Dekalb Aniline Waxy-Matte Leather Sofa – body oils, dull wears that need rejuvenating color and suppleness with a quality protection.

We shall use this Aniline (A.w) Waxy-Matte Leather Problem Solving Matrix as our guide to restore to “great shape”.

Phase-1 - Refinishing starts with removing of surface and penetrated body oil, grease and sweat.
Oil and grease will hamper or retard or resist any refinishing thus has to be removed.
Sweat has create more damages as it shift the amphoteric protein leather fibers ionic negative (-ve) which gradually denatures the leather as it repels the ionic negative (-ve) leather constituents like the tanning agents, dyestuff and fatliquor. Leather structure becomes tacky is a sign of leather denaturing a squeaky leather feel is a healthy leather and is pH balance in the degreasing process with Degreaser-2.2 > Acidifier-2.0. At pH value below its neutral pH value of 3 to 5 it charges the protein fibers ionic positive (+ve) to attracts all the other leather constituents – thus leather is create in this hydrogen-bonding process.

Phase-2 - Penetrated soiling that is suspended will need to be brought to the surface with the help of Hydrator-3.3 with the help of Eraser-4 to remove surface soiling during the wet process. Dwelling on the stain areas will help moves the soiling particulates to the surface.

Phase-3 - To have an even appearance, the existing topcoat is recommended to be “shaved” with Razor-60 during the hydrating process with the strength of the leather increases and the strength of the topcoat decreases – makes shaving an easier task with less surface grain damages. Need to be careful when removing the topcoat without causing abrasion that will turn the smooth skin into nubuck. However, worn areas may show signs of grain wear and deep damages may takes up an undesirable darkening effect when comes to repairs and refinishing. It may be difficult to match up without removing the existing finishes just like any other furnishing refinishing to start from an even appearance. As the finishing is clear the beauty and the blemishes will both show through as well.

Phase-4 - A “reverse-transfer” technique using Towel-5 helps to wick the soiling particulates through instead of still remaining on the leather porous surface. The stain towel is peel and any remaining residue on the leather surface is dry erased with Eraser-4

Phase-5 – Inspection to determine that stains if any are deal with according – see guide. Upon satisfaction the process is move on to rejuvenate its suppleness. Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system will both refresh the intensity of the color from within the leather structure redistributed to the surface and the leather gains its suppleness as the water contents evaporates. A 14% to 16% of ionic charged fat and oil remain in the leather structure returns the leather to its original cycle of useful life.

Phase-6 – Color would be refreshed with sufficient Hydrator-3.3 and Fatliquor-5.0 treatment and it will be further intensify and magnify when AnilineTop-21W is applied to appearance satisfaction drying between coatings.

The above process is my recommendation that will returns the leather appearance back to “great shape”.
