ABSTRACT:
This invention is related to a procedure to produce paste for stone quarry, calcareous stones and other porous stony finishing, similar to cement or mortar, which comprises the combination of resin with calcium carbonate, silica grit or river sand aggregate, to give body to the resin. The aggregate can be mixed with cement and be pigmented in different colors and milled in diverse grain sizes for example, to obtain a perfect copy of stone quarry. It is possible also, to use additives like cobalt and catalysts to protect resin from ultraviolet rays or from flames, in case the binding paste comes in contact with fire.
Additionally, the binding paste comprises quantities of water to produce cavities for porosity. It also contains a silica product named Aerosil, which allows the paste to become more dense to help its laying in the mold, without the necessity to pour as a liquid. If the paste is too dense it can be diluted with monomers.
Detergent is used to ease the laying of the paste in the mold by hand. Fiberglass filament is used to improve the mechanical qualities.
