What is concrete sealing?

Concrete sealing is the simplest floor treatment we install. The slab is mechanically ground to take off dirt, stains and whatever was put on it before, and a clear sealer is applied to the clean concrete. Nothing is laid over the floor: the sealer bonds to the concrete and closes the surface, so the slab itself becomes the finished floor.

We install it for the Franklin Park businesses with a lot of floor and no case for coating all of it: warehouses, freight and distribution buildings, production floors, stores and the working half of a commercial unit. It suits any sound slab that is dusty, stained and hard to keep clean, and it suits the big ones best, because the cost per square foot stays low across a large footprint.

The finished floor is the concrete you already own with its natural color kept, no dust coming off it, and a surface that is non-porous, so a spill sits on top and mops away. Ground and sealed floors we have installed are on our gallery.

Why seal a warehouse floor instead of coating it

A bare slab is porous. It sheds dust into everything stored on it, it soaks up oil and forklift marks, and every spill becomes a stain. A full coating fixes all of that, but on a large warehouse floor the cost of a coating build over the whole area is hard to justify when most of it only needs to stop dusting and clean properly. Sealing is the treatment for that floor.

It is also the treatment that adds nothing to the building. There is no demolition and no new floor laid, and a sealer is a thin clear layer rather than a build-up, so the level at a dock leveler, a roller door or a threshold stays where it is. For a building that runs pallet trucks and forklifts through doorways all day, that matters.

Sealing is fast to install and the disruption is small, so it fits a working building with minimal downtime. Where a small part of the floor genuinely takes a beating, a coating can go there and the sealed concrete runs up to it, one crew, one visit, and the budget spent where the wear is.

What a sealed floor does for the building day to day

No more dust. A ground and sealed slab stops shedding the fine cement dust that a bare warehouse floor produces under traffic, so it stops settling on racking, stock and machinery, and the sweeping that never quite worked becomes a sweep that does.

Easy to clean and hygienic. Once sealed, the concrete is non-porous. Liquids, oil, mold, bacteria and dirt cannot get trapped in it, so a spill is wiped or mopped rather than absorbed, and the floor is cleaned with a mop and plain soap and water. Nothing to strip and nothing to wax.

Protected from what a working floor sees. The sealer protects the concrete from oil, grease, chemicals, road salt tracked in on tires and moisture, and it is UV stable, so it does not yellow in the daylight from a dock door. The slab underneath is preserved instead of slowly stained and worn, which is why sealing is the cost-effective alternative to replacing a floor that is fundamentally sound.

Three ways to seal a Franklin Park floor

A clean-up grind and seal. The floor is ground enough to strip the dirt, the stains and any old sealer or paint, and the sealer goes onto the cleaned concrete. The floor keeps its own color and texture, it just stops dusting and starts cleaning. This is the usual choice for a warehouse or production slab where the look of the floor matters far less than what it does.

Grind and seal for a polished look. The grind goes further and takes the surface back to clean, even concrete before the sealer is applied. The result has the look of polished concrete at a lower price: a smooth, light floor that reflects the lighting and brings up the color in the slab. It suits a store, a showroom or the customer-facing part of a building, and it comes from the same slab as the plain version.

Concrete sealing outdoors. The same grind and seal protects exterior concrete: patios, walkways and driveways at a business or a home. Outside, the sealer stops water and salt soaking in and stops the surface staining and weathering, and it keeps the concrete looking new for far longer than it would bare.

Preparing a large slab for the sealer

Every job starts with mechanical grinding, whatever the size of the floor. The grinders take off the dirt, the tire marks, old paint, previous sealers and the laitance on the surface, and they open the pores of the concrete so the sealer can bond to it. How far the grind goes sets the look; that it happens at all is what decides whether the sealer holds.

Cracks, holes, spalls and the damage around racking feet and dock edges are opened out, cleaned and filled flush before the sealer goes on, so they stop growing and stop collecting dirt. Control joints are cleaned out so the sealed floor runs clean across them.

The edges of the floor are ground right up to walls, columns, dock levelers and door tracks, so the sealed surface is continuous. Where two areas of slab meet at different levels the transition is ground and filled to one plane, and a cove at the wall is an option we talk through for areas that are washed down.

How the sealer goes on

A sealed floor has fewer layers than a coated one. There is no primer and no pigmented base coat to build up: once the concrete is ground, repaired and vacuumed clean, the clear sealer is applied directly to the slab. It bonds to the ground concrete and closes the surface, which is what makes the floor non-porous.

The sealer is applied in coats, each worked evenly across the floor so the finish is consistent from the dock to the back wall. On a floor ground for the polished look the coats are what bring up the depth of color and the light reflection.

Where a small area is being coated instead, that part gets its own primer, base coat and topcoat, and the sealed concrete is finished up to its edge. On a plain sealed floor the sealer is the wear layer: the surface that takes the traffic, the spills and the cleaning for the life of the floor.

Where sealed floors go in Franklin Park

Much of the building stock in Franklin Park is warehousing and freight space near O'Hare and the rail corridor, and a lot of it has floor area far beyond what a full coating would ever be justified on. That is exactly the floor sealing is for: a large older slab that is sound but open, dusty and impossible to keep clean. We seal warehouse, distribution, production and commercial floors across Franklin Park and the neighboring suburbs.

We work out of our shop in Roselle with our own installers, not subcontracted labor. The company is owned and operated by a Marine Corps veteran, we are licensed and insured, and the people who come out to look at your floor are the people who will seal it.
