Polished Concrete 

Polished concrete is becoming very popular not just for its sleek modern appearance but for it's long term durability, ease of maintenance, environmental friendliness, sustainability and low life cycle cost to name a few. 

There are many different design options to choose from.  Let's look at some of the basics.

Aggregate Exposure

Class A

Cement fines.  The very top layer of the concrete.  This finish requires near perfect concrete finished with a power trowel.  

Classs B aggregate exposure

Class B

Fine Aggregate.  Just below the cream layer of concrete small aggregate becomes visible.  

Class C Aggregate exposure

Class C

Coarse aggregate.  Grinding further into the concrete exposes larger aggregates.  

While most concrete can be polished the condition of the slab can impact which aggregate exposures are possible.  A slab must be finished a certain way, be in relatively good shape and be very flat for a Class A exposure to be an option.


Floor Flatness measured with the F number system also known as FF, F numbers and F value is usually only specified and measured on commercial concrete pours greater than 10,000 SF.  The higher the FF number the flatter floor.  When polishing concrete flat floors are very important for uniform aggregate exposure.  A very bumpy floor with highs and lows will end up with a random combination of all 3 aggregate exposures.  The high spots are cut down exposing coarse aggregate while the low spots are still in the cream layer of the concrete.  


Gloss Level

Level 1 Flat

Level 1 Flat

Reflected images have flat appearance.

Level 2 Satin

Level 2 Satin

Reflected images have matte appearance.

Level 3 Polished Concrete

Level 3 Polished

Reflected images are not sharp and clear but can be easily identified.

Level 4 Highly Polished

Level 4 Highly Polished

Reflected images have sharp, crisp, mirror like appearance.

Control Joints

Saw cuts in concrete are called control joints.  They play an important role in preventing cracks from forming while concrete is shrinking as it dries.  They "control" cracking.  It's important to fill those joints not just for aesthetics and hygiene but to protect the joint shoulders from breaking off under wheeled traffic such as carts, forklifts and casters.  In this photo we can see what these joints look like once we fill them with a gray semi-rigid joint filler and shave it flush with the floor surface.
