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.

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.
