Application

Surface preparation requirements before application

  • Previously applied layers must be cured (in accordance with TDS – minimum overcoating intervals), clean, dry, and free from contaminants such as dust, grease, salts, or ice.

Characteristics

The Protelack SFP system consists of:

  • anti-corrosive primer,
  • intumescent fire protection coating,
  • solvent-based topcoat.

System characteristics:

  • High fire resistance.
  • Suitable for both internal and external applications.
  • High-quality finish with RAL color options.
  • Can be applied on steel already primed with other epoxy primers without removing them, reducing project costs.
  • Provides fire protection of open steel profiles up to class R120 and closed profiles up to R90.
  • For external applications (X), the system must be finished with Protefilm T polyurethane topcoat at 120 μm thickness.
  • For internal applications (Z1), the system may be used without a topcoat – the intumescent coating in white fits well in interiors.
