  • Repels most common graffiti attacks (washes off with water and detergent).

Components (in order of application):



  • SWT Corrosion Primer: Two-part epoxy comprising the primer (part A) and the hardener (part B). Rust and wet tolerant for application to all metal fixings such as hook bolts to prevent rust from breaking through the coating.
  • MetalSeal 20: Permanent coating system for external refurbishment of metal profile roof systems.

Applications:

Suitable for the following:



  • Refurbishment of metal profiled roofs.
  • Use as a cladding coating system: When applied to vertical cladding, the system provides a highly effective barrier against graffiti.

Approvals:

- SWT Corrosion Primer:



  • International Maritime Organization (IMO) approved.
  • Lloyds Ballast Tank Maintenance Coating approval: New Build Applications (bore steel and shop primers).

- MetalSeal 20:

BBA certified.

Surface preparation:

In most cases, MetalSeal 20 will be applied directly to an existing, aged coating or factory finish. In cases where substrate delamination is apparent, the existing substrate must be removed by one of the following methods:



  • 3–4000 psi pressure wash with turbo lance.
  • Vapour blasting using appropriate Quill Falcon Kwikblast system.

Manufacturer recommends the use of Xylene for washing brushes after the application of the MetalSeal 20 component.

Consult manufacturer's literature for further details on spray application guidelines.
