Now, the question stands: how to touch up paint that was sprayed on?

Well, touch-up paint comes in three forms: aerosol, brush-on, and paint pens. Each kind has a specific application scenario. Examine the area to be covered before deciding on an application strategy. But, you need to plan ahead of time and put some thought behind it. Otherwise, all of the work will definitely go down the drain.

We’ve explained all the work in some easy steps. So, read this article till the end.

Things You Should Know Before You Start

There are a lot of things you need to be wary of. Let’s check- 

  1. Make sure the surface is clean, dry, grease, and oil-free. You need to use a clean towel to clean the surface. You can use water or mild solvent mix to clean that up. A medium to fine grit sandpaper should be used to dull shiny surfaces. This will guarantee that the touch-up paint sticks properly.
  2. If you’re using an aerosol on a smaller area, mask areas where touch-up paint isn’t wanted. It is possible to use masking tape, paper, or plastic sheeting for covering.
  3. Aluminum foil is also a good masking material. It can be pressed into place to create a watertight seal. 
  4. It’s also vital to keep in mind that touch-up paint is only intended to fix minor scratches and nicks. It’s not designed for vast areas or gouges that are more than a few inches deep.

If you’re still unsure about your chosen touch-up method, try it out on a scrap part or in an inconspicuous place first to see if the results are satisfactory.

The Type Of Methods You Can Go For

There are multiple methods that can help you to go for the perfect touch-up after paint is sprayed on. Those methods are mentioned below: 

Aerosol Touch-Up Paint

Before you get started, don’t forget to shake the aerosol can for a minute!! You can shake it however you like. Whether it’s upside down or rolling left or right. Anything will do.

Tap the bottom of the can a couple of times after mixing.

Remember, if the paint is not shaken thoroughly, the color and gloss may alter.

Now it’s time for spraying. Keep the canister 10 to 12 inches away from where you want to spray. Move slowly left or right as you keep on spraying. This will even out the spray throughout the surface. The paint will have a wet appearance once a smooth, continuous film has been produced.

After spraying, wait 5 minutes to let the paint dry. Between coatings, give the can a good shake. After this, prepare the can for storage once you’ve finished. Then, spray the aerosol upside down until a white gas appears (2 to 3 sec). 

This will clear the valve and prevent jamming or drying out.

Brush-On Touch-Up Paint

Again, shake the bottle for at least 1 minute to ensure that it is tightly closed. 

Then dip the brush as low as you can into the bottle. Don’t let the brush soak up too much paint. Just dip it in once and slowly pull it up from the bottle.

When applying the paint, use smooth strokes and apply light pressure to the brush. This way you will get an even coating throughout the surface.

After the wet paint film has been applied, avoid retouching it with the brush. You should never retouch the paint after it has been set. Usually, it takes about 2 minutes for the paint to set. 

Don’t forget to recap the bottle when you’re done.

Paint Pen Application

After the mixing ball starts to rattle, shake the paint pen for at least one minute. Before shaking, make sure the pen is completely closed.

Remove the cap and push the tip of the pen against an inconspicuous horizontal flat surface a few times to prime it with paint before using it for the first time. The paint will start to pour through the tip and around it.

Continuously pressing the tip, may result in the dispensing of too much paint. The tip should be pushed if more paint is required to cover the area.

Apply the paint in smooth strokes with the tip against the area to be mended. After the paint film has been placed, avoid retouching it with the pen.

Because the tip of the pen will dry out really fast. This will happen when you keep the bottle uncapped. So, don’t forget to tightly seal the cap.

So, recap it again when necessary. If the tip is dried out then dip the tip in thinner. If this does not work, then you need to replace the tip.

It’s critical to avoid repeatedly pressing the tip of a paint pen when doing touch-ups. This could cause more paint than needed. When more paint is needed to cover the area, the tip should be pushed.

Things You Should Be Aware Of

It is normal to face some issues when you are trying to touch up paint. Here are couple of things that can go wrong:  

The Colors Might Not Match

Basically, there was insufficient shaking of the aerosol, bottle, or pen. That’s why this is happening. 

To produce the right color and gloss, the pigments inside must be carefully blended. It’s possible that the finish of your goods has shifted. It’s likely that the color of your original finish has changed.

The Colors Might Appear To Be Hazy Or Flat

Humidity may be causing the color to appear flat or hazy. You’ll have to use it in a less humid environment. It’s possible that the area you’re working on is too warm. Allow the surface to cool after removing it from direct sunshine or heat.

The Surface Appears To Be Streaky

The paint coating thickness is inconsistent, causing the surface to seem streaky. Apply a second coat of paint, making sure it’s as smooth and consistent as possible. The application passes for aerosols have all been done in the same direction. Change the spray pattern as much as possible.


What exactly does it mean to blend?

It’s a technique, basically! You blend two or more colors to give a new form of illusion. 

Can you touch the surface straight after you dry it?

No! Wait a bit as it needs to dry out first. 

Can you fix the imperfections in the spray paint?

Yes! It’s possible to fix the imperfections of spray paint.
