Worn multifamily common floors are a CapEx and tenant-experience problem—not just cosmetics. This is an honest multifamily concrete floor resurfacing Seattle guide for property managers, ownership groups, and on-site maintenance leads: when patch, cementitious overlay, or densify-polish may still fit; when a coating goal is honest on a sound, dry slab; when section replace is the durable call; why unit interiors, parking-deck membranes, warehouse polish, residential garage epoxy, and public ROW sidewalks are different conversations; why Olsen will not publish a rate card online; and how photos plus a credited on-site assessment get you a real plan. Call (425) 215-2560.
Common-area concrete on apartments and condos usually means lobbies, laundry rooms, corridors, breezeways, mail/kiosk pads, and entry vestibules. A sound slab with surface wear is often a patch + cementitious overlay candidate, and sometimes a densify-polish candidate after screening. A sound, dry slab with chemical resistance, seamless wipe-down, or decorative film goals opens a coating conversation—see polished concrete vs epoxy; Olsen confirms what finishes fit on assessment and does not claim to install every epoxy brand. Delaminated coating, chronic moisture, heaved or failed panels, or structural cracks usually need strip + repair or section / full replace—do not coat over failure. Start with a complimentary phone/photo review; the on-site assessment is credited if you proceed. Call (425) 215-2560.
In scope: interior and covered multifamily / condo common-area concrete floors across King, Snohomish & Skagit—restore vs coat vs polish vs section replace, plus honest PM phasing notes.

Interior lobby, corridor, and laundry floors are this page’s primary. Open breezeways still sit on the common-area restore ladder, with weather and slip honesty on assessment. Guest-facing outdoor dining or commercial plaza flatwork: see restaurant plaza concrete repair. ROW sidewalk trip lips belong on the sidewalk page.
Western Washington common floors wear from tracked rain soil at entries, laundry detergent and moisture load, coatings applied over damp slabs, deferred CapEx, and heavy rolling carts. Indoor overlays and coatings commonly need moisture awareness before install—especially laundry and below-grade spaces. See moisture vapor test before overlay. Olsen confirms testing needs on assessment and does not publish RH%/MVER pass/fail numbers as company specs. When flatness is the prep question, see self-leveling vs grinding concrete.
Sound, stable slab; surface spall, stain, or wear; overlay can bond after mechanical prep. Many apartment lobby and corridor floors fit this path when sounding and moisture screening pass. See concrete overlays and commercial overlay vs replace.
Sound slab that can take grind–densify–polish; dusting or tired cream; FM wants a slab finish, not a film. For warehouse / retail / showroom polish details, see commercial concrete polishing Seattle. Multifamily lobbies are a different traffic and access conversation.
Film, chemical, or decorative goals on a sound, dry slab open a coating conversation—see polished concrete vs epoxy. Peeling existing coating, active moisture, or soft / delaminating substrate means fix the substrate first. Do not recoat failure. Coating ads and per-square-foot price ranges from outside sources appear online—treat them as general planning guidance only; Olsen confirms scope on assessment and does not republish those numbers as company rates.
Structural cracks, heaved panels, failed base, or repeated coating failure from moisture usually need section or full replace. Phased panel replace vs whole-corridor tear-out is confirmed on assessment—not made-up from photos alone.
Occupied buildings need phased zones, after-hours or weekend windows, elevator and loading notes, and a clear building contact. Olsen plans access with the PM—and does not publish “always back in 24 hours” downtime SLAs. Send access constraints with your photos so the complimentary phone/photo review can screen candidacy honestly. Portfolio sidewalks and exterior entries still start on the property managers hub; facility teams can start with facility managers.

Drivers: area size, prep depth, overlay vs polish vs coating path, moisture mitigation, phasing / after-hours access, and section-replace volume. Local and national pages sometimes publish resurfacing $/sq ft bands, grit tiers, or “epoxy lasts X years” claims—treat those as general planning guidance, not Olsen’s price list. Olsen does not publish one-size $/sq ft, grit tables, COF ratings, cure-day guarantees, or coating lifespan warranties.
