Default Ping: All You So-Called Osmosis Experts!

Okay that is a layman's undertaning but you got the main idea.


Fact: A blistered bottom is the result of untold hours of this pressure
gradient. Sometimes it takes years of submersion which creates the pressure
gradient for blisters to occur. Osmosis is a


relatively slow process when


this is not a fact these are abstract equiviacal words. In other words
this is an opinion not a fact.

pressure differentials on either side of a membrane are not great.






Fact: Spraying the blistered bottom repeatedly with fresh water does NOT
create osmosis as there is no pressure gradient.



That is absolutly true. All here will agree including Skip, Buce, and
myself.



Fact: No pressure gradient = no osmosis


This is true also. NBow lets see if you udnerstand what happens when
you take a boat out of the water


= surface wetness only = no
penetration into soggy laminate.



Fact: No penetration = wishful thinking and NO effect upon reducing the
moisture in the soggy laminate that combines with layup chemicals.


Here you start to miss the boat. In other words you have a significant
fact chunk missing.


Now, to the crux of the matter which is


.................. how to remove the moisture from the
laminate before coating the bottom with an impermeable 'barrier coat.'



Yes this is a very imprortant step in the process.



There is only one way to accomplish this drying process and that is not by
osmosis but by diffusion through the membrane and evaporation of the
moisture at the surface of the membrane.


Okay and where does this "moisture' go? Oh. by the way it is not water
ie moisture. it is a chemical.


This process involves storing the
soggy layup in a low-humidity environment for a year or two so diffusion and
evaporation can occur


Yes, but you need to do something several times a day for the first
week on the hard. And prey tell what is that my uninformed?



and the hull can be tested with a moisture meter until
it reaches acceptable levels.



the hull will not "dry" if all you do is stand and watch it.


I welcome any rational, enlightened explanation of how spraying the hull
with water can possibly negate or supersede the above facts.



God Damn,,, you are a ****ing idiot Willbur
