Watco Concrex® Carbon Fibre is an ultra-strong, heavy-duty repair mortar designed for long-lasting concrete repairs in high traffic and industrial environments.

Reinforced with carbon fibre and ceramic additives, this epoxy-based system delivers exceptional strength, durability and resistance to impact, abrasion and chemicals. Unlike traditional cement-based repairs, Concrex Carbon Fibre creates a permanent, granite-hard finish that won’t break down under pressure.

With a rapid curing formulation, repairs can be ready for light traffic in as little as 1 hour, making it ideal for busy areas where downtime needs to be kept to a minimum.

Perfect for repairing holes, damaged steps, ramps, joints and worn concrete, this versatile system is suitable for both internal and external use.

✔️ Stronger than traditional cement repairs
✔️ Reinforced with carbon fibre for maximum durability
✔️ Ready for traffic in as little as 1 hour
✔️ Long-lasting, impact and abrasion resistant
✔️ Ideal for thin section and feather-edge repairs
✔️ Suitable for industrial and heavy-duty environments

Limitations

• Do not apply to wet surfaces
• Do not apply thicker than 50mm in one layer
• Not suitable for temperatures above 60°C
• Minimum application temperature: 10°C

Surface Preparation

• Surfaces must be clean, dry and free from loose material
• Remove grease, oil and contaminants using a suitable degreaser
• Wire brushing or sweeping is generally sufficient
• Damp surfaces should be primed with a tack coat primer
• No primer is usually required due to high resin content, unless on smooth or intricate areas
