Dry pre-mix made of hydraulic binders, limestone and siliceous aggregates, for easy handling and optimisation of the resistance and anchoring characteristics.
Properties
- Ultra-fast with compensated retraction
- No segregation in the plastic phase
- For indoor and outdoor use
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 (except calibrated and washed gravel)
- Do not apply product that has started to set or softened compounds
- Recommended thickness: minimum 3 cm and maximum 8 cm
- Service-ready in 2 hours
- It is important to respect the water quantities in the mixer to prevent the product from splitting, high shrinkage and reduced resistance
- Due to its expansive nature, it should not be used for levelling free surfaces so as to prevent bubbles or cracks from occurring
Suitable for anchoring metal elements in concrete (cables, bars, reinforcements etc.). Filling of support equipment bases, machine foundations, sewage covers, filling of cracks and confined cavities inside the concrete. Sealing of pipe pass-throughs in concrete walls.
The supports must be dry, prepared, clean and degreased. Dust, efflorescence, release agents and rust must be removed. Absorbent supports must be previously wetted until saturated, avoiding soaking. Mechanically mix 25 kg of the powder product with 14% water (3.5 litres of water per package), with a low-speed electric mixer, until a smooth, lump-free paste is obtained. Pour in the MASFIX immediately after the mortar in order to make the most of its expansive properties and its fluidity. In the case of filling under plates, an inlet and outlet opening must be ensured to facilitate the expulsion of the air.
