have just bought an old property with wall tie corrosion in rear elevations. the company who have quoted for the work want to pebbledash the whole rear wall once the wall ties have been repaired. The main part of the house is constructed of engineering bricks the rear part isnt, and will need protection, i would like some ideas about how to avoid grazed elbows and small stones all over the patio but still protect these more vulnerable bricks. aesthetically i like the bricks and would love some sort of clear matt (undetectable) finish.......i dont know what is out there however, any ideas?
