Preparing for plastering
As the video shows the master class, Venetian plaster is applied to the surface, which was previously prepared. The material is placed only on a flat building base. Therefore, before the main work the surface is plastered and sanded. After that, apply two primer layers to the base with a break for drying. Professionals advise using a deep penetration primer with antiseptic properties. Such a coating will protect the surface from mold and mildew.
Cooking Tools
Put the dry mixture in a bucket and fill the product with water. The proportions of the components are indicated on the packaging. Take an industrial mixer or drill with a mixer nozzle and stir the composition. When the material has the consistency of thick sour cream, add color. Then mix the solution again so that the dye is evenly mixed with the product.
Ready plaster does not need mixing with water. Add color to the product and mix the solution with a construction mixer or a drill with a mixer nozzle. If after opening the package it was found that the composition covers a layer of water, the liquid must be drained. Water is added over the product so that the composition does not harden. Next, the product is connected to the color and mixed with a tool. Particular attention should be paid to the walls of the bucket. Material remains on them, so part of the putty is not painted.
