Rombio Mineral Harden, 2.5-liter (Gallon)

For mineral paints such as limewash, Mineral Hardener Concentrate can help block further deterioration from the elements, consolidating your limewash finish, antiqued/decorative or full coverage applications, increasing adherence onto your masonry substrate, such as brick, as well as provide water resistance. Applied directly onto brick can help protect against spalding, particularly on low-fired brick, consolidating the brick surface and providing water resistance simultaneously. Mineral Hardener Concentrate is a blend that contains inorganic compound (K2SiO3), that is water soluble and has been used for a 1000 years as a mineral substrate consolidator. It is historically known as water glass or liquid glass. When applied to an unpainted mineral surface it forms a chemical reaction with the substrate essentially reinforcing and strengthening the inherent mineral aspects of brick, stone and most cements. Mineral Hardener Concentrate strengthens mineral substrates, making them stronger and at the same time, more water resistant Mineral Hardener Concentrate is a zero odor, water based formula, permitting deep penetration into porous surfaces. BioDomus Mineral Hardener concentrate is category BIO which means Organic, containing at least 90% natural raw materials and the other 10% inert binders and non-toxic chemicals.
