Priming

A primer is not usually required when filling holes in concrete floors or resurfacing rough or damaged concrete.

Watco Tack Coat Sub Zero adhesive primer is recommended when using Watco Concrex Sub Zero as a thin section screed over smooth surfaces.

It is also recommended when repairing intricate/high impact areas such as broken floor joint edges and damaged step nosings.

Mixing

Wear protective gloves.

Each pack contains one tin of curing agent, one tin of resin and a blended aggregate.

Tip the blended aggregate onto a mixing board. Empty the contents of the small tin into the larger tin and mix together thoroughly.

Empty the mixed components onto the aggregate and mix using a trowel. The more thorough the mixing, the ’wetter’, smoother and more manageable the mix becomes. Alternatively, you can knead the mixture by hand wearing suitable gloves.

It is important to mix thoroughly until you achieve a consistent colour.

Application

Trowel the mortar firmly into the repair and finish with a trowel or float. To get a good, smooth finish, regularly wipe the surface of the trowel with a cloth dampened with white spirit.

Watco Concrex Sub Zero is normally applied at 5mm - 50mm thick, but repairs can be feather-edged if most of the repair is at least Smm thick. For repairs deeper than 50mm apply in separate layers allowing each to cure before the next is applied.
