Rust on welds and faded paint are the first signals that a metal garage requires immediate restoration and comprehensive finishing. Ignoring the corrosion of metal leads to the destruction of load-bearing structures, drafts and damage to the car inside the room. Quality design of the iron garage begins with a complete cleaning of surfaces and application of anticorrosion primers, which will become a reliable barrier to moisture. The wearer must understand that the decorative layer without prior chemical protection will last only one season.
The choice of the processing method depends on the state metal-frame and the financial capabilities of the owner. Modern polymer coatings or classic oil paint require a completely dry and fat-free surface for adhesion. If you miss the stage of eliminating foci of corrosion, oxidation will continue under the layer of new paint, reducing all efforts to zero. Therefore, before the start of work, it is necessary to conduct a thorough defect of all walls and roof.
Surface preparation and elimination of corrosion
The first stage of the work is the mechanical cleaning of all available surfaces from old paint, rust and dirt. For this purpose, use angle grinding machines with petal discs or special nozzles-brushes. Particular attention is paid to the lower perimeter of the walls and corners, where moisture most often accumulates. Metallic surface shall be cleaned to a characteristic shine to exclude oxide residues.
- 🛠️ Use of a rust converter to neutralize residual oxides in hard-to-reach places.
- 🧹 Degreasing the metal with a solvent (white spirit or acetone) before applying the soil.
- 🔨 Correction of dents and welding of through holes, if any, in the skin.
⚠️ Warning: When working with Bulgarian and chemical compounds, be sure to use a respirator and protective glasses, as metal dust is toxic.
After cleaning, it is recommended to cover the metal immediately. rust-plate. Such formulations contain corrosion inhibitors that stop the chemical oxidation reaction. Apply the soil better spray gun for uniform coating, but you can use roller. It is important to handle all hard-to-reach places, including the inner corners and joints of sheets.
Selection of materials for external finishing
The appearance of the garage determines not only the aesthetics of the site, but also the durability of the structure. The market offers a variety of options, from budget painting to expensive siding. Metal siding It is one of the most popular solutions due to its strength and variety of color solutions. It does not require frequent care and perfectly protects the main frame from ultraviolet light.
The alternative is to use flooring polymer-coated. This material is easily mounted on existing walls with the help of screws with rubber washers. It is important to choose a color that will harmonize with the roof of the house or fence. Also popular are acrylic and alkyd enamels, specially designed for outdoor metalwork.
When choosing paint, pay attention to the labeling metal-colour. Alkyd formulations create a strong glossy film, but require perfect preparation. Acrylic paints are more elastic and do not crack at temperature deformations of the metal. In any case, the application should be made in dry weather at temperatures above +5 degrees Celsius.
Technology of insulation of metal garage
The design of an iron garage is impossible to imagine without high-quality insulation, since the metal has a high thermal conductivity. Without the insulating layer inside, it will be cold in winter and hot in summer, which will lead to the formation of condensation. condensate It is the main enemy of the car, causing rapid corrosion of the car body.
The most effective material is considered polyurethane, spray-painted. It creates a monolithic layer without seams, completely eliminating bridges of cold. However, this method requires professional equipment. A more affordable option is to use the plates polystyrene (EPPS).
| Materials | Thermal conductivity (W/m·K) | Moisture resistance | Installation |
|---|---|---|---|
| Mineral wool | 0.035 - 0.045 | Requires waterproofing | Difficult (framework) |
| Foam (PSB) | 0.035 - 0.040 | Tall. | Simple (glue) |
| EPPS | 0.028 - 0.034 | Very high. | Simple (glue/dowels) |
| polyurethane | 0.020 - 0.030 | Absolute. | Professional |
When installing the insulation, it is important to ensure a ventilation gap between the insulator and the metal wall. This will allow moisture to evaporate without destroying the structure of the material. For fastening plate materials to the metal use a special glue foam or plate dowels. All joints must be glued with foil tape.
Interior decoration and organization of space
The interior of the garage should be not only beautiful, but also functional. Walls are often sheathed SWApstick or moisture-resistant drywall, which allows you to hide communications and insulation. The surface of the plates can be painted with washable paint, creating a light and neat space. Light colors visually expand the space and improve lighting.
- 📦 Installation of shelves and shelves along the walls for storing tires and spare parts.
- 💡 Installation of LED lighting with separate zones for the working area and observation pit.
- 🛡️ Protection of the lower perimeter of the walls with rubber tape or metal corner.
The floor in the garage also needs attention. The concrete screed is better covered polyurethane or special paint for industrial floors. This will prevent the dusting of concrete and make it easier to clean from oils and fuels. In the working area, you can lay a modular PVC tile that withstands high loads.
☑️ Checklist of interior decoration
Protection of gates and locking mechanisms
Garage doors are subjected to the greatest mechanical and atmospheric load. Loops and locks should be regularly lubricated and protected from moisture. When painting the gate, use a thicker layer. corrosion-infoilThis element is most often in contact with the external environment.
If the gate is equipped with a gate, check the density of the seals on the perimeter. Rubber seals dry up over time and require replacement. To improve the thermal insulation can be installed heatscreen Or a vestibule, if the design permits.
⚠️ Warning: Do not paint over the working surfaces of locks and hinges, this will lead to their jamming and breakage of the mechanism.
For metal gates, hammer enamels are excellent, which hide small irregularities and create a textured surface. This paint is less susceptible to chipping in accidental impacts. It should be applied in two layers with intermediate drying according to the manufacturer's instructions.
Ventilation and microclimate in the garage
Proper design of the iron garage necessarily includes the organization of ventilation system. Metal structures are prone to condensation due to temperature changes. No fresh air inflow humidity It will quickly reach critical values, which is dangerous for the car.
It is enough to install supply valves in the lower part of the walls and exhaust channels in the upper part or on the roof. Natural traction will ensure a constant exchange of air. In winter, you can use heat recovery devices to avoid cooling the room.
Calculation of ventilation power
For a 20 sq.m. garage. air exchange of at least 180 cubic meters per hour (3 volume of the room) is required.
Humidity can be controlled using a hygrometer. If the indicators exceed 60-70%, it is necessary to increase ventilation or use dehumidifiers. Dry air is the key to a long life as the garage itself and the transport stored in it.
Budgeting and cost of work
The financial side of the issue plays an important role in deciding how to arrange an iron garage. The cost of materials varies widely. Budget painting will be cheaper than siding with insulation. However, long-term repair costs can offset the initial savings.
When compiling an estimate, take into account the cost of consumables: brushes, rollers, solvents, fasteners. Don't skimp on it. primer The main protective compositions, as they are the foundation of the entire coating. Cheap paint may require updating in a year, while quality paint will last 5-7 years.
Buy materials in late autumn or winter, when construction stores often hold seasonal sales.
If you are planning to hire contractors, ask for several estimates from different teams. Make sure that the cost includes preparatory work, which often accounts for up to 40% of the total labor. Independent implementation of part of the work (dismantling, cleaning) will significantly reduce costs.
Do I need to remove the old paint completely?
If the old coating is swelled and flaked, it must be removed completely to the metal. If the paint is held firmly, it is enough to clean the damaged areas and matt the surface with an abrasive to improve the adhesion of the new layer.
Can I insulate the garage with foam?
Yes, you can, but it is important to choose high-density brands and be sure to protect them from rodents with a metal mesh or plaster. It is also a fuel foam, so it requires careful handling near heating sources.
How often should I update my metal garage?
When using high-quality materials and proper surface preparation, repainting is required after 5-7 years. Visual inspection once a year will help to notice small defects in time and paint them locally.
