Marble plaster

Marble plaster, sometimes referred to as polished plaster or Venetian plaster, is an opulent decorative finish that is becoming more and more common in contemporary interior and architectural design. Compared to conventional stone surfaces, this material offers greater application flexibility and a more realistic appearance similar to that of natural marble.

Marble plaster, made from a mixture of slaked lime, marble dust, and other minerals, is well known for its glossy, smooth finish that gives walls and facades a sense of depth and elegance. It can be customized to fit different design schemes because it can be tinted to a wide range of colors.

The ability of marble plaster to produce a smooth, continuous surface is one of its unique qualities. It can produce a polished appearance that beautifully reflects light when applied correctly by skilled craftsmen, improving the overall aesthetic of any exterior or interior space.

Marble plaster is not just aesthetically pleasing; it also has useful properties. Because of its strength and resilience to cracking, it can be used in both commercial and residential settings. Its composition also permits it to breathe, which aids in moisture regulation and the preservation of a cozy interior atmosphere.

Composition and characteristics

The filler, which is ground marble or granite with varying granularities, is what makes up the majority of the plaster. Although the filler granules have a wide range of natural shades, they are frequently tinted using specialized technology to enhance the coating’s decorative appeal. Although there are marble plasters made of minerals, most manufacturers use acrylic resins as a binder. Differentiating between transparent and translucent acrylic compositions and colored and white mineral compositions is not difficult.

The plaster’s hues are marble.

Apart from the binder and filler, the plaster’s composition also includes antibacterial agents, solvent, water-repellent additives, and different modifiers to improve the coating’s plasticity, adhesion, color resistance, and other attributes. In addition, the solution might include mother-of-pearl or sparkles, which would give the plaster a more intriguing texture.

The plaster is classified as fine-grained (grain thickness to 0.5 mm), medium-grained (1-3 mm), or coarse-grained (3-5 mm) based on the size of the granules. The texture of the coating varies depending on the granule size. The filler faction influences the material’s consumption as well:

• small – from 1.5 to 2 kg/m2;
• average – from 2.5 to 3 kg/m2;
• large – from 3 to 5 kg/m2.

At least 1.5 times the size of the filler grain should be present in the layer of solution applied. The coating thickness varies by 5 to 30 mm on average. The plaster takes roughly a day to dry, although this greatly depends on the air’s temperature and humidity as well as the layer’s composition and thickness.

There are several noteworthy benefits to marble plaster.

• simplicity of finishing – the composition is applied in one layer on the prepared base and is smoothed out by a grater. No need to perfectly align the surface, form a relief, polish the finishing layer, as the Venetian plaster requires this;
• strength – after drying, the coating becomes incredibly resistant to washing, mechanical exposure, moisture and temperature changes;
• Durability – a qualitatively executed decoration lasts on the facade for years, practically without losing the original appearance, without fragmenting or crumbling;
• Decorative – marble plaster is distinguished by a rich color palette, which allows you to create colored patterns on the walls, ornaments and art panels. Compounds with multi-colored crumbs form an interesting mosaic coating, and even monophonic plaster looks very attractive due to polished granules that shimmer under the sun"s rays;
• Ease of care – to wash off dust and dirt from the coating, it is enough to rinse it with water from the hose, and the plaque and soot from car exhausts are without much difficulty washed by a brush and soapy solution;
• Environmental friendliness – there are no toxic and chemically aggressive substances in the plaster, so it is completely safe in environmental terms.

Marble plaster costs significantly more than textured plaster, but it is less expensive than Venetian. You can apply it on your own and save money by not hiring a professional because it doesn’t require any specific skills. Regarding the drawbacks, the main one would be the coating’s substantial weight as a result of the stone filler.

The plaster is marble

With its classic elegance and adaptability, marble plaster provides homeowners with an opulent way to accentuate their facades. The advantages of marble plaster are discussed in this article, including how long-lasting and weather-resistant it is as well as how well it can replicate the appearance of real marble at a much lower cost. Understanding the application, upkeep, and aesthetic possibilities of marble plaster can help you make well-informed decisions to improve the external appeal of your home, whether you’re thinking about renovating or installing a new facade.

The scope of application

Marble plasters are excellent for decorating surfaces that need more moisture resistance, such as basements, exterior walls of homes, saunas, swimming pools, and bathrooms.

Marble-like plaster

Such compositions are also a perfect way to decorate curved surfaces, such as columns, niches, curving protrusions, and biases, because of their easy application. They are employed to complete apertures, minor architectural elements, and both residential and non-residential spaces.

Preparatory stage

Plaster requires an even, strong, and dry base; otherwise, the coating will not last very long.

The surface needs to be clean, dry, and leveled beforehand.

As a result, in order to begin painting the wall, the surface must be thoroughly inspected and cleaned with a brush to remove dust and debris. You should thoroughly clean everything down to a solid foundation if there are any areas of crumbling plaster, swelling, or exfoliation. For this, use a bell with a nozzle or a metal brush. Since the voids are most frequently created at the panting seams, pay extra attention to cleaning them.

After being stripped, areas impacted by mold or fungus are treated with antiseptic compositions or agents containing chlorine. In order to prevent them from showing up on the surface of the fresh coating, valves on the walls must also be removed. There are specific cleaners for this that you can purchase from any building supply store.

A typical cement mortar is made by mixing one part cement with three to four parts sand to seal indentations, chips, and cracks. Before sealing, cracks need to be broken, dusty, and reinforced with fiberglass tape after a solution has been added. Next, check the wall planes with a level or rule to see if the plaster needs to be aligned.

Suggestions. The black leveling layer can be decorated with coarse-grained decorative mixtures. The base layer’s fine- and medium-grained plasters are applied with a finish that eventually gives way to grinding after drying. The base should be more even the thinner the coating.

Once the plaster has dried completely, you must wait to apply soil to the walls. It is advised to select the covering soil (such as Astar Bayramix, Ceresit CT 16) and tint it to the color of marble plaster before applying it to the wall to prevent the base from showing through the finish. This is relevant to acrylic compositions because mineral plasters can be made with a standard primer and quartz filler.

Adding soil to the plaster’s tone

The earth dries in 12 hours.

After the surface is ready, you can work with the tools and materials. You’ll need clean, room-temperature water, a stainless steel trowel, a grater, and a drill with a mixer nozzle for the task. Since some of the plaster crumbles during application and stays on the walls of the container and the tools, it is best to purchase the plaster with a margin of 7–10% of the total volume.

Suggestions. Purchase plastering from a single manufacturer for the facade’s basic decoration (preferably from a single batch of manufacture). When applied to the wall, the compositions of various brands can exhibit notable variations in color and texture, even though they may appear to be very similar visually.

Manual plastering

While plaster may be ready to be applied right away, it is usually necessary to dilute the solution with water or solvent because it is too thick. The manufacturer is required to list this information on the label, along with the corresponding proportions. For instance, up to 1.5 liters of water are needed for 25 kg of Bayramix plaster and only 125 ml are needed for 20 kg of the Ceresit mixture. Before beginning the finish, carefully read the instructions to avoid ruining the pricey material.

Step 1: Open the solution container and thoroughly mix using a mixer. Use water to adjust to the appropriate consistency if needed.

Step 2: Holding the trowel at a 60-degree angle, they type a small amount of solution on it and apply it to the surface. The mixture is applied in a single direction in a uniform layer, rubbing firmly at the base. They work on the walls in squares so as not to dry out the plaster layer’s edges.

Decorative plaster application

Keeping an eye on the same layer thickness is crucial.

Use tiny amounts of the mixture.

Suggestions. If work must be stopped, masking tape should be adhered to the processed area’s edge, the solution should be applied and allowed to settle, and the tape and leftover plaster mixture should be removed.

Step 3: They start grouting the surface after the plaster starts to take hold, which takes 20 to 30 minutes. Use a stainless steel grater to accomplish this. Tightly pressing against the wall, the tool moves in a circular motion to smooth the coating while attempting to apply constant pressure. It is not necessary to process one site for an extended period of time or to crush too much.

After preparing the surface as previously mentioned, the plaster solution is added to the container, the air is pumped out, and the application process is started. A working pressure of 6-7 atmospheres is recommended. To ensure that the solution covers the base uniformly, the device’s nozzle is slowly lowered from top to bottom while being held no closer than half a meter from the surface.

Creating a drawing

Plastering in two or three colors is common for adding more decorative elements to the facade during decoration, such as stripes, curling inserts, and other ornaments. While there are some technological differences in this instance, the solution itself is not particularly complex.

The following tools are needed to create colored inserts with straight contours: masking tape, long rail, level, and marker. Make a sketch of the facade first, then decide on the size and placement of the color sites. Next, mark the wall, making sure to clearly define each contour. Place the adhesive strip around the edges of the areas that will be completed first. Next, carefully apply the desired colored plaster to the prepared surface, making sure not to extend past the tape.

In order to avoid staining the treated areas with a solution, fresh stripes are adhered along their edges after the plaster has been grouted. The tape is then removed. The remaining area was plastered, grout was applied, and painting tape was taken off. As a result, you can create inserts in any quantity and size; the only requirements are correct placement and thoughtful color selection.

The painting tape can be taken off once the plaster has been aligned.

Remove the tape gently, and if needed, adjust the joint.

Painting tape is used to make drawings of any kind.

Marble plaster gives external facades an opulent and refined finish that elevates modern architecture with timelessness. Usually made of a mixture of marble dust and lime putty, it imitates the look of real marble with a smooth, resilient surface.

The adaptability of marble plaster is one of its main draws. It can be used in a variety of colors and textures to give homeowners and designers a range of visual effects, from polished and slick to rustic and textured. It is a well-liked option for both traditional and modern building designs due to its adaptability.

Marble plaster is prized for more than just its aesthetic qualities. It offers superior weather resistance, shielding the structure from damaging weather conditions and preserving its aesthetic appeal over time. Because the material is breathable, moisture cannot accumulate, protecting the facade’s structural integrity.

In conclusion, marble plaster sticks out as a high-end option for improving the outside of both residential and commercial structures. Because of its unique combination of aesthetic appeal, longevity, and practical benefits, it’s the go-to choice for people looking to improve the facade’s look without sacrificing performance or protection over time.
