How to choose a construction rule for plaster?

Selecting the appropriate plastering construction rule is essential to getting a level, smooth facade finish. To guarantee that the plaster applied to walls or ceilings is even and consistent, a construction rule—also referred to as a screed or straight edge—is utilized. To get results that are of a professional caliber, this tool is essential.

Take the material into consideration when choosing a construction rule. Aluminum rules are perfect for outdoor use because they are lightweight and corrosion-resistant. They last a long time because they are also simple to maintain and clean. As an alternative, stainless steel rules are strong and appropriate for plastering tasks requiring a lot of force.

Another crucial element is the rule’s duration. Larger surface areas benefit from longer rules, like those exceeding two meters, since they help keep straight lines for a longer distance. Shorter rules—roughly one meter—are easier to handle and better suited for smaller, more complex spaces or tasks.

Make sure the profile of the construction rule is flat and straight. By doing this, you can minimize the need for rework and achieve a professional finish by ensuring that the plaster is applied evenly across the surface. Verify that the rule’s edges are straight and free of any bends or other flaws that might interfere with the plastering process.

Description of the tool

One of the most widely used measuring instruments in the construction industry is the rule (also referred to as "construction" at times). To gain a deeper comprehension of this device, it is essential to examine the term’s etymology, which originates from the word "correctly." Any specialist, even a novice master, can perform finishing work correctly and minimize the chance of error if they have such a tool available.

Today, this incredibly helpful tool can be found practically anywhere on a construction site, which is largely due to its extremely straightforward design. As you inspect the plane, you can actually find any flaws on the rail because it is perfectly flat.

The Wooden Rule is the most economical, though its metal equivalent is now available for purchase. Originally, the primary purpose of this tool was to make sure that various types of planes were free of dents or bulges. The rule is still applied for this purpose today, but it is also used in other works.

The scope of application

The rule can be made from wood or metal, as was previously mentioned. When you first look at them, they might appear to be nearly identical rails. Despite what you may believe, there are distinct distinctions between them. If you apply plaster with a wooden rule, it won’t be fit for use the following day.

It is common knowledge that plaster is diluted with water to the appropriate consistency prior to use. When the rail comes into contact with the composition, it loses its original form and the tree absorbs moisture. Its even edges might become arcuate as a result of deformation.

However, if the master applies the rule from the metal—typically aluminum—during the finishing work, this won’t occur. Not only is a similar tool highly useful, but it’s also simple and convenient to use. It will not, of course, lose its original form even after repeated use unless it is seriously impacted by mechanical forces.

Keep in mind that the rule is not limited to plaster application. This device’s range of applications is extremely broad. It is applicable to:

• laying tiles, where strict requirements for observing the plane relative to the horizon and vertical are presented;
• applying soft elastic putty. Here the rule is used as a large spatula;
• creation of screeds. Using this device, it is very convenient to level the solution on the floor;
• Ceiling devices. Similarly, the rule will be able to help create a flat surface on the ceiling.

Both the wooden and the metal versions of the rule are actively used in the construction industry, despite some differences between them. When performing tasks where there is little to no contact with moisture and unrestricted use of metal, the wooden rule is typically employed.

Features of use

The difference in model dimensions is one of the primary characteristics that enables Classify building rules to be classified amongst themselves. As a result, devices with the standard dimensional characteristics of 1 m, 1.5 m, 2 m, and 2.5 m are now available in construction stores. Since not all specialists even use the latter, manufacturers do not produce rules longer than 2.5 meters. However, the true master won’t stop the actual collection of models in his collection.

You must become familiar with using a rule of appropriate length if you choose to perform independent apartment repairs and buy one. You can confirm that this isn’t complicated by looking at the following example. The most common application for this tool is to assess the wall’s quality following plastering:

• Take the rule, attach it with an edge to the wall so that its guide is located exactly vertically.
• If the rake adjoins the surface of the wall, then this is a sign that the plaster was applied qualitatively.
• Similarly, it is necessary to check the wall relative to the horizontal plane and diagonally.

If there are any bulges in the wall, you can easily find them during the initial inspection. Since there will be space between the flat bar and the wall’s surface in this instance, the bar will "walk." You can find any surface flaws, like hollows, with this tool. If you angle your view of the plane, you can further confirm their presence. When viewed against the backdrop of a level surface and guide, the gaps will stand out due to their distinct shape. However, even if the check reveals such flaws, you shouldn’t be overly concerned about it.

Today’s building codes permit these kinds of flaws. After all, you can simply remove them when applying putty, leaving the wall with an extremely smooth surface. They will have to take them out if the check reveals that there are bulges.

Verification of the surface with the rule and level

There is some allowance for error in the surface verification process, which applies the rule. It is advised to use the building level simultaneously to reduce such errors. By applying this tool to the rule’s rib, you can concurrently assess the quality of the horizontal and vertical finishes when using it in conjunction with the rule. Naturally, using two tools at once causes the master a lot of inconveniences. Furthermore, not all data obtained are trustworthy.

Thankfully, a rule with a level is now a more practical measuring tool found in stores. It is not like the typical measuring device because measuring cones are already integrated into it. It is as easy to use as the standard rule: all you have to do is affix the guides to the aircraft to view the precise indicators that catch your attention. Often, employing this kind of tool is far more practical than even standard metal rules.

Criterias of choice

The choice of construction rule is one of the primary things that every beginner home master should pay particular attention to. There is nothing difficult here, in theory. All you have to do is be aware of which parameters to focus on.

Profile shape

Prioritize your attention to the product’s profile form that you have purchased. This is crucial because the tool’s strength is directly influenced by this feature. There are two versions of the plastering rules:

• Trapezoidal. It is the rules of this form that can most often be found in construction stores. They allow you to perform many operations, including with high loads on the product.
• H-shaped. A more rare option, which is used mainly for interior decoration and is not designed for surface decoration with heavy compositions.

Ribbly stiffness

High strength is one of the primary requirements that all plaster regulations must meet. As such, consideration of this tool’s design features is required when selecting it. This device’s stability under loads and deformation during operation is traditionally dependent upon its two tubes.

Geometric correctness

It is very difficult to guarantee the high-quality completion of finishing work if the rule is shaped incorrectly. As a result, keep in mind that the work end of the product is perfectly even when examining various models.

The best option for plaster construction rules depends on a number of important considerations. The substance of the rule itself comes first. Choosing a robust material, such as stainless steel, guarantees measurement accuracy and longevity. Because they won’t rust or corrode, stainless steel rules are perfect for outdoor use where they may be subjected to a variety of weather conditions.

The rule’s duration is another important factor to take into account. A guideline of one to two meters in length generally strikes a balance between manageability and versatility for most facade projects. While shorter rules may limit precision over larger areas, longer rules may have a wider reach but may be difficult to maneuver in confined spaces. It is imperative that the length of the rule be aligned with the particular needs of your project.

When selecting a construction rule, accuracy is crucial. Look for rules that have easy-to-read markings for both metric and imperial measurements. Measurements are guaranteed to remain readable over time with laser-etched markings because they are typically more robust than printed ones. This accuracy is essential to getting a uniform and smooth plaster application, which improves the overall finish quality of your facade.

Finally, think about other features that might improve usability. Certain regulations have non-slip grips or anti-glare coatings, which enhance visibility and handling, particularly in gloomy or direct sunlight. These elements can result in a more polished finish by significantly enhancing comfort and productivity during the plastering process.

For external walls to be smooth and level, plaster construction rules must be chosen carefully. This article examines important factors to take into account when choosing a construction rule, including measurement accuracy, material flexibility, and durability. It will go over the various kinds of rules that are available, highlighting the benefits and drawbacks of each, from conventional wooden rules to contemporary metal or plastic ones. To ensure maximum performance and longevity, there will also be a discussion of practical tips for handling and maintaining construction rules. Knowing these elements will enable you to choose wisely for your plastering projects, whether you’re a professional or a do-it-yourself enthusiast, guaranteeing flawless results each and every time.
