developed to provide water&oil repellency for all types of
stone materials, such as marble, granite, sandstone,
limstone etc.
The active ingredients which is nano-size penetrate deeply
into the substrates and bond with them, form penetration
protective layer on the surface. With super low surface
tension, it boosts excellent water repellency and fast
beading action.
