Builders (Renderers) Clay

Blue Circle® Builders (Renderer’s) Clay is a finely milled, air separated Fire Clay. It is also referred to as a Kaolinic Clay as it contains high plasticity, dry strength and refractory properties.

It is mainly used as a plasticiser for mortar and render mixes when the sand that is being used has a low clay content. It improves the workability of mortars and renders.
