surfaces shall be steel trowed unless otherwise stated. Refer to Section 4.16 PATHS AND
PAVEMENTS for top surface treatments to pavement types.

For Class 2 surfaces blow holes greater than 3mm are not permitted. All exposed surfaces
shall be even and true to shape, free from mortar fins, form marks or other irregularities. All
Class 2 surfaces shall be protected from staining due to mortar runs or splashing,
reinforcement exposure, timber or curing processes.

Any staining to surfaces exposed to view shall be removed by rubbing with a carborundum
block and water until a uniform textured surface is achieved. The paste formed in the
process is to be rubbed off after drying with a dry hessian or canvas.

Plastering and mortar capping to concrete will not be permitted.

6.7.2 UNIT PAVING
Supply and install paving as indicated on the drawings.

Pre-cast Concrete Pavers: All Concrete Pavers shall be sound with straight, sharp arises,
free from distortion and other defects. Pavers shall be of uniform texture and coloured to
match concrete as scheduled. Concrete Pavers shall be cured for at least 28days and shall
conform to the dimensions specified in the Paving Schedule. All Vehicle Grade Pavers to be
installed to Engineers Specification.

6.7.3 BROOM FINISHING

Wood float and broom, using a moistened nylon broom 500 mm wide, across the pavement
to give an even textured slip-resistant surface with steel tooled margins. On gradients
steeper than 10% roughen the surface by scoring across the slope at 50 mm centres.

6.7.4 EXPOSED AGGREGATE

Apply water-based surface set-retarder to formwork. Remove the forms while the concrete
is green. Wet the surface and scrub using stiff fibre or wire brushes, using water freely, until
the surface film of mortar is removed without the use of acid etching, and the aggregate is
very lightly and uniformly exposed. Rinse the surface with clean water. Cure surface
following exposure of the aggregate, curing regime may be an applied spray membrane or
wrap plastic
