Science Question re Pocket Lifting

[Cathie!]

Bit of a technical question....

If you were working your product slightly wet (I don't mean ringing wet), how long would it take before pocket lifting got to the extent that you could see it with the eye?

Would it be before the product had finished curing or would it worsen over a series of days or weeks or months?

Thanks in advance.

I have pocket lifting on one of my nails and it didnt show immediately but that evening it turned into dull patch then come the next evening you could see it properly. As it dries the product shrinks so is more noticeable.

Thanks Lucia, so you would say before the product has finished curing?

Just looked again and it is worse now than before it ahs spread.

i first noticed as it was polymising (l&P not gel) and then as it really set it was more noticeable so first within 12hrs thhen definately within 36hrs.

Hi,

L&P systems all shrink when they are created normal shrinkage is between 7-11%...over 12% is excessive. (different for uv gels)
Excessive shrinkage causes many problems, lifting, tip cracking etc.......
Pocket lifting is lifting at the center or apex of the nail caused by working with too wet a mix ratio causing excessive shrinkage....with clients actually feeling the enhancement tightening or throbbing.....this usually occurs within a few hours of applying but depends on how much the product shrinks.

If you are getting pocket lifting after a few days it could be that there have been air bubbles in the enhancement again caused by too wet a mix ratio......and these have enlarged as the product hardened.

I have seen a presentation where Doug Schoon showed pocket lifting occurring...the film was speeded up and it was fascinating....you watch and wait for it to POP off the nail!!!....certainly makes you check your mix ratio!

how do you remember all this?
or do you have a handy little book near the pc hun

i know one thing i wish I could explain things the way you do, it always makes sense without being too OTT in jargon.

thanks hun

Excessive shrinkage is my pet hate!! (amongst others!).......Students at first always work too wet, just because they can!....they learn quickly not to work with a dry bead because it fights back!!....but too wet they all do ! despite me pacing up and down the room rhyming off the many problems they can encounter......
Must admit I had a sneaky peak at Dougs book for the shrinkage percentages though!!!
He is a jargon free zone too, so easy to read for a science book.

Thanks for those answers guys...
