contact can do funny things when it gets hot. It has a High VOC content (>50%) which will remain trapped within the board and will contribute to issues of out gassing!
I agree with Gorgesailor. I'd avoid the contact in the future mate. Its just not worth the chance of ruining lots of hardwork!
Yeah , I'm also a bit sus on the contact cement, however I've used this method a few times and no problems . The only time I've had slight delam problems is when I used resin and cork . I'm presuming a dry join because the cork soaked up the resin . I get the idea of some fumes left over from the glue not being quite dry , but the volume of gas that ballooned the board would have to be more than some left over glue fumes . I wish I took a pic of the puffed up board .
But to be sure I might just use it on the rails , not for top and bottom pvc. And then let it sit in the sun before covering over .
First tinted layer of glass . 6 oz from mast track to middle of repair , 4 oz to front . Hopefully the red tint is a close match .
Then light sand of edges and another layer of 4 oz over the top , clear . The green grey tint ill use on the edge and around mast box should be a good match . I think the most obvious part will be the new and old deck join and the new and old sugar grip join .
As long as its solid .
Hi IMax, We used to use Contact to glue sheets of EVA on the decks of dinghies. Anyway it was fine for a while, after after a few months, it started to bubble or blister. There's lots of theories why, but the best I heard was where the contact was too thick it was going soft in the heat and resetting creating gas and blistering. But i doubt there would have been enough gas to cause the amount of gas you described.
Im hoping one will be enough . If it's going to chuck a spaz again , 10 sounds like a good number

How do you install the vent plugs Imax can you just drill a hole and epoxy them in, Im thinking of retro fitting one in my mistral because it has factory pin holes in between the screw holes in the Footstraps inserts for vents but they must let a certain amount of water in when on the water, thinking it would be better to seal them up and have a watertight vent, the board is 20kg so the last thing I need is water in it.

Pin holes between footstraps as vents sounds a bit strange, Are you sure ? It doesn't sound right .
The vent I use is in the mast track . I believe you can just buy a vent . I would just drill a hole and epoxy it in . Araldyte would work . Surfsail Australia sell them . U want the retro fit vent for $10.
depending on the year mistrals use goretex vents. I agree with imax pinholes near footstraps sounds very sus! and 20KG sounds way too heavy, could already be 10kg of water in there
If it's a Mistral OD , I believe there around 16kg . I'm not sure if that's with fin CB and straps . Add that together and you get 20 kg . Ill weigh mine .
Hang on .....
What board are we talking about .?
Deck filler sanded and edges color matched , ( i call it rot green ). It worked out pretty good .
Next , light sand , clear on rails and sugar coat .

I know its a strange way to vent a board, but there is no other vents anywhere on it and I have some unwanted footstrap inserts that I have removed from the board whilst doing deck work and the holes definitely go right through them so in theory that's where it would vent there's nowhere else on the board to do so. see photos sorry there taken a bit to close up but you can still see what I'm talking about. Its mistral prodigy 2002 and when i got it it had a sticker on the back stating 38lb weight. 18 years later after deck reinforcements and several repairs it weighs 18kg bare, add mast track/centreboard and rubber skirts/ fin and footstraps its about 20 ish kg, im almost certain it has no water logging.

Nice imax, almost back to it's old self
Thanks , fingers crossed it doesn't explode !

That's very strange . They would just suck in water when the board hits the cold water . Unless they are sealed off with resin , but then they won't vent . Looks to me to be a stupid idea . Unless i'm missing something ? Is it to let air out from when they squeeze in the plugs during assembly and then they seal them off ??? stab in the dark here ??
They wouldve been blank. But someone used incorrect length screws n went thru bottom of insert.

Its not the screw holes its in between them and there only 1mm holes
Could it be an anti rotation thing? some foot straps had a little peg to stop the strap twisting

Na there too small for that 1mm pin holes its got to be the venting system cause theres nothing else in the entire board

the holes are there to alow for the vacuum to pull the outer ski in in to the mounts as the boards are built in a vacuum mold and press

Hmm the holes are only in the top section of the inserts so that makes sense but how does the board vent then. do all boards need venting this one has a styrofoam blank like packaging you get with electrical appliances etc it does not absorb water and asa plastic skin. I guess I should just forget about it the boards nearly 20 years old and its never blown up or anything im sure mistral knew what they were doing when it was produced.
Not all boards have vents . I never undo mine . I don't let mine roast in the sun or take on planes . I do however have a black board that makes me nervous .

the foam they use and the build prosses no vent is required .i have 2 bic boards built that way 1 is over 27 years old still ok.
