Surface preparation
It is essential that adequate preparation is carried out prior to the application of SpECtop LFC. Light sweep blasting is recommended to ensure the removal of all laitance, grease and oil.

Priming
The substrate must be primed using SpECtop LFC Primer at the rate of 5-7 m²/litre. On very porous substrates it may be necessary to apply a second coat of primer if absorption is noted to be high. The primer/sealer must completely seal the floor or air release will cause bubbles to form in the SpECtop LFC.

Allow the primer to become touch dry.

Mixing
SpECtop LFC is supplied as a two component pack consisting of a liquid component and a powder component.
Add approximately 50% of the liquid component to a clean 25 litre steel drum and gradually add the powder whilst mixing using a slow speed heavy duty drill fitted with a suitable mixing paddle (SpEC Technical Department can advise). Mix for 2 minutes. Slowly add the remaining liquid whilst mixing and continue mixing for a further 2 minutes.

Application
Pour the mixed product onto the primed substrate and spread using a squeegee or a pin screed. The material must then be rolled using a spiked roller with spikes of a length greater than the depth to be laid. There should be no delay between levelling the product and spike rolling. Troweling is not required. For large areas good site organisation is essential and the use of a grout pump may prove beneficial. SpEC Technical Department can advise of the types of pump available.
SpECtop LFC is supplied as a two product component weighing 21.6kg with a yield of 11 litres.

SpECtop LFC Primer is supplied in 5 and 20 litre packs with a coverage rate of 5 m²/litre.
