Decorative plaster for interior wall decoration

Decorative plaster gives interior walls a chic and adaptable finish that gives any space personality and texture. It gives depth and interest, unlike conventional paint or wallpaper, turning walls into more than just a background.

Decorative plaster comes in a variety of textures, hues, and finishes, so it can be customized to fit a variety of design styles, from earthy and rustic to sleek and modern. It’s the ideal option for people who want to give their living rooms a distinctive flair.

Decorative plaster can help conceal wall imperfections and add durability to a room, all while improving its aesthetic appeal. Decorative plaster offers countless options for creating a bold, statement-making feature or a subtle, understated look.

Because it offers a special fusion of durability and visual appeal, decorative plaster is a great option for interior wall decoration. With its help, homeowners can give any space a unique touch by creating textured, eye-catching surfaces that resemble materials like concrete, stone, or marble. It’s also a practical choice because it can be applied to the majority of wall surfaces, is simple to maintain, and can be customized with different finishes and colors to fit a variety of tastes and styles.

Choosing plaster for interior work.

A finish type’s preference is influenced by both its price and attributes. It is wise to take into account the most popular and reasonably priced, conventional and cutting-edge materials in this situation.

The qualities listed are dependent on the binder.

Clay.

A natural mineral group that has historically been employed in building.

Because clay is a weak binder that easily loosens, decorative plaster for interior work is rarely completed with it.

The primary benefit of clay plaster is that it is essentially cost-free. However, the solution’s fat content has a significant impact on its quality.

Slim-body clays. Lack of impurities (sand, rock) is the reason for the loose, insufficiently sticky texture. Useful only in severe circumstances with limited options for construction materials.

The mixture crumbles, peels easily, and is porous and weak. When something is struck mechanically, it breaks.

Standard. The ideal adhesive to waste rock impurity ratio. It is challenging to define "normality," though.

Fatty clays. need to be diluted with sand.

It is not advised to use the solution in its pure form because, as it dries, the dense solution won’t be able to let through enough steam, tearing the clay and causing the plaster to crack.

But using fatty clays is more suitable because the builder can control the material’s fat content.

Reaching the ideal fat content for the clay-sand mortar is quite simple. To get the mass to "come off," or slide off the tool completely and leave it clean without sticking, you must add sand and mix it thoroughly.

Red clay is used to decorate both the outside and the interior. Because clay plaster is environmentally friendly and "breathes" perfectly, it helps to regulate the room’s humidity. However, it is not advised for moist areas (kitchens and bathrooms) where there is a chance of direct water contact.

Since clay can be applied to any base, it is less expensive and easier to repair interior wall plaster than it is to use other binders.

Lime.

Burning limestone yields calcium oxide. conventional plaster binder.

Because lime is a poisonous and caustic substance, precautions must be taken.

However, it becomes antiseptic when dry, losing its harmful qualities. Lime plaster prevents fungus growth, which is crucial when buildings freeze.

Is suitable for practically any base, including cement and sand. It is too powerful for a clay foundation, though.

Lime decorative plaster is a fairly traditional material for interior work.

The kind and amount of additives and other binders control the technical properties of lime mortars.

Mixture of lime and sand. Useful only in reasonably dry spaces.

Cement and lime. A long-lasting coating for finishing bathrooms, basements, facades, and living rooms, both inside and outside.

Gypsum-lime plaster. A cheap, ineffective fix. only when working inside.

Gypsum is added to the layer to smooth it out, lower the plaster’s heat conductivity, and quicken the drying process.

For facing clay-sand plaster, lime-clay is utilized. As a result, the surface becomes stronger.

An inexpensive and simple-to-apply decorative plaster for interior design projects.

Quicklime can be harmful! Boiling, bubbling water and caustic fumes are released during the preparation of lime dough. You run the risk of burns or poisoning if you disregard safety precautions.

Lime is inexpensive but not free. Its mixtures are strong, antimicrobial, and absorb a lot of steam, enabling you to adjust the air humidity to your preferred degree.

Gypsum.

Since ancient times, gypsum, a naturally occurring mineral (sulfite), has been used in building. Its peculiar qualities include its quick setting time, ease of processing, and poor heat conductivity.

Applying thick layers of gypsum plaster (up to 50 mm) is possible. Plastic is more comfortable to work with than alternative materials.

Gypsum-based decorative plaster is increasingly widely used for decorating interior walls. It is only useful, though, in normal or low humidity conditions.

The quality of the material is determined by the size of the sand grains in the mixture and is linked to the classification of gypsum compositions:

Finely divided. Ground sand, crushed (0.6 mm in diameter). Using a steel tool, they are flawlessly polished, but the application is done thinly (to avoid cracking). Cover facing and finishing.

Medley granular. The primary ingredient in plaster (sand grains, 0.5–1 mm in diameter). Universal: It can be applied thickly (up to 30mm) without the need for extra finishing.

Coarse-grained. made with gross alignment in mind. Because it contains large sand with fractions diameter of more than 1 mm, it is the most durable and does not crack even with thick application (up to 50 mm). plaster with gypsum primer for interior work.

Using the mixtures for purposes other than intended is not practical. Using finishing solutions, you can achieve polished, smooth surfaces. However, applying a thick layer of them will undoubtedly cause them to crack. Coarse-grained ones won’t break, but they won’t function flawlessly because of the excessive filler.

The most common use of gypsum plaster for interior work is in decorating departments. This is partially caused by the misconception that compositions containing gypsum are the most practical, warm, and ecologically friendly.

Actually, any solution can be used to decorate.

Cement.

In high-humidity rooms and on plastered facades, cement-sand mortar is utilized. But because of its large heat capacity, it is not very well-liked in this direction. The process of thermal energy accumulation and storage in concrete is slow. The heat that was absorbed is released later on when the heat source cools.

Of course, this is all theoretical. In actuality, the plaster is always cold to the touch because all of the heat "goes" into the wall.

Because cement-sand finishing does not "breathe" well, moisture and steam condensation are common. When plastering interior walls, a heat-insulating filler (sawdust, perlite, and polystyrene chips) is added to the cement-based mortar mixture.

With the exception of gypsum, cement plasters are applied to all mineral bases. Their superior strength and high tension cause them to separate from the gypsum along with some of its surface particles.

Based on their intended use, they are separated into:

Leveling up. coarse filler mortars. The two main goals are leveling and repair.

Finishing and decorative. Among them are fillers with fine grains. Additionally, a sand-free cement mortar is utilized (a covering composition of plaster without further puttying).

Particular mixes of cement and sand that contain extra ingredients (sound, heat-insulating, antiseptic, etc.).

Plaster for internal and external work that is aligning and decorative. It is easiest to do with your own hands, even when compared to clay.

Don’t use more than one layer.5 to 2 cm. Plaster must be reinforced if necessary in thicker coatings.

Polymers.

Synthetic resins (silicone, silicate, and acrylic) serve as binders. The filler affects the color and texture.

Offered for sale as ready-made plaster for both indoor and outdoor use. Making it effectively at home is not feasible.

Finely distributed filler is a component of smooth plaster. used to produce coatings that are smooth and textured.

Textured. incorporates exclusive structuring additives. For instance, natural or synthetic fibers.

With broken stone (pebbles). Unpainted and multicolored stone chips are used as decorative accents in the form of small pebbles.

Flock plasters are composed of acrylic flakes, also known as "chips." utilized to create high-end decorative coatings.

Compounds made of polymers are costly. It is therefore more practical to use them exclusively for decorative finishing and to use a less expensive solution to create a "substrate" that levels the base.

The strongest, longest-lasting decorative plaster for both interior and external finishing forms a secure, long-lasting foundation. Abrasion-resistant, fade-resistant, shockproof, and able to be laid on any organic or mineral base. however pricey.

Savings when plastering walls.

The cost of finishing plaster is a factor to consider when doing interior work.

One of the easiest methods to save money is to produce plaster mortar on your own. Pre-made mixes are inherently more expensive than homemade ones. Yes, buying them is simpler, less hassle, and requires less time. There are three strategies to lower the funding cost:

Work that is entirely independent. You are able to prepare and implement a solution on your own. Cement, lime, clay, and gypsum binders are used for this.

Blending of different compositions. The priciest compositions are made of polymers; lime ones are less expensive than others. Thus, if you purchase pre-made plaster solutions, you must use inexpensive homemade underlays to cut down on their consumption. Level the walls with cheap plaster first, and then invest in high-end finishes.

Self-performed partial plastering. Workers charge more per square meter when finishing with pricey decorative mixtures than when using regular plaster. Decorative finishing, on the other hand, is frequently simpler to apply than "smoothing" an ideal canvas with straightforward plastering.

It is therefore more practical to give them the task of preparing, paying the lowest possible cost per square meter. You arrange the decorative coating yourself. cutting expenses per square meter by at least 50%.

The composition of the plaster and the method of application determine how well interior walls with decorative plaster can be repaired.

The least expensive binder for a solution made by hand is clay, while cement is the most straightforward. Lime is more toxic than other fruits and vegetables, but it’s also more flexible. Because gypsum is a costly material, it is more convenient to purchase it as a ready-made dry mixture.

Marble chips and paints can be added as decorative elements to homemade concoctions to achieve a "Bark beetle" effect.

Basic rules for work.

Every plaster solution is unique in both composition and qualities. They are all bound together by a few basic guidelines that let you complete the task at hand at a very respectable level and prevent serious mistakes.

How to independently prepare plaster for interior work.

Regardless of the binder, it’s critical to adhere to the directions exactly.

The amount of the solution that can be used right away is prepared. Simply add a small amount of water to ready-made plaster for interior work that is sold in buckets; no preparation is required.

Combination of different binders.

Applying strong coatings to weak bases is against the main rule. Put differently, every layer after that should be marginally weaker.

Alignment.

It is necessary to correct distortions when there are strong slopes. Beacons are used in its production. Internal wall plaster is applied thickly if the composition of the plaster permits; if not, reinforcing meshes are utilized.

Preparation.

Surface preparation is always necessary for all types of plaster, including clearing away debris and dust and removing any deterioration.

Primer must be applied to the entire surface.

Application.

Plaster is applied in 1-1.5 sq. m. segments. This enables you to level the solution appropriately. Working with large areas is less convenient as the solution starts to set.

Facing.

Applying finishing layers in accordance with the guidelines. Particularly when creating decorative finishing, there are a lot of options. The primary guideline is to adhere to the directions.
