Mapei Mapegrout Fast-Set - Fibre-Reinforced Repair Mortar
Rapid-Setting, Fibre-Reinforced Repair Mortar for Structural Concrete Restoration
Mapei Mapegrout Fast-Set is a high-performance, rapid-setting, fibre-reinforced, shrinkage-compensated cementitious repair mortar designed for structural concrete restoration. Formulated for horizontal and vertical repairs, it allows traffic or further work just hours after application, making it ideal for time-sensitive civil engineering, infrastructure, and industrial flooring projects. Suitable for thicknesses from 10mm to 70mm in a single layer.
Key Features & Benefits
- Rapid Strength Gain: Ready for light traffic in 2–3 hours, and heavy traffic in 24 hours.
- Fibre-Reinforced: Enhanced crack resistance and structural integrity under load.
- Shrinkage-Compensated: Minimises cracking and ensures dimensional stability during curing.
- High Mechanical Strength: Excellent compressive and flexural strength for long-term durability.
- Multi-Surface Application: Suitable for floors, ramps, roadways, loading bays, and pre-cast units.
Product Details
- Type: Rapid-setting, fibre-reinforced cementitious repair mortar
- Form: Grey powder
- Packaging: 25kg bags
- Layer Thickness: 10mm to 70mm in a single layer
- Pot Life: Approx. 15–20 minutes at 20°C
- Foot Traffic: After 2–3 hours
- Heavy Traffic: After 24 hours
- Compressive Strength: > 50 MPa at 1 day
- SKU: MAPFAST25
Application Instructions
- Substrate Prep: Clean and roughen concrete surface. Remove all deteriorated material, dust, oil, and contaminants.
- Mixing: Add 3.5–4.0 litres of clean water per 25kg bag and mix with a mechanical mixer until smooth and lump-free.
- Application: Apply with a trowel or float in one layer up to 70mm. Compact well to ensure full adhesion.
- Finishing: Smooth the surface as required. Protect from rapid drying and rain during initial curing.
Limitations
- Not suitable for pours deeper than 70mm in a single layer — apply in successive layers if needed.
- Do not add cement or admixtures.
- Do not apply at temperatures below +5°C or above +35°C.
Health & Safety
Contains cement — avoid skin and eye contact. Use appropriate PPE such as gloves, goggles, and dust mask. Refer to the Safety Data Sheet (SDS) for full safety information.
