To finish garage walls, you will need insulation to regulate temperature, a surface material like drywall or wood to enclose the space, and fasteners. Additional supplies depend on the chosen surface, such as joint compound and tape for drywall, or trim and paint to complete the look.
Both OSB and plywood make highly durable, impact-resistant garage walls that allow you to mount heavy items anywhere. OSB is more affordable and structurally consistent, while plywood is lighter, less prone to moisture damage, and looks more attractive if left unfinished.
Builders leave garage walls unfinished (unpainted and lacking textured joint compound) to keep initial home prices competitive and meet strict fire codes. Finishing a two-car garage can add thousands to the price, and many homeowners prefer to customize their own storage, insulation, or workspace later.
Cost-Effectiveness: Plywood and OSB are often more affordable than other wall materials like fiber cement board or metal panels, making them a budget-friendly option for homeowners looking to upgrade their garage walls without breaking the bank.
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.
Some drywall finishers add a small amount of dish soap (like Dawn) to drywall mud as a workability hack. They do this to act as a surfactant, which reduces the surface tension of the mud.
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.
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.
Satin is the best choice for garage walls. Garages are high-traffic spaces prone to dirt, grease, and scuffs. Satin has a slight gloss that makes it much easier to wipe clean and resists moisture, whereas flat paint absorbs stains and is notoriously difficult to scrub.
If you look at the printing on the board, you'll see a double-sided arrow that says something to the effect "Strength Axis This Way. That direction should be across (perpendicular) to whatever studs or joists it's attached to. So, since studs are vertical, the boards should be mounted horizontally.
Particle Board (Chipboard)
Particleboard is widely used to make furniture, as well as the construction industry as a cheaper alternative to plywood. It's commonly used for shelves, cabinets, and tabletops, as well as subfloors and wall panels.
You can paint directly onto OSB (Oriented Strand Board), but it is highly recommended to use a primer first. Because OSB is highly porous and contains resin and wax, applying paint directly causes the board to soak up an excessive amount of paint and can cause the wood strands to swell.
Homes in areas with high humidity and occasional temperature drops will also experience garage condensation. Combining a vapor barrier with Comfortbatt® insulation will further improve moisture control in the space as it's water and moisture resistant. It does not absorb moisture to maintain its insulating value.
The best material for your interior garage walls depends on your goals, but drywall, plywood/OSB, and PVC/slatwall panels are the top choices. Each excels in different scenarios:
Certain home improvements do increase property taxes, but only when they add permanent value or require a building permit. Room additions, finished basements, new bathrooms, and garages typically trigger reassessments. Cosmetic updates like painting or replacing carpet generally do not.
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.
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.
Drywalling a garage is absolutely worth it if you want to improve fire safety, enhance energy efficiency, or create a clean, usable workspace. However, it can be fragile and makes hanging heavy items difficult, leading many to install Plywood or OSB instead.
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.
Yes, an unheated garage is generally warmer than outside. During the winter, it is typically 10∘F to 30∘F warmer. During the summer, it is usually cooler than the blazing outdoor air.
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.
Taping and mudding drywall bridges the seams between panels, seals screw holes, and covers corners. This process creates a single, solid wall surface that hides imperfections, prevents cracking, and is ready for paint.
Surfaces to avoid with Dawn® Powerwash: Marble countertops, sink basins, and backsplashes. Wood, including unsealed, varnished, stained, or painted wood surfaces & furniture.
Plaster is rarely used in modern construction primarily because drywall (gypsum board) is faster, significantly cheaper, and easier to install. While plaster is highly durable and offers better soundproofing and fire resistance, traditional multi-coat plastering requires highly skilled labor and lengthy drying times, making it inefficient for modern housing demands.
