Why should you buy a Spray Booth?

Spray paint booths represent one of the greatest strides made toward cost-effective productivity in modern manufacturing. They have been designed to accommodate almost any manufactured item, from the smallest plastic components and intricate furniture to the largest semi trucks and assembly lines.

In addition to streamlining production, they also provide critical safety for workers and the surrounding environment, controlling hazardous materials to prevent spills, contamination, and many health-related issues.

It must be also taken into account that during the last decades, most of the needs in the refinishing sector have changed. The following table can compare the main changes between those different eras:

based paints.

A wide range of laws and guidelines have been established to ensure safety for people and the surrounding environment. Much of this is due to the high level of toxicity and flammability related to the sprays, paints, adhesives, and finishing solutions used within a spray operation.

Proper assembly, ventilation, and wiring are necessary to prevent injury to workers resulting from airborne particles. In the same way, explosions can occur when fumes build up near an open flame. If, on the off chance, an employee uses a space heater too close to the work space or within an enclosed area that isn't properly ventilated, there is a very real risk of explosion.

A professional installation will ensure the booth is situated properly within your shop and assembled correctly to avoid all the mentioned issues.

A wide range of imperfections may occur if not treated well inside a spray booth. With this document we will try to list the most important of them:

WATER BLISTERS ON SURFACESmall blisters on the surface of the paint that can be seen once it dries.Caused by: Humidity inthe air, moisture absorbed by the substrate, condensation due to sudden changes in temperature, application in wet environment, debris on the Surface or insufficient drying of the substrate.

LACK OR LOSS OF PAINT ADHERENCEThe paint layer lifts easily like fish scales.Caused by: Incorrect preparation of the painted surface, presenting grease, dust, dirt or moisture. Incorrect surface sanding. Inadequate primer.

ORANGE PEEL OR LOOSENINGRough or granular surface of the paint produced by bad stretching.Caused by: Fast solvents. Low humidity or high temperature in the environment. High viscosity Paint. Painted part was too hot.

CRACKINGSSmall cracks in the paint surface. They can expand to the whole piece.Caused by: Paint was applyed on a humid, or not completely dry layer. Incorrect preparation of the painted Surface

SILICONESSmall circular holes appearing on the paint surface.Caused by: Pollution of the work environment by the use of silicones, aerosols, etc. Traces of oil in the applyed air.

SOLVENT BUBBLES OR BOILINGSSmall circular blisters that appear in the surface layer during the drying process.Caused by: Pollution in the work environment caused by the use of silicones, aerosols, etc. Ambient temperature too high. Short period of evaporation before drying.

WRINKLINGSAreas with wrinkles in the surface of the paint during application or drying.Caused by: Non-uniform drying (excess of thickness, insufficient evaporation time, no suitable catalyst, etc.). Choosed paint notcompatible with the base coat.

BLURRINGSAreas with dullness and a whitish veil.Caused by: High relative humidity in the environment. Lack of air exchange during the drying process at room temperature. Paint layerstoo think.

DIRT, DUST OR PARTICLESDirt or dust depositing on the wet paint and sticking to it.Caused by: Insufficient cleaning of the surface to be painted. Presenceof contaminants or debris in the air.

About Lagos

Spray booths provide a clean environment for the vehicle/piece, protected from dust or particles originated in the working área

Spray booths provide a uniform airflow and a zero turbulence environment. This is important because even if some particles reaches the inside (mostly through workers), the vehicle will be protected by a thick air layer.

The air reaching the spray booth goes through a set of filters to avoid any posible particle from the outside

Temperature (drying) & humidity control through humidifiers and burners enables to achieve optimal results given a specific type of Paint

Moreover, lots of imperfection could be seen instantly thanks to hight brightness LED panels installed inside the booth. This is veryimportant to match paint shades also.

Downdraft spraybooth airflow

Given the optimal environment that creates a spray booth, there could be considerable savings thanks to:

Reduced Paint layer thickness (optimal temperature and humidity)

More uniform Paint layers (optimal temperature and constant airflow)

Better Paint transfer level (zero turbulence environment and right temperature)

Avoiding imperfections and repaintings (clean dust-free environment)

The most important time saving action is performed during the drying stage of the vehicle/piece. Several drying options are available including heating system of high efficiency, with gas-oil, (natural or GLP), gas or direct combustion, for huge booths or IR and UV dryers for smaller pieces. The main advantages of the drying process inside a spray booth are: more fixing of the paint in the substratum, it allows a significant reduction on the emissions of VOCs, due to the evaporation of the volatiles because of the heat, more resistance of the Paint to the impact (mechanical resistance), reduction of the time that the material to be painted stays in the factory, therefore, less time of operational input on site.

There will be also a significant time saving during the application process, because the vehicle surface has a better temperature and retains the paint perfectly.

This is a very important point for most spray booths and one of the main reasons they exist. Most countries have dedicated laws that forces companies that work with hazardous VOCs (Volatile Organic Compounds), to install booths with severe specifications in order to prevent health issues on the workers.

Specifications may vary, but they usually focus on the airflow intensity, lighting, filtration system, etc.

When the painter starts spraying paint towards the vehicle/piece a cloud of hazardous compounds is released in the air and a simple mask is generally not enough to avoid inhaling this substances. Even the simple contact with the skin may result in severe health conditions after prolonged use.

This is why the spray booth through its permanent airflow obtains two different results:

On one hand it creates an air layer that avoids dust particles to reach the treated Surface, and on the on the other hand it neutralizes the VOC cloud and pulls it out through the pit of the booth, avoiding a direct and prolonged exposure on the worker. Normally higher rates of airflow (measured in m3 per hour), means a safer work environment because it translates to more power to neutralize VOCs.

The mentioned risk could also be applied on just mixing paint and not only spraying. Hazardous fumes from chemical reactions are pretty common when performing this job and it is highly advisable to do it inside the spray booth or even better on a dedicated Paint mixing room.

Fire hazard is also reduced thanks to spray booths. It must be know that most paints and solvents are highly flammable and as a result the area where they are used is normally marked ad dangerous for fire hazard.

Even a spray booth won’t neutralize this hazard, but with a correct maintenance it’s a total safe zone to work in. Just change filters when saturated and keep the interior clean.

The potential emissions to atmosphere from spray painting operations are:

Evaporated solvents (as VOCs) from drying of coating formulations, thinners and cleaners

Odours, caused by odorous solvents and VOCs

Toxic compounds, to the extent that solvents, thinners and cleaners are toxic

Coating overspray or ‘carryover’, and

Sanding and blasting dust arising from surface preparation in some activities, such as smash repairing or timber painting.

The filtration system installed in the spray booth, as well as the active carbon layers (optional) may reduce to acceptable levels the emissions to the atmosphere.

Equipos Lagos has also contributed to develop a PCR (product category rule) that is is part of an Environmental Product Declaration (EPD) which is a multi-criteria measurement standard of the environmental performance developed by ENVIRONDEC (Swedish Environmental Research Institute), related to goods and services from a life cycle perspective.

The final objective of an EPD is to reduce the environmental impact associated with the manufacturing activity throughout the supply chain, use phase and the disposal of the product.
