Pigmented (Simulated Leathers or Faux Leather) - Sticky Surface!

Hi everyone

Hopefully my question falls within the remit of this forum and would appreciate any suggestions.

I have struggled for a couple of years to find some dining chairs that match my cream leather sofa, with no success.

So desperate measure were required so I purchased 4 x chairs that are cream but a much lighter and frankly look out of place. By the way the material for these chairs is described as Faux Leather hence my initial question about the suitability of this forum.

My master plan was to buy an special aerosol spray from a company who say their paint is especially made to bond with Faux Leather. I duly found a perfect match, colour wise, and proceeded to spray one chair by way of an experiment. The good news was it went on OK and the colour is perfect. The bad news is that some two weeks later the surface is still tacky to the touch. Its not wet and the paint doesn’t come away on your hands or clothing but place the flat of your hand on the surface and take it off and its like peeling off a Band Aid. Maybe not quite that bad but if you sit back in the chair with say a woollen jumper on, then fibres stick to the surface.

So getting desperate and have three chairs in limbo. Anyone any ideas how I can harden up the surface ?

Oh in case someone suggests. I have tried contacting the suppliers but had no response

Regards

By creating a tougher film that also ties up some of the hydrophilic elements that eliminate stickiness.

Topcoat determines the luster level and seals the colorcoat at the same time from this link: http://www.leatherdoctor.com/servlet...-64/Categories

Topcoat – PigTop-64
Clear topcoat is design to seals the pigment basecoat and decides its desired luster that range from matte, satin to gloss. Gloss is the strongest of the three and may be used as the initial coating prior adjusting the luster to satin or matte. These topcoats are intermixable to match the original luster. Pigment coloring alone without a sealing topcoat would be: a) poor in aesthetics; b) susceptible to tactile sensation such as tackiness; c) poor physical properties such as wet rub, sweat resistant and scuff resistant; d) poor in ageing properties such as soil resistant and wet cleaning resistant.

Leather Doctor PigTop-64

For the finer micro -pigmented also known as semi-aniline leathers, use MicroTop-54 instead. These lusters are intermixable to produce the in-betweens to match. These are waterbased soft polyurethane topcoats that are lightfast and non-yellowing. They have excellent flow and leveling properties, recoatable and form a flexible tough film.
