Step 1: Unbox and Inspect (30 seconds)
Open the carry bag and lay out all components on a clean surface. Your Sewinfla booth package includes: the folded booth body, external blower(s) with power cord, intake ducting, filter panels (fiberglass pre-filters and activated carbon exhaust filters), ground stakes or weight bags, and a repair kit.
Before your first use, do a quick visual inspection: check the fabric for any manufacturing irregularities (Sewinfla QC catches these, but always verify), confirm all zippers operate smoothly, and ensure blower fan blades spin freely. This 30-second check prevents discovering an issue after the booth is inflated and you're ready to spray.
Step 2: Choose and Prepare the Site (30 seconds)
Select a flat, level area at least 3 feet larger than the booth footprint in all directions. The ground should be free of sharp objects, stones, and debris that could puncture the floor. If setting up on concrete or asphalt, sweep thoroughly. If on grass or dirt, remove sticks and rocks, and consider a tarp underneath for additional puncture protection.
Position the booth so the intake side faces upwind and the exhaust side faces downwind, away from neighbors' windows or air intakes. Allow clearance for the blower unit and ducting on the intake side, and at least 10 feet of clearance on the exhaust side for solvent vapor dispersion. If wind exceeds 15 mph, orient the booth so the narrowest face points into the wind to reduce flutter.
Mark your booth corners with bright-colored cones or tape before unfolding. This lets you visualize the footprint on the ground and catch obstructions — low branches, overhead wires, uneven terrain — before you commit to the full unfold. Moving an inflated booth is a pain; moving four cones takes seconds.
Step 3: Unfold the Booth Body (60 seconds)
With the folded booth on the ground, locate the inflation duct collar — this is the fabric tube where the blower duct connects, typically marked with a color-coded band or tag. Position this collar on the side where your blower will sit. Then, unfold the booth by walking the fabric outward from the center, spreading it flat on the ground. Do not drag the fabric — lift and lay to avoid abrasion.
Orient the zipper door to face your workspace or vehicle access point. If you're driving a vehicle into the booth, position the door toward the approach path. The booth floor should lie completely flat with no folds or bunching, especially in the center where you'll be walking and spraying. Bunching creates trip hazards and paint traps.
Step 4: Connect the Blower and Inflate (90 seconds)
Attach the flexible ducting to the blower outlet using the integrated cinch strap or clamp. Connect the other end of the duct to the booth's inflation collar, again securing with the cinch strap. The connection must be tight — air leaks here reduce booth pressure. A loose duct connection can cost you 20–30% of your blower's CFM output.
Plug in the blower and switch it on. The booth will begin to inflate — this takes 30–60 seconds depending on booth size. As it inflates, walk around and guide the fabric walls upward, ensuring they don't snag on anything. Once fully inflated, the walls should be taut with no sagging panels. If a panel sags, check the blower connection for leaks and ensure the exhaust vents aren't blocked or over-opened.
During first inflation, the fabric may emit a slight "new material" odor from the polymer coating. This is normal and dissipates after 15–20 minutes of airflow. For the first use, run the blower for 20 minutes before spraying to fully air out the interior.
Step 5: Install Filters (60 seconds)
Sewinfla booths use a dual-filter system that installs in seconds. The fiberglass pre-filter slides into a pocket or clips into place over the intake blower grille. Ensure the filter covers the entire intake area — no gaps at the edges where unfiltered air could bypass. The activated carbon exhaust filter installs in the exhaust port(s), typically secured with hook-and-loop strips or a zippered filter pocket.
Check that filter arrows (if present) point in the direction of airflow. For the pre-filter, airflow is into the blower. For the carbon filter, airflow is out of the booth. Installing a filter backwards doesn't ruin it, but it reduces efficiency and usable surface area.
Step 6: Check Seals and Secure (30 seconds)
Walk around the fully inflated booth and visually inspect all seams and zippers. Run your hand along major seams — you should feel consistent tension with no flapping fabric. Check the zipper door: it should close smoothly and the zipper flaps should overlap to prevent air leaks. On the bottom perimeter, the floor should be in full contact with the ground with no gaps.
If setting up outdoors, stake down the corner loops or place weight bags (sandbags or water weights) on the interior corner tabs. This prevents the booth from shifting in moderate wind. For indoor use on smooth concrete, the booth's own weight and positive pressure are usually sufficient — but weight bags add safety margin if you're moving vehicles in and out.
Keep a small spray bottle of soapy water in your setup kit. Mist it on the duct connections and filter seals while the blower is running. Bubbles reveal air leaks instantly. Fix leaks with duct tape (temporary) or by re-seating the connection. A leaky duct is the #1 cause of under-pressurized booths.
Takedown: Equally Fast in Reverse
When the job is done, takedown is the reverse sequence. Switch off the blower first. Allow the booth to deflate naturally for 30 seconds. Remove filters — note the pre-filter condition and replace if loaded with overspray. Disconnect ducting. Fold the booth by bringing the sides to the center, then folding in thirds lengthwise before rolling from the end opposite the inflation collar. Rolling from the inflation collar end traps air and makes packing harder.
Store the booth in its carry bag in a cool, dry location. Never fold and store a booth that's damp from condensation or overspray — moisture trapped in the folds can cause mildew and degrade the fabric coating over time. If the booth interior is damp after use, run the blower for 5 minutes with the door open to dry it before packing.
Key Takeaways
- Unbox and inspect components — 30 second check prevents mid-job surprises
- Site prep: level ground, 3-foot clearance, intake upwind, exhaust downwind
- Unfold by lifting and laying — never drag fabric on the ground
- Secure blower duct connections tightly; loose ducts lose 20–30% CFM
- Install pre-filter on intake, carbon filter on exhaust — check airflow direction
- Use soapy water spray on connections to detect air leaks instantly
- Dry the booth before folding and storing to prevent mildew
