Bristol Roc is an exterior coating which is waterbased and can be applied by brush, roller or spray gun. The finished surface dries to a  tough fine mica texture which is ideal for application to most masonary surfaces as well as being an excellent finish for polystyrene sculptured objects. 

Bristol Roc was chosen for its finish and used exclusively on a full size replica of Stonehenge which produced by Crawley Creatures for a Channel 5 documentary in July 2005.
