Finnseco Valulaasti

Mortar containing a water-reducing agent and cement used as a binder; maximum grain size: 3.0 mm.

Repair of concrete structures, jointing of elements, minor casting such as repairs of top-floor slopes. Recommended layer thickness 10-50 mm. Stress class XF 4, XC 4, XS 2, XD 3 (50 years of planned use time) – XF 3, XC 4, XS 2, XD 3 (100 years of planned use time).

Mineral structures both indoors and outdoors requiring structural strength and good frost resistance.

Ready mix: 12–13 l of ready mix / 25 kg dry product.

The temperature of air, mortar and substrate must be at least +5 °C. Avoid working when it is hot or in direct sunlight.

Old concrete surfaces are cleaned mechanically and pressure cleaned. Moisten the substrate before starting. When starting casting, the surface must be matte damp and absorbent. On smooth and unevenly absorbent surfaces, Finnseco Grout should be used. MIXING THE PLASTER Add the dry material to the water and mix with a whisk or a power mixer for 2 to 3 minutes until the mass is even. Let the mix stand for approx. 5 minutes after mixing, then re-mix. Find the right consistency for the mortar during re-mixing by adding the final amount of water, if necessary. You should not measure the maximum amount of water into the mixing container at the start. The pot life of the mix is approx. one hour.

First coat:

Casting: Adhesion to the concrete substrate is ensured by brushing the running casting concrete firmly on the substrate. The casting is carried out immediately on top of the fresh bonding layer. The thickness of the cast layer with one fill is approx. 10–50 mm. When making thicker castings in several layers, the lowest layer surface is left coarse to ensure good grip. Reinforcements must be used when casting thick, uniform layers.
