Surface protective intervention.

Protective intervention

The surface shows no degradation, protective intervention to extend the life of the work.

Degraded concrete.

Degraded concrete.

When the concrete surface shows no degradation, a protective coating is applied. 
The protective coating ResinFIP COAT PU 370 EL must always be applied after the concrete substrate has been treated with the special primer ResinFIP Primer 371 indicated for dry substrates with a maximum moisture content of 4%, in the absence of capillary rising damp, 0.15 ÷ 0.30 kg/m2 the theoretical consumption varies depending on the roughness of the substrate.

Intervention with two coats of paint

Intervention with two coats of paint

Application of two coats of paint with a film-forming, rigid, single-component, acrylic resin-based protective system in water emulsion for the protection of reinforced concrete structures not in permanent contact with water.

BetonFIP TIXO

BetonFIP TIXO

Intervention with skimming or surface spraying restoration with cement mortar, thixotropic, premixed, expansive in air, resistant to aggressive agents in the environment, designed to restore, repair, reinforce degraded concrete structures.
Requires application of contrast reinforcement for thicknesses greater than 30 mm.

ResinFIP COAT 350 EL

ResinFIP COAT 350 EL

Protective intervention with two coats of paint with a film-forming, elastic, single-component protective system, based on elastic acrylic resin in water emulsion, for the protection of concrete structures.

Medium degradation with centimetric interventions

When the surface of the concrete does not show any deterioration, a protective paint is applied, otherwise levelling is carried out with specific mortars.

BetonFIP TIXO F

BetonFIP TIXO F

Intervention with skimming or surface spraying restoration with cement mortar, thixotropic, premixed, expansive in air, resistant to aggressive agents in the environment, designed to restore, repair, reinforce degraded concrete structures.
Requires application of contrast reinforcement for thicknesses greater than 30 mm.

ResinFIP COAT PU 370 EL

ResinFIP COAT PU 370 EL

Intervention with two coats of a film-forming, elastic, two-component, solvent polyurethane resin-based protective system for protecting concrete structures.

Deep degradation

When the surface of the concrete shows deep degradation, the reinforcement rods are treated and the missing parts are reconstructed by pouring medinte cassaro, then two coats of paint are applied.

BetonFIP FLUID REINFORCED

BetonFIP FLUID REINFORCED

Restoration by bonding with formwork with cement mortar, pre-mixed, pourable, expansive in air, fibre-reinforced with rigid steel fibres, ductile, high flexural strength, resistant to aggressive environmental agents, designed to restore, repair, reinforce concrete structures. It does not require the application of contrast reinforcement.

ResinFIP FLUORUR COAT

ResinFIP FLUORUR COAT

Application of two coats of paint with a film-forming protective system with a fluorinated polyurethane resin finish to protect concrete structures from the aggression of environmental agents and de-icing salts. It can be applied by brush, roller or spray using an airless system, creating a film-forming coating that forms a barrier to the ingress of aggressive substances.
The protective system includes:

ResinFIP PRIMER 391 primer silossanico in emulsione acquosa, antisale, trasparente;
ResinFIP COAT AC PU 392 two-component, water-based, acrylic-polyurethane primer intermediate coat, coloured;
ResinFIP COAT F PU 390 two-component, grey-coloured, fluorinated polyurethane resin-based top coat.
