    Hello all
    I’m hoping to paint outside of my house this year and I’m looking for some help please. The garden walls are dirty enough in places with blackish streaks running down, The house itself is not too bad, it just looks dull with streaks at one side due to faulty gutters whic I ha/ve to repair. Any ideas of what I might use to spray it with before powerwashing would be greatly appreciated.
    Thanks in advance

    If you can get to angood Agri supply store and get a 20l drum of hypochlorite. It’s a steralising solution.

    Dilute 70% water and spray on the walls, leave for 24hours before washing.

    The 20l drum should cost about €20-25

    Nice one.
    Works on concrete paths too.

    Not nice in the eyes, it’s essentially bulk buy Milton.
