Bird Brand black tar varnish is a low odour and quick drying formula that is most suitable for wood, metal, stone, tin and brick surfaces. The substance contains white spirit and can be applied over previously tarred surfaces. A five litre tin will cover approximately 50 metres square. After prolonged UV exposure, the gloss finish will turn into a lovely matt finish.
