So, what’s the difference between terrazzo and polished concrete? The difference between terrazzo and polished concrete is the cement-to-aggregate ratio. That’s probably the biggest difference anyway.
Cementitious terrazzo is minimum 70 percent marble-chip material and 30 percent cement matrix (with a Portland cement binder). This is pretty much the opposite of regular concrete, which is around 70 percent cement (including fly ash or slag) and 30 percent aggregate (sand and rock).
When placed, terrazzo is poured and troweled about 1/2-inch thick over a low-strength concrete bed. It is then ground flat, honed, and sealed with a penetrating solvent-based sealer.
Terrazzo must be waxed to achieve the shine that the owner is expecting. With polished concrete, we produce the shine with our diamonds, not through an applied wax finish. We also use densifiers to make the floors harder and more abrasion resistant. With terrazzo, we do not.
Will it feel different to us when we grind and polish terrazzo? The main difference when working on terrazzo is that it’s like grinding and polishing an exposed aggregate floor, not a sand or cream finish like on a regular, power troweled surface. Once those specific differences are understood, and we start with the right diamond grit, the grinding, honing, densification, polishing and stain protection application will be similar to a polished concrete job.
Recently, I spoke to the head of building maintenance at a major university that has more than 3 million square feet of terrazzo. He could spot the difference between terrazzo and polished concrete pretty easy! He had the following complaints about his existing floors:
- The floors are very high maintenance in terms of labor, time and cost.
- The floors are always dull and hazy looking due to increased wax buildup.
- Waxing and stripping is not a very “green” way of maintaining our buildings.
The idea of maintaining terrazzo using our polished concrete techniques was music to his ears! He could definitely see the difference between terrazzo and polished concrete.
Concerns about polished concrete seem to be centered on how slip resistant they are and the lifetime maintenance cost. A natural polished floor (with no wax required) looks clear and shiny, and everyone knows that shiny floors are extremely slippery, right? This very common misconception can be handled by walking into your local Lowe’s, Home Depot or Walmart stores. These particular floors show that polished concrete has more slip resistance than waxed terrazzo floors. Take a look the next time you’re in there and you’ll be sold on polished concrete. The difference between terrazzo and polished concrete is simple.
The overall outcome of polished concrete over terrazzo will be a better looking, higher performing and lower cost floor. The difference between terrazzo and polished concrete starts to become a little more clear. What are some other benefits of polished concrete vs terrazzo?
- There’s no longer a need to purchase products to wax and strip your floors.
- You’ll no longer have pay for labor to have your floors stripped and waxed.
- You’ll enjoy the reduced maintenance costs due to faster daily or weekly maintenance.
