Types of corners for plastering work

Achieving clean, well-defined corners during plastering is crucial for a polished appearance. Whether you’re working on external surfaces, interior walls, or ceilings, the type of corner you use can greatly impact how your project turns out and how long it lasts.

Plastering uses a variety of corners, each intended to meet particular needs and overcome particular obstacles. Some are designed to add decorative elements, some to guarantee straight lines, and still others to reinforce the edges. Knowing the differences between these varieties will enable you to select the one that best suits your requirements, guaranteeing both style and functionality.

The options can seem overwhelming, ranging from common square corners to more specialized choices like bullnose or bead corners. But if you understand their uses and goals, you can confidently take on any plastering task. Let’s examine the various kinds of corners and how using them can improve your plastering.

Type of Corner	Description
External Corner	Used for outward-facing edges, providing a clean finish to the outer angles of walls.
Internal Corner	Used for inward-facing angles, ensuring a smooth transition between connecting walls.
Rounded Corner	Provides a softer look with rounded edges, often used for decorative purposes.
Reinforced Corner	Strengthened with metal or plastic for durability, commonly used in high-traffic areas.

Knowing the various kinds of corners when plastering is essential to getting a polished finish and guaranteeing longevity. The three primary varieties—external, internal, and curved—all call for particular methods and supplies. Internal corners must be carefully smoothed to prevent cracks, while curved corners add an attractive touch that calls for flexible materials and deft application. External corners require corner beads for protection and clean edges. Your plastering projects will be of higher quality and last longer if you know how to handle each type.

Types of corners to perform plastering work

Currently, this device is available in a wide variety of forms on the market. You must examine them all to determine which ones will work best with a particular kind of plaster work.

The materials used to make putty and plaster of angles are used to categorize the lay-ins. chosen plastic and metal.

Use of corners for plastering will ensure that the joint is finished correctly when aligning the walls.

Models made of metal

Several kinds of metal are used to construct the plastered metal angle. These metals are listed below:

Galled steel gives devices for angles with special strength, but also makes them more heavy in weight than other types. It has an important drawback, after time it can be covered with rust, especially in those places where plaster can become thinner. In such places, moisture may fall into galvanized steel that will damage it. You can avoid rust, paying special attention to the installation of corner elements. During installation, it is important to leave the cladding whole, without defects, and carry out the pruning only with scissors for metal;

Although galvanized steel gives angles devices a unique strength, it also makes them heavier than other kinds.

Another way that metal models differ is in their shape:

The most popular are the standard form, they are made straight with a bend of 90 degrees. There are 0 thickness.4 millimeters. Perforating the product on the sides so that the weight becomes even easier. And this contributes to better clutch with the solution;

Experts stress that metal products are not easily coated in rust, and that this disadvantage is made worse by exposure to acids and alkalis. As such, it is advised that they be used exclusively when working with acrylic, latex, and gypsum mixtures.

Models made of plastic

Recently, the corner for plastic angles has gained a lot of popularity. There are plenty of them; the most well-known ones are listed below:

Conventional overlays, the same shape as metal, but their plus is that plastic is not subject to corrosion. Plastic is used only of good quality. They are perfect for rooms with a high moisture level. Minus in the large thickness of the product, although they usually try to plastering not with a thick layer. To close the overlay, a layer of 3 millimeters is enough;

To incorporate them into a thick layer of plaster mixture, utilize mesh plastic corners.

The primary benefit of these plastic products is that they are resistant to rust. Despite the fact that metal is a more resilient material. The plastic is still more widely used.

Mounting the plaster angle

After deciding on the corner shape for plastering, it’s a good idea to research the installation guidelines. The durability of the coating is guaranteed by proper installation. The following postulates will be provided:

• A strong wall should be at an angle;
• The angle is primed in the same way as the surface itself;
• The corner is attached to the beacons;
• The mixture should penetrate into all perforated holes;
• To install the product vertically, it is worth using the level;
• With an excessive thin layer of plaster, you can fix the angle with dowels or self -tapping screws;
• The corner parts are plastered last;
• Work should work with special tools designed for angular work;
• Rub these areas in turn, monitoring the corners do not protrude.

Any leveling composition or sealant is used to close the corner lining if the solution is unable to completely close it.

How to use corner linings for plaster

Installing corner overlays correctly is important, of course. Their understanding of the work’s characteristics and stage will make it easier for them to complete the task. We will go on to describe the work with varying slopes and angles.

Finishing the internal corners

You can complete the internal corners one at a time or all at once, but in either case, carry out the following tasks:

1. Spray is pounced and a primer is applied, equal to the wall by the rule, acting from the corner and further. Followed by the corner, making the mixture on the mixture.
2. The cell is applied to the edge to the surface, at an angle of 30-40 degrees. Then it is brought to the inner corner, laid on the wall and is grouted up and down. Further, Kelma is attached to the freshly plastered wall with the base, and pressed by the edge.
3. Tightly pressed on the tool, thus, it is cleaned. After drying the primer, apply an cover.
4. The covering is efficiently aligned with a grater. At the end of processing the corner of the walls of the grater is located so that its edge is on the plastered side, and the corner slightly touches fresh plaster.
5. The device is moved up and down the entire corner, as a result, they get a strictly verified rib between the walls.

Finishing the outer angles

They also take one of two actions in this portion of the finish. Initially, they utilize metal angular profiles, which facilitate simultaneous processing of both sides. In the second, walls are processed one at a time.

1. The metal profile is attached with a plaster mixture, after its drying, the surface is primed.
2. The corner rail is fixed on the thin layer of the mixture. The mixture is lubricated from the floor to the ceiling. If necessary, the profile is cut off with scissors for metal so that its length corresponds to the length of the wall.

Roading slopes

The 90-degree corners of window and door openings are known as slopes. Plaster must be applied with the same depth and thickness on slopes. They act in phases so that this can work out:

• First, the surface is cleaned and primed;
• The plaster is applied to the dried surface of the slopes;
• Install the corners for slopes for plaster, and soak them from above;
• On a dried surface, stripping slopes are carried out.

Grunting of planes and alignment

Plaster work started after the solution was applied, to which the overlay was attached.

Start by leveling the wall all the way through, making sure not to go over the four-centimeter gaps. Additionally, a solution is applied adjacent to the corner lining and the excess is removed by smoothing out the rule. Once the half-length has passed, the same actions are performed. Make sure the corners do not protrude outward when aligning the connecting surfaces.

An internal corner spatula is designed specifically to level surfaces of this kind to a high degree of quality. They perform polymerization and grout after the wall has dried.

Turn each corner into a grinder. To prevent chips, it is important to make sure the heifer does not damage or remove any of the material around the edges. The inner corner overwhelms the sponge grater.

Errors characteristic of plastering

Inexperienced workers might make costly mistakes because they are unaware of all the details involved in the task. It is important to be aware of these errors to avoid having your work altered. Thus, the most typical errors are:

• Proceed to work without assessing the technical condition of the surface;
• Ignore the application of the primer, without it, the material of the built building can manifest through the layer of the mixture;
• Carry out work on plaster on different surfaces after a long period of time;
• Do not use at the outer corners located with the strong passage of metal profiles, without them, it is possible to further damage the surface;
• Cut galvanized profiles using a grinder. Bulgarian will damage zinc coating.

It is impossible to overlook the primer application because, in the absence of it, the built-in building material may show through the mixture layer.

Corners are useful and convenient, and their use will strengthen the plaster. It is important to decide on the view that will be used first. The homeowner will be happy for a very long time when the desired outcome is achieved by acting and adhering to the work rules.

Comprehending the distinct varieties of corners in plastering is essential to attaining a polished and long-lasting outcome in any construction endeavor. Every kind of corner bead or profile has a distinct function that improves the plastered corners’ strength, longevity, and appearance. Selecting the appropriate corner style guarantees that the edges stay safe and presentable whether you are working on external or interior walls.

Because they are durable and simple to install, metal corner beads are used extensively. They are perfect for places with lots of traffic where walls are easily damaged. Contrarily, plastic corner beads are flexible and moisture-resistant, which makes them ideal for damp spaces like kitchens and bathrooms. Flexible corner beads offer the required versatility for those working with curved surfaces without sacrificing strength.

Paper-faced corner beads are a common option for plasterers looking for a finished product that is flawless and smooth. They blend in perfectly with the plaster, reducing the amount of touch-ups and additional sanding that is required. Architectural corner beads are useful when exact alignment and sharp edges are needed. They give a space a clear, polished appearance that improves its overall appearance.

The particular requirements of the project, the kind of plaster being used, and the site’s environmental factors all play a role in selecting the appropriate corner bead. You can improve the caliber and durability of your plastering job by becoming knowledgeable about the different options available to you. Time spent choosing the right corner solution eventually pays off with well-maintained, aesthetically pleasing corners that look good for years to come.
