Whiting Powder – 500g




Whiting Powder or Calcium Carbonate or even called chalk, is a component of leadlight sealant and is great to spread over the wet sealant after it has been applied to a leadlight to help it dry.

It is mildly abrasive so can also be used for cleaning stained and corroded surfaces.

If you buy our leadlight sealant kit, it includes a bag of whiting.
