Structural, fibre reinforced fluid mortar for very low thickness screeds

Code: FLR.0052

Components: 1

Appearance: Powder

This rheoplastic, composite cementitious grout with controlled-shrinkage and super-fluid consistency is fibre-reinforced with a special mix of glass and polypropylene fibres, having a base of high-strength cements, polymeric modifiers, anti-shrinkage agents, super-pozzolanic reactive fillers and selected siliceous aggregates. Ideal for restoring the thickness of concrete removed by milling, of old concrete flooring (with a reconstruction thickness from 15 mm to 40 mm), along with dimensional adjustments, structural reintegration and so on.

Use fields

Repair and cladding industrial concrete floors, structural restoration, dimensional adjustments, increases in the resistant section, reconstruction of the thickness of the concrete removed by milling, etc.

Preparation of supports

The surfaces of application should be clean and free of any soiling, crumbling and non-adhering parts, dust, etc., saturated with water.

In the case of surfaces to be rebuilt after milling, the areas of reconstruction will have to be in as regular a shape as possible (as similar to a square as possible); the thickness should be as homogeneous as possible; finally the section of the pre-existing flooring to be filled should be reminiscent of the shape of a trapezium which widens toward the bottom (this is in order to anchor the "patch" perfectly in the seat of reconstruction and to avoid its detachment, given the slightly expansive properties of the product).

Use method

It is necessary to provide a suitable bonding bridge between the part to be reconstructed and the reconstruction material. There are 2 alternative ways of doing this:
- Roll out the specific epoxy primer on the prepared surface, using a roller or a brush, for structural construction joints SYNTECH RGS.
- Prepare adequate additional reinforcement, parallel to the bottom of the reconstruction, consisting of electrowelded mesh (2 mm wire, 5x5 cm mesh) at a distance from the bottom of half the thickness, attached to the bottom itself by "L"-shaped steel bars, with improved adhesion and a diameter of 8 mm, inserted in holes and secured by expansive cement micro-mortar GROUT MICRO-J or polyester resin in a two-compartment extrudable cartridge PROFIX.

For the preparation of the mortar insert 2/3 of the total mix water in the mixer, gradually add the product and the remaining water, until you obtain a uniform mix of the desired consistency. Pour the mixture prepared in the seat of reconstruction, prop it up and level it until it is perfectly smooth.

Warnings, precautions and Ecology

Do not apply with direct exposure to sunlight and/or in ambient temperatures below +5°C; cure the protection and the prolonged moist hardening of exposed surfaces.

Do not use restoration for at least 4 days after their completion.
