Baritic plaster

A specialty material that is becoming more and more popular in contemporary building and renovation projects is baritic plaster, sometimes referred to as barite plaster. In contrast to conventional plaster mixtures, which frequently contain lime or gypsum, baritic plaster has barite as a primary component. The plaster is enhanced by the distinct qualities of barite, a mineral that is widely available in nature and is especially well-suited for certain uses in building facades.

Baritic plaster is distinguished by its remarkable weight and density. It is perfect for improving the acoustic and thermal insulation of buildings because of this feature. Barite’s density enables the plaster to function as a sound-transmission barrier, thereby mitigating external noise pollution. Furthermore, because of its high density, which lowers heat loss through walls, it improves thermal insulation and helps to maintain comfortable indoor temperatures.

The remarkable resistance of baritic plaster to environmental factors is another noteworthy benefit. Structures with baritic plaster have better weather resistance and durability. Because of its durability, it’s especially good for outdoor applications where traditional plaster finishes can eventually deteriorate from exposure to moisture, UV light, and temperature changes.

Baritic plaster is not only useful, but it is also aesthetically pleasing. It can be altered to have a variety of finishes and textures, from textured and rugged to sleek and smooth. This adaptability enhances both traditional and modern architectural styles by enabling designers and architects to create a broad variety of visual effects.

In conclusion, baritic plaster is a modern way to improve the functionality and aesthetics of building facades. Because of its special makeup and qualities, it is the material of choice for applications where flexibility in terms of appearance, insulation, and longevity are critical.

Dry mixtures

Different types of baritic plaster are currently produced for industrial companies; these types vary in composition, price, and physical properties.

Requirements of sanitary authorities to apply baritic plaster

Alternative materials for protection must adhere to SanPin 2.6.1.1192–03. The maximum power of rays in laboratories or industrial settings, as well as the specifications of the X-ray design documentation, are taken into consideration when calculating thickness.

The approximate amount of baritic plaster consumed and the protective parameters’ ratio to the thickness of lead plates

The thickness of the lead shield	Approximate expense per square meter of area	The thickness of the barite plaster
1 mm	45–47 kg	10–11 mm
2 mm	84–86 kg	20–21 mm
3 mm	148-150 kg	29-30 mm
4 mm	205–210 kg	35–37 mm

The thickness of the lead plates should be used to calculate the required thickness of the baritic plaster. The design documentation specifies the lead parameters, which are contingent on the X-ray radiation capacity. The standards for guaranteeing the safety of the staff and patients at the clinic are set forth by sanitary norms and regulations. Any changes that are made to the equipment’s design capacity or the degree of protection it offers must be approved by sanitary organizations beforehand.

Taking baritic plaster ingestion

Vital. The information provided in the table regarding the baritic plaster’s thickness is illustrative and subject to variation based on the particular material and its characteristics.

Plaster screening indicators ought to be verified through testing procedures carried out in compliance with GOST 12.4.217-2001. Test results cannot be used to determine the protective layer thickness for other materials; instead, each one must undergo required individual verification. Take the preparation process for certain kinds of baritic plasters, for instance.

Procedure for the preparation of the mixture baritabot concrete M200

The mixture is made up of two parts: a polymer and a hardener. The dry baritaton powder has a mass of 24 kg and a volume of 6 liters. Make sure you wear a respirator when cooking. In a concrete or solution mixer, the ingredients are well combined until a uniform mixture is achieved. Adding water yields the required consistency for the intended use. More liquid mixture is needed for plastering; more viscous mixture is needed for concrete flooring or wall filling.

Vital. After 45 minutes of using the completed mixture, irreversible polymerization processes start. Determine the amount while keeping labor productivity and material costs in mind.

The final blend can be applied to:

• manufacturing piece blocks of various sizes. Interior partitions are being built from the blocks, protective fences for X-ray apparates of various sizes and radiation power are built;
• applying a protective layer by formwork. Used in rooms with high radiation indicators. Accelerate the process, instead of several stages of the plaster of the work, you can perform at one time;
• floors filling as a protective coating. Physical indicators of strength make it possible to use any materials for the finishing flooring;
• plastering walls and ceilings. It can be both independent protection for small doses of radiation, or to be used as an addition to zinc slabs.

The protective filling or plaster is very thick. Reinforcement of supporting walls is necessary to increase strength and dependability. How is it carried out?

Purchase a metal grid for reinforcement. The thickness of the protective layer of baritic mixtures is taken into consideration when choosing the diameter of the wire and the size of the cells.

Metal mesh for reinforcement

Step 2: Insert the dowel into the bearing wall in a checkerboard pattern at intervals of roughly 50 cm. The dowel should be at least three centimeters long in the wall, and its height should be half the thickness of the filling or plaster. Choose the dowels’ diameter and length by keeping these factors in mind.

The dowel is fastened to the wall.

Step 3: Use copper or aluminum wire to secure a metal reinforcing stack to the dowels. Verify its location and prevent bloating.

We secure the dowels to the reinforcing mesh.

Once everything is ready, you can begin filling or plastering. We’ll explain how to do it below.

It is not appropriate to independently prepare a barite plaster from the ingredients. The shielding indicators are unknown since the percentage of the elements cannot be precisely controlled. To receive a certificate of conformance, state laboratories should receive verification reports from each batch that was manufactured independently. It is advised to buy ready-made compositions that specify the precise amount of fillers and shielding properties.

Magnesian fillers or cement can be used to create baritic plasters. Physical and functional properties of materials vary significantly.

Operational characteristics	With magnesian filler	With cement filler
Approximate material consumption per 1 m2 of area with a plaster thickness 10 mm	14–20 kg	21–24 kg
Approximate unproductive losses	Absent	Up to 20%
The maximum possible thickness	Up to 40 mm	Up to 60 mm
Features of application technology	For drying each layer requires at least 7 days	Drying out of about 24 hours
Crossing resistance	Average	High
The thickness of the layer applied at a time	3-30 mm	7–12 mm

Plastic plaster plastering technology

Compared to standard plaster, the material is significantly more costly due to its cement-sand composition. This feature lays out specific guidelines for surface preparation.

Step 1: Examine the wall’s surface. If there are any outdated coatings, they ought to be taken off. Big bumps and fissures are required. The amount of costly material used decreases with the smoothness of the baritical plaster layer.

Cleaning and preparing the wall in advance of plastering

Step 2: Hold off until the wall dries fully. Take off its measurements, and based on the layer’s thickness, estimate how much plaster is needed.

Measure the space.

Vital. The design documentation of the location with the x-ray equipment, the sanitary standards requirements, and the filming regulations must all be considered during the computations.

Step 3: Make sure to apply primer to the wall’s surface. In two perpendicular directions, make the coating. The truth is that you must take all necessary precautions to improve adhesion because the plaster has a minimum thickness of about 20 mm and is heavy.

The wall is primed by us.

Step 4: Create beacons. It is best to make them out of baritic plaster instead of metal; regulatory acts specify this. How can plaster be used to make beacons?

1. Clean the wall of dust, remove all building garbage from the flooring.
2. Draw on the wall vertical lines in level. The distance between them should be 25-30 cm less than the length of the rule.
3. Prepare a small portion of baritic plaster, thoroughly mix the mixture until the lumps are completely removed.
4. Wet the vertical line with a spray gun, throw a baritic solution on it. Throw it from the bottom up into the line, the width of the strips is approximately 5-8 cm
   thickness of at least 2 cm.

How beacons are installed

Step 5: Start plastering the wall once the beacons have solidified. Between the two nearby beacons, toss the solution starting at the bottom. The thickness. The truth is that two coats of plaster will need to be applied, one layer cannot be two centimeters thick, and large cracks will open up as the plaster dries. Skilled artisans can start with smaller volumes and quickly toss the mass up to a height of approximately half a meter.

Step 6: Align the surface of the mass with the rule until it freezes. Move the tool continuously to the left or right by pulling it up from the bottom. Return the solution that has accumulated on the rule to the container and stir again. The first layer of plaster should not have an even surface; the more voids and tubercles there are, the longer the second layer will last. If the thickness exceeds two centimeters, disregard this rule.

The guideline and the wall are in line.

Step 7: After leveling and sketching the first lower portion of the wall, place a barite plaster above the same beacons. Thus, all the way to the ceiling.

Put on some barite plaster.

Step 8: Completed the area in front of the first lighthouse; move on to the next. We guarantee that real-world experience will soon surface, making work much easier. There will be no mass fall off the wall, and all directions of spray will stop. You’ll be aware of how many masses to scoop with a trowel, how hard to toss it, and which ways to move your hand. Knowledge is a powerful tool.

The second or third day is when the next layer of plaster can be applied. The temperature, humidity level in the air, and the room’s ventilation all affect the terms used.

The second layer of baritic plaster’s surface ought to be precisely in the same plane as the beacons. If there are any recesses, throw the solution at them again. The grouting of the surface is a crucial aspect that requires skill.

Only then should the grout be started; the code mass will have a consistency similar to soft butter. Start later, and the surface will only get worse; create a recess. If later, a thin layer of solution may exfoliate and alignment will be challenging. It is acceptable to slightly moisten the surface while grouting. After soaking a special brush in a bucket of water, spritz the cleaned surface.

Use a tool only in circular motions. Add a small amount of mass to the nooks and crannies. When working, the grout’s edge should always be flat on the surface, and the mass should be rubbed in the center. Lack of experience: after working in a small area initially, the skill shows up and grows concurrently with grouting areas.

A method for massaging the plaster

The grout should only be slightly more compressed after significant irregularities have been fixed. Initially, the pressing force should be leveled as little as possible, and all work should be done carefully and slowly. Recall that it is far simpler to ruin the surface than to level it again.

Finishing wall decoration

Baritic plaster poses a health risk because the chemical element’s microparticles can enter the lungs and cause a number of illnesses. Plaster must be protected after it has completely dried in order to avoid such circumstances. Painting the walls with oil paints is the simplest and least expensive method. However, you can create the skin of panels using different materials or apply wallpaper over it. The particular finishing technique ought to consider the aspects of the premises’ operation.

The technology of pouring baritic plaster with a thick layer

Making the wall filling beneath the formwork is quicker and more dependable if the plaster layer is thicker than 2 cm. As we’ve already indicated, the metal reinforcing mesh needs to be fixed in this situation.

Vital. The thickness of the poured layer should match the length of dowels that are exposed above the surface and are used to secure the mesh. How is a formwork made? Examine two alternatives for production: using special moisture-resistant glued plywood or trimming boards.

Writing from boards

Since the filling is thin, you can use cut boards that are about 20 mm thick.

Step 1: Take away the wall’s dimensions. It is preferable to construct two shields from the boards if the length is longer than three meters since this reduces the chance of deflection. However, a particular choice is made immediately, considering the perimeter of the fortified wall. The shields have a height of no more than one meter and a length of roughly 1.5 meters.

Wall of a structure with a strengthened net

Step 2: Book boards are fastened to 30 x 50 mm wooden rails by pressing them as firmly as possible against one another. There is only one meter separating each vertical rail.

Step 3: Turn the shield so that the front side is facing up and examine where the boards are. Eliminate any drops in height that you find.

Step 4: Place the formwork against the wall so that its hats on the self-tapping screws rest on them. Verify the verticality level and make the necessary corrections.

Step 5: Use corner supports to secure the formwork.

Formwork made of wall-mounted boards

Continually level, pour the barite plaster on top. Use an electric vibrator, if available, to extract air from the mass. If not, hammer the formwork repeatedly until the mass stops settling.

Step 6: Remove the formwork and install it on the wall above in the same manner after the mass has frozen. It won’t harden for at least a week, so don’t rush to put up strong defenses. Deep cracks or discharge are highly likely if the mass has not strengthened.

There is always a space between the wall and the ceiling, which requires multiple trowel applications to plaster.

Eliminate the irregularities once the work is finished. They can be removed or wiped, depending on their size. The finish determines how level the wall’s plane will be in the end. The wall should be as high-quality as possible before painting or applying wallpaper because alignment is impossible beneath the upholstery of walls with different panels.

The work will proceed more quickly and the wall’s plane will be more accurately constructed if waterproof plywood shields are available for the formwork.

Remember that you will undoubtedly need to create a concrete screed on top of the barite layer because the material’s strength is insufficient for heavy X-ray attitudes.

It is necessary to lay a concrete base before beginning any work; typically, this consists of a reinforced concrete floor slab. The solution is applied in accordance with the beacons, and a long, even wooden rail that is at least 5 centimeters wide is used to level the surface. The only requirement is that you wear a respirator while preparing the solution.

Purrender of the ceiling

If you lack experience, avoid taking on this kind of work.

Step 1: Dust and clean the concrete plate. Large fissures and irregularities found; fill them in. It is a fact that the baritic plaster thickness needs to be constant throughout the region, and this can’t be accomplished unevenly.

Step 2: Apply a primer to the surface and moisten it twice in transverse directions.

Sensible guidance. Applying cement milk prior to plastering a ceiling will greatly improve the baritic plaster’s coefficient of adhesion with a concrete slab. This is accomplished by dissolving cement in water in a small container until it has the consistency of liquid sour cream. Using a bucket, the solution must be thrown onto the ceiling; once it solidifies, tiny "icicles" will hang from the ceiling. They greatly expand the baritic solution’s surface area in contact with the base. Although the method is very old, it always works without any issues.

Step 3: Attach the ceiling-mounted beacons. Use metal thin rails that are not taken from the mass and fasten them with dowels.

Furthermore, the work is exactly the same as plastering the walls—plastering is just obviously far more difficult. Use goggles to shield your eyes from a baritic mixture.

Baritic plaster, sometimes referred to as heavy plaster, barite plaster, or just plaster, is a specialty material used in renovation and building projects because of its special qualities and uses in building facades. This plaster, which is mostly made of barite aggregate combined with binders like cement or lime, has great density and durability. Because of its composition, it is perfect for environments where a high level of impact, weathering, and fire resistance is required.
