Topcoat treatment for black lambskin

[baglover]

By colour repairs, do you mean to sand smooth the damaged leather, apply leather paint, then apply topcoat and protector B?

What’s the difference between leather dye removal and prep7.7? I saw it on the website for dye removal, but the aniline matrix only has prep4.4?

Yes!

All three can be removed to some degree. Prep-4.4 has a pH value of 4.4 safer than Prep-7.7. LeatherDyeRemover-7.9 proves to be more effective for removing dyestuff. Ballpoint ink would need Prep-4.4 first to remove the grease then the dye component is removed by LeatherDyeRemover-7.9 > Acidifier-2.0 system.

What kind of leather paint is compatible with the topcoat? Can I use tarrago?

Test it out to your satisfaction on some leather scrap before your actual project.

I’ve tested the topcoat on a small leather bag. Some areas appear fuller than others. Should I buff the dull areas and apply again?

Not sure what you mean by "fuller"?

To topcoat shine with AnilineTop-76G, there is no need to buff-to-shine it.

What did you use for the application?

I use a facial foundation brush.

Sorry, it’s a typo: “duller”. Like some parts are dull even after applying additional coats of topcoat.

I used the foam brush provided.

Also, my attempt on the bag. I’m considering whether to use stripper and redo the topcoat so that it’s not so shiny. What are your thoughts?

I also realised that the chain may leave marks, so I’ll wrap them during hydrating. Also, I leave the bag inside a big plastic bag instead of cling wrap to avoid the cling wrap leaving marks on the leather when dry (no marks if still wet when fatliquor is applied). Any advice?

Remove all marks when still damp with Hydrator-3.3 before applying Fatliquor-5.0.

Stuff up the bag full with a towel so that it stays in shape and form during the processess.

It is messy to strip the topcoat as the entire process has to be repeated: Stripper-2.3 > Acidifier-2.0/Rinse-3.0 > Hydrator-3.3 > Fatliquor-5.0 >>> AnilineTop-76G > Protector-B/B+.

An option is to lightly sand with Sand2000 and used diluted AnilineTop-76G with distilled water to slowly build up your desire gloss level.
