Surface Preparation
It is essential that adequate preparation is carried out prior to the application of SpECtop HF.

Grit blasting is recommended and must result in the removal of all laitance, grease and oil. The resultant surface should be dry and dust free.

Priming
The prepared surface should be primed with SpECtop Primer FX.

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 10-15m²/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 HF.
Mixing
Pre-mixing of the coloured liquid component is recommended to ensure any light settlement is re-dispersed. Thoroughly scrape the contents of the liquid colour component into the brown hardener component and mix for a minimum of 1 minute or to provide a homogeneous mix. The resultant mixture should then be loaded into a rotary drum mixer and the aggregate component added in stages, mixing until a lump free consistency is obtained. Apply to pre-primed areas and level with a pin rake as necessary and lightly touch up with a trowel.

Application
Immediately after mixing apply SpECtop HF. Spread out using a trowel and finish using a medium pile roller. Ensure product is not allowed to pond over the blinded substrate to ensure an even textured finish is achieved. Coving can be formed using SpECtop HF Coving Mortar.
SpECtop HF is supplied in a 29.64kg unit with a coverage rate of 18kg/m² at 9mm or 12kg/m² at 6mm.
