How to paint the garage walls?

Make sure you spackle them first then use a stain block to hide any marks from spackle.

I would suggest rolling on a coat of primer before you paint. It’ll help mask all the different color hues (drywall, joint compound, etc.).

Smooth out rough spots with spackle. Larger holes need more support, so get a roll if drywall mesh and follow directions on the package. After you have it smooth, after sanding, use a product like Kilz before using regular wall paint. Good luck and stay safe!

Sheetrcok mud or "spackle" will fill in those holes no problem. Use a little trowel to fill the holes and lightly sand them after it dries. After that I would use a "wet environment" primer and paint because its a garage.

you can buy putty at the hardware store to patch the holes in the wall, follow directions on the can- use a white paint and it will brighten up your garage more- you will need paint, a roller and extenstion pole and trays here is in info go to Home Depot or any hardware store and they can show you what you need to get started

Sheetrock mud applied with a putty knife will fill your holes. The mud is cheap and can be purchased in a small bucket or powder form that is mixed with water. I recommend the pre-mixed mud. After it drys it needs to be sanded, or you can use a sponge and water to smooth it out. The areas with tape need a coat of mud too. You will need a wider sheetrock knife for that area. Prime the walls with primer (Kilz is good) after smoothing out the mud and letting it dry. Sheetrock really sucks up paint. Paint walls after priming. The effort you spend in preparing the walls will show or not show. It is a garage, so use that as your determination of how much effort you want to spend.

I would do 2 coats of primer, the first one before “mudding”, so that you can see the flaws.

Then, as above, mud & then sand.

As a beginner, I would say “less is more”

meaning put on less mud, so you don’t have to sand off a lot.

Then go back and put a thin coat on the areas that need it and sand again.

Do not prime the areas before sanding, as primer will make them harder to sand.

Use spackle to fill in the holes. If your sheetrock has not been covered, use "mud" on a roller and paint the walls. Then prime the walls with a good gripping, hiding primer such as Kilz or BIN 123. Then I would paint with a semi gloss paint.

You need more sheetrock mud. Apply thin coats and sand with either a damp sponge or fine grit sand paper. Repeat until you have a smooth surface. Then prime with Zinsser 1-2-3. Finally, paint with 2 coats of a good paint like Sherwin Williams. I would suggest you go to their store. The employees there are well trained in helping to make sure you have all the supplies you need. Make sure to measure the area before you go and they will also calculate how much paint you need.

Looks from the pic, you still need to complete the drywall first. As far as paint goes, use a good "Primer/sealer" for first coat. If you get the primer tinted to the same color as the paint, then you may get away with only one more coat, Use a 2" brush for edges and corners, and a roller for the rest.

I agree you should use spackle, and then after sanding the spackled areas smooth, you can paint. There is special garage paint you can use.

Outdoor primer and then paint would work best.

Drywall compound to fill the holes. You will also need to "mud" the paper seams with drywall compound. Just put on enough to cover so you won't have to sand a lot. Prime the walls with primer then paint. Lots of Youtube videos that can help you out.
