Had KLH spray render the rear of my 1880's mid terrace, removing some damaged and failing pebbledash beforehand. Arctic white. Scott and his partner were quick and efficient, clean and considerate throughout. A lot of time on the prep work, which was good, to ensure a sound base. CorkSol seems a great way to render and, for traditional build, add a layer of insulation that is natural and breathable. Well worth looking at.
