Surface Preparation
Surfaces to be treated must be dry, sound, free from oil or other contaminants, loosely adhering coatings, laitance and dust.

The prepared surface should be primed with SpECtop Primer F1.

The contents of the curing agent should be emptied into the contents of the base component and stirred with a spatula until the product appears uniform.

The mixed primer should then be applied to the prepared substrate by a stiff brush at 10-15 m²/litre. Do not over apply.

If the primer appears to be absorbed into the surface easily, it will be necessary to apply a second coat once the initial coat is tack-free.

Allow the primer to become tacky prior to applying SpECtop PU500.

SpECtop PU500 is supplied as a two-component kit consisting of a base component and a curing agent.

Both of the components should be briefly stirred to ensure that any settlement products are fully suspended.

The most convenient method of mixing is by using a slow speed, heavy-duty electric drill.
Empty the entire contents of the curing agent into the base component. To ensure that all material is extracted, the insides of the tins should be scraped. The curing agent and the base component should be mixed with a slow speed, heavy duty electric drill and a spiral mixing paddle for at least five minutes and until the material appears uniform in colour and consistency.

Apply the mixed product either directly on the tack-free primer, depending on the system requirements. The product may be applied between 200 and 500µm using a squeegee, roller or brush.
SpECtop PU500 is supplied in 4.5 litre and 15 litre pack and covers 4 m²/litre depending on surface texture.
