ancillary lead products...
- Three products designed to improve, restore and enhance the appearance of lead sheet.
- Dirt and grime is removed by Lead Sheet Cleaner before lead surface restoration with:
Lead Sheet Restorer Formula G1 for recent leadwork ie. less than 50 years old.
Lead Sheet Restorer Formula G3 for old leadwork ie. over 50 years old.
Lead Sheet Cleaner has been designed to remove all types of grime, bird fouling, airborne pollution and dust from lead surfaces, either as part of a general clean-up or as a pre-treatment in preparation for surface restoration. Lead Sheet Cleaner will not remove Patination Oil, bitumen or tar.
Lead Sheet Restorer Formula G1 has been designed to remove oxide/carbonate patinas that form before the slower developing, but more adherent sulphite/sulphate based patinas. This will be on leadwork ranging from recently installed, up to as much as 50 years old.
Lead Sheet Restorer Formula G3 was designed for renovating leadwork during the restoration of old buildings and statuary. As it is in gel form, it will remain in contact with the surface to be restored for a period of time long enough to break down the adherent patina found on leadwork greater than 50 years of age. It may also be used to restore an area of leadwork to match an adjacent new lead repair.
ADVICE ON USE
- Before use, test on a small area to be cleaned.
- Protect surrounding materials and where possible, collect all washings and dispose of them safely.
- Remove any previously applied Patination Oil (contact Premium Roofing Products for advice on Patination Oil removal), clean and dry.
- Apply Lead Sheet Cleaner with a cloth or nylon scourer, wash down and dry.
- If further surface renovation is not required apply a coat of Patination Oil or Prepat.
- For further renovation employ either Lead Sheet Restorer G1 or G3 as applicable. Apply G1 with a cloth or nylon scourer or G3 with a staff paintbrush, wash down, dry and return to step 4 to ensure restorer is neutralised.
