SpECtop LFC provides a self-levelling, cement
based underlay material for a wide range of floor
finishes including carpets, tiles, vinyl sheet, linoleum
and rubber sheet.
• Pre-measured components giving consistent
performance
• Polymer modified to ensure excellent adhesion
to prepared substrate
• Curing is not generally required
• Easy to lay and excellent early strength grain
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.
