The garage has long ceased to be just a concrete box for storing a car. Today it is a multifunctional space where not only equipment is repaired, but also workshops, recreation areas or storage areas are set up. However, the issue of saving during construction and repairs is always acute, because investments in real estate should not exceed reasonable limits, especially when it comes to an auxiliary structure.
The choice of materials for interior decoration directly depends on climatic conditions, frequency of use of the room and the financial capabilities of the owner. Budget finishing does not mean using low-quality solutions; on the contrary, a competent approach allows you to create a durable and aesthetic coating at minimal cost. It is important to consider fire safety and resistance to mechanical damage.
In this article we will look at the main cladding options that will allow you to get excellent results without overpaying for brands and frills. You will learn about the pros and cons of popular materials, and also receive practical recommendations for their installation. The right choice is a balance between cost, durability and functionality.
Before purchasing materials, it is necessary to conduct an audit of the condition of the walls and ceiling. If there are serious differences in heights or defects, part of the budget will have to be allocated for preparatory work. Plastering or sheathing with a frame will hide the unevenness, but will require different investments. Ignoring preparation can ruin all your finishing efforts.
Plaster: a classic and reliable option
The most common method of finishing garage walls is plastering. This is a traditional method that allows you to level the surface and create a solid base for further painting. Modern mixtures have improved characteristics, making them an excellent choice for unheated rooms.
For garages, cement-sand mortars or gypsum-based plasters with additives are most often used. Cement mixtures are more resistant to moisture and temperature changes, which is critical for garage conditions. Gypsum compounds are easier to apply, but require a dry microclimate, otherwise they may deteriorate over time.
The process of applying plaster requires certain skills, but it can be mastered if desired. First, the surface is cleaned of dust and dirt, then a layer of primer is applied to improve adhesion. After this, beacons are installed and the solution is poured, leveling it with the rule.
⚠️ Attention: When working with cement mortars, be sure to use a respirator and safety glasses. Dust from dry mixtures and splashes of alkaline solutions can seriously damage the mucous membrane of the eyes and respiratory tract.
After drying, the plaster can be painted with water-based or facade paint. This will give the room a neat look and make cleaning easier. It is better to choose washable paint so that you can remove dirt with a damp cloth.
To increase the strength of the plaster layer in the garage, add a small amount of PVA glue to the solution or use a special reinforcing mesh, especially in corners and joints.
The main advantage of plaster is its solidity and fire safety. Unlike sheet materials, there are no voids where rodents could live. Moreover, it is one of the most economical ways straighten curved walls made of foam block or brick.
Cladding with clapboard and imitation timber
Wooden lining or its MDF and plastic counterparts are a popular choice for those who want to create a cozy atmosphere in the garage. Natural wood looks aesthetically pleasing, retains heat well and creates a pleasant microclimate. However, it is worth remembering fire safety when using flammable materials.
Plastic lining (PVC) is a cheaper analogue of wood. It is not afraid of moisture, is easy to clean and does not require additional treatment with antiseptics. For a garage, this can be a great solution, especially if the room is often cleaned using water.
Installation of the lining is carried out on a wooden sheathing. This allows you to hide communications and lay insulation between the frame slats. Lathing also helps to level walls without using wet processes.
- 🌲 Natural lining creates a unique microclimate and a pleasant smell of wood.
- 💧 Plastic (PVC) is absolutely moisture resistant and does not rot even in damp garages.
- 🔥 Wooden panels require mandatory treatment with fire and bioprotective compounds.
- 🔨 Installation of the lining allows you to easily dismantle the trim for access to the walls.
When choosing wooden lining, pay attention to the class of the material. For a garage, class “B” or “C” is quite suitable, which has more knots and defects, but is much cheaper than premium grades. The appearance can be improved with tinting.
Secrets of saving on lining
Buy lining 1-2 meters long (offcuts) - it costs 30-40% less than long slats. For a garage with a lot of furniture and equipment, short slats will not be noticeable.
It is important to consider that wood is a living material. It can respond to changes in humidity by expanding or shrinking. Therefore, during installation, leave small compensation gaps at the floor and ceiling.
OSB boards and plywood: fast and practical
Oriented strand boards (OSB or OSB) and plywood are materials that allow you to quickly cover large areas. They are durable, relatively inexpensive and easy to install on a frame. OSB-3 or OSB-4 have increased moisture resistance, which makes them suitable for garage conditions.
Plywood, especially birch plywood, is stronger than particle boards, but also more expensive. It has a smoother surface that can be coated with varnish or paint. However, for garages, low-grade unsanded plywood is often used, which is then painted.
The slabs are installed on a wooden or metal frame. The sheets are fastened with self-tapping screws, and the joints are puttied. The surface of the slabs does not need to be further finished, leaving them in their natural form, which is now even fashionable in the loft style.
⚠️ Attention: Cheap types of OSB and plywood can emit formaldehyde. For interior work, use only materials with an emission class of at least E1 or E0 to avoid harm to health.
One of the advantages of this finish is the ability to easily mount shelves, hooks and tool panels anywhere on the walls. The slab can withstand significant loads, which is important for workshop in the garage.
If you are planning insulation, then the space between the frame posts is filled with mineral wool or polystyrene foam. OSB boards perfectly protect the insulation and create a rigid shell of the room.
Siding and corrugated sheets for interior decoration
Using siding or corrugated sheets inside a garage is a non-standard, but practical solution. Metal sheets are durable and resistant to fire, water and rodents. They are ideal for garages where fuels and lubricants are stored or welding work is carried out.
Siding (vinyl or metal) is easy to install and comes in many color options. It does not require painting or special care. Corrugated sheeting creates a strict industrial look and is characterized by high mechanical strength.
Both materials are fastened to the lathing. This allows you to hide uneven walls and lay communications. Metal surfaces are easy to clean, which is important for a garage where it is often dirty.
However, metal also has disadvantages. It “rings” when struck and can condense moisture on the inner surface during sudden temperature changes. Therefore, high-quality insulation and ventilation play a key role here.
| Material | Strength | Moisture resistance | Price | Difficulty of installation |
|---|---|---|---|---|
| Plaster | High | Average | Low | High |
| PVC lining | Low | High | Low | Low |
| OSB boards | Average | Average | Average | Average |
| Corrugated sheet | High | High | Average | Low |
When choosing a metal finish, make sure that the edges of the sheets are finished to avoid cutting during use. It is also recommended to use sealing tapes during installation to avoid metal rattling.
Ceiling in the garage: how and how to finish it
Finishing the ceiling in the garage is often left in last place, but this is a mistake. A properly designed ceiling improves illumination and protects against dust falling from the roof or ceilings. The same materials are suitable for the ceiling as for the walls, but taking into account the weight.
The simplest and cheapest option is whitewashing or painting with water-based paint directly on concrete or plaster. This visually increases the height of the room and makes it brighter. However, such a ceiling will not hide wiring and pipes.
If it is necessary to hide communications, use suspended ceilings made of plasterboard (moisture-resistant plasterboard) or plastic panels. Drywall requires puttying and painting, but gives a perfectly flat surface. Plastic is installed faster and is not afraid of leaks.
☑️ Ceiling finishing plan
When installing the ceiling, it is important to provide places for mounting lamps. Spotlights or LED strips, it is better to plan in advance so as not to drill into the finished structure.
Don't forget about ventilation. Exhaust gases and gasoline vapors, which are lighter than air and rise upward, often accumulate in the garage. The presence of an exhaust vent in the ceiling area is mandatory for safety.
Insulation and waterproofing: is it necessary?
Garage finishing is often combined with its insulation. If you plan to spend time in the garage during the winter or store temperature-sensitive materials there, insulation is essential. Without it, any finishing will be less effective.
To insulate walls and ceilings, mineral wool, polystyrene foam or expanded polystyrene are used. Mineral wool does not burn, but is afraid of moisture. Styrofoam is cheap and moisture resistant, but it is flammable and may be attractive to rodents. The choice depends on priorities: safety or price.
Waterproofing is especially important for garages that are low-lying or have groundwater problems. Before installing finishing materials, the walls should be treated with penetrating waterproofing compounds.
⚠️ Attention: Never cover the insulation with vapor barrier film on both sides! Steam must be able to escape, otherwise condensation will form inside the structure, which will lead to rotting.
The correct “pie” of a wall looks like this: wall, insulation, windproof membrane (if necessary), lathing, finishing material. Compliance with technology will extend the service life of the entire structure.
The main purpose of insulating a garage is not so much heating as preventing the formation of condensation, which destroys the car and tools.
FAQ: Frequently asked questions
Can drywall be used in an unheated garage?
Ordinary drywall (gypsum board) is not suitable, as it is afraid of moisture and can collapse when frozen. Use only green moisture-resistant drywall (GKLV), but even this requires good ventilation and no direct water leaks.
What is the best way to paint the walls in the garage?
The best choice is acrylic or latex paints for facade work. They are elastic, resistant to abrasion and temperature changes. Rubber paints are also popular, creating a durable matte finish.
Do I need to prime the walls before gluing tiles or plastering?
Yes, primer is required. It removes dust from the surface, reduces the absorption of the base and improves the adhesion of finishing materials. Without primer, the plaster or adhesive may peel off.
What is the minimum temperature that garage trim can withstand?
Most modern materials (plaster, paint, siding) are designed for a wide temperature range from -40°C to +40°C. Problems can only arise when sudden changes and high humidity cause condensation.
