Removing dust, dirt and debris in the spray booth

Keeping dust, dirt, and debris under control, or even eliminating them completely, in the painting booth is a top priority for anyone working in the painting industry. Contaminants can ruin even the best executed work, and obviously, among the contaminants that can cause paint defects are dust and dirt. In fact, according to some analyses, up to 80% of the dirt present in a painting booth is brought in from outside, and preventing this contamination can prevent the headache of having to touch up completed work.

Tips for preventing dust and dirt in the painting booth

Let's take a look at some practical tips for preventing dust and dirt in the painting booth, achieving impeccable results, and optimizing time and resources.

Dirt from outside

As mentioned, much of the dirt present in an environment where paint is applied comes from outside: shoes and tires, but also organic residues such as hair or dry skin, or the operation of mechanical parts or equipment. And often this type of dirt is not visible to the human eye. The solution can be the use of contamination control mats along with other products such as shoe covers and other appropriate PPE, as well as specific products to trap particulates carried by the air, such as sticky mats, dirt traps, films and coatings for booths, and covers for internal and external fans.

Textile fibers

Unfortunately, PPE can lose textile fibers, as can workwear and cleaning cloths. The solution is technical non-woven fabric products with low or no lint.

Processing residues

Many types and kinds of processing residues can enter a painting booth. The only solution to this problem is the use of high-quality filters with a nominal efficiency of over 90%. To learn more, it is necessary to contact the manufacturer of the painting booth and/or their official supplier of painting booth filters.

Processing residues inside the vehicle

The theme is always that of processing residues, but in this case even more specific: sanding or grinding dust may hide and nest inside parts of the vehicle such as doors, hood, trunk, or engine compartment, and contaminate the air later. In addition to using abrasives of the highest quality in terms of processing residue control, it may be useful to have localized suction tools.

Accumulation over time

Despite all the attention paid to the above points, it is inevitable that there will be some accumulation of dust, dirt, and debris in a painting booth over time, even imperceptible and not visible to the human eye. For this reason, it is essential to regularly clean the workspace thoroughly, as well as the surrounding areas and any additional machinery or equipment. A little extra effort that, however, reduces many problems later.

Disregarding suction systems

Different suction systems, or their peculiar configuration, may require following a certain work process to avoid overspray or other paint defects. Therefore, it is always good to read, know, and remember the manufacturer's instructions for the booth.

Filters that are no longer efficient

The filters in a painting booth have very stringent specifications regarding their filtering capacity over time. Extending their use, without replacing them when required, reduces their filtering efficiency, resulting in contaminated workspace and paint defects.
