Containment & HEPA Setup for Cabinet Refinishing
Full containment walls, HEPA-rated air extraction, and sealed negative-pressure containment during the sanding and finishing stages.
What mess does cabinet refinishing usually create?
Done without containment, cabinet refinishing generates fine wood dust from sanding and overspray from spraying. HEPA filters are rated to capture 99.97% of airborne particles at 0.3 microns. Parallel Painting uses HEPA-rated extraction and sealed negative-pressure containment during the sanding and finishing stages.
When you compare bids, ask each contractor exactly how they contain dust and overspray, what they mask and protect, and what equipment they use.
Dust control is also part of the finishing process: particles that land in wet finish can create texture in the surface. Parallel Painting uses HEPA-rated extraction and sealed negative-pressure containment during the sanding and finishing stages.
How does our containment system work?
At Parallel Painting, containment is not an afterthought — it is engineered into every project from day one. Here is exactly what we do:
Floor-to-Ceiling Containment Walls
Before any sanding or spraying begins, we build floor-to-ceiling plastic barrier walls around the entire work area. These are not loose sheets of plastic taped to the ceiling — they are tensioned barriers with sealed edges along the floor, ceiling, and adjacent walls. Every seam is taped. Every gap is sealed. The work area becomes a fully enclosed room within your kitchen.
Negative-Pressure Containment
We run HEPA-rated extraction fans that pull air out of the containment zone and exhaust it outside. This creates negative pressure inside the work area. Parallel Painting uses HEPA-rated extraction and sealed negative-pressure containment during the sanding and finishing stages.
HEPA Extraction Equipment
HEPA filters are rated to capture 99.97% of airborne particles at 0.3 microns. Our extraction system uses HEPA-rated filters. This is not a shop vacuum with a filter bag — it is industrial air purification equipment.
Controlled Spray Environment
Once containment is established, we spray cabinet frames on-site using professional HVLP equipment within the sealed environment. Doors and drawers are removed and finished off-site in our controlled spray setup. Cabinet frames are finished on-site within the sealed work area; doors and drawers are finished off-site.

What does the process look like in action?
Full containment in a residential kitchen — plastic walls, sealed edges, HEPA extraction running.
How do we spray inside your home without overspray?
Beyond dust control, spray application is central to how Parallel Painting finishes cabinets. Parallel Painting uses spray application for its cabinet-finishing process; other manufacturer-approved cabinet coatings may permit brush, roller, or spray application. On large flat cabinet doors, the finishing method affects how the surface reads under kitchen lighting.
Professional HVLP spray application atomizes the coating into a fine mist that lays down in even, thin coats, producing a smooth sprayed finish. Parallel Painting uses spray application for its cabinet-finishing process; other manufacturer-approved cabinet coatings may permit brush, roller, or spray application.
Our HVLP setup is run inside the sealed plastic enclosure. Parallel Painting uses HEPA-rated extraction and sealed negative-pressure containment during the sanding and finishing stages.
Why surface preparation matters for adhesion
When you compare refinishing options, ask each contractor exactly what surface preparation they do — how they clean, sand, and prepare the existing finish before a new coating goes on. Surface preparation is one of the factors that affects how well a finish adheres.
Parallel Painting's process uses mechanical sanding to create a clean, profiled surface for the new coating to bond to. Spray application generates overspray regardless of the preparation method, which is why we pair sanding with HEPA-rated dust extraction and sealed negative-pressure containment.
Properly sanded surfaces give the new coating a clean, profiled surface to bond to. Parallel Painting uses HEPA-rated extraction and sealed negative-pressure containment during the sanding and finishing stages.
