Used to the instructions on the pack on black algae created by sea gull fouling. The algae appears to have been killed off but to remove it from the building it will need to be pressure washed whereas the product guidance indicated that the algae would disappear after three days. Hoping that the algae has been killed off and does not reappear.

Have used Algae Clean on my K Rendered property and am pleased with the result. The property had a lot of red stains on it but Algae Clean as removed them. It does not appear to work on black stains?

Excellent product! Our house is rendered all round, but the front of house does not get as much direct sun as other aspects. As a result we started to get a green algae appear over autumn. This has gotten rid of it all, I am going to recommend to others on our development as the effects are striking. Be patient if treating first time, it took a few days, but did clear the whole area. My house is white again!!

This is good stuff and does the job excellently. I have used it before and although it has a sell by date it does work even if you go over. Certainly recommend the product, as well as K Rend itself.

I bought this from Builder Depot 2 years ago. I didn't think it would work but thought it worth a try rather than get in a professional company to remove the green from my house walls. It was amazing and did everything it says. I didn't believe the algae would just weather off and not need washing down but it did just as it states. I didn't need to use it last year but have to treat again this spring which is better than expected as it states it will last for one year. If we hadn't had such wet weather I think it could have lasted even longer without further treatment. Highly recommend.
