Conservare OH100 is a ready-to-use consolidation treatment that stabilizes masonry by replacing the natural binding materials lost due to weathering, with silicon dioxide. When properly applied, Conservare OH100 penetrates deeply, does not form a dense surface crust, and retains the substrate's natural vapor permeability. In addition to the general consolidation of severely deteriorated masonries, Conservare OH100 is an effective pre-treatment for friable substrates that need to be strengthened before cleaning, patching or coating. Conservare OH100 may be used on most types of natural stone, concrete, stucco, brick, terra cotta, etc. One component and easy to use, OH100 strengthens deteriorated stone and features a low viscosity to allow for deep penetration. Will not form hardened surface crust. The new binder is mineral -- similar to the original stone -- no synthetic polymers.
