Concept and features.
Plaster is a layer of mortar that has hardened and is used to finish both residential and commercial spaces. Ordinary solutions are used to both protect the facade from harmful environmental conditions and prepare surfaces for decoration. When the following coatings need to be created, special solutions are used:
- Shielding membranes.
- Partitions.
- Isolation of surfaces from the penetration of various types of radiation.
When finishing structures, decorative solutions are employed to improve their visual appeal.
Plaster is used both decoratively and to level the surfaces of rooms during construction. It can produce a brickwork-like effect. Joints are frequently created during the construction process when piece materials are used, and plaster with cement type can best conceal these joints.
Rooms can be made cozier by using solutions of different colors. In addition to covering up uneven walls or ceilings, decorative cement plaster helps a room stay warm and has good sound insulation qualities.
It is frequently used to give industrial and residential building walls fire resistance.
What to choose for finishing?
You must comprehend the main distinctions and characteristics between gypsum and cement plasters in order to ultimately determine which is superior. For instance, plaster solutions come in a variety of forms and variations these days, based on the constituent ingredients.
Therefore, a cement mixture used to plaster walls presumes the presence of cement, but other materials can be used in place of cement entirely or in certain amounts:
While there are many options available, plaster mixtures with cement or gypsum for wall and surface finishing are typically the most popular.
The exceptional strength and durability of this material set it apart. Cement plaster can have different proportions of its constituent parts depending on the base material that goes into making it. Therefore, cement plaster for internal work as well as the one used for external decoration can be based on sand or lime, in addition to the constant components that are used in each solution (cement, water).
In order to create the final sand-based building material, four parts cement to one part sand are typically used, and water is added to the mixture to achieve a workable consistency. This mixture is used as a facade cement plaster to create smooth surfaces with proper angles and to seal interior building walls that have depressions and cracks in them.
Hidden and obvious advantages.
Slaked lime is added as the main component to make up for the main drawback of sand mixtures, which is their significant weight. Portland cement, water-retaining additives, different fractions of quartz sand, and other ingredients are also included in facade cement plaster with lime added.
Such cement plaster has a good ability to stick to the surface it is applied to and provides the appropriate microclimate and humidity level for the structures being built.
This combination has a number of benefits. First of all, because of its extreme durability, repairs can be made much less frequently after use. Second, there is no need to add supplementary additives to strengthen it because of the high degree of adhesion, or adhesion to the surface, which guarantees long-term preservation. The proportions of cement plaster are inexpensive, as they don’t require costly or uncommon materials.
When using gypsum plaster on surfaces that other types of cement cannot handle, it is a convenient option. These could be portions of painted walls or wooden or plastic surfaces. Additionally, it doesn’t require the same meticulous, multi-step application method as cement.
For finishing the facade, damp, and damp rooms that are exposed to moisture, this material is therefore more appropriate. When it comes to finishing surfaces that cement just won’t stick to, gypsum plaster can help. When working with surfaces made of clay, polymer, wood, or ceramics, this benefit is utilized.
How to make cement plaster for interior work with your own hands.
- The first of which is necessary for binding the others (this is often cement, lime or clay).
- The second component acts as a filler and gives the main weight to the material (usually this is sand).
- The third element is water.
If you make the solution at home, you don’t want to go against the proportion. Equal amounts of binder and filler components make for the best combination.
Otherwise, excessive cement application will result in numerous cracks after the material hardens, and excessive sand addition will cause the mixture to become brittle and crumble. Sand and cement combined in a one to three ratio are the most commonly used proportion when preparing the solution.
When creating lime mortars, consideration is given to the fat content of the lime. For every ten kilograms of mortar, add one kilogram of cement to boost its strength. Although a construction mixer works best, you can mix it with a shovel or other auxiliary tools.
A strong and adaptable option for both external and interior wall finishes is cement plaster. It offers a robust, long-lasting surface that can be tailored to have a variety of appearances, from polished and glossy to rustic and textured. Cement plaster is a sensible option for improving the look and longevity of walls and is ideal for withstanding weather changes and wear. This makes it appropriate for a variety of applications, including both residential and commercial buildings.
Features of the technology.
To perform plastering tasks on your own, you will need to gather the following equipment:
- A device for throwing onto the wall.
- A leveling agent.
- A spatula for rubbing the mortar.
To prevent the mortar’s liquid from penetrating the surface’s porous structure, prime the area to be treated or just moisten it with water before applying the prepared mixture. Grouting should be done after the trowel-applied, stretched, and leveled layer has dried.
This is accomplished by applying a more liquid-consistency solution to the surface that has to be treated for final leveling, using a float.
Using a specialized mesh to reinforce the plaster layer can help to increase its strength. In order to stop fungi from growing on the dried layer, specific preparations can also be applied to it. You must follow all safety precautions when doing all of these tasks. You must wear a work robe, wear a respirator or mask, protect your hands with gloves, and work in a ventilated space in order to accomplish this.
After application, the dried solution takes about a month to reach its ultimate hardness. When drying is artificially accelerated with air blowers, cracks may develop.
How to make a functional and aesthetic repair.
Decorative plaster is frequently used to enhance the visual appeal of building facades and rooms. This technology can be utilized with your hands and is reasonably inexpensive.
The fact that decorative treatment is applied to level surfaces won’t be shocking. This most frequently occurs on home facades following insulation work. Traditionally, the building’s surface is primed before the solution is applied to improve the bond between the plaster and the base. For items whose finishing is not finished before the first frost, it is also appropriate to apply a primer in order to improve their preservation.
Dry mixtures or ready-made plaster are used for this kind of wall treatment. Using a spatula, apply it, and then rub it in. The rubbing technique is particularly important because it provides the building’s finishing with a distinctive pattern. The plaster will have depressions and grooves when unique tiny balls are added to the mixture, giving it a unique flavor.
When working on a surface, it’s crucial to keep going until the entire area is finished. If you reverse this and start working after a portion of the wall has dried, you risk creating stains and tonal shifts between the areas you’re processing. Avoid working in hot weather as the plaster’s quality won’t be improved by quick drying. The surface is primed once more after the solution has dried fully.
Applying a layer to the walls and then blowing hot air at it can seriously harm it. The material may sag, crack, and deform due to partial drying or an uneven distribution of air jets, all of which are obviously undesirable.
It is preferable to add plasticizers to the mixture to speed up the hardening process instead of using heat treatment, as this will delay drying by up to several days without changing the solution’s structure or causing bubbles and cracks to form.
