Dry pre-mix made of mixed binders, limestone and siliceous aggregates, adjuvants and reinforcing fibres for easy handling and optimisation of the resistance characteristics.
Properties
- Class R4, pursuant to the requirements of NP EN 1504-3
- Fast-drying thixotropic mortar and compensated shrinkage
Precautions and recommendations
- Do not apply below 5ºC or above 30ºC
- Do not apply when there is a risk of frost, rain, strong winds or direct sun
- Do not mix with other products or fillers
- Do not apply on painted surfaces or plaster
- Do not apply product that has started to set or softened compounds
- Recommended thickness: between 5 mm and 35 mm, per layer
- It is important to respect the water quantities in the mixer to prevent the product from splitting, high shrinkage and reduced resistance
Datasheets(X)
Intended for use in repair systems for concrete with structural damage. Simultaneously carries out the reinforcement passivation, repairing the concrete
structure and obtaining a fine final finish. Apply to horizontal and vertical concrete surfaces, both inside and outside, such as beams, pillars and surfaces with a concrete finish.
Surfaces must be resistant, stable and clean, free from dust, remnants of release agents, paints, organic products etc. Wet the concrete surface beforehand. Rust on reinforcement iron that is crumbling must be removed with abrasive blasting. Mechanically mix 25 kg of the powder product with 16.5% water (4.12 litres of water per package), with a low-speed electric mixer, until a consistent, lump-free paste is obtained. Apply by hand, filling and compacting the area to be repaired, in layers from 5 mm to 35 mm.
