SpECtop SLC is a very low emission floor levelling
compound for producing smooth and levelled
substrates for a wide range of floor finishes including
mineral screeds, concrete, tiles and slabs, natural
stones and terrazzo.
Note: SpECtop SLC to be used in dry areas only. Do
not use as a screed or wearing surface and on
mastic asphalt screeds.
• Self-levelling and pumpable
• Good strength values
Surface preparation
It is essential that adequate preparation is carried
out prior to the application of SpECtop SLC. Surface
should be clean, free from structural defects, firm,
permanently dry, and free of release agents. Light
sweep blasting is recommended to ensure the
removal of all laitance, grease and oil. Always grind
calcium sulphate screeds and vacuum clean.
Priming
Primer is not required generally for a smooth, sound
concrete surfaces. For extremely porous substrates
use one coat of SpECtop SLC Primer at about
100µm wft and allow it to dry for at least 1 – 2 hours
prior to the application of SpECtop SLC.
Mixing
SpECtop SLC is supplied as a one-part floor
levelling compound.
The specified water
quantity should be
measured in an accurately
graduated vessel and
added to the mixer. The
bagged powder is then
added slowly whilst mixing
using a slow speed heavy duty drill fitted with a
suitable mixing paddle (SpEC Technical
Department can advise). Mix for 2 – 4 minutes.
The recommended water used per 25kg bag is 6.25
litres.
Do not mix with other levelling compounds
Application
Pour the mixed product onto the substrate
and spread using a smoothing trowel or spreader.
On non-absorbent mineral substrates a minimum
layer thickness of 2mm must be applied. Protect the
freshly applied compound from direct sunlight
and droughts. Do not use in wet or outdoor areas.
SpECtop SLC is s supplied in 25kg bags with a
coverage rate of 1.5 kg/m²/1mm layer thickness.
SpECtop SLC Primer is supplied in 5 and 20 litre
packs with a coverage rate of 7 – 10 m²/litre.
