    What ho one and all,

    We have a cavity brick wall on the boundary; it was originally the garage wall, with the other side on the boundary. When we demolished the bungalow, we kept the wall and placed bricks on the top to seal the cavity. So the brickwork on the inside of the garage was in good condition.

    However, our house now has a path down that side and what was internal brick, is now external. Many of the upper level bricks are spalling and certainly, the mortar also needs some treatment. It will be expensive and although something I could do, my interest level is not so high.

    I am wondering what is the best solution to generally make the wall have a better appearance. Would covering with an external render board and the a masonry paint be an idea? And also some kind of wider top capping, but what?

    Grateful for any ideas.

    Thanks and toodle pip

    As an alternative to board and paint, could you perhaps just cover the wall with render? Could just be slapped on, I expect, to leave a rough finish?

    For the top there's a wide variety of stone or concrete copings and cappings available.

    That's a good idea. Tyrolean finish? Easy to apply with one of their hand machine which can be hired. Quick too.

    Sand and cement render for me too. Seal, then scratch coat, then top coat. it is possible to get one coat renders, I don't know how good they are for external use though. If you go for simple sand and cement or plastering sand you could also add some fibre reinforcement to the mix especially if the wall is a bit iffy.
    For capping you could try something different like old pantiles for a bit of interest.

    Thanks. Have hot considered just rendering over the whole, principally because I thought that perhaps the base is too loose for good adherence.

    Presumably this is really a summer job when the brickwork is dry?

    The top is a bit more of an issue as I have not found anything that is sufficiently wide to cover a cavity wall and a bit of overhang. Have considered a wide lead sheet that I could wrap over the edge.

    Look for 350 mm wide single or twice weathered coping stones. they should easily cover a cavity wall of 2 X 100 mm block/brick and a 75 cavity, Plenty of ebay at present
  1.  
    Grow ivy or honeysuckle up it, great for wildlife.

    Or replace with a hedge?!!

    I'd have thought that if you go over the surface first with a wire brush or chisel as appropriate to make sure there's no loose bits there then there wouldn't be a problem. Any spalled surface will provide a better key than smooth brick.
