Patio Concrete Coating in Lemont, IL

Epoxy flake coatings for Lemont patios, steps and the walks that run between them: one textured, waterproof, colored surface bonded onto every level of the concrete you already have, with grip where the ground drops and a UV-stable topcoat over all of it, installed by our own crew.

What is an outdoor flake coating?

An outdoor flake coating is an epoxy floor built in layers on top of an existing concrete slab. The concrete is ground, a primer is rolled in and fuses into it, a pigmented base coat goes over the primer, colored flakes are broadcast into the wet coat until the concrete is hidden, and a clear polyaspartic topcoat is applied over the flake to lock it in and stand up to the weather. The layers cure into one seamless, waterproof surface that follows the slab, including down a flight of steps.

We install it for Lemont homeowners whose outdoor concrete comes in levels: a patio at the back door, steps down, a walk running out to the yard or the garage below, sometimes a second pad at the bottom. It suits any sound slab that is gray, stained, worn or slick when wet, and it suits steps in particular, because the texture can be set heavier exactly where a foot lands.

The finished floor is colored, textured underfoot on every level and closed against water, so rain runs off it and down rather than into it, and it is rinsed clean with a hose. Outdoor floors we have coated, steps included, are on our gallery.

Why coat concrete on a slope rather than rebuild it

Rebuilding outdoor concrete on a sloping lot is a large job: the old slabs and steps have to be broken out and carried up or down the yard, forms built on the grade, and new concrete poured and finished in place. Pavers on a slope shift and settle unless the base is rebuilt. A coating keeps every level that is still sound and turns the whole run into one finished floor for a fraction of the cost and none of the disruption.

Nothing is broken out and nothing is hauled away. The coating adds only a fraction of an inch, so every step stays the same height, the nosing of each tread stays where a foot expects it, and the falls that carry water down and away from the house are kept as they are.

It is also a floor that is set for the way it is used. On a flat patio the flake's own texture is enough; on the steps and the slope down to the yard the grip is increased in the topcoat, and the blend is chosen so the edge of each tread reads clearly. Same system on every level, adjusted where it matters.

What a coated run of concrete gives you

Grip where the ground drops. The orange-peel texture of a flake floor holds a wet foot, and an anti-slip additive is broadcast into the topcoat on the treads, the landing and the sloping walk so the grip is heaviest where a slip would matter most. A bare or painted step is slick in rain and worse under wet leaves; a coated one is not.

Water kept out of the concrete. On a slope more water crosses the concrete to get in, and the steps take the worst of it. The coating closes the surface, so rain runs down and off instead of soaking into the slab and freezing inside it through the winter, which is what breaks the surface off bare treads. The topcoat is UV stable, so the color does not yellow or fade on a south-facing run.

Cleaned with a hose, and built to last. The surface is seamless and non-porous, so leaf stains, mud tracked up from the yard, grill grease and pollen rinse off rather than soaking in, and there is nowhere for mold to take hold. The finish is low odor, low VOC and pet friendly. A flake floor is built to last 15 to 20 years, and when a tread that takes the most traffic finally wears, it is refreshed with a new topcoat rather than replaced; a chipped area can be re-flaked to match.

Texture, blend and topcoat, set level by level

The texture comes first on concrete with steps in it. Every flake floor has the orange-peel finish that gives grip when wet, and on a flat patio that is usually enough. On the treads, the landing and any walk that runs downhill, the anti-slip additive is broadcast into the topcoat so the grip is heavier exactly there, and the flat areas are left with the standard finish.

The blend is chosen against the house and for the steps. Epoxy flake comes in a wide range of color blends and flake sizes, from quiet grays and tans to blends with a clear color in them. On a run with steps we lean toward a blend with enough contrast in it that the edge of each tread shows in evening light, and a fine flake where the surface has to hide mud from the yard.

The topcoat is the same clear polyaspartic on every level: UV stable so it resists yellowing and fading, abrasion resistant so grit carried up the steps does not wear through it, and glossy enough to bring the color of the flake up. It is the layer that meets the weather on every tread.

Preparing steps and slabs for a coating

Every level is mechanically ground, the treads and risers included. Diamond grinders take off the weathered surface, old paint, moss and algae staining, efflorescence and laitance, and open the pores of the concrete so the primer can bond into it. The treads and risers get the same grind as the patio, so the bond is the same on every level.

Cracks are opened out, cleaned and filled flush. Spalled and chipped step edges are repaired so each tread has a clean edge under the coating, and pitting on the walk is filled so it does not show through the flake. Control joints are treated so the coating runs across them cleanly.

Falls are checked on every level, because on a slope the water has to keep moving. A settled slab that holds a puddle at the foot of the steps is filled before the coating goes on so the water carries on down the yard. We look at all of this on the visit.

Installation, from the patio to the bottom step

The primer goes on first, rolled into every ground surface from the patio down to the last step. It fuses into the concrete and forms the bond that stops a coating from lifting, which is the failure a painted step has after one winter. Once it has cured, the pigmented base coat is applied across each level and down each riser.

The colored flakes are broadcast into the wet base coat until none of the concrete shows, treads and risers included. When that coat has cured, the loose flake is scraped and swept off, which leaves the even texture that gives the floor its grip.

The clear polyaspartic topcoat is applied last over the whole run, with the anti-slip additive broadcast into it on the steps and the slope. It locks the flake in, seals the surface against water and is the layer that takes the sun, the feet and the hose for the life of the floor.

Outdoor concrete around Lemont

Lemont sits on the side of the river valley, and a great deal of the housing sits on ground that moves with it, which is why so much of the outdoor concrete here comes in levels: a patio at the door, steps down, a path running out to the yard or to the garage below, and a pad at the bottom. That is exactly the concrete a flake coating is designed for, one textured surface across every level with the grip set where the ground drops, and we coat patios, steps, walks and pool decks across Lemont and the neighboring southwest suburbs.

We come out from our shop in Roselle with our own installers, not subcontracted labor. We are licensed and insured, we back the work with an extended warranty on our craftsmanship, and the person who walks the run of concrete with you is one of the people who will coat it.
