Clean exterior Oamaru stone such as walls and sculptures.
Removal of Moss, Mould, Algae and Lichen
Oamaru stone is prone to the growth of algae, mould, moss etc. because its porous surface retains moisture. The stone can be further damaged by frost when the water in the porous stone freezes and cracks the stone surface. It is possible to treat the stone with Kiwicare NO Leaks Masonry Sealer to make it water repellent. This product still allows the stone to 'breathe'.
Advanced formulation to clean everyday problems on most outdoor surfaces.
