black/white foil

[nizzle]

Hey i didnt know where to put this. but i put it here since its a bit weird question i think.

half year ago, i buy the black/white lightproof foil. for darken my room. there it was very very white. then i took some of that use it for the floor in my room. then i take this new foil and going to put it on the wall and i notice a color difference. the new foil is more light grey than white...

im just scraching my head now, because its same foil from same place.

is there anyone that would know if this is a factory mistake,
i dont want to put it in my room if it dont give me those 85% reflection, its look weird, more like it looks wrong. hope someone understand why this qestion im building new room cheap room, and i just want it to be good from start with good materials, and not fail materials.
hope i get an "Intelligent" answer for this..

if it is the exact same brand, then it is probably because one of them sat in direct sunlight and it discolored it.

that happened to me before.. i had two side by side, but one was in the light cause of a crack in my garage that let light through

85% is nothing special. Flat white wall paint will do better than that.

heey the dungeoun how did it miscolor. ? did it get more white. or more grey ?
because the very white i got, have been in direct sunlight.. the grey i just bought ..
but if it only was light from a crack how could the whole piece get discolor ?
just sound weird that it get more white if exposed to sunlight alot.. would make more sense to me if it got grey by being in the sun alot...
hope you got answer for that

freezer this is only tempoary, i think 85% is good hehe.

ROFL. i just put a 22w light close to the white side. and what do i see. small little dots everywhere , where the light get threw the foil :S NOT very lightproff.
first i buy from bg-support. and the foil i get is pure crap. there came daylight into my room. . and now i buy this from a shop where i live and then its the same, just different way !!!!!!!!
Why is it growshop's have to sell this crap to people?. 2 times in 1 week rofl. i sure am pissed now. and ofc the foil is grey when theere can come light on the other side of it because then its the black that comes threw the white and make it grey, if that makes sense.. !

bg-support. said. we dont believe that its our foil. LOL?. so no new from them or money back..
