My render is covering the front, back and side of my end terraced house. The front and back seem to be ok witha few hairline cracks but the side has taken some battering from the weather etc. I am looking for a solution to either repair or replace with a product that will also waterproof my home. I have looked at all kinds of things on line but remain unsure what the best thing would be. Some of the render at the side under the yard wall has fallen off. Im stuck what to do.
