You could try this, not particularly cheap but it goes a long way. http://www.armillatox.com/default.htm -- Corporal Jones "Don't panic don't panic" Life will go on albeit somewhat reduced |

Is there another way of ridding this stuff without jetting hmm, last year's favourite tool, the angle grinder? :-) I sympathise - doing the patio with a pressure washer was always a right pain in the bum. Thankfully we just don't seem to get algae here - maybe it's a humidity thing. |

Pressure washing stone often leaves it more susceptible to algae in future as it leaves a rough surface that they like. R. |

Pressure washing stone often leaves it more susceptible to algae in future as it leaves a rough surface that they like. R. indeed, a la sandblasting off decades of "grim" soot based northern- ness from countless town halls, church steeples etc - AIUI often leaves a surface that deteriorates *more* quickly than if it was left alone. Something to do with the soot creating "harder" compunds with the top few thou of the stone.... cynically one could also observe that the same firms that recommend and then do the sandblasting are also the "specialist stone masons" that then magically appear at vast expense to repair the damage that their "cleaning" initiated/caused....mmmmm....

I had pressure washed the block paving at the side of the house in the summer, and the first overwinter the algae appeared. -- Regards p.mc |
