Concrete sealing and grind and seal
Sealing concrete against water and stains, and the honest grind-and-seal finish for slabs with good character.
The build-up, step by step
Every concrete sealing job Shanks installs follows the same order, because skipping a stage is how floors fail. Taylor is on site for all of it.
Clean and open
Grinding takes off the sealed skin so the sealer can penetrate rather than sit on top.
Optional stain
Acid or water-based stain where you want color that comes from within the concrete rather than a film on top.
Seal
Penetrating sealers for a natural matte look; film-forming for gloss and stronger stain resistance.
Burnish
Buffed to an even sheen.
Right room, right system
Shop floors, basements, stamped patios, driveways and any slab whose character is worth keeping.
Where it is the wrong call
Slabs that need to look uniform. Sealing amplifies what is already there, including old repairs.
Back in service: Foot traffic in a day, vehicles in two to three.

Why this floor costs what it costs
A quote on this work is really a quote on preparation. Here is what Taylor is looking at when he walks a floor:
Condition of the slab
A clean, sound slab grinds in a morning. One carrying old paint, carpet glue, or a failed coating can take a full day longer before anything can be applied.
Size and shape
Bigger floors cost less per square foot, because the setup, the mixing and the cleanup are much the same whether the room is 400 or 1,400 square feet. Cut-up rooms with lots of edges take longer than open ones.
Access
A walk-out basement with a door at grade is straightforward. Carrying equipment down a flight of stairs, or working around a building that has to stay open, adds time.
Moisture in the slab
If testing shows vapor moving up through the concrete, a mitigating primer goes down first. It is an extra step, and skipping it is how coatings fail.
What Alabama slabs do
Out toward Gadsden, Southside and Pell City there are a lot of walk-out basements cut into a hillside. Those slabs sit against earth on three sides, so they get moisture-tested before a quote rather than after a failure.
Alabama humidity is the quiet variable in this work. Resin cures on a temperature and dew-point window, so a floor is scheduled around the weather rather than squeezed in before a storm rolls over Talladega.
Where the trailer goesWhat the days actually look like
People are usually more anxious about the disruption than the floor. Here is what the days actually look like:
Agreeing the spec
Profile, moisture limit and flatness get agreed in writing before anything starts, so there is no argument later about whether the slab was ready.
Containment
HEPA extraction on every machine, and sheeting where the work sits next to an occupied area.
Grinding to the profile
Grinding or blasting to the agreed profile, with joints and cracks handled to your detail.
Handover
Vacuumed, documented and ready to coat, with the moisture numbers written down for your manufacturer warranty.
Keeping it looking new
A sealed floor is the one system here that is meant to be renewed. Sweep it and mop it with a neutral cleaner, keep de-icing salt off it in winter, and watch for the sheen going patchy in the traffic path: that is the sealer wearing, not the concrete, and a fresh coat over a clean surface brings it back without grinding. Outdoors that is every few years; indoors considerably longer.
Anything Taylor installs comes with a walk-through at handover covering exactly this, plus what to avoid in the first two weeks while the coating reaches full hardness. If something does go wrong later, tell him about it rather than living with it.
The owner is the installer
Shanks Concrete Coatings is Taylor and Heather Shanks, working out of Anniston. Taylor trained directly with Brian Phillips, The Epoxy Dude, in southern Indiana, and he runs the grinder and pulls the squeegee on every job himself. Licensed and insured, Alabama #2602341.
If a concrete sealing floor is not the right answer for your room, he will tell you that on the first visit rather than sell it to you. More about how Shanks works, or send over the details of your floor.
Concrete Sealing questions
What is grind and seal exactly?
The slab is ground to open it and even out the surface, then sealed. It costs less than a full polish and keeps the concrete’s own look, which is why it suits shops and stamped patios.
Will sealing darken my concrete?
A film-forming sealer wets the color and deepens it, like concrete looks when it rains. A penetrating sealer barely changes it. Both get sampled on your slab first.
How often does it need redoing?
Outdoors, several years depending on sun and traffic. Indoors, considerably longer.
Can a stamped patio be resealed?
Yes, and it is one of the most common outdoor jobs. The old sealer comes off first, otherwise the new coat locks in the cloudiness.
Will sealing stop my garage floor dusting?
Largely, yes. Raw concrete sheds fine dust under traffic as the surface breaks down. A penetrating sealer or a densifier hardens that surface so it stops shedding, which is often the real reason people call about a shop floor.
Four questions worth asking any installer
Ask these of Shanks and of whoever else you are talking to. The answers separate a floor that lasts from one that looks good for a season, and a straight installer will not mind being asked.
How are you preparing the slab?
The only acceptable answers involve a diamond grinder or a shot blaster. Acid etching and a scrub with degreaser is not preparation, and it is the single most common reason a coating lets go.
Are you testing for moisture?
On any basement or ground-level slab this should be a yes with a number attached. Vapor pressure will push a coating off no matter how good the product is.
Who is actually on my floor?
Worth asking whoever quotes you. With Shanks the person who quotes it is the person who grinds it and coats it, and that is not true everywhere.
What is the topcoat?
A UV-stable polyaspartic or aliphatic urethane holds its color. A cheap job leaves a standard epoxy as the top layer, and it will amber in daylight within a year or two.
Other systems for the same room
Concrete Sealing is one of twenty-two systems Shanks installs. If the room is telling you something different, these are the closest alternatives, and Taylor will happily point you at the cheaper one if it is the right answer.
