The compound shall be applied by spraying with pressure tank equipment having provision for continual
agitation of contents during application. Where forms are removed during the curing period the exposed
concrete shall be lightly sprayed with water and such moistening continued until the surface will not
readily absorb more water, and as soon as the moisture film has disappeared the curing compound shall
be applied to the concrete surface.

6.12 Surface Finish

All concrete surfaces shall be true and free from stone pockets, depressions or projections beyond the
surface. All arrises shall be perfectly sharp and true and all mouldings evenly mitred. Care shall be
exercised in removing forms to ensure this result. As soon as the forms are removed, all rough places,
holes and porous spots shall be repaired by removing defective work and filling with stiff cement mortar
having the same proportions of cement and sand as was used in the concrete, and brought to an even
finish.

Bolts shall be removed and the cavities filled as described in Clause “ Formwork”

Concrete surfaces shall comply with the following classes set out in Australian Standard AS 1510 Part 1.
Contro! of Concrete Surfaces - Formwork or as required below.

» Formed exposed surfaces - Class 2
» Formed backfilled surfaces - Class 5
» Top Surfaces - steel trowel

For Class 2 surfaces blow holes greater than 12 mm 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 Class 2 surfaces not complying with this standard are to be brought to a smooth even textured finish
by bag rubbing and grinding as required.

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.
