Answer 2

In a moist area you will always get algae. To remove the algae use a pressure washer. This is an environmentally friendly way to clean all kinds of surfaces. But whatever you use chemicals or water pressure the algae will come back.

Answer 3

Green algae is a plant like growth that grows in moist locations. It arrives by wind-borne spores. The only way to prevent it is to keep the paving slabs dry. It can be killed with products containing zinc or copper. They are sold as moss-b-gone and similar names.

Answer 4

It's just a natural phenomenon! The best way to remove it is to either pressure wash it yourself, or get someone round to do it - I used a company called Revive-a-Drive, who i think are national, and they did a fantastic job. You can use patio cleaning solution which you'll get from any DIY store, but it's hard going and the results are patchy. You can't stop it coming back, because even if you used a fungicide or weedkiller, the rain would keep washing it off.

Answer 5

Jetwasher will get rid of the stuff. It grows because the slabs are wet a lot of the time (part of life in England). Best to just clean it off once a year.

Answer 6

Equal parts bleach and water in a water can and saturate when dry or not raining and let dry

Shady areas promote algae
Careful with surrounding plants it will harm them wash thoroughly

Answer 7

Clorox or Muriatic acid (use precautions). Prevention may be tough due to the moss is under great conditions or it wouldn't grow there. Spray it once a week for control or use straight white vinegar for less toxicity

Answer 8

Soda mixed with water should do the trick, leave it on for
a couple of minutes then brush and rinse off. Algae
thrives in damp or wet places in which case you have
no alternative but to do this whenever it starts to grow.
In the Royal Navy. we clean the wooden decks with soda
and I am sure it will work on other surfaces as well.

Answer 9

nicely a expert concrete/cement guy the patio could be flat (commencing up as deep sufficient so no leaning = puddling) the stairs could have a comfortable downward grade so as which you could not tell yet water runs off/down, not extra that 3%. attempt A Chalk (such as you utilize in bathing room/tubs.) for grout. Water info sealer like thompsons will help besides the undeniable fact that it too degrades over the years

Answer 10

bleach and maybe a scrub brush. Keeping it dry will prevent the yucky stuff from growing

Answer 11

Use a pressure washer. green algae will always come back but don't use chemicals on it...... think of the planet !
