Patination Oil

Patination Oil is a white spirit based surface treatment that prevents Lead carbonate from forming on the surface of Lead Sheet and ultimately helps prevent staining to adjacent materials.
Patination Oil
When newly fitted Lead is exposed to rain or moisture it builds up a natural patina in the form of a soluble Lead carbonate. Future exposure to rain can wash the carbonate on to adjacent materials causing staining or discolouration of surrounding building materials.
Patination Oil should be used on Lead roofing, flashings and cladding to give a uniform, attractive appearance where the Lead is visible. It is also necessary when water flowing from the Lead Sheet surface may come into contact with other visible building materials.
  • Prevents the white carbonate that forms on newly fitted Lead from staining adjacent materials
  • Provides a uniform, attractive appearance to new Leadwork
  • Easy to apply
  • Apply with a clean soft cloth immediately after fixing and before the Lead gets wet
  • Work horizontally or vertically in straight lines
  • The leading edge and underside of the sheet should be coated to a depth of 75mm
  • Patination Oil should be applied with care when the Lead is near UPVC and bitumen
  • Apply in a well-ventilated area, away from naked flames
  • Suitable gloves should be worn
Packaging and Coverage
  • Available in 1.0 litre and 0.5 litre cans
  • One litre covers approximately 60 square metres

Patination Oil ‘How To’ Video Transcription

Below is a transcription of a video shot by BLM with Tim Fuge, Young Leadworker of the Year 2016, on the correct way to apply Patination Oil onto Lead Flashings.
Tim Fuge:
Hi, my name is Tim Fuge and we're here at the LSTA Training Centre in Kent to bring you the latest BLM guide to using Patination Oil.

Why Use Patination Oil on Lead Sheet

Tim Fuge:
When newly fitted Lead is exposed to moisture, it builds up a natural patina in the form of a soluble white lead carbonate. Future exposure to rain will wash the carbonate onto adjacent materials causing unsightly staining or discoloration. Patination Oil is white spirit based surface treatment that prevents white carbonate from forming on the surface of newly fitted Lead Sheet and reduces the risk of staining to adjacent materials.

Tim Fuge:
It should be applied to lead roofing, cladding and flashings to give a uniform attractive appearance where the Lead Sheet is visible. It is also necessary when water flowing from the lead sheet surface may come into contact with other visible building materials. Ensure the Lead is clean, dry and free from cement dust and loose debris that might affect adhesion. Shake the can vigorously for two minutes prior to opening. Apply with a clean soft cloth to all visible surfaces, leading edges, both surfaces in lap joints, the underside of flashings to a depth of 75 mm and Lead clips. Working horizontally or vertically in straight lines.

When to apply Patination Oil to Lead Sheet

Tim Fuge:
Patination Oil should be applied as soon as possible before the Lead is allowed to get wet and by the end of each working day at the latest. Where foot traffic may occur during the fitting of Lead Sheet, a second coat should be applied on completion of the project when all surrounding work is finished. BLM Patination Oil is available in half litre and one litre cans. One litre should provide approximately 60 square meters of coverage.
