Plaster defects

Plastering is a crucial step in wall finishing because it leaves surfaces even and smooth, making them ideal for painting or applying wallpaper. Nevertheless, plastering isn’t always perfect, just like any other building process. Sometimes flaws in the plastering process can be seen that compromise the walls’ longevity and aesthetic appeal, even in the best cases.

Cracks, uneven surfaces, and even blistering and peeling are common flaws in plaster. These problems can be annoying, particularly if you’ve worked hard to achieve a polished finish. Knowing what causes these flaws is essential to both preventing them and knowing how to correct them when they do arise.

Plaster defects can arise from a variety of causes, including inadequate preparation, improper mixing, and environmental conditions. You can make the required preparations to guarantee that your plastering job endures and retains both its structural integrity and visual appeal by being aware of these possible issues.

Plaster defects and their correction

It is essential to understand the reasons behind their emergence, how to get rid of plaster flaws, and how to fix any damaged areas. It’s critical to assess the plaster’s strength before replacing it. The choice to replace the plastered surface is then made. The issue area can be examined in a few different ways:

Using a scraper or spatula to identify a plaster flaw is the simplest method. The instrument is used on the wall’s surface. Cosmetic repairs should be made where cement crumbs start to crumble.

A hammer can be used as a tool to find and remove applied layer defects. The wooden handle of the tool is being tapped on the surface. where the unstable surfaces will seem to be replaced by a deaf response. It is advised by experts to replace the plaster on the entire wall if there are numerous problem areas.

If damp spots are found on the wall that differ in shade from a dark color, the problematic area needs to be avoided.

Crucial! The impacted area needs to be crossed within a 500–700 mm radius of the damp center in addition to replacing a damp piece.

Using a knife to lightly press the surface and draw along it, you can assess the layer’s quality. If there are fissures, the water inside them either evaporates or drowns. Both cosmetic repairs and an expansion of the problematic area are required.

Inspection of plaster

The "Insulating and finishing coatings" section of SNiP 3.04.01-87 contains the quality requirements. Defects can be found and identified with the aid of a linear laser level. Where the laser plane should appear on the wall, the laser line is projected onto it. As such, it is possible to measure both the surface’s vertical and horizontal deviations. There are currently two recognized techniques for determining a wall’s evenness:

1. On a large area.
2. On a small area.

Any wall’s durability and appearance can be completely destroyed by plaster flaws. These defects, which can include bubbles, cracks, or uneven surfaces, are frequently brought on by improper application, inadequate preparation, or external circumstances. Determining the root causes and devising solutions is essential to attaining a seamless, durable finish. This post will walk you through common plaster flaws, how to avoid them, and efficient repair techniques to keep your walls in excellent shape.

Types of plaster defects

There are two kinds of defects, as we have mentioned previously.

1. Technological defects.
2. Operational defects.

The first show up when building codes and recommendations are broken. The appearance of tiny growths, or bumps, on the treated wall that are distinguished by the presence of white spots in the center—puffs—is the most prevalent defect of technology violation. Below, we’ll discuss them and how to overcome them. We only observe that dutiks emerge during the non-contained lime solution preparation process.

The second ones are peeling and plaster cracks. They may develop as a result of wear over time. Cosmetic repairs may be required in addition to routine preventive inspections to keep the plaster from crumbling. Experts advise working while the entire apartment is being renovated.

Thus, let us examine each issue more closely and determine the "technical treatment of the walls."

Dutiks

Using an iron spatula, thoroughly clean the areas where the bumps are located in order to remove them from the plaster’s surface. After that, cover the treated surface with the solution.

Cracks in the plaster

There could be a variety of causes for the development of plaster cracks. The most prevalent flaw is this one, which arises from improper surface preparation. It’s possible that the working solution’s ingredients weren’t sufficiently combined. If the applied solution was applied to a wall that was not reinforced, an overly thick layer of it may have contributed to their appearance. The only way to prevent this phenomenon is to carefully combine the gradients of the upcoming solution.

Swelling and excavation of plaster

Although it is not frequently discovered, the flaw can occur. Maybe the technology was disrupted when plastering raw surfaces because there wasn’t enough time for the layer to dry out. If the basis was excessively damp, a defect might appear. There is "disease" here.

Cracks in luzgi

Emerge from poorly prepared joints between various materials, such as brick and gypsum or wood and concrete. Rewinding is one way to get rid of small cracks; this will be covered in more detail later on.

Large cracks need to be "cut off" by thoroughly wetting the affected area with water while using a steel brush to clean it. then apply a fresh layer of solution only after that.

Drange modifies new compositions following the processing of defective areas: a low-quality layer must be removed.

Vysols

High humidity causes valles, or as they are also called, to appear. This is a warning sign for inadequate ventilation; if you ignore it, you might eventually find mold and fungus growing on the wall.

This phenomenon is something you can combat. You should try putting the deposits in water to dissolve them. You must employ unique tools in the battle, which are constantly accessible within the retail network. In the process, rollers, brushes, and metal scrapers are used.

And also

The building’s facade needs to be hydrophobized in order to be protected. This is the wall being treated with a unique solution.

Crucial! The mixture must be frost-resistant, water-repellent, and airtight.

When the wall is frequently impacted by water, comprehensive actions must be taken.

This is particularly crucial for regions that experience higher precipitation rates. The operational life of walls treated with water repellents is at least ten years. Water emulsions, water-soluble mixtures, or organized components are used to protect bricks.

To achieve a smooth, long-lasting finish, it is imperative to comprehend common plaster defects. Early detection of problems such as blistering, cracking, or uneven surfaces allows you to make corrections before they worsen.

To avoid these flaws, proper technique and preparation are essential. Make sure surfaces are tidy and ready, and adhere to suggested plastering techniques at all times. By paying close attention to details, you can steer clear of common pitfalls and guarantee a high-quality outcome.

Recall that most defects can be fixed with the appropriate approach, even if they do occur. Not only will timely and accurate problem solving enhance the look of your walls, but it will also increase their longevity.
