Patina Gel turns liquid patinas into a gel patina to allow for easier application on vertical surfaces. To mix, add the gel by weight or volume up to a 1:1 ratio into any liquid patina. The mixed gel patina may be slightly lighter in colour compared to the original patina, as it acts as a diluting agent. When used in conjunction with concentrated patinas, the patina gel acts as the diluent. This would apply to the Birchwood range; PC-9, M38 Antique Brown, M20 & M24 Antique Black, and A14 Aluma Black.
