A spray booth plays an important role in the refinishing process, yes you can spray without one but the added benefits of a spray booth make it all the more worthwhile having. Being able to paint jobs quicker and cleaner is the best part while on the other hand remaining compliant and meeting the health and safety requirements.
There are also different types of extraction available with spray booths:
Floor extracted
Rear extracted
Side extracted
The best option is the floor extracted booths. This is due to the airflow that they offer which we will talk about in the level 2 version.
Spray booth walls are often coated, this could be coated using a few different methods:
Tacky coating - a sprayable sticky coating that helps keep dust and dirt down
3M Dirt trap - a fabric style film that is stuck onto the walls that does a similar job to the tacky coating but doesn't need to be sprayed on and doesn't need to be washed off using a jet wash or sponge.
Peelable booth coat - this is a spray on and peel off coating. quick and simple however offers no benefits to dust or dirt control as it dries hard.
Activity: find a picture of each type of extracted booth mentioned above and create a word document with these pictures on and label. Also label the air in and air out.
