How do I apply car paint primer correctly?
It's easy to change the appearance of bodywork by changing the paintwork. But before painting, it is necessary to apply a primer for car paint. To succeed in this task, you need the right equipment and the right information.
Materials and tools
- Paper, tarpaulin or other covering
- Masking tape
- Degreaser
- Fine sandpaper and coarse sandpaper
- Primer
- Goggles and dust mask
- Body filler
- Car wash and cleaning equipment
Step 1: Removing dirt
The very first step is to wash the car to get rid of any dirt or grime. Otherwise, dust, grit or dirt can interfere with the primer and paint. It is also advisable to use a grease or wax remover to get rid of dirt that cannot be washed off with soap or water.
Step 2: Sanding the car
Any holes or hollows that need repairing should be filled with body filler and then sanded down.
The aim is to iron out any imperfections so that you have a flat, smooth area to paint.
Step 3: Allow the car to dry
Step 4: Cover areas not to be painted
Be sure to tape all edges. This is very similar to taping over the moulding when painting a wall. The paper can be peeled off if it extends beyond the edge.
Step 5: Priming
An exterior paint primer should be used as it will be more resistant than interior primers.
First, apply a clear coat of primer, making sure there is good ventilation.
For precautions and safety measures, wear protective goggles and a dust mask to avoid inhaling primer.
Step 6: Re-sanding the car
It may be necessary to re-sand your car after the primer has dried. The application of the primer may cause mounds or hollows in some areas, so these should be smoothed out.
How do you adjust your spray gun to apply the primer?
The gun must be set up to apply the primer correctly. To do this, follow these three steps:
Stage 1: air supply
The compressor must not only build up pressure, it must also be capable of producing sufficient pressure at all times. To do this, the compressor must be set to an output of 90 psi.
You also need to regulate the air pressure in the gun via a small regulator that attaches to the base of your gun.
It is also important to have an air dryer. If there is water or oil in the air lines, this could ruin the job. It is advisable to put one at the end of the gun.
Step 2: Choosing the right cap, nozzle and needle
Step 3: configuration
To carry out the spray test, stick a piece of masking paper on the wall.
- Adjust the pressure at the gun inlet using an air regulator with pressure gauge. To start with, the setting should be 50 psi.
- Do a test on the wall.
