cleaning pavers

reno queen · May 29, 2007 12:51 pm

Hi. I have a courtyard that has been paved with clay pavers. I have managed to keep the weeds out but they are covered in what i think is some sort of black algae. It is driving me nuts trying to keep them clean. Does anyone know of a product i could apply to the pavers to stop this from happening or at least slow it down. Any advice is much appreciated. thanks

Time to get the gernie out. Best to blast it off, and then enquire about a treatment to prevent it coming back. i would also look at the drainage and the slope of the paving to check for pooling water.

Hi there,

This company will most certainly have the solution for you...

Powerclean Industries Australia (07) 5474 2785 Speak with Jim Bethel and tell him Ash sent you.

Jim can put you in touch with a local professional service that can pressure clean (and recover the waste) so it is effectively cleaned without a big mess. He can also advise what may be used to prevent further contamination.

Naturally, a professional service will cost more than a DIY approach, but it will give you the best results and be money well spent.

Ash.

I have put my feelers out, and had a response from someone in the Southern suburbs if Brissie. Other areas, and he can advise who's the best. PM me if you like, and I can put you in touch.

Ash.

You might try a herbicide like glyco phosphate.

in all my years of nursery work the only product that has ever managed to rid algae and moss is chlorine. we have tryed every product under the sun and it either comes back fast or just doesn't cut the mustard.

The chorine stops the algae from coming back for upto 12 months but can bleach concrete pavers.
