Introduction

Understanding Fire Damage

When surfaces are exposed to fire, the residual soot and char can continue to affect appearance and air quality. Burned areas might look permanently discoloured, and the smell can linger long after the flames are gone.

Why Conventional Paints Fail

Fire damage often involves soot, char, and deeply embedded odours. Typical paints can’t fully lock down these contaminants, allowing visible spots or smells to bleed through.

SPO Shellac Stain & Odour Blocker: The Go‑To Solution

SPO Shellac’s heavy‑duty, shellac‑based formula effectively caps off stains and seals in smoky odours. Once applied, it creates a stable surface that won’t allow charred areas to bleed into subsequent paint layers.

How to Cover Fire Damage

Preparation

  • Remove loose soot or debris with a damp cloth
  • Let surfaces dry completely
  • Lightly sand glossy or rough patches to help the primer adhere

Application

  • Stir the primer thoroughly
  • Apply a thin, even coat using a brush or short pile roller
  • This paint dries extremely quickly, so work fast. Avoid leaving the tin or brushes exposed to prevent them from drying out
  • Methylated spirits will be needed to clean any tools used

Finish

  • Check for any remaining discolouration or odour
  • Once fully dry, follow up with your chosen topcoat
  • Ensure good ventilation—SPO Shellac is flammable
