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.


New Watco Concrex® Carbon Fibre is the ultimate floor repair mortar. The addition of carbon fibre makes this the strongest, longest lasting floor repair mortar that you can buy.

The unique formulation also includes a rapid setting curing agent for even faster repairs, and Novolac resin for superior chemical resistance - cement based repair mortars have no resistance to acidity. Abrasion resistance is greatly enhanced by the addition of a ceramic additive. Compared with other repair mortars this formulation is particularly rich in epoxy resin. This provides superior strength and adhesion, making it ideal for very thin section, feather-edge or intricate repairs.

The new rapid cure formulation keeps downtime to a minimum in busy areas, with light traffic possible in as little as an hour. Use in heavy wear areas where other repair mortars would fail - make your floor repairs permanent with Watco Concrex® Carbon Fibre.
