The number one epoxy resin floor repair mortar on the market

The only concrete repair mortar embedded with carbon fibre particles

A premium epoxy resin mortar designed to permanently repair damaged concrete floors

Following extensive research and formulation development, we've launched our best ever epoxy repair mortar, Concrex Carbon Fibre. The improved repair mortar has joined the extensive Concrex range, replacing the bestselling original formulation to achieve even greater results.

Concrex Carbon Fibre is a premium epoxy resin mortar designed to permanently repair damaged concrete floors. The carbon fibre and ceramic based formulation is now even stronger, more chemical resistant and dries even faster.

The benchmark product when it comes to repairing concrete floors

Simple to use, it's already part mixed with the resin and aggregate combined, further reducing preparation time. Simply add the grey activator to the mix (this is coloured to help users ensure it is sufficiently combined) and the product is ready to go.

  • Extremely rapid curing
  • Enhanced abrasion resistance
  • Feather edge or intricate repairs
  • Suitable for use at temperatures as low as 10ºC
  • Stronger than cement based alternatives

Incredibly versatile and durable

Concrex Carbon Fibre is versatile enough for use across a wide range of environments. It can be used virtually anywhere an ordinary mortar might fail, including holes, guide rails, ramps, steps and spalled joints. The revamped mortar can also be 'moulded' into shape to form a kerb and even repair step nosing. Most repairs using Concrex Carbon Fibre require no primer but it can be used with Watco's Tack Coat for intricate repairs, or thin screeding jobs.

Application

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.

Mixing

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.

Application

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.
