Epoxy Flooring in Boulder, CO

Epoxy flooring in Boulder covers a wide range of floors, because Boulder's housing does. The city was founded in 1859 and incorporated in 1871, and parts of it, like Mapleton Hill, are still lined with homes more than a century old. Other neighborhoods are mid-century ranches with basements, and some are newer builds with oversized garages. Each of those slabs needs a different kind of prep before it is coated.

Historic districts and detached garages

Mapleton Hill was developed starting in the 1880s, and nearly 57% of its roughly 500 homes predate 1910, according to the City of Boulder. Garages behind homes like these were often added later, poured thin, patched over the years and painted more than once. Those floors usually need old paint ground off, uneven patches leveled and cracks chased before a coating will bond. Garage interiors are not usually what a historic review focuses on, but if your property is in a historic district and the work touches anything visible from the street, it is worth checking with the city first.

Gear first, cars second

Plenty of Boulder garages are really storage for bikes, skis, climbing gear and camping equipment. A coated floor suits that: wet boots and muddy tires drip onto a sealed surface instead of soaking into bare concrete, and grit sweeps right off. A light flake blend makes small parts easy to find at a tuning bench.

Weather that tests a coating

Boulder averages close to 90 inches of snow a season, by NOAA's 1991 to 2020 records, and chinook winds have gusted past 100 mph. Strong winter sun and sudden warm-ups mean an unheated garage can freeze and thaw repeatedly through the season, with de-icer brine tracked in each time. A flexible, UV-stable polyaspartic topcoat over a properly ground slab is well suited to that pattern.

Basements and the 2013 flood

During the September 2013 flood, Boulder took about 17 inches of rain in a week, including a record 9.08 inches in a single day. Before coating any basement here, we test the slab for moisture and look for signs of past water, such as efflorescence or stained edges, so the coating is matched to what the slab is actually doing.

Renters, owners and resale

Just under half of Boulder homes are owner-occupied, and the median value of an owner-occupied home is above $1 million (Census, 2020 to 2024). For owners, a coated garage or basement is a durable upgrade that shows well at sale time. For landlords, a sealed floor is easier to clean between tenants than bare concrete or carpet.
