Basic rendering began as a method of excluding draughts and rain by using clay to fill in cracks and crevices, referred to as wattle-and-daub.
The introduction of Portland cement[3] meant that durable mortars[4] could be produced and weather resistant renders resulted.
Through the years technological advances have aided the development of cutting edge render systems that aim to improve the longevity of a buildings structural capacity.
All the render ingredients are dry blended together in a modern factory, creating a powdered product which can be supplied in bags.
[8] Supplying a render in this way allows the manufacturer to include performance enhancing additives into the formulation.
