The brick wall is treated with solutions based on cement, sometimes with the addition of lime. With a layer of a layer of more than 20 millimeters, you should use a grid for plaster walls to avoid a collapse.
To obtain a solution, a mixture of cement and sand in a ratio of 1: 3-5 is gradually poured with water until the consistency of the dough is achieved. For a limestone solution, 7 parts of sand and 3 parts of lime milk are added to 1 part of the cement.
Proper plaster in the internal walls of facing bricks is very energy -consumed and requires special equipment, so it is better to give this type of decoration to professionals.
Smooth concrete wall is treated with a solution of lime and gypsum in a proportion of 4: 1. Gypsum is poured into the water with a thin layer and knead until a very thick mixture is formed.

The uneven concrete wall does not need to add quartz and can be detachable both from cement and gypsum solution.
Foam concrete walls should be first treated with a primer, and then they can be plastered with gypsum solutions.
