If you paint anything in the past then you must know. That after applying the paint on the walls, floor, and ceiling this is very difficult to remove.

But when you are painting anything it is normal that other surfaces also get painted. Then after completing the work you need to remove it. That will take lots of energy that may be exhausted.

That’s why if you don’t want to waste your energy on something that can be reduced. Then you should take down everything hanging on the garage wall and move everything away from the garage wall.

Also, you need to cover the floor, all the hardware, outlets, and anything that may get painted while working on your garage wall.

When you do this you can complete your work much faster because you don’t need to do anything after drying the paint. I know some of the small works are also left but this will not take much time.


4. Clean The Wall

As you know opening and closing the garage door, again and again, become the cause of having dirt and dust inside the garage.

Also, the garage is the best place to store some chemicals and other things that are harmful. But you need to use it for your project and other things.

So these chemicals also damage the wall and make it worse.

That’s why before applying the paint on the garage wall you need to clean it carefully. So that the paint properly sticks with the surface.

Don’t worry this is not so hard to do, you can use a Shop-Vac or broom to remove the dry crust of the wall. But for deep cleaning, you need to use a large sponge with a mixture of water and a few drops of dishwashing liquid.

Only use it if the garage wall is washable otherwise it will increase your work. So if the wall is not washable then you can use a moist sponge to clean the garage wall.


5. Preparation For The Garage Walls

Preparing for painting the garage wall becomes different according to the type of wall material. Because there are several types of wall materials available in the market.

Usually, they don’t know that they need to follow different steps for their walls.

That’s why they made a mistake by using the following different steps that are not compatible with their walls. So if you want to get rid of this problem then read below.

  • Drywall: In the drywall, you need to fill the chips, dents, cracks, and holes. Also, you need to use sandpaper and try to smooth the surface as much as possible.
  • Wood: Having a wooden garage wall is difficult because this requires multiple rounds of cleaning. So paint can stick with the surface properly.
  • Brick: Usually, brick garage walls need to be clean with a wire brush and borax. Because its surface is harder and is not great to have paint on it.
  • Concrete: This is the most common garage wall that people have. But this requires filling the gaps, cracks properly and clean the surface well.

Prepare your garage wall according to the type of its material. So that you can get the best results.


6. Primer Up The Walls

When it comes to how to paint garage walls properly, primer is a crucial part of it. Because this will ensure better adhesion of the paint on the surface.

So that you don’t need to paint your garage walls again and again. Also, this will increase the paint’s durability and protect it from dirt, dust, and other things.

Usually, the garage is the better place to store things. That’s why it is essential to primer up the walls. All you need is to pour enough primer into the tray and then apply it on the garage walls evenly and entirely.

So that every small crack and gap will cover whether you have or not the drywall.

A better primer will reduce the risk of having damaged the wall. But make sure to start from the top and then slowly come to the bottom. This will get rid of the drops onto the wet surface and make it worse.


7. Start Applying The Paint

When you successfully apply the primer on your garage wall and it dries up properly. Then it’s time to apply the paint on it so that you can complete your work.

This is not hard to paint the wall but this is as simple as you use the undercoat aka primer. First, you need to empty all the paint in a container.

Then mix them with a piece of wooden stick or electric mixer machine. You need to do this carefully so that you can get a better finish. Then you need to dip the hand brush or roller if you want.

Make sure to dip at least 2″ inches into the paint so that it can hold a better amount of paint. Then let the excess paint drip from the brush or roller.

Starting from the top of the wall is a great idea as in primer. Smoothly come down and paint the entire garage wall. Make sure to use the paint evenly on the surface.


8. Must Be Proper Ventilation

Does your garage have proper ventilation? Some paints like the exterior have the highest amount of chemicals. Those are harmful to your health if you stay inside the garage for a long time until it dries up.

But interior paints don’t have too many chemicals and are toxic but have some. That’s why you need proper ventilation.

If you don’t have then make sure to open the garage door so that all the chemicals and toxins can blow away from the garage.

But having the proper ventilation also helps you in the summer and winter season when you are working in your garage.


9. Be Patient

Do you want to apply multiple coats of paint on your garage door? If yes, then this is a great idea but keep in your mind that this will take more than 1 day.

Because usually, paint requires a minimum of 2 to 3 hours for drying. But in my opinion, this is not enough. If you want a better finish you should leave the paint for more than 5 to 6 hours.

Because the better the paint dries, the better it will help you to get a finish for the second coat. So be patient and if you don’t have a ventilation system in the garage.

Then open the garage door or install the big fan inside the garage so that the paint can properly and fastly dry.
