Spraying leather seats to re-color or restore them requires careful preparation and the right techniques to achieve a professional finish. Here's a step-by-step guide:
1. Preparation is Key
-
Clean the leather: Thoroughly remove any dirt, grime, or previous treatments. Use a dedicated leather cleaner for this purpose.
-
Prepare the surface: Use a leather prep product along with an abrasive pad (like a Scotch-Brite pad) to gently remove the existing finish. This step is crucial for the new colorant to properly adhere. Be careful not to damage the leather.
2. Deep Cleaning
- Alcohol Cleaning: After prepping, use an alcohol cleaner to remove any remaining residue and degrease the surface. Wipe down the leather with a clean cloth soaked in the alcohol cleaner.
3. Repairing Damage
- Filling Cracks (if needed): For seats with cracks or significant damage, use a leather filler like Flexifil to fill in any imperfections. Allow the filler to dry completely and then sand it smooth.
4. Applying the Colorant
-
First Layer (Sponge): Apply the first layer of leather colorant using a sponge. This helps to create a base layer and ensures even coverage, especially in areas with texture or crevices.
-
Spraying Colorant: This is the core of the process.
- Choose the Right Equipment: Use an airbrush or spray gun designed for leather finishing. Aerosol cans are an alternative but offer less control.
- Mixing Colorant: Ensure the colorant is properly mixed according to the manufacturer's instructions. You might need to thin it with a suitable reducer.
- Spraying Technique:
- Distance: Hold the spray gun approximately 6-8 inches away from the leather surface.
- Overlapping: Use smooth, even strokes, overlapping each pass by about 50% to prevent streaks.
- Multiple Coats: Apply several thin coats rather than one thick coat. Allow each coat to dry completely before applying the next. This prevents runs and ensures proper adhesion.
- Drying Time: Refer to the colorant manufacturer's instructions for recommended drying times between coats and after the final coat.
5. Applying the Finish
- Spraying the Finish: Apply a leather finish or topcoat to protect the colorant and provide the desired sheen (matte, satin, or gloss). Use the same spraying technique as with the colorant – thin, even coats. This step also provides protection against wear and tear.
6. Final Steps
- Drying: Allow the finish to dry completely, usually for 24-48 hours, before using the seats.
- Conditioning (Optional): After the finish has fully cured, you can apply a leather conditioner to keep the leather supple and prevent cracking.
Important Considerations:
- Ventilation: Always work in a well-ventilated area when spraying leather.
- Masking: Mask off any areas you don't want to be sprayed.
- Testing: Always test the colorant and finish on an inconspicuous area of the leather first to ensure compatibility and desired results.
- Safety: Wear appropriate safety gear, including a respirator, gloves, and eye protection.
