Long Rake Spar, suppliers of decorative aggregate, has launched a new coloured natural dashing aggregate, free from iron sulphide, the usual cause of long-term discolouration on rendered walls

Honey Yellow marble, a pale golden yellow coloured dashing aggregate, is suitable for the exterior rendering of residential and local authority construction projects. Until recently, most yellow or golden coloured dashing aggregates were sourced from gravel deposits, which could contain iron sulphide that oxidises with weathering. This results in rust staining and brown discolouration to the render. The new Honey Yellow product is totally iron-free, claims the company.
