I have asked my car dealer to give Scotchgard coating on my car seats
and floor mats. While the shop was coating my car interior with
ScotchGard, I was watching them so that they cannot skip any part.
They did it well. Then I dropped drops of water, and water just soaked
in. The dealer could not explain it. I have got a call from dealer
another day explaining that liquid (milk, coffee, and...) can get into
the fabric BUT it can be "blotted out" easily using a paper towel.
That's the advantage of using Scotchgard. I am suprised because I
think scotchgard never lets any liquid gets into the fabric at the
Schtguard just blocks the fabric, it does not make it a single coat of
material like a sheet of plastic... its the threads in the material
thats blocked, so the liquid does not go into the thread and just goes
past it like you said.. so the seat does not rots or the roachs dont eat
it up trying to get to the sugar in the liquid that will settle into the
fabric.... so the dealer is right and the expectation of scotts guard
making the seats somthing that they are not is a problem that alot of
people have with it... and if you paid $500 for it on a new car, they
they took you to the cleaners... the cost of this should be like $15 for
a can of the stuff at the grocery store and you do it yourself....
As the others have said. It does not make anything waterproof. On some
fabrics it will make the water bead up, but even then it can get into the
fabric. If you want total waterproof, put plastic covers on it, but that is
sure to be very uncomfortable.
Scotch guard and similar products waterproof/seal the yarn, but does not seal
the spaces between the yarn in loose woven cloth. This means that stains cannot
penetrate the yarn and set. If the treated fabric is a very tight weave, than
yes, water will bead up and run off. On a loose weave, it just prevents stains
from soaking into the threads. It is not usually a completely waterproof
When we bought new dining room furniture, the salesman tried to sell us
Scotchguard for $10 more per chair. The chairs came with plain, black
cotton fabric and I had already told him I would recover the seats.
Don't like black and we had a cat at the time, so his hair would have
been a problem. Sales guy just wouldn't let up - I think Scotchguard is
a placebo, but that's just me :o)
My recollection is that Scocthguard was deemed to be toxic and 3M
decided under pressure to remove it from the market several years ago.
Is it possible that today the product sold under the name "Scotchguard"
is a less effective material?
As I recall it was removed from the DIY market, but still available for
professional application. The name when on some other products however. I
don't think I have seen any of those products for some time.
