How to colour artificial leather and plastic - For professionals

  • Vinyl and plastic parts should only be coloured with experience in colouring with spray guns and an equipped workshop (airbrush, extraction system, breathing protection etc.).
  • Changing the colour of leather surfaces is more work than refreshing the original colour. You need far more paint and time and a helping hand to colour in all folds.



  • De-assemble upholstery and covers as much as possible.
  • Remove any dust from the leather with a vacuum cleaner or with compressed air. Compressed air is better for the cleaning of folds and piping edges. Remove any remaining dust with a soft brush.
  • Clean visibly soiled surfaces with COLOURLOCK Cleaner for Artificial Leather. Remove dirt in the grain with the COLOURLOCK Leather Cleaning Brush.
  • Rub all surfaces with COLOURLOCK GLD Solvent. The surface will turn dull and sticky, which is important for the colour adhesion.
  • Smooth hard plastic, which doesn`t get sticky when cleaned with GLD-Solvent, have to be primed with Plastic Primer. This will generate the required adhesion. Only spray on a thin layer and start colouring before the stickiness is gone.



  1. Carefully smooth rough or cracking surfaces with the Leather Sanding Pad. Wipe off the dust using a moistened cloth.
  2. Stick together the edges of rips with COLOURLOCK Leather Glue. Fill cracks and rips with COLOURLOCK Leather Filler. Let the filler dry and repeat the procedure where necessary. Important: Extremely old, brittle and weak parts should be replaced entirely.



  1. Filter the COLOURLOCK Leather Colour before filling it into the spraying pistol and mix with 3% to 5% of COLOURLOCK Crosslinker DC and stir well! Use 3% Crosslinker on soft vinyl and 5% on hard plastics. Apply the colour at low pressure (approx. 2 bar/15-32 psi) evenly and not too thickly. Always apply several layers and dry with a heat gun before applying the next layer until the surface is evenly coloured. Apply the colour only as thinly as necessary: Thick layers of colour affect stability and grip of the colouration. Pull apart folds and piping edges and treat those first. Always wear breathing protection during spraying. Work only in a well-ventilated space.
  2. Mix filtered COLOURLOCK Top Coat with 3 % of COLOURLOCK Crosslinker CD. Stir well! Spray the mixture thinly over the dried colour and dry with a heat gun. Repeat if necessary. Mix only as much Top Coat with Crosslinker as you need in the following two hours. The Crosslinker is reactive and should not get in contact with water. Keep away from skin and eyes!
  3. Primer, Leather Colour and Top Coat can be dried with a heat gun and the steps should be performed successively to ensure that the fresh layers connect well.
  4. Smooth down rough areas with COLOURLOCK Polishing Pad 4000. Then, if necessary, again apply colour or only Top Coat.
  5. After 24 hours, rub a wet cloth on the colour to be sure that the surface has sufficiently been treated with Top Coat. In case of discolouration, the surface has to be treated with Top Coat again.
  6. Care the coloured surface with COLOURLOCK Leather Shield in order to protect it against wear and scratches.

Top Coat
COLOURLOCK Top Coat is a clear transparent product which seals the colour coat. It gives the leather's surface a protective seal against water and dirt, making it insensitive against general wear and tear. The Top Coat is available in a "Dull", "Gloss", "High Gloss" and "Vehicle, Furniture, Vinyl" versions. All versions can be mixed with each other. Professionals usually use the "Matt" and "Gloss" version and mix the two to get the desired level of gloss.Companies that don't work with these products on a regular basis tend to stock the 'ready-to-use' satin Top Coat "Vehicle, Furniture and Vinyl". The Top Coat "High Gloss" is for surfaces where the "Top Coat Gloss" does not provide satisfactory results. The Top Coat always has to be applied with Crosslinker IC2. The Crosslinker provides the necessary stability for the Top Coat. Only on very soft Aniline, where the grip of the leather should be preserved as well as possible, very little Top Coat without Crosslinker may be applied. Important: This product will need to be sprayed using a spray gun. It is suitable only for professionals who repair leather on a regular basis and have experience in spray work.Please consult us before buying this product if you have any doubts or questions.
