Surface preparation

Surfaces to be treated must be clean, dry and free of all loose material. Wire brushing or sweeping is usually sufficient. Watco Bio-D degreaser can be used if there are spots of oil or grease. If the surface is damp it can be primed with Watco Tack Coat.

The resin content of Watco Concrex® Carbon Fibre 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® Carbon Fibre 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.



Each bucket contains Concrex powder and bottles of curing agent. Mix the two components with a trowel until you achieve a uniform grey colour, you can complete the mixing by using your gloved hands. For large quantities, it is advisable to use a mixer.


Apply the repair mortar to the surface to be repaired and smooth with a trowel. To prevent streaks, wipe the blade with a rag soaked in white spirit.
