Hi Gurus

need your kind expertise on this problem i am facing after moving in for close to 6 months to my new house. 

at least 6 spots of stains at different location of the kitchen have started to appear behind the glass in the kitchen. ID said supplier is surprised and this is the first time they encountered this. 

thanks in advance.. 

is it the glue which they used to stick the glass to the wall?

That's the glue at the back. but only 6months and the glue can be seen? Is it your tempered glass is too thin? otherwise the glue stain shouldn't appear so fast...

It is most likely the maxbond glue reacting over time with the spray paint which may have solvent in it.

It has nothing to do with the thickness of the tempered glass which is either 5 mm or 6 mm. 

Owners should consider art design glass backing which are much nicer and it seems the artist supplier has eliminated this problem.

Go and see his forum thread by Renotalk and there is a Renotalk article on him.  Here is my kitchen done by Kenso.
