CPC 500 SA is a black, quick drying, low viscosity primer for concrete, asbestos cement, brick and similar masonry surfaces. It is also an effective primer on metal surfaces such as steel, galvanised sheeting, aluminium etc.

After drying it leaves a non-sticky surface at normal air temperatures.

SPECIAL CHARACTERISTICS
A high percentage of rubber latex imparts considerable elasticity to the dried film.

SURFACE PREPARATION
Remove all dust, dirt and rust. Remove excess loose or powdery material with a stiff brush or broom. Cementitious surfaces must be free or laitance. Where moss and lichen etc are present, this should be removed using FC Clean, and the surface treated with fungicide which should be allowed to dry before the CPC 500 SA treatment proceeds. Stir contents of tin before use.

APPLICATION
1) CPC 500 SA can be sprayed or applied with a soft brush. The coverage per litre on average masonry surfaces will be approximately 3-4 m2.
2) Drying time will be approximately 3-4 hours at 20oC. At the end of this period the surface will be touch dry, but the surface should be allowed to dry for 24 hours before applying waterproofing or sealing compounds, as solvent entrapment will lead to poor adhesion.
3) A second application is recommended to waterproof porous surfaces and to provide a thoroughly durable covering. Each coat must be dry before the next is applied. Drying time will be approximately 3 - 4 hours in sunny weather.
4) Brushes or brooms should be washed in clean water immediately after use; if clogged, they can be cleaned with paraffin or white spirit. These solvents should not be used on brushes or brooms during application.
