A clean, polished finish when working with walls depends on getting exact and smooth edges. Perforated corners are useful in this situation. These useful instruments support and define the corners of walls, keeping them sturdy and sharp even after putty layers have been applied.
Selecting the ideal perforated corner for your project can make all the difference. With so many different kinds of materials and designs at your disposal, it’s critical to know what each kind has to offer and how it can meet your particular requirements.
For a flawless finish, knowing how to attach the corner correctly is essential after you’ve chosen it. This guide will assist you in navigating the options and procedures involved in using perforated corners for your wall finishing projects, regardless of your level of experience with do-it-yourself projects.
For putty work, selecting the proper perforated corner is crucial to producing crisp, straight edges and long-lasting durability in wall finishing. Taking into account material and application considerations, this article will help you choose the ideal kind of corner bead for your project and give you detailed instructions on how to attach it correctly for a polished look.

Types of painter"s corners
Because they are used to strengthen corners prior to decorative finishing during puttying or plastering, perforated corners are commonly referred to as "plasterers" or "painters." They accomplish two goals:
- Reinforce corners, especially external ones, give them additional strength and resistance to damage. It is no secret that protruding corners are more often than flat surfaces subject to chips, scratches and other mechanical influences, for example, when carrying large-sized furniture through a doorway.
- They allow you to easily and quickly arrange the joint of perpendicular surfaces, make it smooth and clear. This, in turn, makes subsequent finishing easier: gluing wallpaper or tiles in smooth, not “cluttered” corners is easier, the result is better quality.
Which kinds of corners exist?
Materials for manufacturing
To begin with, the kind of raw material used to make these products varies. Three primary categories exist:
- Galvanized steel. Strong, reliable, resistant to corrosion due to the zinc coating applied on all sides.
However, with prolonged use in a humid environment, they can cause rusty spots.
- Aluminum. Lightweight, durable, not subject to corrosion. But not resistant to close proximity to copper and some other substances.
- PVC (polyvinyl chloride). The price of these products is the lowest, and they have no fewer advantages than metal corners.
First of all, this is absolute inertness to the effects of moisture and aggressive chemicals – plastic corners are not subject to corrosion, do not rot, do not deform.
As a point of reference. PVC products are growing in popularity every year. Plastic perforated corners are available in a variety of modifications, such as those that come with serpyanka tape and those that have an adhesive substance applied to the interior surface to make installation easier.
Configurations
Two surfaces do not always have a straight joint line. It can take on very complex shapes when creating arches (see How to beautifully decorate an arch made of plasterboard), curved multi-level plasterboard ceilings, and other structures. It is just not possible to protect such corners with the above-mentioned products. For them, arched corners made specifically are created. The most common raw material used in their production is polyvinyl chloride, or plastic. Unlike a straight corner, an arched corner for putty has one of its sides cut into "petals," which enable it to be bent with any radius of rounding in any direction.
It is far more difficult to finish curved corners with a clear shape, especially if you lack the necessary puttying and plastering skills. You can accomplish this without any issues if the corners are arched.
How to install perforated corners
We will walk you through the process of using the mentioned products to finish corners by hand. Let’s consider the most challenging option: plastering where the workers neglected to keep the level and had to "bring out" the joints of window or door openings with walls.
Kindly take note. These issues typically don’t occur when plasterboard sheets are used to finish corners because of their smooth, even surface and the fact that the sheets are typically fastened to a frame that has been leveled. Using PVC corners with an adhesive inner surface makes the most sense in these situations.
Thus, installing corners, which is done in the following order, is the first step in puttying the corners of walls and slopes:
- Measure the length of each joint and cut the corners to size. Plastic corners are cut with regular scissors or a paint knife, metal corners – with metal scissors;
- To avoid thickening due to the overlap of corners, their outer side is cut at an angle of 45 degrees;
- Then a building level is applied to each side of the slope to determine the degree of its evenness and "tilt" in one direction or another. You can make marks on the wall to know where to apply more putty, where – less;
- Prepare the required amount of solution and apply it to the slope on both sides, but not in a continuous layer, but at intervals, focusing on the marks made earlier;
- Apply the corner to the slope on top of the putty slaps and press it lightly into it so that a small part is squeezed out through the holes;
- After removing the squeezed out solution with a spatula, use a level to check the verticality or horizontality of the corner. Achieve its correct position by pressing harder where required;
- Then the instructions require you to wait a while for the putty to set and fix the corner. After which you can putty the corner, filling the empty spaces with the solution and leveling the adjacent surfaces.
Suggestions. If the walls and corners are nearly equal, you can apply the finishing putty right away. Applying the finishing layer as a second layer after the starting one is preferable if they need significant correction.
Similar to a straight plane, the corner can be ground to the perfect smoothness (see How to grind walls after puttying and how to do it correctly). It is advisable to slightly round off and smooth the corner itself during the grinding process. This will help with subsequent finishing and increase its resistance to mechanical damage.
Type of Perforated Corner | How to Attach |
Plastic Corner | Apply putty on the edge, press the corner in place, remove excess putty |
Aluminum Corner | Secure with screws or nails, apply putty over it, smooth the surface |
Galvanized Steel Corner | Embed in fresh putty, align it, cover with more putty |
For putty work, selecting the appropriate perforated corner can have a big impact on the strength and longevity of your wall finish. A smooth, polished finish is guaranteed when choosing the right material and size, whether you’re working on internal or external corners.
It’s crucial to correctly attach the perforated corner in addition to choosing the appropriate one. You can get a perfect finish that lasts by doing the right things, like making sure the surface is clean and using the appropriate kind of putty.
By using these pointers in your wall finishing projects, you’ll not only save time but also enhance the strength and appearance of your walls. Even a do-it-yourself enthusiast can produce expert-quality results with the correct equipment and methods.
