Full cure 



It is essential that adequate preparation is carried out prior to the application of SpECtop CPD Primer SF such as grit blasting. The prepared surface should be free from laitance, dust, algae, oil and grease.

SpECtop CPD Primer SF is supplied in 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 entire contents of the curing agent should be emptied into the base component, ensuring that the sides of the curing agent tin are carefully scraped to remove all the material.
The combined materials should then be mixed using a suitable slow-speed drill and mixing paddle for 2 minutes until uniform. The sides of the tin should then be scraped and mixing should continue for a further 2 minutes.

The mixed product may be applied by brush/roller/trowel. The theoretical consumption rate is 5 m2/litre.

When applying SpECtop CPD Primer SF care should be taken to ensure an unbroken coating. One coat should be applied and allowed to gel.
SpECtop CPD Primer SF is supplied in 1, 2, 5 and 15 litre units. The theoretical consumption rate is 5 m²/litre.
