Hi, (again)

What it is and what I did
-Hurley 700, 1974
-some osmosis
-I did remove the gelcoat with sand paper, corrol 40
-many times the hull was washed with clean, hot wather

Deformation at dry setting
-not at all
-hull is fine, not grinds or what ever

Moisture measuring
-the work, sanding, was done in medio December
-the weather in Januar and Februar was bad, mosthley under 0 and a lot of rain
-several times I did read the moisture with an Skipper
-on stand 1, outsite hull, always green and yellow, it also looks it is drying
-on stand 2, insite hull, mosthley red, the hull is still wed

Ph
-after reading this site I tried to find out it the type of osmoses
-first I made 5 conical holes in the hull, no fluid seeps out, also not after heating
-after sanding some parts a very fiew fluid came out
-measuring seferal of times gives Ph=4

Choice
-it looks like my boat has an osmosis type 1 or starting 2 (because the boat is too wed)
-the boat might stay on the land for an other 1 or 2 months
-but I have the feeling, the boat will not be dry after that time
-after reading the earlier anwere on my message, I think
it is right to not use epoxy
-so I think about an other material
-it is Primocon (International), 1 component, a primer of hight quality,
used with succes in this kind of situations, wed hulls
binding: polyvinyl chloride copylymeer
pigment: aluminium, anorganic stuff

So I follow your advice, so I do not apply a very barrier coat. And I can inspect the hull regular.
and I might sail after 1 month

Please give your reaction

Greetings Loek
