Although plastering corners is a difficult part of home improvement, it is necessary to get a smooth, polished wall finish. Correct technique is essential for durability and aesthetics, whether you’re working on an external corner in a hallway or an interior corner in a bedroom.
You must choose the right kind of corner bead before plastering a corner. These beads serve as a framework to guarantee that the plaster adheres correctly and is shielded from future wear and tear in addition to helping define the corner’s sharpness. The first step to creating a flawless corner is selecting the appropriate bead and placing it properly.
Plaster is applied in layers during the plastering process in order to create a smooth, uniform surface. For the finish to be strong and to avoid cracking, each layer must be given enough time to dry completely before applying the next. A professional appearance can also be attained by becoming proficient with the use of your plastering tools, such as trowels and hawks.
Plastering corners can be made easier with the right techniques and a little patience. A perfect finish can be attained by practicing your technique, selecting the right materials, and comprehending the basics of plastering. If you’re a professional looking to hone your skills or a do-it-yourself enthusiast wanting to learn how to plaster corners, this article will walk you through the steps and advice you need to master the technique.

Types of the product
It is easiest to align corners with plaster using corners, as demonstrated by video tutorials. Both experts and novices use this building material. The products make it easier to accomplish expert finishing with your hands. It is advisable to acquaint yourself with the attributes of various product types to enable you to make an informed decision.
Metal corners
Aluminum and steel are used to make metal corners. Every choice has benefits and drawbacks.
The strength of aluminum material has increased. Such a corner has a long service life and is mildly prone to corrosion. Because the material is lightweight, installing the product is made easier. Additionally, light weight does not add to the surface load, extending the surface finish’s lifespan. An additional benefit is a reasonable cost.
Because steel products are prone to corrosion, the material is galvanized during the manufacturing process. Although zinc resists rust, it is susceptible to deterioration. Use metal scissors to trim the corners to avoid this happening. This is not the use for a grinder. To avoid damaging the galvanized layer, it is advised to install the material carefully.
Only latex composition or gypsum plaster is used beneath a metal corner.
Plastic products
A plastic corner leveler for a plaster layer is a sturdy, lightweight product of excellent quality. Because the material is lightweight, it does not add weight to the structure. The product is not as strong as a metal product, but it is easy to use and resistant to moisture and alkalis.
Types of structures
Plaster corners come in various varieties.
Right corners
They are made of plastic or metal and are a strip bent in half with 90-degree edges. Wall thickness for metal products is up to 0.5 mm, and for plastic products it is between 1-1.5 mm. Generally, the edges are where holes of various configurations are made. This lowers the product’s weight, lowers its cost, and increases the material’s adherence.
Arched products
These corners are made entirely of plastic. Products have curved internal and external corners in their design. The product has a strip on one side and a segmented corner on the other for convenience of fixation.
Universal product
The product has non-standard corners because it is made of plastic and has a mesh structure. Metallized tape that forms corners and is non-woven are also included in this category of products.
Non-woven tape is a five-centimeter-wide paper strip with microperforations. You can bend because there are slits all the way along the length.
Metallized tape consists of a 5 cm wide perforated strip of paper with 1 cm long metal strips on both sides of the product.
As the video instruction demonstrates, both products are meant to be used for plaster corner leveling. Metal and plastic corners are analogous to tapes. These products work well with corners of any arrangement.
Products with a mesh
It’s a corner, like in the picture below, with reinforcing mesh attached to its sides. The product is used when applying a thick layer of material or when the finishing is done by wet plastering the surface. The mesh has a width of 2-4 cm. The corner is formed out of either plastic or metal.
Combined corners
These products are corners that have a plastic net with a reinforcing mesh when the corner functions as a metal component. The product makes it possible for you to precisely outline the inner corner and design the joints of the building base.

Correctly plastered corners give walls durability and structural integrity in addition to improving their aesthetic appeal. With the correct tools and adherence to a few essential steps, even novices can produce durable, well-groomed corners.
