Application of decorative plaster

Material requirements

The following requirements are imposed on decorative material:

• moisture resistance - this parameter is recommended to be taken into account if a decorative agent is used for plastering the facade or surfaces inside rooms with high humidity (pools, bathrooms);
• ease of application - this is important for DIY enthusiasts;
• color of the product - in this case they are guided by their own preferences, however, it should be borne in mind that some materials give a different tone after solidification;
• price - professionals advise choosing a product of the middle price category, since not everyone can afford too expensive a tool, and it does not always justify such a cost, and too cheap plaster is of poor quality.

It is enough to align the base and repair large defects. Small differences and minor flaws, the plaster will correct itself.
• Textured. Such products include mica particles, small pebbles and other fillers that form the original texture on the surface. Under such plaster, thorough surface preparation is also not performed. It is enough to make the base even and without large defects. The material is applied with conventional construction tools. The use of special devices is not required.
• Structural. They are a homogeneous tool. The product is applied to the surface, leveled, and then with the help of special tools create a relief, as in the photo below. To do this, use rollers or various techniques for performing the structure.
