Limestone masonry veneer, resurfacing and aesthetic overlay compositions, methods of making and methods of use

A masonry veneer coating composition comprising:

• a natural hydraulic lime of NHL grade 3.5;
• and
• a natural limestone being finely divided with a mesh that is a number 6 mesh, a number 40 mesh or a mesh of a size there between;
• and
• a reactant selected from the group consisting of a calcium silicate hydrate forming material and a pozzolan;
• and
• a bonding agent selected from the group consisting of polyvinyl acetate and polyvinyl alcohols, wherein the bonding agent is in an amount up to about 5 wt. % based on a dry weight;
• and
• water in an amount to form a slurry having solids content when wet of between about 60 wt. % and about 90 wt. %;
• and
• the natural hydraulic lime comprising not more than 18 wt. % based on the dry weight,
• the coating composition being capable of stiffening in about 1 hour, such that the stiffened surface of the coating composition allows application of a decorative tool or carving tool to the stiffened surface within about 1 hour after depositing the coating composition at a thickness of between about 0.5 inches and about 1.5 inches,
• the coating composition taking up to about 24 hours to fully set, and
• the coating composition when fully formed having a calcium carbonate limestone content of at least 92%.

A dry masonry veneer formulation comprising:

• a hydraulic binder, which includes at least a natural hydraulic lime of NHL grade 3.5, the hydraulic binder in an amount between about 3 wt. % and about 16 wt. % based on a dry weight of the formulation;
• and
• an aggregate comprising natural limestone, the aggregate being initially screened with a mesh that is a number 6 mesh, a number 40 mesh or a mesh of a size there between, wherein the aggregate is in an amount between about 70 wt. % and about 90 wt. % based on the dry weight of the formulation;
• and
• a pozzolan reactant, wherein the reactant is in an amount so that the ratio of reactant to natural hydraulic lime is between 1:2.5 to 2.5:1;
• and
• a bonding agent selected from the group consisting of polyvinyl acetate and polyvinyl alcohols, wherein the bonding agent is in the amount up to about 5% of the weight of the dry formulation;
• calcium stearate in an amount that is between about 0.1% to about 5% of the weight of the dry formulation;
• and
• water in an amount to form a slurry having solids content when wet of between about 60 wt. % and about 90 wt. %.
