I have a client who installed 20 000sqft of sand blasted
granite in his lobby.
It has been sealed with a silicone
impregnator.
It has held up beautifully for the last year
The cleaning company came in and started to clean it using
a black pad to remove marks that were left behind from the winter
carpets
What has happened is that the black pad as acted as an
abrasive and sort of polished the fresh , bright sand blasted finish,
leaving what looks like a darker spot
Personally I think that trying to keep it looking so light
will be an impossible task unless I find a way to mimic the sand blasted
technique indoors.
I will accept any advice, as I am going for tests in
tomorrow
I have acids
Degreasers
White pads
Blue pads
One of those rotating washer blasters
What do you guys think?
