How To Spray Acrylic Enamel Paint On Car? Step By Step Guide

Spraying acrylic enamel paint over a car is a great way to renew your car’s appearance and get a smooth finish. 

Here’s a step-by-step guide to help you get started painting a car.

Tools And Supplies Required To Paint Car With Acrylic Enamel

  • Acrylic enamel paint
  • Reducer
  • Spray gun
  • Air compressor 
  • Respirator 
  • Gloves
  • Safety glasses
  • Clean rags
  • Masking tape
  • Sandpaper

Step 1: Wear Protective Gears

As paint fumes from the spray can spread in the air and may irritate your eyes and nose, I suggest you work in a highly ventilated environment. 

Moreover, don’t forget to wear an oral mask or respirator and goggles for protection. You may also put on gloves to avoid staining your arm.  

Step 2: Preparing Car Surface

Before you start painting, you need to properly prepare the car’s surface. 

This can be done by sanding down any imperfections or rough spots and cleaning the car thoroughly to pull out any dirt or debris. 

You can also mask off any areas you don’t want to be painted.

Step 3: Mixing The Paint With Thinner

Next, you have to mix the acrylic enamel paint according to the manufacturer’s instructions and thin it down properly. Here’s how to thin acrylic enamel auto paint:

In order to thin acrylic enamel auto paint, you will need to use a suitable solvent that is compatible with the paint.

Generally, you can use water, paint thinner, or a reducer for this purpose. It helps to thin down and mix the paint for airbrushing

The general rule of thumb is to take start by mixing the paint and thinner in a 2:1 ratio, meaning two parts paint to one part thinner. 

However, you may need to adjust this ratio based on your requirement of coating thickness and the type of spray gun you’re using. 

I suggest you check out the label and follow the instructions mentioned there to ensure the paint is mixed correctly. 

Step 4: Setting Up The Spray Gun

For DIY car painting, I usually pick up a siphon gun, which is usually considered the best automotive paint gun. 

However, other options are also available on Amazon. You may simply order an acrylic enamel auto-paint kit if you’re a beginner. 

Connect your spray gun to the air compressor using the correct fittings, and adjust the air pressure according to the paint manufacturer’s recommended pressure range. 

When it comes to pressure, most beginners ask, “What PSI should I spray acrylic enamel?” Let me tell you most automotive paints require a pressure of between 30 and 50 PSI.

Adjust the flow rate on your spray gun for a consistent spray pattern. This can usually be done by turning the fluid control knob on the gun.

Test your spray gun on a scrap piece of cardboard or metal to check the spray pattern and make any necessary adjustments to the air pressure or flow rate.

Once you are satisfied with the spray pattern, you are ready to begin painting your car surface.

Step 5: Start Applying Paint On Car Surface

Now you’re ready to spray the paint onto the car. Begin by applying a light, even coat of paint, holding the spray gun about 6 to 8 inches away from the surface. 

Avoid spraying too much paint in one area, as this can cause drips or uneven coverage.

After the first coat has dried, you can apply additional coats of paint to build up the layers and acquire a more even finish. 

Never forget to let each coat dry completely before applying the next one. 

Step 6: Go For Finishing Touches

Once the final coat has dried, you can remove the masking tape and any protective coverings. 

You may also need to do some touch-up work with a polishing compound, wax, or other tools for a glossy finish.

How To Spray Single Stage Acrylic Enamel?

Single-stage acrylic enamel is a type of automotive paint that combines color and clear coat into one product. 

This means that only one coat of paint is needed to get a glossy and durable finish, as opposed to the traditional two-step process of applying a base coat and then a clear coat.

To spray this product, you’ll need the same process of thinning it first. Then fill it into an air gun, followed by applying it over the surface evenly.

How To Spray Wet Acrylic Enamel Paint?

Wet acrylic enamel paint that can be applied through a spray gun or aerosol can is a variant of paint that contains acrylic resins and pigments. 

This water-based paint is renowned for its quick-drying characteristics and long-lasting finish.

For best results, I advise you to adhere to the instructions provided by the manufacturer and utilize the recommended spraying method. 

This could entail administering the paint in successive thin, uniform layers, ensuring each coat is entirely dry before proceeding to the next one.
