The difference is that in renders, the final thickness is 15 mm. [7] Development of a site mixed render is the factory made render. All the render ingredients are dry blended together in a modern factory, creating a powdered product which can be supplied in bags.
Cement render or cement plaster is the application of a mortar mix of sand and cement, (optionally lime) and water to brick, concrete, stone, or mud brick.

The finishing or setting coat is about 3 ⁄ 16 inches thick, and is worked with a hand float on the surface of the rendering, which must first be well wetted.
In Economy Village, the rear and middle wythes of brick dwelling walls are laid in a clay and sand mortar with the front wythe bedded in a lime and sand mortar to provide a weather proof seal to protect from water penetration.

Hydraulic lime plaster is not as hard as cement plaster. Hydraulic limes and historic limes were graded as feeble, moderate and eminent. Modern hydraulic limes would be graded at 2, 3.5, or 5 newtons. Portland cement plaster on the other hand would typically be in the region of 25 to 35 newtons when cured; i.e. up to 10 times harder.
