Surface Preparation:
As with all epoxy resin systems, surface preparation is of prime importance. For concrete surfaces, remove all grease, oil, dust, laitance etc. Ensure substrate to receive the screed is sound, cut back to sound surface wherever necessary.

Remove dust and ensure the surface is dry. Prime with Perma Master Prime-CN / Perma Master Bond.

Mix in a suitable pan type of a mixer consisting of 720 gms Base and 280 gms of Reactor components and to this add and mix 2 Kg quartz ball mill powder and quartz sand 30/80 in 1:1 proportion. Mix in a suitable pan type of a mixer.

Perma Master Patch-NS mortar thus prepared looks like a stiff paste. Apply the mixed Master Patch-NS mortar onto the primed surface while it is still tacky, and feather edge it to restore the original shape of the structural member.


A mix of 1 kg of base & reactor with 2 Kg of quartz mix (i.e. 1 kg of ball mill powder and 1 kg of 30/80 quartz sand) gives an epoxy non slump mortar of 1.5 litres. This covers an area of about 5 Sq. ft. if applied to a thickness of 3 mm.
