Is polished concrete cheaper than epoxy?

The ranges overlap. Basic polishing runs about $3 to $12 a square foot and installed epoxy about $4 to $10, so the slab decides it. A sound slab that only needs a cream polish can come in under a coating. A pitted or patched slab that needs deep grinding and filling can cost more than an epoxy that would simply cover it.

Can an old garage floor be polished?

Sometimes. Polishing grinds into the concrete you already have, so old stains, patches, cracks and oil soak-in stay visible, and deep pits show up as the grind goes down. Paint and sealer have to come off first. If the slab is badly damaged, a coating usually looks better; garage floor resurfacing covers that route.

Is polished concrete slippery?

Dry, it grips well enough for most rooms. Wet, a high-gloss polish can get slick, and cost guides note that polished floors that don't meet slip-resistance standards are slippery when wet. Kitchens, entries and wash areas should have a lower sheen or a slip-resistant treatment.

Polished Concrete Finishes by Grind Depth

Polishing grinds the slab itself with diamond tooling, hardens it with a densifier and brings it to a sheen. No coating goes on top. The deeper the grind, the more aggregate shows, and the more the floor costs.

Cream Polish

A cream finish takes off only the top skin. The Concrete Polishing Council's Class A surface is 85 to 95% cement fines with a little fine sand showing. It is the least grinding and the lowest price, at about $3 to $8 a square foot. The catch: with so little cut depth, a cream polish won't remove blemishes. It suits a newer slab with few patches, cracks or stains.

Salt-and-Pepper Finish

Grinding a little deeper brings up the fine aggregate. In Class B, 85 to 95% of the surface is fine aggregate, which gives the speckled look. Expect about $4 to $10 a square foot. Color can shift as the paste comes off, from gray toward brown depending on the sand. Ask for a mock-up on your own slab before the whole floor is ground.

Exposed Aggregate

The deepest grind cuts through to the coarse stone. Class C is 80 to 90% full aggregate, and the look is close to terrazzo. It runs about $6 to $12 a square foot. Deeper grinding also opens pits and voids in the slab that have to be filled, which the polishing council calls grouting. What you'll see depends on the stone in the original mix, so two slabs ground the same way can look very different.

Dyed Polished Concrete

Dye adds color without a coating, at roughly $1 to $3 a square foot on top of the polish. It colors the concrete itself instead of sitting on top as a film. Because the exposed sand and stone still set the base tone, the same dye looks different over a cream finish than over salt-and-pepper. Ask to see the dye on a test patch of your slab.

Grind-and-Seal

Grind-and-seal skips the finer polishing steps: the slab is ground, cleaned and coated with a clear sealer. Sealing alone costs about $1 to $3 a square foot. A true polished floor doesn't need a sealer because the densifier hardens the surface, though a stain guard helps in kitchens, garages and high-traffic areas. Grind-and-seal suits basements, garages and shops where a satin look is enough. A topical sealer wears with traffic, so ask how often yours will need a fresh coat.

Choosing a Sheen Level

Gloss is set by how far up the grit sequence the crew goes. The polishing industry describes four levels:

Level 1, flat
stopped below 100-grit resin bond; hazy, little reflection
Level 2, satin
stopped at 400 grit; low sheen, a slight reflection from about 100 feet away
Level 3, semi-polished
800 grit or higher; clearly reflects lights at 30 to 50 feet
Level 4, highly polished
up to 3,000 grit or burnished; a mirror-like look

A high gloss suits a showroom, but cost guides warn that a polish that doesn't meet slip-resistance standards is slippery when wet. For kitchens, entries and anywhere water lands, ask about a lower level or a slip-resistant treatment; anti-slip floor coating explains how slip resistance is rated.

When a Coating Is the Better Call

Polished concrete is not stain-proof, and chemicals can damage it. Shops where oil, brake fluid or solvents spill are better served by a coating; see industrial epoxy flooring for chemical-rated systems. Slabs with many cracks and patches are a poor fit too, since a polish shows every repair. For those, concrete crack repair followed by a coating covers what polishing would leave in view.
