Composition of the plaster, its advantages and disadvantages

Acrylic copolymers and stone chips are combined to create mosaic plaster. As a filler, crushed natural stone chips such as quartz, granite, marble, malachite, and lapis lazuli are utilized. Pigments used in coloring give the composition its shade. A binder, modifiers, etc. are also included in the list of components.

Mosaic coating is versatile and can be used to decorate spaces in a variety of styles. It can blend multiple hues and textures together. It is advised to use fine-grained crumbs for interior work and coarse-grained material for facade work. The combination is utilized in suburban construction as well as public and residential building design.

• long shelf life;
• resistance to ultraviolet radiation, climatic precipitation, mechanical damage;

Types of mosaic decorative plaster

• size of granules;
• type of raw material;
• purpose (for facade, interior decoration or basement decoration, universal compositions);
• texture;
• type of binders, etc.d.

Size of stone grains

The size of the stone chips can range from 0.8 to 3 mm; this depends on the properties of the rock and the plaster material’s intended use.

• fine-textured – 0.5-0.8 mm;
• small-textured – 0.8-1.2 mm;
• medium-grained – 1.2-1.5 mm;
• coarse-grained – 1.5-3 mm.

Type of raw material

Decorative mosaic plaster is separated into the following subtypes based on the type of natural stone:

• granite;
• malachite;
• marble;
• lapis lazuli;
• quartz.

The use of onyx, travertine, etc. as filler is also common. Combining various stone varieties (marble and malachite, granite and marble fragments, etc.) results in unique compositions.

Neutral-colored stone chips can be further tinted if the stone has a rich shade.

Type of binder

• mineral;
• acrylic;
• silicate;
• silicone;
• mixed.

The filling of mineral plaster mixtures varies. The list of reasonably priced options includes items made with cement, lime, or gypsum powder. The products have restricted usage conditions, but you can still adjust the coating strength. Cement is only used for facades; plasters made of gypsum and lime are used for interior finishing projects.

One kind of plaster known for its elasticity and decorative quality is acrylic. It is created as surface compositions that are ready for treatment. Binders made of acrylic resin are employed.

Silicone resins serve as the foundation for silicone finishing mixtures. This type of plaster can be used for interior finishing projects. The elastic material is used to create unique, textured compositions. Because of the makeup of steam therapy, you can keep the room’s microclimate steady.

The effect of mosaics can be replicated on a surface with silicone composition; the technique is characterized by the use of tiny mica, mother of pearl, etc. D. Dense coatings of small particles. Experts advise covering the surface with a transparent varnish to protect small portions.

Silicate plaster is different in that it solidifies quickly, contains potassium glass, and is meant to be used with professional finishes. The decorative coating has a 20-year shelf life. It is advised to apply the material to gas silicate blocks, gas and concrete bases, etc. because of its good vapor permeability. Water is used to dilute the powder.

Fillers, modifiers, and plasticizers made of silicone and silicate are found in mixed compositions. You can use finishing mixtures to come up with unique interior design ideas.

Acrylic mosaic plaster: why it is chosen

Manufacturers create acrylic mosaic plaster either as dry mixtures or solutions. The mixture is appropriate for processing concrete, foam, and gas bases as well as brickwork, plasterboard slabs, and real or artificial stone. Processing of surfaces plastered with lime mortar or sand-cement is permitted.

• resistance to temperature changes;
• under the influence of ultraviolet radiation, the material does not fade, the rich tone is preserved for decades;
• high moisture resistance provides protection of the base from high humidity;
• vapor permeability allows you to maintain a stable microclimate in the room;
• resistance to mechanical damage, chemical detergents, precipitation (facade plaster);
• no shrinkage during application;
• easy to care for the finishing material.

Required tools

• spatulas;
• wide brushes;
• stainless steel float;
• trowel;
• masking tape;
• construction mixer;
• clean rags;
• containers for mixing the solution;
• building level;
• measuring tape, etc..

Surface preparation

It is necessary to prepare before processing the wall. Plastering with a mosaic mixture requires a level base free of indentations, bulges, and other irregularities. p. You should apply an antiseptic composition to the surfaces, remove any old paint, and treat any areas that have mold or fungus. Putty fills in chips and cracks. Next, a primer is applied to the walls and any exposed metal (nail heads, staples, etc.). The coating has dried completely.

After cleaning, drying, and applying a deep penetration impregnation treatment, wood surfaces are coated with drying oil. The panels are coated with a quartz primer using a roller or a wide brush after 4-6 hours; two coats work best.

It is advised to tint the primer to match the primary finishing material’s tone when using colored plaster. For dependable layer hardening, it is advised to apply the plaster composition the following day after priming.

Technology and conditions for application to the facade and finishing of the base

• optimal time of year for processing facades, temperature, weather conditions;
• compliance with the technology in accordance with the type of finishing mixture;
• rules for applying the base and finishing layers.

Environmental conditions

Plastering should be done in late spring or summer, according to experts, as temperature and air humidity should be considered for external finishing. The ideal temperature ranges from +10 to +25 °C. The maximum percentage of humidity that can be allowed is 80%. The base or wall’s surface shouldn’t be heated by sunlight while operating. In this instance, shading the treated areas will be required.

In three days, the facade coating dries. It is essential to keep the surfaces dry during this period and to shield them from rain if needed. Plastering facades in windy weather is not advised. The work must be delayed until a later time if the air temperature is unusually high or low.

The plaster mass’s ability to harden may be slowed down if the temperature is not met. The particles will be carried away by rain falling on the surface. Strong winds may cause the mosaic plaster used for the base to become unsightly and blurry in its shades.

When finishing, scaffolding needs to be placed 40–60 cm away from the wall panel.

Basic rules for application

Prior to beginning work on cladding facades, a construction mixer is used to further mix the plaster solution. The mixture is spread out evenly in a thin layer. The second layer is applied without waiting for the first to dry before proceeding with the treatment.

Plaster is finished in the basement area by applying 1 m long strips, which are then smoothed to evenly distribute the stone chip grains.

To avoid the growth of mold and dirt, the plaster coating’s lower portion shouldn’t touch the ground. Work is done uninterruptedly moving from one wall corner to the other. The plaster mass must not dry out during distribution, so the treatment is completed right away. Masking tape is used to protect the area’s edges.

It is not possible to apply the mosaic mixture in circular motions, nor can the coating be overly compressed. For the mass to adhere to the surface well, the movements should be smooth and the pressure should be medium.

Technology for indoor use

It will be necessary to mask off untreated surfaces before finishing work is done inside the building. Masking tape is glued along the dividing lines and removed once finishing work is finished. Floor coatings are shielded by a film or covering.

Plaster with medium or small fractions is used for interior decoration. 2 to 3 mm should be the thickness of the standard layer. Two layers of dense plaster material are applied at a time. Construction tape is used to create surfaces with different tones and is used to replicate color patterns or drawings.

Tape is taken off after applying a colored layer. The following day, nearby stains for staining are tinted. The dried coating edge is marked with maslar tape, and the fresh color layer is applied in close proximity to the old one. Stencils can be applied on top of the applied layer to replicate drawings on the plastered surface.

Drying and finishing

The composition should dry naturally for 48 hours following surface treatment. Radiators and batteries in the heating system need to be disconnected or insulated.

As a finishing layer, a varnish coating is applied to the textured surface to give it a glossy shine and increase the finish’s durability. The composition was chosen with the primary plaster’s tone in mind. A roller is used to apply the varnish.

Not every interior design, though, uses varnishing; sometimes, the textured surface is left matte.

Mixture consumption and restoration of damage

Depending on the coating thickness and grain diameter, the plaster mixture consumption per square meter is considered when determining the volumes of building materials.

• fine-grained – about 2-3 kg is required;
• fine-grained – about 3.5-4 kg;
• medium grain – up to 5.5 kg;
• with large-fraction chips – up to 7.5 kg.

The coating has a substantial weight, similar to that of imitation natural stone blocks.

Applying mosaic design to a soft primer mixture during restoration results in a very durable design that is challenging to remove. When repairing old finishes, experts advise covering the mosaic with a new coat. After two days, the next layer is applied. Painting with impregnation, leveling with putty, and priming with a quartz composition are ways to update the old base.
