Lead Restorers

Description

Lead Sheet Cleaner:

Designed to remove all types of grime, bird fouling, airbourne pollution and dust from lead surfaces, either as part of a general clean-up or as a pre-treatment in preparation for surface restoration. Please note - Lead Sheet Cleaner will not remove patination oil, bitumen or oil.

Lead Sheet Restorer Formula G1:

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 the recently installed, up to as much as 50 years old.

Lead Sheet Restorer Formula G3:

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 restores for a period of time long enough to break down the adherent patina found on leadwork greater than 50 years old. It may also be used to restore an area of leadwork to match an adjacent new lead repair.
