Red mold on outside wall?

    The boundary wall of our site has become covered with an ugly looking red mold. (The wall is pebble dashed).

    I have power hosed about half of it (I'll do the rest tomorrow), which has removed some of the mold, but not all (even though I think I was fairly careful when power washing and got as much as I could off). Is there anything that I can do to get rid of the rest? Any spray that will kill/remove the mold? I'd really like to brighten up the wall, as it looks terrible at the moment.

    Thanks in advance for any advice.

    Bleach and a scrubbing brush.

    Hydrogen peroxide and a scrubbing brush

    Or Mosgo or any of the other propriety moss killers that are on the market.

    Look in any of the garden centres, B&Q, Woodies etc or even better some of the agri hardware places.

    DairyGold make a product called Chloras. It is a chlorine based solution, cost about €15 for 10 liters. farmers use it for sterilising their milking equipment.

    Spray it on neat with with a pressure sprayer. The stains will be gone off the wall within 1 hour. Maybe give it a light washing down with a power house afterwards. No scrubbing.

    All farmer supply shops sell this product (it has various names and manufacturers). Works brilliantly for cleaning the green scum of paths too.
