Hello!

I purchased this used aniline leather chair in good condition.

I noticed a small spot on the back of the chair (where one might rest one's head) and decided to clean it with "Cavalier Leather Balm - conditions and renews fine leathers"....

Before I realized what I was doing - which was obviously incorrect - I had made a large round area that is distinctly lighter than the rest of the chair (please see picture).

The area I treated feels soft and supple while the rest of the chair feel waxy and slick.

It appears to me that I have lifted the protective coating that was applied to the chair.

I hope to be able to treat just this area and avoid treating the entire chair.

More pictures are available.

And of course suggestions are welcome!

FYI the leather balm I used is in the trash!

Thanks.

Dave

This look like a Pigmented Two-tone Effects leather (perhaps more close-up pictures to confirm the leather types).

Solution to the problem is to recreate the antiquing effect with matching color and pattern to match the original.

This need practice for color and effect satisfaction before attempting the actual repair.

If the color or effect does not match the surrounding area, you may have to strip the entire secondary color and re-antique the entire chair.


Product Information:

For:
Creating two-tone or an old English leather antique effect.

These pictures show that the Secondary Color has been rub-off.

Notice that the Darker Secondary Color is “Translucent”.

Picture #2 shows that they are different depth of shades, sort of a cloudy or molted effect.

These visual observations indicate that this is a pigmented two-tone effect leather.

As for a test of absorbency, almost all aniline leathers are absorbent.

A few drops of water can be dropped onto these surface and see if it is absorbed and turns dark.

Let us know you findings.

Drops of water on the damaged area turned the area dark and were absorbed.

But when the leather dried - the dark water spots were no longer visible and the area looked the same as before the water was applied...

Please let me know your thoughts.

Thanks

How about testing on unused area!

Does it still behaves as described?

Yes. Water drops on the area that I did not "clean" respond in the same manner as water drops on the area that I did "clean"...

Thanks.

One more inspection, we need to see the color of the reverse side of the leather.

Either from the seat cushion, unzip or from removing the staples from the dust cloth.

If possible take close-up pictures.

We are still determining if this is Aniline leather.

How do you know it is Aniline leather as you first mentioned?

The reason to determine the leather type is partly to maintain its original characteristic.

Aniline leather is more desirable and of a higher value than pigmented leathers.

Absorbency equals breatherability, as aniline leather is more comfortable to seat on for a longer period of time in hot season.

Preparation works is still the same; however there is a choice for this secondary color and the top coat.

For Aniline leather the secondary color of choice is anilineColor25™ and the matching topcoat is anilineTop79M™ (matte).

For Pigmented leather the secondary color choice is antiqueColor26™ with pigTop56M™ (matte).

Either color system to use, the color matching or determining the original effect still need practice and adjustment before actual application.

Thanks for taking the time to ask the right questions!

I thing the pictures should provide the information needed - if not let me know.

When I try to upload the pics at the web site I get an error message - so I am sending you the pics directly.

Thanks.

The above picture shows the reverse side (suede) attached swatch is Aniline Dyed.

And the smooth surface color looks more transparent with its satin to gloss sheen.

If this unused portion is absorbent we can confirmed that it is Aniline finished.

And the matching refinishing should be anilineDye27™ with either a gloss or satin topcoat.

So our refinishing choice is as follows:

1st Transparent anilineDye27™ with anilineTop79G &/or M.
2nd Translucent anilineColor25™ with anilineTop79G &/or M.
3rd Translucent antiqueColor26™ with pigTop5656G &/or M.

It is best to practice on the attached swatch for color, effect and sheen.

Step 1: Strip the secondary color residue free.
Step 2: Test color matching.
Step 3: Test matching effect.
Step 4: Test matching sheen.

What do you think?

Yes - the unused portion in the picture is absorbent.

I think we should proceed with the plan!

What would be my next step?
