Elmhurst Epoxy Flooring brings more than 20 years of experience to epoxy flooring in Warrenville, and a growing share of that work sits inside buildings that never fully close. A break room, a fitness room or a copy room in an office suite can take a resin floor while the rest of the floor plate stays busy. That changes how the job is planned far more than it changes the coating itself.
Our approach starts the same way on every slab. We open the concrete with a diamond grinder or a shot blaster rather than an acid etch, we run a moisture test before the price is final, and the written proposal names the product line, the number of coats and the finished thickness. What follows on an occupied job is the air plan: where vapor goes, which returns get sealed, and when the coat actually goes down.
This page walks through that air plan for suite work in an office tower, which is how a commercial floor can be redone without emptying a building. Homeowners with garage questions will find the same grinding, testing and written scope behind every quote we write.
An Eight-Story Tower, One Shared Air System
What stands at 28100 Torch Parkway
The Cantera Meadows office tower at 28100 Torch Parkway sits inside the City of Warrenville, in Naperville Township of DuPage County. Published leasing coverage describes it as an eight-story Class A building built in 1997, with a two-story granite and wood lobby. A renovation covered the lobby, elevator cab interiors, exterior and entryways, and tenants were offered an expansive cafeteria, conferencing and a new fitness center.
Its tenancy shows how the building is used. EN Engineering, the city’s largest employer at 1,000 people, leased 84,399 rentable square feet in the lower portion of the 203,842-square-foot tower, and a 26,610-square-foot sixth-floor build-out for another tenant was reported in 2014. We have no relationship with the owner or any tenant there, and we have not seen its suites or its mechanical drawings.
Why one suite is never alone
A multi-tenant tower is the clearest case of a floor that has to be coated while other people work around it. Whichever room in a building like this gets resin, whether a break room, a fitness space or a server or copy room, the tenants around it are still at their desks on the same air system. The coating is local, but the air it releases into is not.
Return air is the pathway that matters. Air drawn out of the suite travels back to the air handler, mixes, and is delivered to other rooms, so solvent vapor and odor from a fresh coat can show up several suites away. How any particular building’s HVAC is zoned is something we confirm with its engineer rather than assume.
What absorbs the odor
Carpet, ceiling tile, fabric panels and wall coverings are porous, and porous finishes take up odor and release it later. A suite can smell clean the morning after a coat while the carpet next door is still giving back what it absorbed overnight. That delayed release is why the controls below aim to keep vapor out of the return in the first place, rather than flushing it out of neighboring suites afterward.

How Occupied-Building Air Rules Treat a Resin Floor
Owners who manage work in an occupied building often write their requirements around the SMACNA guideline for indoor air quality during construction, ANSI/SMACNA 008-2008. One published example is the University of Alabama at Birmingham’s construction standard, which requires that guideline on all its projects and spells out what it means in practice. It does not single out floor coatings; it treats any finish that emits volatile organic compounds the same way.
HVAC protection
The standard calls for return air openings to be sealed completely during high-dust work, with MERV 8 filtration at each return grille if the air handlers must keep running. For a floor job that applies twice: once during grinding, when dust is the concern, and again during the coat, when vapor is. We vacuum grinding dust at the machine as it is cut, so the return seal is a second line of defense rather than the only one.
Source control
The same standard asks for low-VOC products and for containers of wet-applied products to stay closed as much as possible. On a coating job that means mixing only what the crew can place, keeping lids on between batches and taking empty pails out of the building promptly. It is a small habit, and it removes a source of vapor that has no reason to be in the room.
Pathway interruption and material protection
For the installation of VOC-emitting materials, the standard directs ventilation with 100 percent outside air, exhausting contaminated air directly outdoors, with supply and exhaust shut down or isolated where needed. It also names carpet, ceiling tiles, fabrics and wall coverings as porous finishes that tend to absorb contaminants and release them later into the finished building. That is one owner’s implementation of the guideline rather than its own text, and a given building may write its rules differently, so we ask for the owner’s requirements before quoting.
Low-Odor Systems, Sealed Returns and Off-Hours Work
Choosing the system for the room
Product choice is the first control, and we make it room by room. A low-odor system will do in many office spaces, where the floor sees foot traffic, chairs and the occasional spill, and a solvent-heavy product is hard to justify next to working tenants. Where a room needs more, such as a fitness space with heavier loads or a copy room with rolling equipment, we explain the tradeoff and name the product line, coats and thickness in writing.
Low-odor does not mean no odor. Any resin floor releases some vapor while it cures, and we say so plainly so a property manager can warn neighboring tenants honestly. Products are also picked inside the Illinois VOC limits for floor coatings, which bind whoever applies them.
Setting up the suite
Before any coating is opened, the returns serving the work area are sealed or, if the air handler has to run, filtered. The room is held under negative pressure with exhaust ducted straight outside, so air leaks into the suite rather than out of it. Doors to the corridor are closed off, and the setup stays in place until the coat has stopped giving off strong vapor, not just until it is dry to the touch.
Preparation follows the same scope as any slab. We grind or shot blast to open the surface, map cracks, spalls and old coatings, and test for moisture before the price is final, because an office slab can carry moisture just as a basement can. If a slab needs repair before it should be coated, the proposal says so.
Working with the building engineer
The schedule is built with the building engineer, because the engineer controls the air handlers, knows the zoning and decides when systems can be isolated. We plan the coat for after hours or over a weekend, when the fewest people share the air, and phase larger suites so one section closes while the rest stays open. Overnight and weekend windows are routine for offices, schools and hospitals that cannot simply close.
Building access is part of that conversation too. Freight elevator time, loading dock hours, where the crew stages material and how waste leaves the building all get settled before the job is booked. Those details decide whether a coat goes down on a Friday evening or slides to the next weekend.
Airing Out Before a Tenant Moves Back In
Ventilating through the cure
Exhaust keeps running after the last coat, because cure continues well after the surface feels dry. We leave the negative-pressure setup and the return seals in place through the early cure, then hand the room back to the engineer to restore normal air. Cure timing follows slab temperature rather than the calendar, so a building that turns its heat down on weekends can slow the schedule.
The walkthrough before move-in
Before the tenant comes back, we walk the suite with the property manager or engineer. Odor in the suite itself, odor in the corridor and any complaint from the neighboring space are all part of that check. If neighboring carpet or ceiling tile picked up odor despite the controls, that is reported rather than hidden, so the building can decide how to air that space.
What the paperwork should say
The handover lists what was installed, the number of coats and the thickness, matched against the proposal. We also explain what the coating warranty excludes, with moisture named first, before the job is sold rather than after. A tenant moving back into a coated break room or fitness room should know what the floor is, how long until full service and what voids its coverage.
Permits and approvals in Warrenville
The City of Warrenville’s permit page lists flooring among the work that does not need a building permit, but commercial work is handled differently on the fire side. The Warrenville Fire Protection District reviews and approves all non-single-family building and occupancy permits, so we confirm with the owner whether any part of a suite project passes through it. Inside a managed tower, the owner’s own construction rules often govern the work as much as either authority does.
If a suite in a Warrenville office building needs a new floor while the rest of the building keeps working, we start with a site walk, a moisture test and a conversation with the engineer. The quote that follows spells out the system, the air plan and the window, so everyone sharing the air knows what to expect.
