Porcelain pavers appear to be losing their colour

longwalks1

weve just had a porcelain patio laid, approx 60m2, it was lad 4 weeks ago.  Been out today to give it a spray over with the garden hose and a sweep and noticed around a lot of the pavers, it looks as though the top colour/coating (I know that arent painted or coated but the only way to describe it) is wearing off or coming away?  There no evidence of a residue but its on most of the pavers, even the few that havent been grouted yet.  At first i thought it may of been grout residue but its not.  

Any ideas please before I call the supplier?   Just wondered if anyone had ever seen it before?

Thats not the top colour/coating coming off: that's the top layer of your slab, exposing the substrate, Very bad, it should never happen. Complain to the supplier for sure.

Are they branded slabs ?

Hi chickereeeee - I googled substrate but it said it was the base that tiles/pavers and stuck to? Or do you mean it’s the main part of the paver itself, prior to the top coat being finished?

ive looked at one paver in the showroom where I bought them and that looks the same?

Hi molerat - I’ll check tomorrow as have a couple left unused outside. I think they are from Italy, which I read previously that is a better place for porcelain pavers to come from?
