wow, they were JUST talking about that on the forums and I JUST posted there..
Pocket lifting on CND products is/was directly related to too wet of
an application.

I've had some serious thought as to the causes of "pocket lifting"
can you confirm or correct this theory? The thumbs are larger, they
get banged around more often, product does do a bit of shrinking as
it cures and if the ratio is even slightly too wet in this large area
of the thumb nail plate it will "pucker" is the best word that comes
to mind right now.. and cause the pocket or lift dead center with the
rest of the product attached like cement Now she bangs that baby, I
bet it doesn't have to be even a bang she'll take notice of.. and
eeeee eeee eeee there goes that pocket.. slightly larger now.. she
bangs it again and it spreads again.. How does this theory hold up in
the chemical world of nails? Debbie webmaster beautytech.com
Wow! Someone sure knows their product chemistry. This explanation is
right on the money. Excess liquid=excess shrinkage. The more liquid
you use, the greater the product will shrink. Also, the more curved
the nail plate, the greater will be the effect of shrinkage. Just
like a magnifying glass focuses light, a curved nail plate will focus
the forces of shrinkage. These forces will be focused to the apex
(highest point on the nail) and in the center of the plate. So that
is where the product will pop free if these forces become excessive.
I also I agree with the thumb issue. The more product you use (more
on the large fingers and thumb) the more the shrinkage. Therefore,
the most likely nails to form center pocket lifting are; large nails
with great curvature and the product is applied too wet.
Once the pocket forms, if the lifting opens it to the outside world,
then bacteria can get into the space. An open pocket can breed common
bacteria and cause "greenies". It all makes sense if you think about it.

Hi Techs!
Can someone tell me what causes air pockets? I mean big air
pockets. Are some acrylics more prone to air pockets than others?
Thanks!
