Leather dye doesn't adhere – causes of poor adhesion and proper preparation
If leather dye adheres poorly after application, behaves unevenly, or rubs off prematurely, the cause is often not solely due to the dye itself. Crucial factors include the substrate, cleaning, degreasing, preparation, and a thin, controlled application of the dye.
The most common causes
- Grease or care product residue on the leather
- silicone or unsuitable previous care products
- insufficiently prepared, highly glossy surface
- Too thick a coat of paint
- unstable or already detached old lining
- unsuitable type of leather or unsuitable substrate
Why degreasing is so important
Skin oils, care products, and other residues can prevent the new coating from bonding reliably to the substrate. Steering wheels, seat bolsters, and armrests, in particular, must therefore be thoroughly cleaned and properly degreased.
Check old surface
A new coat of paint can only be as stable as the substrate beneath it. If the existing finish is already peeling, loose and unstable areas must be professionally prepared before repainting. Simply painting over them will only mask the problem.
Thin layers instead of one thick layer of paint
Leather must remain flexible. Therefore, leather dye is applied in several thin layers. Each layer should be applied evenly and allowed to dry completely before the next is applied. Applying too much dye can impair the appearance, feel, and durability of the leather.
Protection after dyeing
After the paint has been applied, a suitable surface protection is an essential part of the process for any appropriate repair system. This enhances resistance to abrasion and daily wear and tear.
When not to just dye your hair a new color?
For open-pored aniline leather, suede, highly brittle material, or unknown coatings, it should first be checked whether the chosen method is even suitable. A standard re-dyeing process for pigmented smooth leather cannot be applied to every type of leather.
Frequently Asked Questions
Can I simply dye over old leather dye?
Only if the existing surface is stable, clean, and properly prepared. Loose coatings must be treated first.
Why does paint rub off particularly quickly on the seat bolster?
Seat bolsters are subjected to considerable mechanical stress when getting in and out of the vehicle. Preparation, a thin application, and surface protection are therefore particularly important.
