It can also be used independently as a render of up to 3 mm thick to face up brickwork and other types of masonry. The addition of polymers gives Estopatch FC an extremely durable finish which will not desiccate.

Oil and grease deposits should be removed by steam cleaning, detergent scrubbing or the use of a proprietary degreaser. Any remaining dust or loose material should be blown clean with oil free compressed air.
