Why is the correct selection of plaster of paris so important?

The construction of a new or renovation of an existing apartment is usually a very time-consuming task. One way to shorten it is to get enough building materials and tools in advance. A perfect example is putty. If we buy too little of it, finishing the walls will take us much more time. The best solution is to accurately calculate our need for this material. In addition to the amount, it is worth knowing the differences between the individual types of finishing coat. Only in this way will we be sure that we choose the right product to create a durable and visually attractive smoothing.

What is plaster of paris?

It is hard to find a better material for finishing walls during construction or renovation. While this material is now very popular, other substances have been used in the past. That is why in old buildings a cement-lime plaster was used. Due to the numerous disadvantages of this solution, the finishing coat is now the preferred building material. Due to the application of a layer of plaster, such a wall has a rough texture. Moreover, just after a few years of operation, such plaster begins to crack. So the appearance of the interior deteriorates very quickly. The putty is devoid of all these drawbacks. With its help, we can create a virtually flawless surface, which can then be easily painted or covered with wallpaper. There is no problem of dust settling in the porous wall texture.The plaster can be used both when constructing a new building and when renovating an old tenement house.

Usually, the basic element of such plaster is gypsum. Due to its properties, it has a filling and binding function at the same time. In addition, other minerals are present that slow down the setting of gypsum. It is thanks to them that we have enough time to calmly cover a given wall. In stores with building materials, you can find finishing coat in the form of a dry mix or a paste ready for immediate use. Individual types of plaster differ not only in price, but also in the correct method of application and where they should be used. So before we buy such material, we must make sure what type of plaster we need.Usually, the basic element of such plaster is gypsum. 

In what places is the finishing coat useful?

It depends mainly on the type of plaster we have supplied ourselves with. Individual types have specific parameters and properties that determine the optimal place for their application. The putty used for smoothing walls in the living room should not be used in the bathroom and kitchen. In addition to the nature of the room, the type of material from which the smoothed surface is made is of great importance. Gypsum finishing coat is most often used in living rooms. It is primarily about sleeping and living rooms. In turn, the relatively low price combined with an attractive appearance translate into the great popularity of gypsum plaster. Due to its adhesion, there will be no problems with applying such a plaster, regardless of the type of substrate. Such material is also useful for pointing plasterboards.Alternatively, consider using a gypsum-polymer mix if you need a more effective solution. Putty coats with gypsum composition are not suitable for proper functioning in humid conditions. The periodic humidity of the room cannot exceed 70%. So it is not worth putting this type of coating in the bathroom or kitchen.

What type of plaster will be useful for finishing the facade as well as our bathroom and kitchen?

A high level of humidity complicates the selection of the correct finishing coat. A special purpose mixture is needed. We can choose a lime mix, because we can easily apply a layer of latex or acrylic paint on it. In the case of ceramic tiles, we will need something else. The lime leveling plaster is not able to support the weight of such tiles. So if we want to install ceramic tiles on the wall of our kitchen, we will need a polymer plaster. Also called acrylic, it is a highly flexible substance. Thus, it better tolerates all loads and movements invisible to the naked eye. It is about ceramic tiles that have loosened over time.

When leveling the external walls of a building, both cement and lime screed will be equally useful. Resistance to weather conditions is the basis when finishing the facade. In the case of more decorative decorations, cement putty will be better. The calcium mixture is not flexible enough. On the other hand, such a material guarantees optimal air flow. The structure of the outer walls will not be susceptible to the development of various fungi and molds. In turn, the cement screed has water-repellent properties. This means that the wall covered with such a coating will not allow moisture to pass through. Facades secured in this way are distinguished by a high level of durability.
