Klondike Corten — Application Guide

What Klondike Corten is

Klondike Corten is a decorative system that recreates the warm rust, mineral depth and patina of Corten steel. Curated by Italian Surface Finishes for the UK market, it offers a controlled, repeatable way to achieve premium rusted‑metal feature walls in hospitality, retail and contemporary homes.

The system can be worked in different choreographies — from trowelled “plate” readings to vertical Dripping effects that recall rain‑run weathering on steel façades. This guide focuses on the UK‑approved sequence for interior walls.

Step‑by‑step method

1. Prepare the substrate
   Ensure the surface is sound, smooth and clean. Fill cracks and imperfections, sand to a uniform level and remove all dust. For rough blockwork or render, apply Rasante R7 as a levelling coat where specified, and allow to dry fully.
2. Apply the primer / undercoat
   On smooth or Rasante‑levelled surfaces, apply Primer 1200 (or the system‑specified primer) with roller to regulate absorption and create a uniform base. Allow to dry fully according to the technical sheet.
3. Roll on the Corten basecoat
   Apply the Klondike Corten basecoat in the selected reference colour using a short‑pile roller, working corner‑to‑corner for an even film. This layer strongly influences the final Corten tone. Allow to dry thoroughly.
4. Apply the Corten effect coat(s)
   Depending on the desired effect:
   • Spatolato (trowelled) effect: apply Klondike Corten with a flexible stainless trowel in overlapping strokes, compressing to create trowelled plate‑like panels with subtle directional movement.
   • Dripping (Colato) effect: build the effect in two coats, using brush and trowel to create vertical “rain‑run” streaks and deeper rust transitions.
   Work wet‑on‑wet across each wall and feather edges while still open to avoid visible joins.
5. Refine and balance
   While the Corten coat is still workable, adjust pressure and stroke direction to balance warm/cool oxidation patches and achieve the desired movement and patina. Stand back regularly to assess the composition across the entire wall.
6. Optional protective sealer
   In kitchens, commercial interiors or where additional durability is required, apply the specified clear sealer (e.g. Vetro Opaco/Lucido or system equivalent) after full curing. Follow the data sheet with regard to dilution, coats and drying intervals.

Professional tips

• Plan for a slightly vertical bias in movement to mirror real weathering patterns on steel.
• Keep the trowel edge clean; any burrs or dried product will leave unwanted scratches or lines.
• Vary pressure and angle to move between matte zones and deeper oxidised highlights.
• Always evaluate sample boards under the actual project lighting before committing to a full wall.
• For large feature walls, consider working in pairs — one lays on product, the other refines and blends.

Safety & environment

Klondike Corten is a water‑based, low‑VOC decorative system. It is suitable for residential, retail and hospitality interiors when used according to Valpaint guidance.

• Ensure good ventilation during application and drying.
• Wear gloves and eye protection; avoid prolonged skin or eye contact.
• Store sealed between +10 °C and +30 °C; protect from frost.
