Bauld- Pigmeted Pink Sofa with Cat Scratch

We have a leather sofa that was dropped off that needs to be deep cleaned and the Cat Scratch to be repaired and dyed ASAP. I want to use pigment dye to help cover the cat scratch after we repair and fill it. Can you let us know the steps you do to repair this.

The standard procedure is taken from Kit-Sa7.cl, and should be adjusted according that matches the condition of your project. The “Cat Scratch” is a repair issue that needs to be addressed in conjunction with “Dry Prep” prior to Adhesion Coating. Besides the cracks have also weakens the leather structure and if there are not properly treated will affect the adhesion as the continuous deterioration or dry rotting will becomes poor anchoring for the finishing coatings and will fail sooner then expected. In the cat scratches we are actually concerting the suede surface into pigmented. There is also the different of treatment when it is clean and untouched, a Impregnator-26 > Bond-3D + Stucco-90 > Adhesor-73 may be ready to proceed with Micro-54 > MicroTop-54S > Protector-B/B+. In a contaminated and aged cat scratch especially with unknown cleaner may have denatured the leather, thus the leather pH chemistry integrity need to be address as well. Degreaser-2.2 > Acidifier-2.0 > Hydrator-3.3 degreasing system helps to degrease and pH balance at the same time. Leather rejuvenating system with Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 should return the leather to its original suppleness with 14% content of fat and oil to have a lasting durability to the leather structure to hold up the finishing system. Both ways a finishing system can fail, either it is the leather crust that fails of the finishing that fails. To ensure a long lasting refinishing repairs the leather crust integrity plays an important role and should not be skipped.

Leather Doctor® Kit Sa7.cl, micro-pigmented leather color refinishing kit is design for a holistic restoration approach to not only the finishes but also rejuvenating the leather for suppleness. Most of these repairs may range from missing finishes to abrading damages into the leather structure. Some expose areas may be contaminated with foreign soiling that includes conditioners, protectors, body oil, grease and sweat or alkaline overexposure from cleaners. A comprehensive repair for a long-term lasting solution will require a holistic approach to deal with both the exposed structure and surface finishes. The practical and functional softness and strength of the leather depends on the health of the structure with average thickness between 0.9 to 1.2mm from stiffness and cracking. The aesthetic aspect of the leather finishes averages 0.02mm (or 20 micron) in thickness for practical compressing and flexing from cracking. A leather-safe restoration system begins by stripping with Stripper-2.3 and rinsing with Rinse-3.0. Degreasing with Degreaser-2.2 follows with Acidifier-2.0. The suffix numbers of these four products denotes it pH value for recharging the protein fiber ionic positive besides the act of decontamination. The leather integrity is revitalizes once the ionic attraction between the positive protein fiber and its negative leather constituents like the tanning agent and fatliquor (fat, oil and water) is initiated. Leather rejuvenating system for softness and strength is accomplishes with Hydrator-3.3 follows with Fatliquor-5.0. Surface uneven absorption is seals with Adhesor-73 to reduce the need for color over-coating thus increase its flexibility and stretchability from premature cracking. Protector-B imparts a non-stick rub-resistant surface with a buttery feel, reduces noises that translate into less friction wear. As the leather surface is well lubricated it reduces compression when comes to heavy body contact thus reduces compressed creases and wrinkles.

Instruction:

Stripping Existing Deteriorating Finishes:
1. Cover and tape off frames, trims and protect flooring.
2. Mist sprays Stripper-2.3, Eraser-4 scrub with help of 2000-grit sandpaper feathering out seamlessly and towel extract for an even appearance.

Degreasing:
1. Shake Degreaser-2.2 to gel prior to use with a repeat shake and rest until it gels.
2. Transfer to Eraser-4; agitate to saturate the stain, feather out to the entire section.
3. Towel extracts suspended soiling after 10 to 30 minutes or before it dries until it shows clean.
4. Spray Acidifier-2.0, towel extract until it shows clean to a healthy squeak.

Hydrating:
1. Spray Hydrator-3.3 saturating the stain area and feather out for an even appearance.
2. Covering with tissue paper without airspace to trap wick up stains instead of remaining on the leather surface as it dries.
3. Peel tissue paper when crispy dry and use Eraser-4 to erase surface residue prior to fat and oil replenishing.

Fat and Oil Replenishing:
1. Spray Hydrator-3.3 to precondition the leather prior to fat and oil replenishing.
2. Spray Fatliquor-5.0 and redistribute with foam brush until saturation.
3. Repeat application each time water contents evaporate until fully saturated.
4. Drive remaining surface remnants free of milky fat and oil until it turns clear with Hydrator-3.3.
5. Allow natural drying for extra softness.

Dry Prep:
1. Erase wick-up residue with Eraser-4 prior to repairs.

Cat Scratch Repairs:
Impregnator-26 > Bond-3D + Stucco-90 + Adhesor-73

Adhesion Promotion Coating:
1. Apply Adhesor-73 by foam brush to seal surface uneven absorption rate and promote adhesion simultaneously.

Color Coating:
1. Apply color matching Micro-54 + 10% Thickener-48 for flow control and airbrushing for professional result.
2. Fine dry atomize dispersion with more air is achieve with 80 to 100psi of air pressure.
3. Light spray is preferred and let dry in between coats to build up colorcoat.

Top Coating:
1. Shake the product well and apply by airbrushing for professional result.
2. Use lint free paper towel to even out drips and streaks.
3. Speed dries between coats with help of hair dryer.
4. 2000-grit sanding may applies to improve touch and appearance.

Rub-Resistant Protection:
1. Mist sprays Protector-B redistribute with a foam brush / paper towel and ready for use when dry.

>>> Hello Roger, I received the leather dye today for Bauld and it is pretty far off from the color we need. I attached a picture so that you can see the difference. This was a rush job so I do not have time to wait for more dye. I also know that Chet requested pigment and not Micro. We will try to do what we can to make it work. Can you tell us what we need to add to take this from a tan to the salmon pink color it actually needs to be because the tan dye you sent will not work for this client at all.
Thank you,

You will need to add up to 10% of Thickener-48 to stabilized the mix otherwise the white component which is a heavier pigment will settle to the bottom of the application. The Thickener-48 will keep the color mix in suspension until it dries to reflect the the desired intend color.

You should get it right unlike this picture you show!

Shake up the custom color mix, then add 10% by weight to it and shake again very well before you apply.

Please show if you can get it right?

Note:
Pigment-64 is already an obsolete product for a long while - have explained that to Chet for the reason - check with him and should be deleted from your order form accordingly.

>>> The dot you see on the left is mine from matching using your base with no thickener. I used 535ml of your Bauld mix, 160 ml of white and 15 ML red to achieve that smooth salmon.

The dot next to it is your mixture with no thickener, next to that has 5% and then dot above has 10%. Even when Thickener pulled the pink and brown more together it was still a brownish pink not a salmon.

I get where you were going with the thickener to pull the dyes together and stop the from separating (as shown on the towel with pink in the middle and a brown halo. But even with it being pulled together It was not light enough. But at this point with my added colors I am very happy with where the dye color is now and the texture.

Thank you,

I understand and you have done it right.

Tips-1:

A concentrate of Aniline-76 clear may help to stabilize such a situation where the mix of different specific gravity is at the extreme end - heavier sinks and lighter floats - thus the separation. Final test should be done on the leather itself not on absorbent paper - it shows the lighter weight pigments moves faster and heavier pigment just stick together and does not move to give the halo effect - it will be less obvious on a non-absorbent surface as posted by Nichole #3. Let see on the same surface how it looks like.

Thickener-48 up to 10% helps.

What you have done also helps.

Color matching ultimately may still need fine tuning at your end (a larger surface then from a little square sample), thus a collection of some standard colors do comes handy.


Tips-2:

Make sure you do not under-estimate the quantity you need when you order a custom color - even with a given formula - it is universally accepted to have a 5 - 10% variance from subsequent mix - the lighter color the more the variance will be.

Color matching sometimes just like this case takes the whole day (and time costly) to get it right - that is why it take longer then usual and Chet is not too happy.
