Plastering wall corners

Although plastering wall corners can be challenging, it’s necessary to achieve a polished, seamless finish. Whether you’re building a new home or renovating an existing one, knowing how to plaster corners will significantly improve the appearance of your walls.

Patience and meticulous attention to detail are necessary to get the corners right. Corners can be more difficult to work with than flat surfaces because they must be sharp and straight, free of any bumps or uneven sections. Here’s where using the appropriate tools and applying caution come into play.

We’ll walk you through the plastering of wall corners in this post, providing helpful hints and detailed instructions to help you get the greatest results. You’ll be able to confidently take on corners and produce a faultless finish that elevates the space as a whole with a little practice.

How to plaster wall corners

You must decide in advance how the corners will be leveled in order to plaster them correctly. Which option you select will depend on how you plan to finish the walls with your hands afterwards.

Leveling is required when tiles originate from:

• ceramics;
• porcelain stoneware;
• clinker.

Additionally, if you intend to adhere wallpaper to the walls with a joining pattern, accurate alignment is required. This technique is also employed in the event that decorative plaster is used for the cladding or if the wallpaper lacks a joining pattern.

To create even corners, you should choose ahead of time what kind of facing mixture to use. Plaster is required if the walls are to be completed outside or in a room with a lot of humidity:

• cement;
• lime;
• polymer.

Dry rooms can also make use of the types mentioned above. But when plastering with gypsum, there’s also the option of rounding the corners. If 90-degree plastering is required at the corners, this method works well. However, the material is not moisture-resistant.

Surface preparation

The surface of the walls must be prepared before processing.

How well the facing mixture fits and how long the finish will operate are determined by proper preparation.

The process of getting ready for internal and external corners is the same.

There are various steps involved in preparation:

• removal of the previous coating;
• check for unevenness (a construction square is used to complete the task);
• using a fishing line, it is determined what thickness of the material layer will be needed.

The plaster layer will be thicker than two centimeters if the wall is angled unevenly. Plasterboard is a better material to use in this situation. A chisel is used to remove any bulges and bumps that may be present. You’ll need the same mixture to remove the depressions. It stays in place until it solidifies, filling the indentations. After that, you can start to finish.

Tools and devices

You’ll need a wide variety of tools to complete high-quality finishing. On the list are:

• angle profile;
• trowel;
• square;
• rule;
• level;
• beacon;
• grid.

Use an angular or straight spatula to apply plaster to small areas. You can use half of the sandpaper at a time to wipe the walls. Steel, polyurethane, or wood can be used to make it. You can use it to level the solution or apply it.

The blend is made in a unique container. A construction drill fitted with a mixer nozzle is used to pound the mixture. Moreover, a specialized grater can be used to clean and polish the surface.

Although plastering corners of walls can be challenging, with the correct methods and equipment, you can produce crisp, clean edges that give your walls a polished appearance. This post will walk you through every step of the procedure, from plaster application and smoothing to corner preparation, guaranteeing a perfect finish each and every time.

Working with internal angles

The plaster of the internal angles is associated with more complex work than when decorating external. The finish method depends on whether it adjoins the facing surface or not. The first version requires plaster only one surface.
for applying the solution, the usual method is used. To level the solution, the rule must be directed to the wall. Simplifying the task can be a corner for plaster.
The even joint is formed thanks to the outbuilding and grater. With their help, it is gradually rubbed down. Rubbing is done with the usual movements from top to bottom, and vice versa. You need to make sure that the edge of the float is pressed against the plastered surface.

If you apply too much pressure to the float, the extra layer will be removed.

Only after the solution has solidified can the last layer be completed.

A foam or wood float is used for the last phase of the process. This time, the planes are rubbed using circular motions. Once there are no more pits or bumps visible on the surface, you should stop rubbing.

Working with external corners

It is necessary to align the external corners prior to cladding. You can use an aluminum corner for plastering purposes in this task. It contributes to a seamless joint. It further shields the outside corners from potential harm.

There are multiple steps involved in plastering the exterior corner. An application of gypsum mixture is made in the first step. Then the necessary length of corners is attached. You have to apply pressure in order to fortify them. They are fastened all the way around the surface that has to be leveled. The surplus mixture will be extracted via the holes in the aluminum corners. A spatula can be used to remove it. The mixture can be changed after it dries. To complete this task, an abrasive material is used.

Beacons are placed in order to obtain an even coating. They then line up at a 90-degree angle. A laser level or square is used for this. Filling with the mixture is the last step.

Without reinforcement

One option is to use a flat board in place of reinforcement. The board needs to be taped before installation in order to prevent it from sticking to the surface. Next, screws must be used to secure it along the slope from above and below.

You can then apply the plaster mixture after that. Distribution moves are made in the direction of the corner, working top to bottom. It is not possible to remove the board before two days have passed. The same procedure is then used to attach it to the other side, and the steps are repeated.

With a plaster corner

When you utilize a perforated corner, you can:

• provide protection for slopes;
• prevent accidental chips;
• ensure strength and evenness.

You must measure each corner’s length, add up the results, and then calculate the amount of material required.

Partially plastered corners should be purchased with a reserve because it is anticipated that they will be damaged during the work.

The secret to getting a professional finish is to get the corners of your walls just right. Anyone can create neat, sharp corners that improve a room’s appearance with the right tools, techniques, and careful preparation.

Recall that persistence and focus on details are crucial. By taking your time and making sure every layer is evenly distributed and smooth, you can prevent common problems like uneven surfaces or cracking.

Plastering corners will become second nature with practice, giving your plastering projects a polished appearance and producing a finished product you can be happy with.
