Perlite plaster for facade work

Perlite plaster is a flexible and efficient way to improve the strength and visual appeal of the exterior of your house. Heat causes perlite, a naturally occurring volcanic glass, to expand. Its special quality makes it the perfect component of plaster mixtures for external surfaces. Among the many benefits of perlite plaster are its superior thermal and sound insulation qualities, which can promote energy economy and a calmer interior atmosphere.

The remarkable property of perlite plaster is its capacity to control moisture. This feature contributes to maintaining the building’s structural integrity over time by preventing problems like mold growth and moisture on external walls. Furthermore, because perlite is lightweight, it is easier to apply and lessens the overall weight load on the facade, which can be advantageous when building or renovating.

Practically speaking, perlite plaster is renowned for being adaptable and simple to use. Concrete, brick, and metal are just a few of the substrates on which it can be applied, providing flexibility in both design and construction. Whether you’re building a new facade or remodeling an old one, perlite plaster offers a consistent, smooth surface that can be tailored with various hues and textures to fit your style.

Perlite plaster is also known for its ability to withstand fire, which gives the outside of your house an additional degree of security. This feature helps the building comply with insurance and building regulations while also improving the building’s defense against fire hazards. Both builders and homeowners can feel more at ease using perlite plaster in areas that are prone to wildfires or have strict safety regulations.

Advantages	Lightweight, easy to apply, improves thermal insulation, fire-resistant, resists cracking.
Application	Used for exterior facade finishes, suitable for various substrates including concrete and masonry.

Composition, characteristics and properties of plaster with perlite

First, let’s define perlite and discuss why plaster solutions need to contain it.

For exterior or interior work, ready-made plaster mixtures typically include multiple primary components. This is a filler, to start. Most often, fillers are made of porous materials. In our instance, a particular kind of gravel called perlite (also known as perlite sand) is created when the subterranean waters of volcanic glass (also known as obsidian) act as a filler.

Moreover, the astringent base made of cement, lime, or clay in various combinations.

The final ingredients consist of various polymer additives that have the potential to enhance the mixture’s plasticity, water-repellent properties, and oxygen saturation level.

Before we discuss the properties, let us take a moment to consider the mixture’s characteristics.

1. The color of perlite depends on the chemical composition and can be green, black, red-brown, brown and white.
2. Perlit is unique by the presence of constitutional water. This means that the mineral has many pores partially filled with water.

Perlite plaster is made from this particular characteristic of the rock.

We talk about the characteristics of plaster using perlite.

1. Ease of finished coating, which reduces the load on the supporting structures. Therefore, you can equip the foundation less thoroughly by saving money in this way.
2. Thermal insulation. Due to its low thermal conductive indicators, plaster retains heat well.
3. Fire safety. The plaster with the perlite refers to the NG fire hazard class, that is, it does not burn.
4. Environmental friendliness. Passionate effects on nature are approaching zero.
5. Multifunctionality. In addition to its excellent heat -insulating properties, plaster has a high level of sound insulation. Moreover, it can be a decorative coating, a component for leveling surfaces or acting as a final layer.
6. Ease and simplicity of application. Excellent indicators of plasticity of the mixture allow you to get a wonderful surface without ugly flaws.
7. The solution of the solution is not subject to damage to mushroom spores, pathogenic microorganisms and damp.

A cost-effective and adaptable way to improve the appearance and usability of building facades is with perlite plaster. Perlite plaster, which is well-known for being lightweight and having good insulation qualities, increases energy efficiency and offers long-lasting defense against moisture and weathering. Because of its simplicity of use, it can be applied to a wide range of architectural designs, providing both homeowners and architects with a useful option that blends aesthetic appeal with useful features. This article examines the benefits of using perlite plaster for facade applications, emphasizing how it can be used to create building exteriors that are both aesthetically pleasing and sustainable.

The pros and cons of this mixture for facades

Excellent thermal insulation is without a doubt the primary benefit of the plaster mix with perlite, which is why more and more people are choosing it. It is safe to refer to such plaster as "warm."

Now that we have compiled the characteristics of perlite plaster, we can quickly go over the remaining benefits:

1. Noise insulation.
2. Safety, both fire and ecological.
3. Biological stability.
4. Multifunctionality.
5. Simplicity at work.
6. Resistance to external influences.
7. Unattractiveness for rodents due to the lack of organic substances.

Types of perlite plaster

Keeping in mind what was said about the astringent foundations, we can determine that perlite can be made of clay, cement, lime, or mixtures like cement and lime. Filler made of perlite adheres well to all kinds of binding foundation.

Plaster with perlite based on cement

For facade work on houses in high humidity, a cement and perlite mixture works well because the cement produces a good waterproof coating. Plastering can be done manually or with the aid of a specialized tool and pre-made mixtures. The plaster with perlite exhibits its heat-insulating properties after the processed surface dries completely, which typically takes two months. The acquisition of maximum strength coatings takes one month.

Plaster with perlite based on gypsum

Given that gypsum is water-phobic, mixtures of perlite containing the highest concentration of gypsum are frequently utilized for interior building decoration. Because these mixtures can have very short lives, working with them requires specific skills. When manufacturing a composition using house gypsum, numerous issues may arise because the composition’s specific gravity must be lowered to 500 kg/m3, even though a composition with a minimum specific weight of 800 kg/m3 is achieved.

It’s simpler to buy gypsum-based perlite plaster. Professionals will create and test the compositions. The completed compositions also contain extras that contribute to an extended way of living and make styling easier.

Plaster with perlite based on lime solution

The production of this kind of solution requires a high-grade hazardous lime. All things considered, the perlite mixture based on lime solution is bactericidal and environmentally friendly, despite its mild strength. By adding cement to the mixture, the issue of its strength is resolved.

How to prepare a mixture with your own hands

Even though stores are filled with ready-made dry solutions, you can prepare perlite plaster by yourself. Think about the ingredients that are required as well as the manufacturing process.

Cement, perlite, aqueous solution, and additives made of polymer compounds are needed for manufacturing. Usually, one part cement, four parts perlite, additives added in one tenth, and water added until the required consistency is reached are used.

Note: Perlite needs to be moistened before mixing, as it won’t dissolve with the other ingredients until it has enough water.

Both manually (with a drill or specialized construction mixer) and in the mixer’s solution are options for kneading.

Fill the chosen container halfway with water, then top it off with polymer additives. Combine perlite and cement; then, slowly add water to the mixture until a thick, plastic mass is reached. They let the mixture sit for fifteen minutes so that the flavors could infuse, and then they thoroughly mixed everything.

The independent mixture will be less expensive than the purchased one if a large surface is needed. For instance, a ton of cement can be purchased for between 3,000 and 4000 rubles. A bag of bastard lime costs approximately 150 rubles, while a cubic meter of perlite will set you back two thousand rubles.

Technology for applying plaster with perlite for external walls

The working principle is the same as it is for other solutions. Plaster with perlite can be applied mechanically or manually. If you choose to handle the facade work yourself, be aware that the completed solution is applied to the passageway in an approximate three-centimeter thickness. You have to wait between them for the duration needed for the layer to dry. It is best to wait at least four hours, but ideally a day.

The mixture is aligned without being pressed firmly with the spatula, as this may cause the mixture’s air content to decrease and cause it to hang and crack.

The following are the requirements for applying:

1. Air temperature not lower than 5 and not higher than 30 degrees Celsius.
2. Humidity is required to make up less than 80%.
3. The base should be protected from precipitation and direct sunlight.
4. The base should be moistened before applying the solution if from 30 degrees Celsius.

Tool

When working with different compositions, the toolkit doesn’t really change that much.

Typically, they consist of the following: paint tape, ladders, beacons, mixing containers, grater, spatulas, and kelm. For your own safety, you should wear gloves, safety glasses, and a respirator.

Preparation of walls before applying

If you have ever applied plaster, or cement, for example, you are familiar with the general algorithm of action, which is quite similar.

The walls are first cleared of outdated applications. To improve the coupling, you must lay out and deepen the masonry seams if you are working with a brick coating. Patch up big cracks and seams. Damage foci containing mold, mushrooms, or bacteria are cleaned with a mixture of biocide.

Oil stains get cleaner, and the layer of rust is removed. Priming twice is required to improve the clutch and stop the solution from becoming dehydrated due to moisture absorbing into the wall’s concrete material. If you apply a thick layer of composition, the base must dry and set the beacons.

Application of plaster

Plaster application requires the use of a plaster spatula. After application, the surface is aligned while keeping in mind that it cannot be pressed. You can use a plaster rule or grater for alignment. Typically, 0.5 to 5 centimeters of thickness are applied to each layer. After that, the rule is applied and the plaster is cut as soon as it grabs. Using a sponge dipped in water, the surface can be briefly examined after two hours. The coating starts to take on a glossy appearance when it is wiped. After two days, color dry coating is accepted.

Common errors when working with perlite plaster for the facade

Think about the common mistakes and how to prevent them.

• Error: high speed of kneading the required mixture

Solution: It’s important to keep an eye on the mixer’s or the solution’s rotational speed when kneading the mixture; it shouldn’t exceed 600 revolutions per minute.

• Error: insufficient preparation of the base

Solution: The degree of adhesion of the coating is contingent upon the state of the plastered surfaces, their subsequent appearance, and their ultimate quality and durability.

• Error: too liquid solution

Solution: Mix the liquid a little after Perlit starts to give it, controlling the consistency. Don’t pour out the full recommended volume at once.

A versatile option for improving your home’s facade is perlite plaster. Because of its volcanic glass composition, which is lightweight, it is simple to apply and, once set, durable. This material has practical advantages in addition to enhancing the exterior’s aesthetic appeal.
