Full exposure is where the Floor is ground to show maximum amount of aggregate as possible. If the slab has been pumped fairly wet as in floors poured for the purpose of floor coverings the stones will not be near the surface hence more grinding.

Concrete Requirements- Concrete needs to be preferably 25 mpa of strength or higher and well cured. No vibrator is to be used in the top 100 mm of the Concrete slab so to minimise areas with no stone. Also care has to be taken when laying the Concrete eg- Screed Marks, Foot Prints etc. because of the risk of pushing the aggregate down too far. Steel float finish. No need to run the helicopter over the top as it makes the top too hard too grind which comes off anyway.

Random Exposure, this is where the floor goes from nil exposure to full exposure of aggregate.

Concrete Requirements- Concrete needs to be preferably 25 mpa of strength or higher and well cured. Vibrator can be used with this throughout the whole slab. Also care has to be taken when laying the Concrete eg- Screed Marks, Foot Prints etc. because of the risk of pushing the aggregate down too far. Steel float finish, no helicopter. This Floor would be the most popular out of them all.

Salt and Pepper, this is when the concrete is ground lightly to expose the sand and tips of the aggregate.

Concrete Requirements-Concrete needs to be preferably 25 mpa of strength or higher. Vibrator should be used and floor should be as flat as possible. In regards to this floor the concrete should be left with a burnished finish by a helicopter so it is completely smooth.

Cream Finish, this is where the floor has nil exposure, but occasionally a salt and pepper finish on high spots

Concrete Requirements- Concrete needs to be 32 mpa strength or higher and well cured. The concrete has to be completely flat and hit with the helicopter to achieve a burnished finish multiple times so it leaves the concrete completely smooth
