How to Build a Paint Booth

homemade boothFor around $200 in materials, anyone with some basic construction skills can create a paint booth. Isn’t that scary? There are hundreds of sites and discussion boards online giving tips on how to build a homemade paint booth, and no two are the same. When looking into building your own homemade paint booth, just whom are you getting advice from? Do they know anything about the proper flow, safety, and design of a paint booth or are they just really crafty?

There are really only two methods: one too common & one correct.

All too common:

DIYer heads to their local big-box store to buy supplies (plywood, 2x4s, nails, any type of light fixtures, two HVAC fans, HVAC filters and some vinyl sheet for ductwork.)  DIYer cleans out a corner in the shop or garage and builds a booth. No worries about airflow, adequate filtration, egress or other such nonsense.  It may require a couple of attempts to get this part of the project just right.  Once complete, DIYer brags to their buddies about how inexpensive this project really was.  Once painting starts, DIYer leaves a door cracked for ventilation, leaving a high potential for an explosion or a fire. Overspray coats the item (due to poor air flow), the items around the booth (due to poor containment) and the items outside the shop (due to poor filtration).  DIYer dials 911 when the paint-soaked plywood ignites.

 

Correctly Install a Paint BoothSDD WHITE INSIDE

Price comparisons often keep hobbyists from exploring other options and considerations. It is possible to buy a pre-engineered spray booth manufactured in a high-quality shop and based on a proven design.  The booth comes with detailed installation, operation and maintenance manuals as well as experienced professionals available to answer any concerns.  Contractors come on-site to complete the booth’s electrical, fire and ducting systems to ensure the highest safety.  Once a permit-of-occupancy is obtained from your local permitting authorities, you can enjoy the quality and productivity that your new spray booth provides for many years. [Plus, you can get extra work from the first guy after his fire.]

CONVERT YOUR SPRAY BOOTH TO A POWDER COAT BOOTH

DSC_0066Here’s the dilemma. You have a paint spray booth but the cost of painting is too expensive. Higher cost per square foot of coverage, higher labor costs and higher waste management costs.

 

Do you want to switch to the more cost-effective and durable powder coating finish? Why wouldn’t you? It’s easier to apply, applies in one coat and has a wider range of finishes. Problem is, booths should not be used for both finishes and you can’t afford a whole new booth specifically designed for powder coating.

 

Although a new powder coat booth is the ideal, we understand sometimes you’ve got to use what you have. Here’s how you can easily convert your spray booth into a powder coat booth.

·         Change your filter panels from dry arrestors to two-stage filters.

·         Add an after-box to provide third-stage filtration and allow recirculation of exhausted air into the shop.

·         Change out your painting equipment (HVLP or similar spray guns) with powder specialized spray equipment that charges the powder during the feeding process to enhance coating.

Lucky for you, Standard Tools has worked with numerous booth owners who have made this change, and we have done this process in our own shop! We can offer all the items you need to convert your current booth into a powder-coating booth…. filter grids, filters, after-filter box and spray equipment.

 

Not sure if you should use powder coat?  It doesn’t work with every finish or every product being coated, but it may be a good answer for your coating process.  Call us to discuss your conversion needs.  Our Sales team will gladly provide pricing so that you can compare a new powder coat booth with converting the existing spray booth.

Keep Your Paint Booth Safe: The Checklist

To keep your paint booth as safe as possible, there are some simple things you should do to maintain your booth and the safety of those who work in it. To make it easier to remember, try adding all of these items to your calendar based on how often it should occur.

 

  • Clean the booth! It’s no secret that to have a great paint job, you need to work in a clean booth!
    –  Sweep and/or mop the floors daily to keep dust off freshly painted surfaces.
    –  Clean the exhaust plenum by sweeping or vacuuming excessive material buildup.
    –  Sweep or vacuum the outside of the booth every year to remove dirt, dust and spider webs that can be sucked into the booth.

 

  • Clean Filters = Clean Air! Change exhaust filters when the manometer reads 0.5” above the initial differential reading. Note: Exhaust filters should be changed if the material about to be sprayed may react with the materials that have already been sprayed and still remain in the filter. Order your new filter kit now.

–  Change intake filters when they appear dirty or every 100 hours of booth usage.

 

  • Inspect elements of your booth. (You want to turn the power to your booth OFF first).

–  Every six months, you should check the fan belts for cracks and tension. Much like automotive belts, they can harden or glaze, and begin to slip.
–  Light fixtures should not have damaged glass or issues with the wire connections.
–  Ensure positive seals on doors, door latches, door hinges, floor sweeps and door gaskets every three months.
–  Check caulking between seams every three months and fill any gaps or cracks.
–  Inspect ductwork every three months for gaps or excessive buildup.

 

  • Maintain a tidy booth! It is critical that the area inside your booth, and the area surrounding your paint booth is as clean as possible. It needs to be free from excessive materials, especially flammable rags and paper products. It’s a good idea to have at least a 3′ perimeter around the booth in all directions that is clean and maintained.

 

  • Schedule semi-annual inspections on your fire suppression system by contacting your local fire suppression supplier.

 

  • Ongoing training for booth users about safety, cleanliness and incident management that includes fires, explosions, spills and fumes.

 

  • Maintain and replace spray equipment (guns, hoses, filters, dryers) and replace routinely.

 

  • Spray booths should contain no more than one shift of spray material and no materials that will react if mixed.

 

  • Mix rooms should contain less than 120 gallons of material.  Materials should be in covered containers.

 

  • Display signage near booth entrances that communicates no smoking, sparks or flames within 20-ft of the booth.

 

  • Contact the experienced team at Standard Tools and Equipment for more helpful tips and information about equipment involved in the finishing process. 1-888-312-7488.
