For steel & mild steel

Rust Shield®

Moisture & rust protection coating

Block moisture. Stop rust. Protect steel.

For steel door frames, steel window frames, truss works and structural steel components. RUST SHIELD lays down a tough moisture-blocking barrier that keeps water off the metal, and where water cannot reach steel, rust cannot start.

Product description

No water on the metal, no rust

PRIME GUARD RUST SHIELD is a high-performance protective coating formulated for steel door frames, steel window frames, truss works and structural steel components.

The advanced formula creates a durable moisture-blocking barrier that helps prevent water and moisture reaching the metal surface. By reducing moisture exposure, RUST SHIELD helps protect steel against rust, corrosion and premature deterioration.

It is ideal wherever metal components come into contact with walls, concrete and masonry, or are exposed to humid environmental conditions.

How Rust Shield works

  • Steel surfaces are vulnerable to moisture penetration, which is what leads to rust formation and corrosion in the first place.

  • RUST SHIELD forms a tough protective coating on the metal, creating a moisture-resistant barrier that reduces water and moisture contact with the steel.

  • That protective layer helps minimise rust formation, guards against corrosion and extends the service life of every steel component.

Recommended applications

  • Steel door frames
  • Steel window frames
  • Truss works
  • Mild steel structures
  • Fabricated steel components
  • Wall contact areas
  • Structural steel members
Rust blooming out of the joint where an uncoated steel window frame enters masonry, lifting the render
Corrosion expands as it grows, cracking render and staining the wall.

Directions for use

De-rust first, then two coats

  1. 1

    Clean the steel

    The surface must be clean, dry and free from dust, grease, oil, rust and loose particles.

  2. 2

    Remove existing rust

    Take off any existing rust with a wire brush, sandpaper or another suitable cleaning method before coating.

  3. 3

    Stir, then apply the first coat

    Stir the product thoroughly, then apply an even coat, including the contact area between the wall and the metal frame.

  4. 4

    Wait 2–3 hours, apply the second coat

    Allow the first coat to dry for 2–3 hours, then apply the second coat.

  5. 5

    Cure, then install

    Wait 5–8 hours for a hard dry. Install or finish the frame only after the coating has properly cured.

Do not

  • Apply on wet surfaces.
  • Coat over loose rust or mill scale.
  • Install the frame before the coating has cured.
  • Leave the container open between coats.
