Title: algae
Post by: Ged on June 22, 2007, 06:55:57 pm

Hi All
 
can anyone recommend  a good algae killer that will persist. yesterday during a lull in the incessant rain i managed to complete a pressure wash clean of very mossy block paved patio under overhanging trees . the client said it would be green again in a few weeks so i said i'd ask around for him. he is on about having it sealed but i think the moss and algae will still come back. i know its more work for us but this guy has a point it's a really shady damp location.
 
Regards Ged

sealing is the way i would go as then a hosepipe and brush moves any buildup but if you dont want to seal it then apply algon , it has to be applied on a dry day but you should get 9 to twelve months trouble free

forgot to mention if you do seal it then it is worth adding the anti slip granules to the seal otherwise the sealed areas can become really slippy if the algae is left to build up.

I can recommend Algon too. Great stuff and takes the back ache out of it.

I would be tempted to make up a few spray bottles of diluted bleach at different concentrations,  go and spray a few test areas and wait to see which one works and for how long.  Once you have perfected it you can start offering this "moss prevention" as an added extra :D
