PermaRock Stone Chip Render

PermaRock Stone Chip Render is a ready-mixed, acrylate based exposed aggregate finish with colour coordinated natural stone granules, suitable for use as a finishing render for wall bases and on render / external wall insulation systems.


The solvent-free, water-based formulation is environmentally friendly and achieves a silk-matt, scrub resistant, cleanable, tough and hard wearing decorative finish that is resistant to aggressive air pollutants, moss, algae and fungal growths.

PermaRock Stone Chip Render is available in a standard range of 9 coordinated colour combinations. Other colour combinations can be provided subject to minimum order quantities.

Method of Application

Apply a coat of PermaRock K & R Primer (colour to suit) onto the Base Coat by roller or brush. Once dry, PermaRock Stone Chip Render is applied onto the prepared surface by stainless steel trowel, then rubbed down to the particle size and smoothened out with a plastic float.

After allowing the material to dry slightly on its surface, it is smoothed again with a clean stainless steel trowel.
