What is polished concrete?

It is your existing slab turned into the finished floor. We grind the surface with a run of progressively finer abrasives, harden it so the pores close, and polish what that leaves. Nothing is laid over the top, so there is no coating to chip or peel away.

Can any concrete floor be polished?

Most sound slabs can. What rules a floor out is damage rather than age: heavy patching, deep flaking, or a surface that has already been ground badly once. We can usually tell from a short look whether the concrete under your feet is worth polishing. We come out and read floors right across Los Angeles County, and the cities we cover are listed in full.

Is polished concrete suitable for outdoor use?

Indoors is where it belongs. A high polish gets slippery once it is wet, and weather works on an open concrete surface far harder than a living room ever will. Outside, on a driveway or a porch, restoring the concrete itself is the work that suits those surfaces.

How do you maintain polished concrete floors?

Sweep it, and damp mop it when it needs it. There is no wax to strip and no resealing cycle to keep up with, because the hardness sits in the concrete itself rather than in a layer resting on top of it. A polished floor that has taken years of traffic can be brought back at the top level without disturbing the cut underneath.

When should polished concrete be installed?

On a new pour, after the slab has fully cured, which is usually about 28 days. On a floor that has been down for years the timing is easier, because the concrete finished curing long ago and the only real question is when the room can be emptied for us.

Polishing Cuts Into the Floor You Already Have

Most flooring work is additive. A coating is mixed, spread and left to cure, and when it is done there is a new layer sitting on your concrete. Polishing works the other way round. Nothing is added at all. We run a sequence of increasingly fine abrasives across the slab, and each pass cuts a little further into the surface than the one before it.

That one difference decides everything else about a polishing job. There is no product to choose, no color to pick off a chart, and no film that can lift or peel later, because there is no film. What you end up with is the concrete that was poured into the building years ago, closed up and taken to a sheen.

It also means the floor cannot be taken back. A coating that disappoints can be ground off and a different one put down in its place. A cut cannot be undone. Once we have opened the surface and brought up what is inside it, that is your polished floor, and the only direction left is deeper.

How Deep We Cut Decides What You See

Concrete is not one solid color the whole way through. It is stone and sand held together by cement, and the cement rises as the slab is poured, so the top fraction of an inch is nearly all paste with the stone sitting under it. How far we cut through that paste is the single decision that changes what the polished floor looks like.

A Light Cut Leaves the Paste in Place

The shallowest option barely goes below the surface. We open the paste, close it again with a hardener that soaks in and sets inside the pores, and polish what that leaves. The floor stays close to the color the slab already is, with none of the stone showing, and it is the least costly way to polish concrete that is in sound order. Garage slabs are the ones we are asked about most, and a garage floor coated in epoxy is usually the alternative being weighed against this one.

A Deeper Cut Brings the Stone Up

Cut further and the paste is gone. First comes a fine, even speckle where the tips of the sand and the smallest stones break through, and then, further down again, the full face of the aggregate: the actual gravel that went into the mix, cut open and polished. Neither look can be ordered in. Whatever the batch plant put into that slab is what comes up. We see the deeper cuts most often in commercial rooms, where a warehouse floor has to carry traffic and nobody wants a coating lifting under it.

When the Slab Is Not a Candidate

Some floors are ruled out before we start. Polishing shows everything the concrete has been through, so old repairs, saw cuts, pipe trenches and the outline of a wall that once stood there all stay in view once the surface is open. Polishing is the one option here that adds nothing on top: the floor you end up with is the slab itself. Where the concrete is too damaged or too patched for that, a coating that covers the damage is the better route. A slab that has moved or settled needs leveling work in its own right before any finish goes anywhere near it.

The Sheen, and What It Will Not Give You

Once the depth of the cut is settled, the last choice is how much light the floor gives back. We can stop at a matte surface that reads almost dry, take it on to a satin that lifts a little under a lamp, or keep going to a high gloss that mirrors the room above it. The stone underneath does not change with any of them. All that changes is how finely the surface is closed. If you want color or a decorative flake rather than exposed aggregate, that is an epoxy floor or a polyaspartic finish instead.

Polishing usually costs less than coating the same room, for the plain reason that there is no material going down. You are paying for machine time and for abrasives rather than for resin. What a polishing job comes to on your floor depends on how hard the slab is, how deep we have to cut and what the machine finds when it opens the surface, so we read the concrete first and quote from that rather than from a rate. Call us and we will come and look at it.
