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, all the ingredients to get a homogeneous paste.

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