How to Finish Bottom of Drywall in Garage: Garage Renovation

Drywall is a great material for creating a clean and polished look for the walls in your garage. To finish off the bottom of the drywall in your garage, you need to add trim or baseboard. 

This trim will create a neat and finished look around the outside of each wall, allowing your space to look much more organized than if left unfinished. 

When selecting trim or baseboard, choose something that will match the style of your home – this can range from minimalistic modern to traditional wood models. You may also want to consider some special features such as soundproofing strips or moisture-resistant materials if you plan on using this area for automotive work. 

Once you have material selected, use a miter saw or hand saw to cut pieces that are slightly longer than the length of each wall. Then attach them securely with either nails or screws into studs behind the drywall, ensuring that they are level and free of gaps between each piece. Once installed, sand any rough edges and caulk any gaps before painting it with an exterior-grade latex paint for long-lasting results!

This can be a tricky task, but with a little patience and attention to detail, you can get the job done quickly and easily.

The first step is to cut the drywall to size. You’ll need to measure the space where the drywall will go and then use a saw to cut it to fit. 

Be sure to wear protective gloves and a dust mask while you’re working with the drywall.

Next, you’ll need to apply adhesive to the back of the drywall. You can use a brush or a roller for this step. 

Once the adhesive is applied, carefully place the drywall into position and press it firmly into place.

Use a utility knife to trim any excess drywall that may be hanging over the edges. Once you’re finished, sand down any rough edges and paint or prime the drywall as desired.

Step by Step Guide to Finishing the Bottom of Drywall in Garage

If you’re renovating your garage, one of the final steps is finishing the bottom of the drywall. Here’s a step-by-step guide to help you get the job done:

  • Cut your drywall to size. You’ll need to cut it so that it fits snugly against the bottom of the garage door opening.
  • Install any trim pieces that you want to use around the bottom of the drywall. This will help to create a finished look and also help to protect the edges of the drywall from damage.
  • Apply a layer of joint compound to the back of the drywall and spread it evenly with a putty knife or trowel.
  • Press the drywall into place against the bottom of the garage door opening and secure it with screws or nails.
  • Tape all of the seams between pieces of drywall using fiberglass tape. Apply joint compound over top of the tape and spread it out evenly. Allow everything to dry completely.
  • Sand down any rough edges or Joint compound that is not smooth. Wipe down the area with a damp cloth to remove any dust before painting or staining.

Tips for Better Outcome

If you’re finishing the bottom of your drywall in your garage, here are a few tips to help you get a better outcome:

  • Use a level when hanging your drywall. This will help ensure that your bottom line is straight.
  • Cut your drywall slightly smaller than the opening you’re working with. This will allow for easy trimming and a clean finished look.
  • When attaching the drywall to the studs, use longer screws than you would normally use. This will help keep the drywall in place during those inevitable bumps and bangs.
  • Use joint compound or filler to fill in any gaps or holes along the bottom edge of the drywall. This will give you a smoother, more professional looking finish.
  • Once everything is dried and sanded smooth, paint or texture as desired.

Troubleshooting Common Problems

If you’re having trouble finishing the bottom of your drywall in your garage, here are a few troubleshooting tips to help you out:

  • Make sure that the area is clean and free of any debris before beginning. Any dirt or debris will make it harder to get a smooth finish.
  • If possible, use a power miter saw to cut the bottom of the drywall so that it’s flush with the rest of the wall. This will give you a straighter edge to work with and make it easier to get a good finish.
  • Be careful not to over-apply joint compound or MudPaint on the edges of the drywall. It’s important to feather out the joint compound so that there’s no risk of it peeling off later.
  • Use a damp sponge to lightly smooth out any imperfections in the joint compound once it’s applied. Allow the joint compound to dry completely before painting or staining over top.


How far should drywall be off the garage floor?

Drywall should be installed at least 3 inches off the garage floor to allow for proper ventilation and allow the bottom of the drywall to properly drain in case of any water leaks.

Should I finish the drywall in my garage?

If you’re planning to finish the bottom of your drywall in your garage, there are a few things to consider before starting the project. First, you’ll need to decide if you want to finish the entire bottom of the drywall or just a portion of it. There are a few benefits to finishing the entire bottom of the drywall. This will give your garage a more polished look and make it easier to keep clean. It will also provide an extra layer of protection against water damage and pests. However, finishing only a portion of the drywall may be sufficient for your needs and can save you time and money.

Once you’ve decided how much of the bottom of the drywall you’ll be finishing, you’ll need to gather some supplies. You’ll need a utility knife, measuring tape, level, straightedge, pencil, landmarking template (if desired), joint compound, 4″ or 6″ drywall knife, drywall screws, drill with screwdriver attachment (or screw gun), and sandpaper. Optional supplies include a second person to help hold things in place and/or mudbringer pads.

After gathering your supplies, determine where you want your finished drywall to start and end. Use a level and straightedge to draw lines on the wall at these points. If you’re only finishing a portion of the bottom of the drywall, be sure to measure so that the cuts are evenly spaced. Use your utility knife to cut along these lines.

What is the finish of garage drywall?

The finish of garage drywall is extremely important in order to create a smooth and professional looking surface. There are many different ways to achieve this, but the most common methods are by using either a sanding sponge or a power sander.

If you choose to use a sanding sponge, be sure to wet it slightly before use so that it does not create too much dust. Work in small sections and always sand with the grain of the wood. Once you have sanded the entire section, wipe it down with a damp cloth to remove any residue.

If you opt for using a power sander, start with a lower grit paper and work your way up to a finer one. Again, work in small sections and go with the grain of the wood. Be very careful not to over-sand as this can damage the drywall. Finish off by wiping down the area with a damp cloth.

How do I protect my garage drywall from water?

If you’re finishing the bottom of your garage drywall, you’ll want to protect it from water damage. There are a few different ways you can do this:

  • Use a waterproof sealant: This will help create a barrier between the drywall and any moisture.
  • Tape the seams: Taping the seams of the drywall will help prevent water from seeping in through any cracks or gaps.
  • Apply a coat of paint: A coat of paint will also help create a barrier against moisture.

What finish is best for interior garage walls?

If you’re finishing the bottom of drywall in your garage, there are a few things to consider in order to choose the best finish. First, think about what function the space will serve. If you’re using the garage as a workshop or for storage, a more durable finish like latex paint or epoxy is a good choice. If you’re using the space for parking your car, a less durable finish like enamel paint is sufficient.

Next, consider the level of traffic in the space. If the garage gets a lot of foot traffic, choose a tougher finish that can withstand wear and tear. If it’s not a high-traffic area, any type of finish will do.

Take into account your budget. A more expensive finish like epoxy will last longer and stand up to more wear and tear than a less expensive option like latex paint. Choose the best option for your needs and budget to get the perfect finish for your garage walls.
