Single‐ component, permanently flexible protective and anti‐carbonization paint for concrete

Product Characteristics
Single-component, permanently flexible protective coating based on aqueous styrene-acrylate polymeric dispersion of fine-grain mineral fillers, special additives and pigments. Meets the requirements of EN 1504-2

  • supplied as a single-component product
  • has excellent workability, can be applied by brush a roller or a spray gun
  • has enhanced carbon dioxide penetration resistance
  • highly flexible and ductile even at temperatures below zero
  • has the ability to overlap cracks in the base
  • permanently UV radiation resistant
  • waterproof
  • permanently frost resistant
  • perfect adhesion to base

FLEXICOAT is a single-component, permanently flexible, waterproof painting material intended especially to protect concrete and reinforced concrete from atmospheric effects and carbonization. It provides good protection for dynamically loaded concrete structures and to protect and repair surfaces damaged by growing hairline cracks. After curing, it provides permanent resistance to water and all atmospheric effects, shows excellent resistance to UV radiation.

Instruction for preparation and application
The base must be adequately cohesive, free of impurities and possible residual degraded coatings. Local defects should be filled in. Local uneven spots of the surface should be free of sharp edges.

Preparation of the paint FLEXICOAT is supplied as a single-component system. Its preparation for application consists simply of mixing with a suitable manual mixer or a slow-speed electric propeller mixer. The mixed material should be protected from drying by sealing the bucket.

Application The paint is applied to a suitably prepared substrate with a brush, roller or spray gun in two layers. In dependence on absorbance and moistness it is desirable to use FLEXICOAT fixativ for the base penetration. Dry and absorbent substrates require penetration. Interval between applying next layer should be at least 12 hours. The paint is drying out for about 4 hours.
Neither temperature of the base nor temperature of ambient air shall be below + 5 °C and above + 35 °C.

Specific consumption For standard two-layer coating system the spreading capacity (specific consumption) amounts to 0.3 – 0.6 kg/m2, while final thickness of the coating should be ca. 150 – 200 µm.
