Changing colour of aniline leather is a very different process from the straightforward restoration work which is a very simple process using aniline dyes in a carrying agent (not pigments or balms as these change the leather from an aniline into a pigment) making them very easy to apply evenly.
You cannot get enough depth of colour with the regular aniline dyes to actually change from one colour to another so you have to use pure aniline dyes. These cannot be applied by hand as they are too aggressive and would create patches on the leather as they cannot be spread - hence the need for spraying the product.
Anilijne restoration is covered on our course but we do not usually go into colour change of anilines as this is a specialist job and not one that most people would be prepared to tackle. We do cover this sort of work in our masterclass workshops that we do from time to time.
Our basic sourses are available every month and cover everything form cleaning to full restoration work, we are now taking bookings for May and June and beyond. Please contact us if you are interested.
Also our open workshop days are available free of charge on the first Tuesday of every month - come and see us to pick our brains, bring a problem or just find out what we do. Next one 7th April
