Advises on cleaning, surface repair and maintenance of masonry constructed of natural stone, cast stone (artificial stone) and/or clay or calcium silicate bricks. Where work on features of artistic or historic importance is being undertaken guidance from specialists should be obtained since general recommendations may need to be supplemented. Structural repairs are excluded.
