Cement-based cultured stone color post-repair slurry, preparation and repair construction method thereof

The invention provides cement-based cultured stone color post-repair slurry, a preparation method and a repair construction method thereof. By means of optimization of a cement-based nature cultured stone-imitated color post-repair formula, slurry being suitable for different spray-coating method is prepared, wherein the sequence of color forming is controlled to achieve a reverse thinking mode of product repairing. In addition, by means of spray-coating overlapping of main color slurry and auxiliary color slurry in a wet-to-wet manner, the slurry, after being dried, can form naturally merging so that the repair construction method can recover the original appearance of the product and is strong in operability. During the preparation method of the post-repair slurry, the separating-mixing operation is mainly to satisfy the difference of dispersion requirements of different components. The viscosity of the main color slurry and the auxiliary color slurry are 70-150 KU. The post-repair slurry is scientific in formula, is outstanding in performance and is low in cost. The repair construction method is strong in operability, is natural in transition and is lifelike in repairing. The invention can solve and improve production and engineering repairing and the methods are feasible.
