Paint Booths for Wood Finishing: What You Need to Know

While most spray booths operate in similar ways, there are some characteristics that make certain models better for specific tasks. Woodworking spray booths are specifically designed to enhance the finishing process for wood items, including furniture and art pieces. These specialized spray booths offer many advantages, making the finishing process better, safer, and more efficient.

Spray Booths and Wood Finishing

In general, a paint booth provides a place to apply finishes to three-dimensional objects. In the field of woodworking, different projects may require unique finishes and coatings:

  • Stain
  • Paint
  • Sealer
  • Primer
  • Glaze
  • Powder coating (for MDF)
  • Lacquer
  • Varnish

Woodworking paint booths are designed to make it easier to finish wood items, improving the final appearance and condition.

Benefits of a Woodworking Spray Booth

A paint booth provides a favorable environment for the wood-finishing process. There are several advantages a specialized spray booth provides in a woodworking shop:

  • Better lighting, which can allow the operator to identify and fix issues with the finish
  • Proper ventilation, which can improve the overall air quality in the shop
  • Upgraded safety measures, which can help mitigate fire risks
  • Filtered exhaust mechanisms, which can reduce overspray and air pressure problems

Finishing furniture and other wood products is safer and faster with a paint booth that’s customized for woodworking.

Types of Woodworking Paint Booths

Spray booths for wood finishing are available in different configurations, but there are two styles that are the most common: enclosed and open face. Each type has unique benefits and challenges that render it better for certain shops and projects.

Enclosed Paint Booths

In general, enclosed spray booths take up more space in a shop than open face models. You must allow space for all four sides of the booth plus additional room for the doors to open. Enclosed paint booths also tend to be more expensive. However, this design makes it far easier to reduce contaminants that can degrade the quality of the finish. With an enclosed booth, it can be easier to control the air pressure and the airflow style and, in turn, the finish quality.

Open Face Paint Booths

As the name implies, an open face spray booth usually has three walls and a ceiling, with the fourth side being open to the rest of the shop. This style is generally more affordable than an enclosed model and may take up less floor space. Some open face booths are wider than they are deep (the opposite of many enclosed models), which may be better for some woodworking projects such as finishing cabinet doors. However, the open nature of this type of spray booth makes is more difficult to eliminate the contaminants that can negatively affect the finish.

Considerations When Choosing a Paint Booth

When you’re ready to upgrade the functionality of your woodworking shop with a spray booth, there are several things to consider. As discussed above, one of the most important aspects to decide on is whether you want an open face or enclosed model. There are other essential factors:

  • Size
  • Exhaust infrastructure
  • Fans and ductwork
  • ETL certification

The specifications of your shop may limit your options to booths of a specific size and/or exhaust structure. Your local laws may require you to purchase an ETL-certified model, or you may choose to do so for the added safety benefits.

Upgrade Your Shop with a Woodworking Spray Booth

The right paint booth can simplify the finishing process for countless types of wood items. Whether you are making wood furniture or crafting wood art pieces, you can count on a gorgeous finish when you use a specialized woodworking spray booth.

We offer a variety of spray booths designed for wood finishing, including both open face and enclosed models. ETL-listed booths are available, and we can also develop and manufacture a customized solution based on your unique requirements. Contact our team to learn more about our woodworking paint booth options.

ETL Certification: What Is It and Why Is It Important?

When you are choosing a paint booth, one thing you need to consider is ETL certification. Spray booths with this certification have been rigorously tested and verified to comply with certain safety codes. Some state and local regulations may require you to install an ETL-certified model. The ETL Mark can give you peace of mind that your paint booth meets the highest safety standards and won’t give you any issues with local authorities.

ETL Certification and OSHA

ETL stands for Electrical Testing Laboratories, and it’s an organization that tests the safety of products and electronic components based on a set of rigid standards. While this company has been around for over 100 years (it was started by Thomas Edison), it now functions as a division of Intertek Testing Laboratories. Intertek ETL is a Nationally Recognized Testing Laboratory acknowledged by the U.S. Occupational Safety and Health Administration.

Paint Booth Compliance with Safety Codes

Intertek tests products based on North American safety standards and applies the ETL Mark to products and components that meet compliance requirements. One relevant safety code for paint booths is NFPA-33, which is the National Fire Protection Association’s standard for spray application using flammable or combustible materials. An ETL Mark on a paint booth indicates that Intertek finds it in compliance with NFPA-33 standards.

Another element of ETL testing for a paint booth covers the electrical control panel that operates the fans and lights. The relevant safety codes for a control panel are C 22.2 No. 14 and UL-508A. At Standard Tools and Equipment, we are an authorized ETL shop by Intertek for all the control panels we manufacture. We affix the ETL mark to these components prior to shipping them out to you.

Government Requirements and ETL-Listed Paint Booths

There are many advantages to purchasing an ETL-listed paint booth, and you may decide that you want these benefits in your shop. In some cases, however, you may not have a choice; certain state or federal laws may require you to get an ETL-listed booth. There may also be local ordinances or fire codes that necessitate you choosing ETL-listed equipment for your shop.

In general, you may need an ETL-listed paint booth if your shop is in a large city or a state with high safety standards (e.g. WA, CA, OR, MN, RI, CT, MA, and NY). Most government facilities require ETL-listed equipment. Before ordering a paint booth, it’s best to contact your local authorities for information on certification requirements.

Obtaining the ETL Mark for a Paint Booth

There are two ways to obtain an ETL mark for your paint booth: purchase an ETL-listed model or schedule an Intertek inspection and certification after you install an uncertified spray booth. Getting the ETL mark upon purchase can save you a significant amount of time and money.

Standard Tools and Equipment offers several ETL-listed models that include the following:

  • An air valve solenoid that interlocks the spray equipment and the fan motor
  • An electrical control panel that is ETL-listed
  • An official ETL certification label on the booth

Having the ETL mark on your paint booth can show your clients, employees, and local authorities that you value safety and have taken the necessary precautions.

Selecting the Right ETL-Listed Paint Booth

Whether your local laws require you to get an ETL-listed booth or you simply want the confidence that comes with knowing your booth meets the standards, we can help you choose the right certified paint booth. We have a wide range of ETL-listed models, including semidown, cross flow, and open face options. You can also choose an ETL-listed booth that includes a heated AMU for more control over the finishing process. When you order a booth from Standard Tools that has been certified, it is included in the listed booth’s price. Purchasing an ETL-listed booth is far more cost-efficient than requesting a certification inspection after installation should you need it. Our diverse selection of paint booths makes it easy to find the right model for your needs. For additional information on the ETL certification or assistance in choosing a paint booth, contact our team at 888-312-7488.

Paint Booth Operations: 4 Reasons Why Proper Airflow is Essential

No matter what type of paint booth you have, you want it to perform optimally. There are many things that can affect a spray booth’s operational capability, but one of the most important is airflow.

Maintaining proper airflow can ensure your booth creates perfect finishes and operates within acceptable safety parameters. On the other hand, airflow problems can compromise the booth’s efficiency, performance, and longevity. Understanding the basics of airflow and the methods for controlling it can help you operate your paint booth safely and effectively.

1. Finish Quality

Airflow within your paint booth can have a significant effect on the overall finish of whatever you are painting. Adequate, balanced airflow helps ensure the paint sprays uniformly and dries quickly. However, incorrect airflow may cause several problems:

  • Incomplete or uneven drying
  • Non-uniform finish
  • Introduction of dust and debris within the booth

Even small variances in airflow can cause problems with the finish on your project, and in some cases, you may have to repaint the object entirely. Controlling the airflow within your paint booth is essential for a high-quality finish.

2. Overspray Management

The overspray in a paint booth can cause significant issues if it’s not handled properly. The paint booth needs to direct the overspray away from the object being painted so as not to ruin the finish.

However, the overspray can’t just be pulled out of the booth and released into the shop; that could compromise the air quality and create a dangerous working environment for your operators. The overspray must be directed to air filters that are designed to capture it safely. It’s vital to replace clogged air filters immediately. If you continue to run a paint booth with clogged filters, it could unbalance the air pressure, forcing the overspray into the shop’s air.

3. Air Pressure Balance

Safe, effective spray booth operation requires proper air pressure within the booth, and managing airflow is the key to maintaining the correct pressure. During operation, exhausted air is removed from the booth, which can create negative air pressure. The easiest way to resolve this issue is to install an air makeup unit that replaces the exhausted air at the correct rate to balance the air pressure within the booth. A heated AMU is especially useful, as it can provide warm replacement air to speed up the curing process.

In most spray booths, there are two types of fans that manage the airflow. The exhaust fan pulls used air from the booth toward the ductwork and removes the overspray so it doesn’t affect the finish quality. An AMU uses a blower fan to push replacement air into the booth. Controlling the airflow with these fans allows you to maintain the correct air pressure inside the booth.

4. Safety

Ensuring proper airflow is a vital element of safe paint booth operation. The Occupational Safety and Health Administration and the National Fire Protection Association even have specific requirements for air velocity within paint booths.

Adequate airflow helps reduce the risk of fire by lowering the concentration of flammable materials in the booth’s air. The exact nature and direction of the airflow within a spray booth vary depending on the design:

No matter what type of paint booth you choose, it’s essential to ensure compliance with OSHA and NFPA airflow requirements.

Maintaining Proper Airflow for Optimal Performance

Proper airflow is a vital aspect of safe and effective paint booth operation. While the exact airflow requirements and directional patterns depend on the type of spray booth, federal safety guidelines define the appropriate parameters. Several things can impact the airflow and air pressure within your booth: clogged filters, malfunctioning fans, and inadequate AMU performance. If you aren’t sure whether your spray booth is maintaining adequate airflow, we can help you figure out the next step.

Industrial ETL-Listed Open-Faced Booth: Painting Tanks!

“The paint booth [open faced booth] has been fantastic. The amount of time it saves us and the result of increased production it has paid for itself. Plus, the fact that our spray guns are wired through the booth so they cannot work without the fans on for safety purposes.”

Open face booth photo

Cramer Decker is a global leader in the development and delivery of innovative life support technologies and gas management solutions, according to their web site.

They ordered our open face booth for their facilities in California. They use it in the industrial application of coating tanks. They ship the tanks out empty, to be eventually filled by their customers with gases like oxygen, nitrogen or argon.

They have an ETL-certified 20′ wide open-faced booth (OFB-20). With the ETL-listing the booth also received the Standard Tools control panel for operating the lights and fan.

The open-faced design draws air into the booth through the open front, which is then exhausted through the back wall filters. The open front makes it easy to load the tanks and spray them. This application is also great for furniture, cabinets, bulky equipment or small equipment. It is like our paint wall, but with an “awning” of lights and some side walls to contain the over-spray.

Our open face booths come in a variety of widths to fit every application! Whether you’re painting furniture, parts and pieces or tanks… we have a booth for that.

Industrial Paint Wall For Flawless Chrome Detail

A passion for car restoration turns into a major business of unique pieces.

I recently had the pleasure to work with and get to know Mr. Donald Pirre when he purchased an Industrial Paint Wall for his company, Coat of Chrome. He told me that he “chromes” anything, and I was intrigued. Don is not just a “chromer” (is that a word?) … but he is a true artist and master of his trade. Can you really chrome anything? Let’s see.

20151118_125304Coat of Chrome was born out of his passion for restoring classic antique vehicles. His award winning automobiles include a 1967 Chevelle Malibu convertible and a 1967 Chevelle SS convertible. He discovered that it was a challenge to re-chrome parts due to the expense as well as the lack of service providers.

Don learned of a process used in Canada and Europe, which was not only effective for his auto restoration but also for numerous other applications. He went to Canada and learned from the experts and came back to open his business in 2003. Coat of Chrome can coat any type of material (metal, wood, glass, plastic, stone, fiberglass, ceramic, even fabric, etc.) with a mirror-finish, silver-metal coating that exactly duplicates chrome plating or colored chrome finishes.

NESHAP Standards & Your Paint Booth

What you need to know about NESHAP requirements before you buy your spray booth.

Do you remember that movie, based on a true story, Erin Brockovich? Julie Roberts won an Oscar for her portrayal of the real-life environmentalist that went after a power company in Texas after contaminating the drinking water and caused many health issues in the community? That’s what I think of when I think of the National Emission Standards for Hazardous Air Pollutants (NESHAP).

The goal is to reduce hazardous air pollutants (HAPs), which are pollutants that are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects. HAPs are also known to cause adverse environmental effects.

Clean Air Act

Americans are breathing easier and living healthier lives since the Clean Air Act was enacted in 1970. The EPA has made the reduction of HAPs a priority since the Clean Air Act Amendments of 1990. It’s important if you are working with these pollutants, you follow the rules of compliance for working safely. The National Emission Standards for Hazardous Air Pollutants (NESHAP) were developed in the 1970 (Clean Air Act – CAA) for hazardous air pollutants and revisited / enforced in the Clean Air Act Amendments of 1990.

First & Before: If you are looking to buy a booth, we always recommend that you speak with your local officials first to find out what is required. You’ll thank us later when you’re not paying to “get compliant”. This will vary based on where you are, what your spraying, etc. Your fire marshal can give you the city’s requirements, like if your booth needs to be ETL-listed (which we have), but you should also contact your local EPA office to see if you will be required to meet NESHAP requirements as well. It’s a good idea to have all your permits in place before you buy your booth. Read our blog to see all Top 10 Things you need to consider before buying a paint booth.

Know what you’re spraying. Do you know what you’re spraying? Have you read the labels and made yourself familiar with what all those ingredients are? Do you have the proper protective gear and equipment for you and your staff, to protect their health and safety?

If you are required to follow the NESHAP guidelines, here are some of the regulations by the EPA that you need to know:

  • Spray booths used to refinish complete motor vehicles or mobile equipment must be fully enclosed and ventilated at negative pressure or up to 0.05 inches water gauge positive pressure for booths that have seals on all doors and other openings and an automatic pressure balancing system.
  • Spray booths used to coat miscellaneous parts or products or vehicle sub-assemblies must have a full roof, at least three complete walls or side curtains, and ventilated so that air is drawn into the booth.
  • Spray-applied coatings must be applied with a high-volume, low pressure (HVLP) spray gun, electrostatic application, airless or air-assisted airless spray gun, or an equivalent technology.
  • Paint spray gun cleaning must be done so that an atomized mist or spray of the cleaning solvent is not created outside a container that collects used gun cleaning solvent.
  • Train and certify all personnel who spray apply surface coatings no later than 180 days after hiring.
  • Install/operate filter technologies on all spray booths to achieve at least 98% capture efficiency.

NESHAP sanding booth with two MERV 11 filter boxes for recirculated air.

That last one, about the correct filtration, can be a bit tricky to understand if you’re not a “filter expert”. So, we consulted our filter experts about it and came up with the solution.

We can now provide you with a booth that has been designed for three- or two-stage NESHAP filtration. If it is two-stage, it means that your overspray will pass through 2 different filters before it is exhausted. If it is three-stage filtration, it will go through… you guessed it, three different filters. This is to ensure that the air is properly filtered of all contaminates before exhausted.

The booth will have a larger-than-normal fan to pull the air through multiple filters and there will be a “set” of different types of filters, based on your needs for compliance. The blanket filter pads, pocket filters, MERV 11 Filters and more are stacked to fit you needs. We choose filters with the efficiency you need to meet the 98% capture requirement.

We’re here to help you figure it out and get you setup to be successful, compliant, and safe. We don’t want Erin Brockovich coming after you next. Give us a call.

NEW! Heated Full Downdraft Booth.

We have designed a heated downdraft full-sized paint booth. The downdraft paint booth supplies filtered air to the booth through the full-filtered ceiling, and exhaust the chemical-containing air through filters below the grating on the floor. The air is directed downward, and the paint vapors and overspray are carried downward. So, the toxins do not pass by the painter’s breathing zone. This design is built for a pitted exhaust system. Although we provide the grating and the floor filters, we do not include the installation of the actual pit.

Since this booth is heated, the intake air is passes over the Sure-Cure direct-fired air make up unit (AMU) before it is pushed down through a full-plenum filtered ceiling.

DDGrateFloor-7filters-500
Booth Shown: DD-1000GH, with Powder-Coating finish, LED Flat Panel Lights, Floor covering.

We provide the booth, the Sure-Cure air makeup unit, the floor grates and filters for your downdraft paint booth. We are the manufacturer and can customize your booth to fit your needs. So, if you want to add lights, have double drive-thru doors or make your booth taller, just give us a call for a custom-designed booth. Continue reading NEW! Heated Full Downdraft Booth.
