The absolute cheapest wall covering for a garage is Drywall (Gypsum Board) if material cost is your only focus. However, for a durable, DIY-friendly, and utilitarian garage wall that allows you to easily hang tools, Oriented Strand Board (OSB) or Plywood are the most cost-effective overall options.
To finish your garage walls on a budget, install 7/16" OSB (Oriented Strand Board) or cheap wood paneling directly over the studs. This avoids the costly, messy taping and mudding process required for drywall. For a clean, bright, and durable finish, prime the wood and paint it white.
For a durable and budget-friendly garage wall covering, Oriented Strand Board (OSB) or Plywood are the top choices, typically costing under $20 to $30 per 4×8 sheet. They allow you to screw directly into the wall anywhere to hang tools, and they resist accidental impacts far better than basic drywall.
For a garage, drywall alternatives like PVC Wall Panels, OSB (Oriented Strand Board), Plywood, or Slatwall are highly practical choices. These options bypass the mess of mudding and taping while offering major benefits such as impact resistance, heavy-duty hanging capabilities, and superior moisture tolerance.
If you drywall your garage yourself, you'll pay $0.30 to $2 per square foot in materials, depending on the size of your garage, the thickness of the material, and whether you decide to add texture. If you hire a drywalling pro, you'll pay an additional $1.20 to $1.50 per square foot in labor fees.
You'll likely need a permit since this project may require soil grading to avoid drainage issues. Repairing your floor may be more cost-efficient than replacing it if grading is necessary. No permit may be required to hang drywall on exposed wooden wall studs in your garage.
If your garage is prone to humidity or water from melting snow or rain, consider using moisture-resistant drywall. This material, sometimes called green board, has a special paper facing that helps prevent the growth of mold and mildew, protecting your walls from water damage.
An uninsulated garage door is perhaps the biggest culprit for heat loss in your garage, as there is no barrier to slow the heat transfer out of your garage. In order to protect your garage from heat loss, you need a door with insulation.
Plastic paneling is very easy to install, making it an easy drywall alternative to recommend. You can simply screw most plastic paneling into place and you will be able to cover up walls directly. You can put them right over the studs, so it's really convenient overall.
If you want a cheap alternative to drywall, plywood or OSB are the most cost-effective and easiest to install. For a more modern aesthetic without the heavy lifting, PVC interlocking panels or peel-and-stick wall planks eliminate the grueling process of taping, mudding, and sanding.
Plastic films
Films are the most common and lowest-cost type of covering material. The types of film available are polythene (polyethylene), EVA (ethyl vinyl acetate) and PVC (poly-vinyl chloride). With the constant improvements in plastics, these covering materials offer a lot of flexibility and performance options.
OSB and plywood are typically the most affordable alternatives.

If you want to skip the traditional drywall finishing—like mudding, taping, and sanding—the top alternative is PVC wall panels (such as Trusscore Wall&CeilingBoard). They are lightweight, 100% waterproof, snap together, and don't require painting.
If you're going to drywall a garage by yourself the first thing that you'll need to do is buy your materials. You'll need drywall, of course. Drywall comes in sheets and it's a good idea to get extra sheets in case you measure wrong, a piece of drywall is damaged, or an accident happens.
Because they do not use standard grid electricity or conventional electric and gas furnaces, the Amish heat their homes using off-grid, self-reliant methods. The most common systems include wood- or coal-burning stoves, propane and kerosene heaters, and natural airflow home designs.
The majority seem to agree that insulated, unheated garages, should be allowed to breathe. If the garage is heated, you will need a vapor barrier, otherwise you will get frost and mold.
It takes time for your home to warm up and cool down. If you're not sure how long it takes, try turning the heating on about 30 minutes before you need it. You should turn it off 30 minutes before you'll stop needing it.
The cheapest way to finish garage walls depends on your goals. For a raw, functional shop space, painted OSB or plywood is the most cost-effective. If you want a clean, finished look without taping and mudding, pre-primed wall panels or standard un-taped drywall paired with a thick coat of paint are the best budget options.
No, Trusscore is not cheaper than drywall upfront.
For garage walls, satin is generally the best all-around choice, offering a great balance of washability and glare reduction. Semi-gloss is highly durable and the easiest to clean, but its higher shine will highlight wall imperfections (like dents or poorly taped drywall).
If you do the drywalling yourself, the material cost is around $0.30 to $2 per square foot. That equates to roughly $75 to $1,720 in all, based on your garage size, thickness of drywall, and texture addition. If you work with a professional, you will have to throw another $1.20 to $1.50 per square foot for labor.
Extra Strength for Your Walls
Whereas drywall is really more of a finishing touch, plywood actually ties in and provides a structural element to your garage. This becomes especially valuable if you plan on doing a lot of mounting on your walls – for tools, work-stations, or equipment storage.
For most standard garages, the required drywall thickness is 58five-eighths𝟓𝟖-inch for ceilings to prevent sagging and improve fire resistance, and 12one-half𝟏𝟐-inch or 58five-eighths58-inch for walls. Always confirm your local building codes, as specific Type X fire-rated drywall is frequently required depending on your proximity to the home.
