Plastering is one of the most important stages of interior finishing for the final result. It gives our walls and ceilings a smooth surface and a protective layer against mechanical damage. However, there are various plastering methods, each with its own advantages and disadvantages. The choice of one of them will determine the further steps of the process, such as, among other things, the decision to use a specific type of plastering corners. Get to know the different plastering methods better and find out why gypsum plaster and PVC corners are a perfectly matched pair!
What types of plaster are there?
Among the most commonly used are gypsum plaster i cement-lime.
Gypsum plastering is used most frequently in the interior of rooms. The advantage of this type of plastering is certainly ease of application. Gypsum plaster is flexible and really easy to spread. After drying produces a smooth and even surface. Thanks to its properties, gypsum plaster can be used on various types of substrate, such as concrete, hollow blocks or bricks. This type of plaster is shatterproof and provides a solid barrier against damage. Among the disadvantages of gypsum plaster it is worth mentioning the low resistance to moisture. Consequently, it is not recommended to use them in rooms with high levels of moisture, such as bathrooms.
Cement-lime plastering consists of applying a mixture of cement and lime to the surface. This type of plaster is characterised by greater durability and resistance to moisture than gypsum plaster. It is also more durable, making it suitable for use also on the exterior surfaces of buildings. However, cement-lime plasters are less flexible than those of gypsum. This can cause cracks to form more easily as a result of structural movements of the buildings. The application of cement-lime plaster is also quite time-consuming and requires more precision and accuracy.
You already know the types of plaster, so it's time to start choosing the right one. It will certainly depend on your needs and the effect you want.
Gypsum plaster and PVC corners
If you opt for gypsum plaster, it is worth bearing in mind the the use of appropriate plastering corners. They play an important role in securing and aesthetically finishing the outer edges of walls. Traditionally used corners, i.e. steel are increasingly being replaced by PVC corners. These steel is more susceptible to corrosionwhich can lead to rust and unsightly streaks on the walls. Steel corners are also less flexible and somewhat more difficult to install.
All these properties make They are increasingly being replaced by PVC corners, especially when plastering. Why?
- PVC corners are moisture-resistant - This is particularly important in the case of gypsum plaster, the composition of which includes water. Combining such a composition with steel corners could result in rust formation.
- PVC corners are flexible - are easily modelled, which makes it easy to adapt them to different corner shapes. Gypsum plaster is equally flexible, so it is worth using this combination when plastering non-standard edge shapes.
- Fitting PVC corners is easy - requires considerably less time than steel corners. It's a good combination with fast gypsum plastering, especially if you care about the time and efficiency of the process.
- PVC corners are resistant to mechanical damage - in duet with scratch-resistant gypsum plaster, this will provide effective and long-lasting protection for the wall edges.
