Plaster corner with mesh: what is it for

Every little detail matters when it comes to painting your walls, and corners are no different. You may be wondering how to maintain the sharp appearance of your walls if you’ve ever noticed damage or cracks near their edges. The use of mesh plaster corners is one practical remedy. This clever method can improve the longevity and polish of your walls in addition to being aesthetically pleasing.

Applying a reinforcing mesh along the corners prior to plaster finishing is known as plaster corners with mesh. By serving as a supporting layer, this mesh helps to disperse stress and stop cracks from forming. What was the outcome? stronger, smoother corners that can withstand daily abrasions. It is particularly helpful in areas with heavy traffic or where walls meet at a 90-degree angle.

This technique not only makes your corners look cleaner and more polished, but it also strengthens their structural integrity. Using mesh reinforcement at the corners will help you achieve a perfect finish that won’t peel or crack over time. The quality and longevity of your wall finish can be greatly improved by understanding and utilizing plaster corners with mesh, whether you’re starting from scratch or remodeling an existing space.

Purpose Plaster corners with mesh help reinforce and protect the edges of corners from damage and cracking. The mesh adds strength to the plaster, making it more durable and long-lasting.
Application These corners are applied during plastering to ensure that the corners are sharp and well-defined. The mesh is embedded in the plaster to prevent movement and cracking over time.
Benefits Using mesh in plaster corners enhances durability, reduces the risk of cracks, and ensures a clean, professional finish on walls.
Maintenance Once the plaster is dry and set, maintenance is minimal. However, if damage occurs, the corner may need to be repaired by reapplying plaster and mesh.

Methodology for performing plastering work

There are two types of plaster mesh corners: the inner and outer corners. Other materials include metal and plastic. The material and shape of the surface to be finished will determine the selection.

If you are able to do all of the work yourself, the cost won’t be too high. Now let’s examine several approaches to completing the task.

Finishing internal corners

Finishing internal corners during plastering walls can be done in two different ways:

  • Joining the treated and faced walls,
  • Carrying out work on plastering two walls at the same time.

Note: In both cases, the mesh plaster corner will be utilized. It will enable you to considerably strengthen the corner and keep it oriented in the proper geometrical manner.

  • Throwing on the splash and a layer of primer (see. Why do you need a primer: technological nuances of finishing works) is carried out according to the classical method, leveling is carried out using a rule, starting from the corner and further along the wall. Then they begin to form the corner, for which they make markings in the form of scratches on the surface of the solution.
  • The float or trowel must be applied with the edge to the previously plastered wall. The angle should be approximately 30 – 40 degrees. Then you need to bring it to the inner corner, lay it on the recently tiled wall surface and rub it down. The movements should be up and down. After this, the tool should be laid with its base on the newly plastered surface, pressed with its edge against the tiled wall.
  • Making movements with significant pressure, they clean it from the plaster mixture. You need to wait for the primer to harden, and then apply the final layer – the top coat – to its surface.
  • Smoothing the final layer of the top coat is carried out using a wooden or foam float. In this case, you need to ensure that no bubbles, depressions or protrusions are formed. It is important to achieve an even coating of the entire wall.
    At the final stage of processing the corner, the float must be held so that its lower edge lies on the tiled side, and the corner slightly touches the newly plastered surface.
  • The tool must be moved up and down along the entire length of the corner. The result of the measures taken will be a strictly verified edge between two adjacent walls.
  • The same method is used to process two adjoining walls.

Note: It’s worth investing in an angle spatula to smooth the mixture. You’ll be able to preserve the corner’s proper geometry in this way.

Finishing external corners

There are two ways that external corners are processed. They are appropriate for both construction and repair work.

  • The first method of processing uses an angular profile, made of metal. This allows you to plaster both adjacent walls at the same time, while achieving high strength of the corner.
  • With the second method of processing, the work is divided into two stages. Both sides of the corner are plastered in turn.

Note: It is easy to achieve an outer corner of the wall with a smooth surface and great durability thanks to the mesh plaster corner protection profile.

  • Both sides of the metal profile are attached to its central part and are meshes. Their thickness depends on the model of the rail. Fix the profile with a regular solution and let it harden. After that, apply a primer layer.
  • The corner rail can be installed on a small layer of plaster. To do this, apply the solution starting from the floor and up to the ceiling. This will simplify the work of leveling the profile. Any metal corner profile can be easily shortened if necessary.
  • Shelves – meshes can be easily cut with metal shears, and the central part can be sawed with a saw. The installed rail can be used as a beacon when smoothing the primer layer.
    The hardened solution is cut using a steel trowel.

Note: By doing this, you can make room for a layer of cover, which is applied in the traditional manner. The thickness is exclusively determined by the corner profile. The corner is processed with fine sandpaper to give it a rounded shape.

Finishing slopes

The surfaces of window and door openings that are 90 degrees off the wall are known as slopes. It is important to keep in mind that the depth and thickness of the applied plaster layer must remain constant when working on slopes that require plastering.

Note: By doing this, you can make the visible portion of the door or window opening a consistent width throughout. With a metal corner profile, the slope can be made to the same depth. It is equally spaced from the window or door frame’s upper and lower surfaces.

It is preferable to use a specific template when finishing slopes in order to achieve a uniform thickness of the plaster layer.

Techniques for completing hills on your own:

  • At the initial stage, work is carried out to clean and prime the entire working surface.
  • After the primer layer has dried, you should begin applying plaster to the slopes. To do this you need to use a spatula.
  • To get straight corners, use metal corners. They are attached to the surface using plaster and covered with. You can also use a template to achieve a smooth surface.
  • As soon as the plaster layer hardens, the entire surface of the slopes is cleaned using sandpaper.

Common mistakes when plastering

Let’s examine the most prevalent errors in chronological order:

  • Start plastering work without assessing the technical condition of the base. Because of this, in the near future you may encounter such a nuisance as cracks and peeling of the plaster layer. This means that there will be a need to repair the cladding.
  • Apply the coating, ignoring the primer layer. This will lead to the fact that when drying, the outlines of the building materials from which the building is constructed may appear on the walls.
  • Apply a gypsum-based topcoat directly to a porous concrete block base. These building materials do not interact very well with each other, which can cause numerous cracks in the plaster layer. Here, it is better to use a topcoat where a polymer acts as a binder. You can use ready-made gypsum plaster, which contains all the necessary substances.
  • Long time intervals between plastering ceiling surfaces (see. How to plaster a ceiling), walls, window slopes and doorways. Work must be carried out without long breaks so that each layer sets equally smoothly over the entire area.
  • Align the walls with plaster on a concrete base with a moisture content not exceeding 4%. The plaster solution will not adhere to the concrete surface.
  • Failure to comply with the rules for plastering corners located on slopes. It is recommended to supplement the joints of the plaster coating with the box or frame with expansion joints. Before starting work, expansion slats should be attached to them.
  • When the outer corner is located in places with intensive traffic, it is necessary to install a steel or aluminum profile on it. If you ignore this recommendation, the corner may be significantly damaged during operation.
  • Cut galvanized profiles using a grinder. This method will lead to the destruction of the zinc coating, which serves to protect the slats from corrosion. In the future, red spots from rust will form on the cladding. Therefore, the profile can only be cut with scissors and a hacksaw for metal.

Smooth, long-lasting corners in walls require a plaster corner with mesh. As a layer of reinforcement, the mesh helps to stop potential damage and cracks over time. The mesh is firmly bonded and the finish is smoothed out by embedding it into the plaster, giving your corners a polished appearance. This method not only extends the life of the plaster but also makes your walls look better overall.

Using mesh plaster at the corners is a crucial step in maintaining the durability and attractive appearance of your walls. Since the corners of your walls are frequently the weakest areas, this technique gives them additional strength and stability. Using a mesh helps stop chips and cracks, which happen frequently when a house settles or the walls get worn down.

Plaster application is also more even and smoother when mesh is applied in the corner. It forms a firm foundation that improves the plaster’s adhesion and durability over time. In the long run, this will save you time and effort because there will be fewer touch-ups and a longer-lasting finish.

All things considered, anyone wishing to improve the strength and aesthetics of their walls would be wise to use plaster mesh in the corners. It’s a straightforward but powerful technique that ensures your walls not only look great but also withstand regular use.
