Plastering walls outside and inside the house

Plastering the inside and outside of your home’s walls is an essential step towards improving both its appearance and longevity. Plastering the exterior and interior of your home not only makes it look better, but it also has functional benefits like insulation and weather protection for the walls.

Applying a layer of mortar mix to a home’s exterior walls is known as exterior plastering, or rendering. This layer covers any flaws in the underlying surface and aids in creating a smooth finish. It prolongs the life of the building materials by serving as a barrier against wind, rain, and temperature fluctuations.

Conversely, the goal of interior plastering is to give your home’s walls a uniformly smooth surface. Plaster is applied to the walls and ceilings in this process, after which they can be painted or decorated to suit your taste in design. In addition to enhancing the aesthetic appeal of your living areas, interior plastering serves as a foundation for additional finishes like wallpaper or ornamental painting methods.

Achieving long-lasting and aesthetically beautiful results requires careful selection of plastering materials. Cement-based renders are frequently used for external applications because of their resistance to weathering. They are applied in layers to create a sturdy, weatherproof finish by mixing them with sand. Gypsum-based products, which provide a smooth and manageable surface that can be painted or embellished with different textures, are frequently used in interior plastering.

Whether you’re building a new home or remodeling an existing one, a warm and secure living space depends on quality plastering. Comprehending the distinctions between exterior and interior plastering methods will enable you to make well-informed choices regarding your DIY projects.

Plastering walls is more than just a finishing touch; it’s an essential part of safeguarding and enhancing your living area, whether it’s outside or inside your house. Plastering calls for careful consideration of materials and techniques in order to provide a smooth and aesthetically pleasing surface as well as increased durability against weather elements. This article examines the fundamentals of both exterior and interior plastering, outlining the main distinctions and providing helpful advice for attaining a faultless finish that improves the appearance and durability of the front of your house.

Application of plaster on the internal walls

  1. Preparation of the base. It is necessary to remove all protruding elements, fasteners. Fill in cracks with a repair solution, and soil the base. On concrete or brick walls, it is necessary to make notches, and deepen the seams. This will increase the adhesion of the solution and the base.
  2. Installation of lighthouses. These are metal elements that will help to qualitatively align the walls without difficulty.
  3. Spray with plaster solution. The composition is applied by a bucket or a small spatula and is 80 % of the entire thickness of the layer. This part does not need to be aligned.
  4. Application of soil (second layer of plaster). Align, the resulting solution, using the rule, focusing on the established beacons.
  5. Execution of covers. This is the third layer of plaster, the thinnest. He eliminates all minor irregularities and shortcomings.
  6. Grouting – concluding the stage of plastering. Perform before the covering dries.

Plaster can be applied manually or with the aid of a specialized tool. an application process that is automated and much faster than manual. Furthermore, the layer becomes more uniform, meaning that less work will be required to achieve the ideal smoothness of the walls.

How to apply plaster in new apartments correctly

When purchasing an apartment in a newly constructed building, one must be ready for the possibility that the walls may give way at any point. Builders without responsibly related to the performance of such work. It is therefore preferable to give up on such work completely.

If, however, everything is finished, you will need to repaint the walls. To achieve this, the applied layer is removed to the base, and the work is carried out in accordance with the plan mentioned above. You should never overlook the deep penetration and lighthouse installation process. The primer will aid in strengthening the solution’s bond with the base more consistently, while the beacons will streamline the alignment procedure.

Necessary tools

It is advisable to gather all necessary tools and materials before beginning any work. This will make the plastering process go more quickly and with less interruption.

  • A mixture for plastering. Maybe ready – sold in containers, or dry – to be in bags and before applying you need to prepare a solution with the addition of water.
  • Punch with nozzle for mixing.
  • Width.
  • Sprinking bucket.
  • Rule.
  • Metal beacons.
  • Dowel.
  • Building level and plumb.
  • Deep penetration soil.
  • Roller or wide brush for soil application.
  • An old ax for creating notes on concrete or brick.

Stucco solution techniques

Plaster can be applied manually or by machine, as was previously mentioned. However, since these gadgets are pricey, you shouldn’t purchase them specifically. You have two options: hire someone or use the manual method.

There are three distinct steps that you must take in order to apply the solution correctly:

  1. Spray.
  2. Application of soil.
  3. Creation of covers.

Applying soil right away can be done without spraying if the base has not changed by more than 5 mm.

Application of the first layer – spray

It is imperative that you safeguard both yourself and other surfaces from the solution in order to complete this plastering step. When performing labor, an individual dons a respirator or mask along with safety glasses. Plastic wrap is used to cover the canvas around windows and doors.

A solution is made for spray that has a thick, sour cream-like consistency. He needs to close all the gaps and indentations made on the foundation. After gathering the solution in a tiny bucket or on the cell, it is hurled onto the base with a quick wrist motion.

Note that all movements must be made at an equal distance from the wall. It is not necessary to overdo this, though, as the solution will scatter in various directions. The surface is processed in its entirety and then given some time to dry. The next layer will lie poorly if the solution dries out.

Application of the second layer – primers

The solution is prepared with a slightly thicker consistency than before for applying the primer. Use a rule and a narrow spatula for work. A solution is thrown in small portions with a spatula, and the rule levels it.

The tool is firmly pressed up against the guides if lighthouses were installed. The solution needs to be filled with all of the spaces left by the spraying, evenly moving from below-up and simultaneously oscillating from side to side.

Multiple surfaces are separated from one another. Proceed to the other after processing the first. Make sure to give the joints more consideration. The applied solution needs to be wiped after being somewhat grasped.

Applying the finish layer – covers

Applying covers is the next step you can do once the soil dries. Using a mixer, the solution for this step is meticulously prepared. It is very difficult to manually make the perfect consistency without any lumps. It is recommended that all dry ingredients be sieved in order to eliminate any particles larger than 2 mm.

The layer will be completed. If everything goes according to plan, you can glue the wallpaper and stain the surface after the solution dries. A wide spatula must be used to apply the prepared solution. This is carried out in this manner:

  1. A narrow spatula, a small amount of solution is laid on a wide tool.
  2. The spatula is pressed against the wall and make a sweeping movement from the bottom-up. Thus, the solution seems to rub into the base.
  3. Some claim that arc movements are much more convenient. But then everyone chooses a suitable option for himself.
  4. Each subsequent movement of several millimeters covers the previous layer.

The applied layer needs to be allowed to grab before a black grout and smoothing are done.

Wall plaster technology using dry gypsum mixture

For example, rotband, a dry gypsum mixture, is frequently selected to apply a finish layer. Because the base will be white, any color of wallpaper can be painted or adhered to it, making it visually appealing.

Make sure you read the instructions before starting to prepare the solution. The amounts in which the components should be combined to obtain a solution with the required consistency are specified by the manufacturers.

The application technology needs to abide by the unique environmental requirements:

  • Air temperature, as well as the base, should be within the framework of 5 to 25 ° C.
  • Gypsum putty is afraid of moisture, because open packages with the mixture must be stored in a dry room. Such plaster is not suitable for decoration of the facade and rooms with high humidity.
  • The solution is quickly set, because it is prepared in small quantities.

How to apply gypsum plaster?

It is applied in the same way whether it is a cement-sand solution or one that includes gypsum. A small quantity of material is first pounced, and it is then leveled using a spatula or rule. Should the gypsum composition be selected for the finish plaster, the mixture is gathered onto a broad spatula and applied to the base, which ought to be slightly damp.

Gypsum solution sets quickly, so you have to work quickly. Its properties are lost when it hardens, so it cannot be diluted with water or other liquids. A unique tool dipped in gypsum milk is used to wipe the applied layer after it has been grabbed. This will impart strength and smoothness to the plaster.

Putting or smoothing walls

Use a special grater for grout. You must use a smaller grater or take a half-at-a-half for narrow areas (near door and window openings). The hand makes a circle and revolves counterclockwise. Work with assurance, but avoid going overboard to avoid ripping off the layer that has been applied.

A grater with a rubber or metal lining is also used for salting. There are now just vertical and horizontal movements. Prior to moving on to horizontal motions, the wall in the floor is first smoothed out from the ceiling. The ceiling is leveled across and then along the window opening.

Application of plaster to external walls

One well-known method of shielding the main structure from external influences is to plaster the facade. Synthetic ingredients are added to the mixture during production to enhance plaster’s qualities.

The primary benefits of these finishes are:

  1. Fire safety. Plaster will protect any base from fire.
  2. Duration of operation. Some manufacturers give a warranty for 20–25 years.
  3. Accessibility – the price of the compositions is democratic, because almost everyone can purchase them.
  4. Sound insulation – the thick layer leveles the penetration of extraneous noise into the room.
  5. Universality – can be applied to different grounds (brick, aerated concrete, foam, foam and wooden walls).
  6. Additional components reduce the weight of the finish, therefore it does not create an additional load on the main structure.
  7. Resistance to temperature differences.

Types of decorative facade plasters

Plaster is used as the primary decorating material on the facade in addition to serving as a leveling layer prior to painting or tile fastenings. To achieve this, unique ingredients are added to the mixture, creating an inventive pattern when grouted in. This is referred to as the "lamb" or "bark beetle."

What sets apart the plaster’s primary composition is:

  • Mineral – consist mainly of cement and sand. Available option that has vapor permeable properties. Quite strong and easy to work with it. Previously, such a solution was applied to the wall “fur coat”. The mixture was pounced on the surface and was unequone.
  • Silicate – manufactured on the basis of liquid glass and sold only in the ready form. Do not accumulate dirt, durable. The price is not different from the previous option.
  • Acrylic – have synthetic resins in the composition. The mixtures are already collated, but the pigment is quickly destroyed under the influence of sunlight. This drawback is eliminated by staining. The solution is applied easily on any surface, including gas -sized blocks.
  • Silicone – the most expensive option among decorative plasters for facades. The solution is quickly and easy to apply, but you need to be able to work with it. Such a finish will last a long time unchanged.

Stages of work

Following this plan will ensure that plastering the facade’s surface is done correctly:

  1. Preparation of the base.
  2. Installation of insulation.
  3. Applying a solution for plastering.

You should go into greater detail about each of these stages because they each have unique characteristics.

Preparation of the processed surface

In addition to serving as decoration, the facade’s decoration keeps the walls safe from damage and heat loss because the surface needs to be ready for work. For this:

  • All hung structures are removed, which can interfere with the application and leveling of the solution.
  • Fasteners, spots of dust, dirt, fat and life of living organisms are removed.
  • Fill in cracks and potholes with a repair solution.
  • If there are no large differences on the surface, then the black alignment for the insulation does not need to be done.
  • Treat the surface with deep penetration soil.

Installation of insulation

You can begin warming the walls once everything has dried. Choose leaf insulation to accomplish this. Minvate, foam, or foam are appropriate.

Take the following actions to fix the material reliably:

  • Install the starting profile. He will perform the support function. The guides are fixed exactly horizontally.
  • This will guarantee the reliability of the entire structure.
  • The insulation is installed from the lower left corner of the building.
  • For consolidation, select the adhesive composition and mechanical fasteners. This option is great, if the insulation will be covered with plaster.
  • In the subsequent rows, the joints of the material should not coincide. To avoid this, the plate is shifted to half the lower.
  • Joints are treated with sealant.
  • Further on the insulation fix the reinforcing mesh. Prepare a solution for plastering and applied to the material. A fiberglass grid is applied to a damp solution and smoothed with a spatula so that it drowned.
  • After drying the layer, you can proceed to applying decorative plaster.

Application of decorative plaster

The manufacturer’s instructions are followed when preparing a decorative plaster solution, as stated on the packaging. It is imperative that the proportions be held differently; otherwise, the solution will not work.

  • The finished solution is typed on a wide spatula and applied to the wall.
  • The thickness of the layer corresponds to the size of the mineral components that will create a pattern when grouting. If the texture is created using a decorative roller or improvised means, then you need to focus on the depth of the picture.
  • Should work with a block method. Process a small section of the wall, and until the solution has completely frozen, give textures.
  • After that, all the walls are plastered and the textured drawing is made by them until they dry out completely. During this period, the surface is protected from direct sunlight and rain.

You must begin staining if the mixture was used without a coloring agent. Using a compressor to apply paint in a homogeneous layer is preferable.

Plastering walls—both inside and outside the house—is essential to improving your home’s durability and appearance. A well-done plaster job on the outside not only enhances the structure’s appearance but also shields it from environmental factors like wind, rain, and sunlight. It creates a strong barrier that prevents moisture intrusion, which over time could cause structural damage.

Plastering inside the home adds to the overall comfort and atmosphere in addition to being a decorative finish. Smooth, well-plastered walls give interior designers a blank canvas to work with because they reflect light well and foster a cozy feeling. Plaster also contributes to the regulation of indoor humidity levels, which is advantageous for preserving a healthy living environment.

Selecting the appropriate kind of plaster is crucial to attaining the intended outcomes. Because they are strong and resistant to extreme weather, cement-based plasters are frequently used on external walls. They are perfect for outdoor applications where resilience is crucial because they have outstanding durability and are resistant to cracking.

However, due to their superior finish and ease of application, plasters based on gypsum are preferred for interior walls. They offer a smooth surface that’s ideal for painting or applying wallpaper, giving interior designers a multitude of options. Additionally aiding in acoustic insulation and lowering noise transfer between rooms are gypsum plasters.

Plastering projects require careful planning to be successful, whether they are done indoors or outdoors. Plaster coat adherence and durability are ensured by surface cleaning, crack repair, and the use of appropriate primers. Layering and smoothing are two expert application techniques that improve the plastered walls’ durability and final appearance.
