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. 


A primer is not usually required if patch or crack repairing. Watco Tack Coat adhesive primer is recommended when applying Watco Concrex as a thin section screed or when applying to smooth, non-porous or metal surfaces.

Mixing and application

Each Watco Concrex pack contains a granular resinous compound and separate containers of curing agent. Concrex Sub Zero has 3 components; resin, aggregate and curing agent. The components are mixed with a trowel according to the simple instructions in the pack until a smooth grey mortar is obtained. The more thorough the mixing, the ‘wetter’, smoother and more manageable the mix becomes. This can be achieved quite quickly by wearing disposable gloves and kneading the mixture by hand. A creteangle or similar mixer can be used to ensure thorough mixing of larger quantities. This is trowelled firmly against the surface to be repaired, and finished with a trowel or float. To prevent drag on the trowel, a rag moistened with white spirit may be wiped across the face of the tool.
