    Default Rendering and waterproofing house wall - preparing the brick wall

    Our front yard slopes down towards our garage wall and is covered by about a metre. We have dug it out and will waterproof the wall and create drainage. Our waterproofing will involve applying an acrylic render, then using a waterproof paint, then apply a layer of corflute to the wall. Will then have 100mm agpipe at the bottom and then filled with gravel.

    Weíve dug it out and are ready to apply the acrylic render. The wall has dried and appears to be covered in an old waterproofing (several mm thick cement/render with a green or black hue, but is thinner and lighter than the actual render which higher up the wall above the level of the ground) which breaks down into fine dust when I use a stiff yard broom to clean and prepare the surface.

    What is the old surface? Can I render directly onto it or do I need to remove it back to bare bricks? Iíve not use this forum before, is there anyway to share pictures?
