No need

No need to try to save on black materials, since they will depend on how high -quality and durable repair will be in general.

Here is a basic list of black materials that are necessary for repair and finishes: grooves or foam blocks used to arrange internal partitions; a mixture used in alignment of surfaces; a mixture used in the installation of floor screeds (usually it is sandblast or expanded clay); a mixture used for puttying ceilings and wall surfaces; primers (primer liquids); grids for plaster (painting) work; glue for tiles; Lights and reinforcement.
