There are three types of finishes available

Type A finish

The finish surface should be free from voids, honeycombing and other blemishes, small blemishes caused by entrapped air or water may be visible.

Type B finish

This finish can only be obtained by the use of high quality concrete and formwork. The concrete is thoroughly compacted and all surfaces are true with clean arises. Only very minor surface blemishes occur with no staining or discolouration.

Type C finish

This finish is first obtained by producing a type B finish and then improving this finish by carefully removing all fins and other projections, thoroughly washing down and then filling the most noticeable surface blemishes with a cement and fine aggregate paste to match the colour of the original concrete. After curing, the face is rubbed down, where necessary, to produce a smooth and even surface.
