Surface Preparation


Surfaces should be clean, dry, and free of all loose material. Wire brushing or sweeping is generally sufficient. Watco Bio-D degreaser can be used to remove grease and oil. If the surface is damp, it can be primed with Watco Tack Coat.



Priming


The resin content of Watco Concrex Cold Set is very high. This means that a primer is not usually required when filling holes in concrete floors or resurfacing rough or damaged concrete.

Watco Tack Coat adhesive primer is recommended when using Concrex Cold Set 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. Watco Tack Coat can also be used at the same low temperatures as Concrex Cold Set.

Watco Concrex Cold Set should ideally be applied to a dry surface, but if the surface is damp Watco Tack Coat should be used as a primer.



Mixing


Wear protective gloves.

The resin and the sand are already pre-blended. There are 4 bottles of grey curing agent supplied with a 10kg unit of Concrex Cold Set, and larger bottles of grey curing agent in the 25KG packs.

The curing agent is added to the sand/resin at point of use, and once mixed the mortar should be used within 30-60 minutes depending upon temperature.

Do not mix inside the plastic bucket. Tip the sand/resin into a mixing tray or on a board.

Shake the bottles of curing agent until the liquid is a uniform grey. The tins of coloured curing agent should be stirred thoroughly.

Form the sand/resin into a mound and leave a small hole in the middle. Empty the curing agent into the hole, ensuring the tin is completely drained.

Carefully mix the aggregate with the curing agent using a trowel until a smooth mortar is obtained, this will take several minutes. 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. A ‘Cretangle’ or suitable open pan mixer can be used to mix large quantities.



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 Cold Set/Colours Cold Set are normally applied at 5-50mm thick, but repairs can be feather-edged if most of the repair is at least 5mm thick. For repairs deeper than 50mm, apply in separate layers allowing 6-8 hours between layers, or use Watco Concrex Deep Fill Cold Set which can be applied at 15-100mm thick in one layer.



Limitations


Do not apply to wet surfaces.

Watco Tack Coat should be used for application to damp surfaces before applying Watco Concrex Cold Set.

Please refer to Watco Tack Coat data sheet for further information.

These products should not be subjected to temperatures above 60°C.
