BMA FINISHING AND PATINATION
BMA Finishing and Patination are terms that are often used but not always fully understood. BMA stands for Bronze Metal Antique and is an old name used to describe the traditional dark bronze colour that is typically found on historic archtiectural bronzework, such as doors, bronze fittings, window frames and facades. BMA finishing is also used in modern terms when a dark bronze colour is desired on a new copper alloy section. A proper BMA finish can only be applied to a copper alloy (such as bronze or brass) and cannot be applied to a steel (mild or stainless) or aluminium.
BMA finishing is a particularly useful type of patination: that is the intended colouring of a metal surface using a varierty of chemical solutions to form a colour change on the metal surface. Patination is not paint and whilst there are hundreds of chemical recipes to produce almost any colour possible, the vast majority are not particulary stable or suitable, especially for an exterior architectural surface. The reason that the BMA finish has been so popular for so long is that it is stable, provided that it is maintained.
We specialise in BMA finishing new shopfronts, features and fittings as well as the repatination of older existing bronzework where the patina has failed over time or has suffered damage.
Take a look at our gallery to see some of our first class BMA finishing.
