The standard way to protect stone is to apply ‘sealers’. However – sealers cannot prevent etching and staining for an extended period of time, or for that matter, fill the imperfections in the stone surface that harbour bacteria. If you look closely at a natural stone’s surface it is full of open fissures, cavities, cracks, and faults that look, from a distance, like dull areas on the surface, or a different coloured vein that is a softer material than the main stone. These imperfections add to the stone’s aesthetic appearance and can be the reason for choosing the stone in the first place. Sheerstone creates an ultra-sheer, protective barrier over the entire surface – like a layer of liquid glass, filling the imperfections and leaving a smooth surface that protects and enhances the beauty of natural stone. Chemicals/materials cannot come into contact with the stone – and bacteria has nowhere to grow.
