Why do you need to plaster the walls in the garage

• leveling surfaces for decorative finishing;
• protecting the premises from dampness, maintaining a stable microclimate;
• increased thermal protection and noise insulation;
• protection of walls from mechanical damage;
• ensuring fire safety;
• increasing the durability of repairs;
• prevention of mold, mildew, etc.d.

Plastering garage buildings is an inexpensive, simple, and eco-friendly way to decorate them. Plaster is machine- or hand-applicable, odor-resistant, repairable, and long-lasting.

How to plaster the walls in the garage with your own hands

A suitable composition is chosen in accordance with the design project, local climate, etc., prior to plastering the garage.

Of homes, apartments, and TK buildings may be partially or completely unheated.

Experts advise selecting waterproofing and heat-shielding mixtures for garage building decoration in addition to decorative and aligning materials.

• cement;
• Lime;
• gypsum;
• clay;
• silicate;
• acrylic;
• Silicone, etc.D.

Cement

The garage can be plastered by hand using a cement mixture. The substance has a high strength and quickly freezes to form a dense base. Portland cement serves as the connecting element. Cement-sand compositions are the most widely used. Depending on the intended use, the ratio of cement to river sand may be 1: 1 or 1: 4.5.

When solutions with a high cement powder concentration solidify, they may shrink, resulting in chips and cracks. Consequently, 1:3 is the ideal ratio for a garage building. Plasticizers are added to the mixture in order to increase elasticity. Sifted river sand, slaked lime, and cement in a 7:2:1 ratio are required to make a cement-lime plaster composition.

• high water-resistant characteristics;
• durability of the coating;
• strength;
• the mixture is suitable for external and internal finishing;
• environmentally friendly composition;
• repairability;
• resistance to temperature changes, frost resistance;
• fire safety;
• the solution can be mixed in large volumes;
• good compatibility with other binders;
• resistance to increased air humidity, etc..

The low elasticity of the plaster mixture must be considered; rooms with high vibration loads and seismically dangerous areas should not be coated. After work, the cement plaster-covered walls will need to be moistened for a few days in order to preserve the integrity of the treated surface.

Additional putty compound treatment of the areas in question is advised to improve smoothness. Primers may need to be used to level the base beforehand in certain situations.

Increasing adherence, repairing steel or synthetic plaster meshes, and/or installing beacons are frequently necessary for the design of smooth walls and other surfaces.

Gypsum

A traditional material for interior finishing work is gypsum plaster. The mixture includes ingredients that enhance the material’s performance qualities in addition to gypsum. Because they do not withstand moisture well, compositions based on gypsum are not used to decorate garage facades. The substance can be applied to waterproof flooring, heated or insulated roofs, and garage buildings.

Gypsum plaster mixtures are plastic, simple to use, and rapidly set. As a result, tiny portions of the solution are prepared. The benefit of gypsum mixtures is their excellent vapor permeability and lack of shrinkage, which let you keep the room’s microclimate steady. It doesn’t take extra putty to level the coating, and the finish is aesthetically pleasing. Because the material dries quickly, repairs can be completed promptly.

It is imperative to consider the composition’s sensitivity to water infiltration. High humidity levels in the space can cause gypsum plaster to flake off and lose its beauty.

Because gypsum coating can crack, the material is not advised for finishing garage buildings that are subjected to high mechanical loads.

Lime

Garages can be finished on the inside and outside with lime plasters. The preparation of the mixture is based on suspension, lime dough, etc. Compared to gypsum and cement powder, lime is less durable. Therefore, additional ingredients (cement-lime, gypsum-lime, etc.) are added to plaster solutions. D.). Cement-containing mixtures (up to 20% composition) can be used to decorate facades. The mixture is made up of one part lime to three parts sand.

• high vapor permeability;
• good characteristics of adhesion with different surfaces (brick, drywall, wood made by mineral means);
• ease of application and alignment;
• maintainability;
• a long shelf life;
• Antibacterial characteristics of the mixture prevent the appearance of fungus, mold;
• affordable cost;
• high thermal insulating characteristics of the solution;
• resistance to temperature changes;
• elasticity of plaster and t.D.

Low strength, the requirement to add components to the solution to increase durability, and vibration instability are among the list of drawbacks. You can apply a protective finish to the external surfaces (roof, building facade) to increase the coating’s resistance to water.

Among the frequently used methods for processing garages is the mixture of 1:3:4 clay dough, river sand, and extinguished lime. The amount of sand can be adjusted based on the clay fat content.

The proportions of ingredients used to prepare the laundice-guiping plaster mixture are 1: 3. Fill a container with water, stir in gypsum, and then stir in slaked lime.

Ready-made plaster compositions with lime are made by manufacturers and are readily usable.

Other modern materials for external and internal work

• silicate;
• acrylic;
• silicone, etc.d.

High strength, resistance to alkaline chemicals, moisture, vapor permeability, fire resistance, good adhesion to various bases, and the ability to be used for room decoration are some of the characteristics of silicate plasters. The silicate coating does not shrink after drying, is simple to clean, and does not cause surface cracking.

The material can be used for insulation and processing porous areas like brick walls and aerated concrete blocks. The exorbitant expense, susceptibility to shrinkage, and base vibrations are the drawbacks.

High elasticity, strong adhesion, resistance to water and detergents, a broad range of shades, durability, strength, wear resistance, and vapor permeability are the characteristics of acrylic mixtures. However, it is important to consider the solution’s quick hardening and lack of fire resistance when used without specific additives.

The qualities of silicone plaster mixtures include high elasticity, good adhesion, and durability. Silicone resins form the basis of the composition. A difficult-to-clean polymer film is formed by the coating. In addition, it permits air to flow through, keeping moisture out. The material is resilient to mechanical harm, vibrations, and precipitation from the weather. It is also environmentally friendly. However, the price is quite high.

Choosing the optimal plaster solution

The best technique for plastering the garage walls is a topic of great interest to many. Both exterior and interior finishing are available in mixtures. The composition, technical properties, application guidelines, etc. of the materials vary.

How to plaster the garage from the inside

The walls and ceilings in the building need to be finished. Gypsum plaster compositions are suggested as easy-to-apply plaster compositions for the ceiling. Since the surfaces are not subject to force impacts and abrasion, reinforced mixtures are not used for the ceiling. High-strength materials that are resistant to mechanical loads are needed for the walls.

Cement-sand plasters are used to level the lower portion of the walls, and acrylic compositions are applied as a finishing coat. Plaster that is waterproof can be used to seal these areas. Walls for garages in arid climates can be constructed with a cement-lime sand mixture.

Plastering of external walls

It is advised to use universal or specially designed outdoor mixtures for finishing facades. Waterproofing plaster is chosen for panels that are able to be wet. A cement-lime sand mixture is used for garage buildings situated in areas with low air humidity and a warm temperature.

Necessary tools and materials for plastering walls in a garage

• trowel or float;
• a set of spatulas of different sizes;
• brushes;
• building level;
• ladle;
• plumb line;
• roller;
• tape measure;
• construction mixer;
• rule;
• grater;
• masking tape;
• pencil or marker.

• primer;
• ready-made plaster composition or in powder form;
• water (for mixing the solution), etc..

The list of extra tools includes construction cord, containers, protective compounds, self-tapping screws for anchoring beacons, and reinforcing mesh.

Manual plastering technology for garages outside and inside

It is advised that workers in garage complexes work in temperatures between +5 and +30°C, and that there be no precipitation in the form of rain or snow (for exterior finishing). A minimum of 60% air humidity is needed.

• surface preparation;
• inspection of walls, measurements of height differences, calculation of the volume of plaster, primer;
• installation of reinforcing mesh;
• installation of beacons;
• mixing the solution;
• plastering in several layers;
• dismantling beacons, filling grooves with a mixture;
• smoothing the coating;
• performing finishing work (applying decorative plaster, painting, etc.).d.).

Surface preparation

In order to enhance the adhesion properties of the garage’s walls and floors, the base must be ready for plastering.

• cleaning surfaces from dust, dirt, grease stains;
• removing old fasteners;
• electrical wiring and remaining fasteners must be insulated with oil paint;
• areas of walls damaged by mold and mildew are cleaned and disinfected with a biocidal agent;
• cracks and chips are expanded, dusted off, filled with cement-sand mortar;
• large cracks must be additionally reinforced with fiberglass reinforcing mesh;
• to improve adhesion, smooth concrete surfaces should be processed with an axe or chisel to create notches, and brick walls – with hard metal brushes;
• wooden bases must be sheathed with shingles;
• the base is primed and dried;
• electrical wiring is de-energized;
• sockets are pasted over with masking tape;
• you can protect the window frame, door trims with tape.

Reinforcing mesh

When applied to a fixed reinforcing mesh, the plaster on the garage walls will last longer. If a large coating thickness is intended, the coating is required. Dowels, spaced uniformly across the surface, are used to secure the steel mesh. Plaster mortar or an adhesive base is used to secure fiberglass meshes.

Establishment of beacons

You can get rid of surface irregularities and height differences by plastering on beacons. Using the guides, the plaster mass can be leveled. A variety of materials, including clay mortar, plastic, metal alloys, and wood, can be used to make the strips. Installed at 1-1.5 m intervals, the symmetry of the placement is verified using a stretched cord. Side profiles ought to be positioned no farther than 15-20 centimeters from the wall’s corners.

Splashing

Plaster leveling is done in two to three layers. Splashing must be done first in order to improve the base’s adherence to the finishing material. A creamy consistency is achieved in the preparation of the processing solution. Using a trowel or ladle, the material is sprayed on. Water is used to wet the surface before spraying. There are no spaces between the solutions. The layer’s upper portion is not level. After a full day, the next material (primer) is applied.

Primer

A primer is used to create the leveling coating’s base layer. The consistency of the prepared solution is more viscous. Using a spatula or trowel, the mixture is tossed onto the walls. Using a rule, level the mass from bottom to top after applying the composition to an area of approximately 1 m².

Two to three passes with the tool is ideal. After that, keep painting the walls with primer consistently. The last areas to be processed are the corners and joints. The beacon strips are taken off once the solution has solidified. Using a wide spatula, the grooves are leveled and primer-filled.

Covering with plaster and grinding

The cover layer, which is the last layer, is required to get the ceiling and walls ready for painting. The solution’s component ratio should be 1:1 and its consistency should be creamy. Composition of filler: fine sand. Using a spatula, apply a thin layer of the coating and rub it in right away. Straight-line trowel movements are used to process the surface following circular grouting. There are two passes involved in covering. Fine-grained sandpaper is used to sand the surfaces once they have dried.

Your garage’s walls, both inside and out, can be strengthened and made to look better while being shielded from moisture and wear and tear. Without the need for costly contractors, this do-it-yourself tutorial will show you how to prepare your walls, select the appropriate supplies, and apply plaster smoothly and quickly to achieve a professional finish.

How to correctly calculate the mixture consumption on garage walls

After the beacons are installed, the walls must be measured in order to calculate the amount of plaster mixture needed. Please be aware that different parts of the garage may have varying coating thicknesses. Differences in height are taken into account when calculating the average layer thickness. The area being processed is multiplied by the indicator.

Additionally, 20% of the reserve must be added to the total plaster volume. Online calculators are available on the websites of building and finishing material manufacturers and can be used for calculations.

Features of plastering an unheated garage

Plastering an unheated garage building requires the use of materials that are resistant to water because the room will eventually become condensation-filled from temperature fluctuations. Experts advise applying hydrophobic paint to the surfaces treated with gypsum plaster. Hydrophobic plasters work best for long-lasting repairs. Only when the surrounding temperature is suitable is work done.

Features of performing work with a plastering robot

Utilizing a robot plasterer facilitates faster work. After leaning the unit against the wall, the container is filled with the solution. After turning on the machinery, the surfaces are processed.

What can be used to paint the walls in the garage over plaster

Processing of plastered surfaces is carried out with water-based paints. Acrylic compounds can be used to decorate non-heated garages. More expensive and durable finishing options are the use of alkyd, polyurethane paints.

Decorating the walls inside the garage

You can use original tiles, tool clamps, item storage boxes, and various gadgets to decorate the walls. The best option is to paint the room in rich, harmonious tones. By dividing the colors and adding contrasting horizontal stripes, you can visually expand the space. The use of ornamental plaster, such as "mosaic," "world map," "under a fur coat," and so on, is uniform.

Whether your garage is inside or outside, plastering the walls is an easy project that can make a big difference in the space’s durability and appearance. Your garage walls can be shielded from the weather and general wear and tear with a polished, professional finish that you can achieve with the correct supplies and methods.

You can confidently take on this do-it-yourself project if you follow the instructions provided in this guide. For the best results, the walls must be properly prepared, the right plaster mix must be selected, and the plaster must be applied evenly. Always take your time and follow a methodical approach to guarantee a high-quality finish.
