5 types of smoothing compounds
The smoothing compounds, depending on the type, can be used for both external and internal environments. Generally it is applied on the plaster to even out any dimorphisms due to a previous careless application or normal signs of the application of the plaster. Therefore, the smoothing compound for interiors is very useful for creating a uniform and perfectly smooth surface to obtain a well-done and aesthetically pleasing job.
Furthermore, interior finishing coats have a very specific function as they manage to make the wall more porous and suitable for accepting paint or wallpaper. In some cases it takes on a further very important function: it avoids the formation of condensation inside the rooms in order to prevent the formation of mold and fungi.
For outdoor environments
First of all, it is important to underline that the functions of smoothing compounds that can be used in external environments are almost very similar to those of smoothing compounds designed to be applied in internal environments. Consequently, smoothing compounds are usually used indifferently for both types of environments without the need for a clear classification.
However, it is also true that some products in this category have some differences that characterize them. One of these concerns the composition: that of smoothing compounds for exteriors is generally cement-based, rather than gypsum-based like those for interiors, as it is a material that is better able to withstand both climate changes and the impact with atmospheric agents or natural erosion due to time.
