Advantages and disadvantages

With mosaic plaster, designers can realize even the most audacious interior concepts. When selecting a finishing coating, one must consider the various benefits and drawbacks of this type of finishing.

• color fastness to UV rays;
• weather resistance;
• can be applied to any base;
• impact resistance;
• high vapor permeability – the surface breathes;
• range of colors and fillers.

• high cost;
• demanding knowledge of technological processes.

One more explanation for mosaic plaster’s conditional disadvantage is its limited use in living rooms. This kind of wall will feel chilly to the touch, which customers may not always find appealing.

The durable and eye-catching decorative finish known as mosaic plaster is made by combining colored granules with a clear binder. It has outstanding resistance to moisture, impact, and UV rays, making it perfect for usage both indoors and outdoors. This adaptable plaster is ideal for enhancing accent walls, facades, and high-traffic areas because it can be applied to a variety of surfaces. It is a popular option for modern interiors and exteriors because of its ease of maintenance and broad spectrum of colors and textures, which enable creative designs that are both useful and aesthetically pleasing.

Application area

Decorative mosaic plaster is used to plaster both interior and external surfaces, despite its current drawbacks:

• arches, niches and columns in rooms;
• walls in rooms with high humidity – baths, saunas, bathrooms;
• partial decoration of walls inside rooms;
• of building facades;
• decorative and capital partitions.

For the basement, mosaic plaster is appropriate. The mixture can be used on the outside and inside of contemporary buildings due to the material’s resistance to moisture and temperature changes.

Types and characteristics

Mosaic plaster is not categorized in a single way; instead, builders typically classify it based on the size of the stone chips and the type of primary filler. The goal of the composition also varies based on the fractions’ sizes (in millimeters):

• With a fine texture – up to 0.8;
• Small – 0.9 – 1.2;
• Medium – 1.3 – 1.6;
• Large – 1.7 – 2.

Decorative mosaic plaster with a fraction of up to 3 mm is used for the base’s final finishing. Different fractions can be mixed together when plastering indoor walls to give the appearance of a volumetric pattern. As for the filler, it can be marble or quartz; for mosaic works, "Ceresit ct-77" is an acrylic decorative plaster.

Another crucial factor is the kind of binder. They fit into the following groups in this instance.

1. Mineral. Cement is used, less often – lime. Used for interior work.
2. Silicone. Also used for plastering interior walls and partitions.
3. Acrylic. Various polymers are the binder for stone chips. Putties (Compositions) for universal use, the most famous is "Ceresit CT 77" polymer mosaic plaster.
4. Silicate. Used by professionals. The composition includes potassium glass, which quickly hardens when interacting with water.

Since finishing masters use mosaic plaster "Ceresit" (Ceresit) the most, we’ll go into more detail about its use.

Preparation for work

It is necessary to prime the wall before plastering it. It is advised to use the primer "Ceresit CT 16" for these objectives. The primary requirement is that the impregnating solution and mosaic plaster have to be the same color.

When priming, use a roller or brush to apply the solution to the wall after making sure the tool and dilution container are clean. This also holds true for applying mosaic plaster to facades.

Use cement mortar to fill in any gaps and crevices, then reinforce with reinforcing mesh.

Plastering tools

As the primed wall dries, get the tools ready. Depending on the tasks at hand, finishers can choose from a variety of options, but typically they use:

• trowels;
• brushes of different sizes;
• spatulas – rubber and stainless steel;
• graters, half-graters, rules;
• stencils or textured rollers, depending on the desired pattern.

Verify if the instrument is clean. There shouldn’t be any chips, scratches, or curved surfaces on spatulas or floats.

Application technology

Using particular technologies, mosaic plaster is applied while accounting for the desired outcome, surface type, and grain diameter.

Use the steps listed below to decorate a flat wall without creating an ornament.

1. Check the entire surface for cracks.
2. Pour the dry mixture into the prepared bucket, add water in the required proportion, mix until smooth.
3. Apply the composition from one corner to another, preventing the solution from drying.
4. Work with smooth movements, with a little pressure on the spatula or float.
5. Make sure that the thickness of the applied layer is equal to the size of the crumb fraction.

Applying mosaic plaster in two layers is preferable. Once the first has fully dried, the second is applied.

In this instance, gaps can be avoided and a consistent surface in terms of color and texture can be achieved.

A special material that combines toughness and aesthetic appeal is mosaic plaster. Because of its adaptability, it can be used in both indoor and outdoor settings and comes in a variety of color and texture combinations. Mosaic plaster offers a multitude of design options, whether your goal is to add a bold accent or a refined, polished finish.

Although the application process is simple, it does need some planning and close attention to detail. You can get a long-lasting, high-quality finish by using the suggested methods and making sure the surface is clean and well-prepared. The plaster will remain in good condition for many years with regular upkeep, such as periodic cleaning.

All things considered, mosaic plaster is a great option if you’re looking for both beauty and functionality.
