Surface Preparation
The substrate must be firm, able to bear sufficient loads and have adequate grip. It must be free of grease, oil and non-adherent components. It must also be free of any layers or contaminants that could reduce the adhesion.
Remove non-adherent layers and contaminants by suitable mechanical means (e.g. shot blasting, milling or sanding). Then remove all dust using an industrial vacuum cleaner. Larger repairs and the filling of gaps, holes and other unevenness must be carried out with SpECbuild repair materials.

Priming
Highly porous substrate needs to be primed with SpECtop Primer F1, SpECtop Primer FX or SpECtop Scratch Coat binder at O.1 to 0.2 L/m2 rate.

Application
Stir base thoroughly. Add hardener and mix for at least 1 minute with an electrical mixer (speed 300 – 400 rpm). Add the filler and mix again for 2 minutes. Pour the mixture onto the surface and distribute using a smoothing trowel.

SpECtop Scratch Coat is supplied as a three product component weighing 15 litre units.
