Basement Floor Coatings in Atlanta, GA

Basement floor coatings in Atlanta are a different job from garage floors, and the difference starts in the ground. The city sits in the Appalachian foothills, and the Piedmont region it belongs to has rolling hills and generally clay-like soils. Many homes are built into slopes with a daylight basement opening at the back, so part of the slab sits against the hill. Clay soil holds water and drains slowly. After a long rain, moisture can push up through a below-grade slab as vapor even if you never see a puddle. A basement floor coating laid without knowing that can bubble, lift or haze.

Moisture testing comes first

Every basement estimate we do includes a moisture test. We also look for white mineral crust on the slab or walls, dark spots, musty smells, rust at the bottom of posts, and peeling old paint, all signs that vapor or water is moving through. From the readings we choose a primer. A standard epoxy primer works on dry slabs. Slabs with higher vapor readings need a moisture-tolerant or vapor-mitigating primer underneath the finish. If water actually comes in during storms, a coating is not the fix. Drainage, grading or waterproofing has to come first, and we will be straight with you about it.

Remember September 2009

In September 2009, flooding across metro Atlanta caused major damage to some 20,000 homes, businesses and other buildings. Sweetwater Creek reached its highest level ever recorded, and creeks such as Peachtree Creek and Nancy Creek ran near or above record levels. Many basements took water, and some of those slabs have been wet since. If your lower level flooded then or after any big storm, mention it at the estimate. It changes how we test and what we put down.

Older basements and newer ones

Tucker and other inner suburbs have many 1970s and 1980s homes built over daylight basements, and intown houses from earlier eras may have partial basements with rough, patched floors. Newer homes in the northern suburbs often have large basements finished for media rooms, gyms or guest space. Old basement slabs usually need paint and adhesive removed, cracks filled, and low spots leveled. Newer ones may have sealers to grind off. Either way, the slab is diamond ground before coating so the primer bonds.

Finishes that suit a basement

For storage rooms, laundry rooms and utility areas, a solid-color epoxy or a chip system is tough and easy to clean. For a family room, gym or home bar, a chip floor adds texture and warmth, and metallic epoxy creates a showpiece. Basements rarely see direct sun, so standard epoxy topcoats work in many of them, though a polyaspartic topcoat adds scratch resistance where furniture moves a lot. We also think about grip near walkout doors and bathrooms.

Humidity in the house, too

Atlanta summers are muggy, and basements are the coolest part of the house. A cool slab in a humid basement can sit near the dew point, which is when condensation forms. Slab temperature and dew point get measured ahead of every coat, and we may run a dehumidifier during the job. A dehumidifier afterward also helps keep the room and the floor comfortable.

Getting the room ready

Basement jobs mean moving everything off the floor, and lower levels tend to collect a lot. We need the floor clear, access to outlets for equipment, and a way to bring in grinders and vacuums, usually through a walkout door or the garage. Finished walls and baseboards are taped and protected, and we can carry the coating a few inches up concrete stem walls for a clean edge. If you are planning a full basement finish, the easiest time to coat is before carpet, cabinets and trim go in, while the slab is open and easy to grind.

Pairing a coating with a dehumidifier

A coated slab stops dust and gives a clean, light-reflecting surface, but it does not change the humidity in the room. In a muggy Atlanta summer, a basement can stay damp enough to feel clammy and grow mildew on stored boxes. Running a dehumidifier helps the room and helps the floor by keeping the slab from sitting at the dew point. Pair that with gutters and grading that send roof water away from the house, and the floor will have a much easier life.

Sump pits, drains and transitions

Basements often have floor drains, sump pits, a water heater, a furnace on a pad, and steps or thresholds to other rooms. We coat around drains so water still flows to them, leave sump covers removable, and finish neatly at doorways and stair landings. If you plan to change flooring in the next room, tell us so the transitions line up.
