Our leadlight sealant kit contains a dry mix of powders and a wet mix of oils. When you are ready, you combine the two to make your leadlight sealant. You may have heard it called leadlight cement, though our version does not contain any Portland type cement at all.
This is the same mix that we use commercially and is well proven.
Also included is a pack of whiting powder to spread over the top of the freshly applied sealant and full instruction sheet.
