Check material and color
Assume pigmented smooth leather and test the black tone and gloss level on a hidden area.
Clean and dry
Remove dirt and cleaning product residue. Allow the surface to dry completely.
Degreasing and preparing
Carefully remove grease, silicone and care product residues, and gently smooth only loose or hard edges.
Only fill true depressions
Apply liquid leather sparingly in thin layers. Do not apply it over large areas of intact leather.
Dry and smooth
Allow each layer to dry sufficiently and only reapply a thin layer if necessary.
Apply leather dye thinly
Apply several very thin layers of paint and allow the transitions to blend out in a controlled manner.
Seal and allow to harden
After complete drying, apply the sealant thinly and only put normal stress on the surface again after sufficient drying.
