Gypsum plaster and cement plaster are the two main types of materials used for leveling walls and ceilings in apartment renovation. However, despite the fact that they have a similar function, they differ significantly in their characteristics and application.
Gypsum plaster is a gypsum-based material that is used for interior finishing of premises. It has a number of advantages, such as high drying speed, low density, good heat and sound insulation, as well as the ability to breathe, that is, to allow moisture to pass through. Gypsum plaster is suitable for application on concrete, brick, aerated concrete and other materials. However, it is not recommended for use in damp areas such as bathrooms and kitchens, as gypsum absorbs moisture and may lose its properties.
Cement plaster is a more versatile material based on cement and sand. It is suitable for finishing both inside and outside of buildings due to its moisture and weather resistance. Cement plaster has a higher density and strength than gypsum plaster and is better suited for leveling large irregularities and creating a thick coating. However, it takes longer to dry and requires more time to prepare the mortar.
The choice between gypsum and cement plaster depends on the conditions and purpose of use.
If you need plaster for interior decoration of dry rooms, then gypsum plaster will be the best choice. If you plan to decorate the bathroom or the facade of the building, then it is better to choose cement plaster.
It is also worth considering the budget and the time you are willing to spend on the repair of the apartment. Gypsum plaster dries faster and is ready for further processing, while cement plaster requires more time and attention. The choice between these materials should be based on your specific needs and preferences.
