Osmosis dryout

I had a thought on possibly speeding up osmosis dryout and wondered if anyone had ever tried it. What about throwing in generous quantities of industrial dessicant and then making an airtight seal with plastic or visqueen around the water-logged spots? I''m in Hong Kong where the humidity in the air is 80-90% nearly year round. It gets a bit better between Oct. and Jan, which is when I plan a dryout, but still will be around 70%. Any ideas on how to ensure the dryout takes place would be appreciated.

Regards,

Osmosis dryout

Scott,

My major blister experience is now closing in on 15 years. Having gone through it, I continue to have a morbid curiosity and keep abreast of current trends. Having been in HK, I can understand your predicament with relative humidity.

Up until recently, heat applied externally and internally was the major accelerating tool for blister dry out. Now, visqueen tarps and vacuum pumps are gaining favor. Your dessicant concept may add a favorable twist to the concept.

The vacuum concept performs well above freezing and in all ranges of RH. Surprisingly, the pump requirements are modest - 3 to 6 psi.

As you prepare for this project, be ready to mark the blisters with a crayon or chalk as quickly as possible after the boat is pulled and pressure washed. Even 24 hours later, some will subside to the point of invisibility.

Here''s hoping you are dealing with gelcoat blisters, only!!!
