Hello,
the leather of your club chair is really very dry. It is quite possible to renovate it of course, but the first thing to do is to rehydrate it well with one or more applications of "Pied de boeuf" nourishing oil.
You will then need to obtain our leather tear repair kit and follow the instructions.
Once the repair is done, you must recolour your leather. The characteristic feature of club armchairs and sofas is this colour patina. The colouring is not homogeneous, it is nuanced. To regain this effect, you will first have to apply our pigment recolouring agent which will give a uniform colour (250ml for a complete chair).
It is then the dye (in aerosol form) that you will project on it for a longer or shorter period of time everywhere, which will make it possible to give back this Havana shade.
Finally, you will need to apply protective wax (in a can) or patina wax (in an aerosol) to protect your leather, and give it a "candle" feel.
For recolouring, we offer a complete kit here, which will save you the cost of buying products by the unit and at the same time save you money.
