    I'm a bit new round here but this looks like a really good forum so I'm hoping to get some advice on the following problem. At the bottom of our garden is quite a high brick wall the bottom half of which looks particularly untidy: its old, some of the mortar is lost from joints, and was obviously a quick job in the first place as the mortar finish is really bad.

    So I want to tidy it up by covering a section up to about shoulder height in white render furthermore into part of this my girlfriend wants to make a pattern with bits of broken crockery. I've not really done anything like this before so I'm looking for a bit of guidance. I'm thinking that I need to put a concrete render on first to get everything flat and also to fill in the areas of missing mortar. Following this I'm thinking of a second coat of snowcrete and white sand (so that the finish is white), before this goes off we'll push the bits of crockery into it. Is this likely to work or am I miles off the mark?

    Thanks!

    This will work.

    Get washed , salt free, fine sharp, (3mm down) white sand.

    You can check if it is indeed salt free (if you don't like tasting it!) by putting some in a cup of water, stirring it, pouring the water on a saucer and letting it evaporate. You'll see rings of salt left if it has not been washed properly.

    IF you put water proofer in the 4:1 scratch coat, then you'll stop salts and oxides coming in through from the blockwork.

    a 5:1:1: White Sand:Snowcrete: Lime mix for the top coat will give you a nice colour but guage this out with buckets to give you uniform shade.

    The crockery wants to be washed and dried so that there is no dust on it.

    Especially f it is glazed, it needs to get a little twist as you bed it in so that it it gripped by the render rather than just relying on the render sticking to it.

    Be aware of sharp edges. Also consider filling any concave bits before you put them on , so that they are not hollow and hold water in behind - or are easy to break by getting a smack of ,say, a football or kids just trying to smash them.

    Pic when finished please!
