Plastering operations must be completed in the finishing stages - a set of procedures used to create a smooth surface and even surfaces protected from moisture and other unfavourable elements, such as heat and sound insulation. Only an expert will cover the surfaces with plaster to get these benefits - this task is outside the scope of those without expertise. For this reason, plastering is often outsourced to specialized companies.
Types of plaster works
Plaster works are classified by category, with the option determined by the type of surface, material, and ultimate goal. Dry plaster is a term for applying gypsum cardboard sheets to prepared surfaces after they have been faced. This technique has several advantages, including high processing speed, smooth surfaces and edges, and the opportunity to work with anybody with any level of training. Plastering also provides a finished surface over the masonry that is firm and smooth; hence it enhances the appearance of the building.
Wet assuming proper plaster thickness is a popular choice for a home owner's bathroom remodel. This is a typical method for applying a wet solution on the finished plaster surface. The work is done in layers, with covers alternating with primers, levels, and smoothing.
The two distinct types of plastering work are horizontal plaster exterior corners work. The primary goal is to provide the building's aesthetic, protect load-bearing walls from weather, and close the insulation layer. Therefore, it is critical to use high-quality wall surface preparation and recommended trustworthy materials when performing tasks.
The outer layer, which is made up of the mural material, has a smooth finish. Lime-based mortar for brick and concrete masonry block walls plastering (for example, in ceilings) and lime-gypsum mortars for wooden and plasterboard surfaces are used to fill characters in the nutria of buildings. The process can be done manually or automatically with specialized equipment.
The final coat should be made in an actual plane using a straight edge. Repairing plaster must be one of the essential parts of a finishing stage project. The final coat should be smooth and free from any visible irregularities.
Let's learn the plastering work procedure in easy five steps:
1) Preparation of surface area.
2) Making of plaster mix
3) Applying base coat
4) Applying the final coat.
5) Applying a primer layer.
Use high-quality plaster materials, such as lime or gypsum-based compound, to prepare the surface for plastering work. Ensure all plasters are well mixed before use and applied in thin layers, allowing enough time for drying between applications. The final coat can also be done manually using a particular application and a level. Keep in mind that the surface must be clean and dry.
Specifications for integral cement waterproofing compound, which requires 15 to 30 days of drying, can be restored over the waterproofing compound. A sealer is then applied on the surface and protected by a finished plaster coat. In the areas where plaster thickness is expected to exceed 20mm, multiple coats of plaster must be applied in receding thickness. Before using the second coat, damp the first coat evenly.
The installation of integral cement tile (ICF) profiles and surkonstruktsii retaining walls and slopes require specialized labour and equipment, including high-capacity pumps, mixer trucks, and so on. Operators must have a certificate of professional competence to work with such materials.
It should be noted that the installation works of plastering are significant for the overall appearance and durability of the object. Improper execution can lead to substantial losses and future repair costs. To avoid these problems, it is recommended to contact a reliable and experienced company.
Specification for coarse and fine aggregates for natural sources for concrete.
In construction, a wide range of aggregates from natural sources is used. For example, in the form of gravel, they are most often used in concrete production for sidewalks and streets.
Introduction to minerals processing technology
Aggregate is a solid material with various forms and properties depending on its chemical composition, mineralogical structure, and method of processing. The most common natural aggregate is gravel, which includes pebbles and stones with a diameter of more than 25 mm.
Purpose aggregates for concrete
Aggregates are needed to produce concrete in the following cases:
- when the use of chemical additives is not allowed;
- when dealing with solid rather than liquid components;
- when a high-quality product is required.
Plastering concrete masonry block walls
Using a mortar (lime and cement) on the cavity wall made of brick or concrete blocks is called plastering.
Lime plaster refers to organic binding material with small rectangular particles used for interior and exterior surfaces, while gypsum plaster is often used indoors in dry form. The use of lime plasters can also be used on walls with gypsum plaster.
It is essential to know that the lime particles are usually different in size than gypsum plaster, so it takes less time to dry. However, the binding material must first be wetted before applying the dressings. After application, lime surfaces can not be washed down with water for 2 to 3 months, during which they must remain dry.
In the production of lime plaster, masonry lime with a good amount of hydration is preferred. Such applications on surfaces with a humidity content below 15% can be applied on interior and exterior surfaces. Avoid using calcium-based masonry plaster for inside plastering.
To reduce the amount of humidity in the wall, a pore layer is applied before applying lime plasters. The surface must be dry and clean. Sometimes wood ash or sand can be used as fillers when preparing the base for plastering.
Lime plaster works well on mineral substrates such as concrete, brick, and stone. However, to improve the adhesion of the application to the substrate and increase its resistance to weathering, it is recommended to use a bonding agent.
The main types of surfacing finishes for lime plaster are:
- rusticated (a textured surface with large and small projections);
- troweled (smooth with a small amount of projection).
The main types of finishes for gypsum plaster are:
- textured (stucco, sandblast, etc.);
- carved (Modello, Venetian Plaster).
Lime plastering works step by step.
- preparation of the substrate;
- mixing ingredients for plastering work;
- wetting the surface - before applying lime plaster, it is essential to moisten the substrate so that the solution penetrates. If necessary, add water when mixing materials to achieve a uniform consistency; and then apply the first layer of plaster;
- the second coat is applied after half an hour and then leave it to dry. To speed up the drying process, you can use a fan or some other device such as a heater; and then apply the third coat - this time with a thicker layer than before with small projections that allow for better adhesion of the next layer;
- finally, apply a protective coating.
It is essential to ensure that the lime plastering work is smooth and without defects. To do this, it is necessary to make several test coats before the final coat is applied.
What are the benefits of plastering?
There are many benefits to plastering, so it is an essential step in the finishing stages of a construction project. Some of these benefits include:
- creating a smooth surface
- creating even surfaces
- filling in irregularities
- protecting the surface from weathering and damage.
Plastering is an essential step in creating a durable and aesthetically-pleasing finished product. Therefore, it is crucial to use high-quality materials and take care of applying the plaster coats. By doing so, you can ensure that your project looks great and lasts for many years to come.
How to order high-quality plaster walls?
Plaster - a light and fanciful material that needs careful preparation of the solution, adherence to technology, and precise movements during application. If you don't consider any details, for example, the surface won't be as smooth or will have cracks after a while. There are several substances: regular plaster work, simple improved high-quality decorative plaster. The ability to work with a wide range of materials is essential. Wizard selection criteria: Analyze the roles for each position in your profile.
