Hiya,
I recently bought a cheapish second hand board that I knew was heavy (it's a little project board...) and am waiting for some much hotter sunnier days to try to wick the water out, being the go-to culprit (especially when I discovered one, maybe two of the footstrap insert holes were able to be poked through to the foam with a toothpick (why don't they just make the inserts a few mm longer rather than having them so close...). A clear tell was deeply squashed EVA foam around those holes....
I have had it in the car (vent plug out) once or twice and there's not even any moisture on the wick at all. I made a wee low-pressure vaccuum pump from an aquarium air pump (see pics) but that's not doing anything either (probably needs heat too...) after a night of running.
It's a 105L JP Freefoil board, stated weight 7.6kg, actual 8.8kg (albeit with 3 footstraps) vs my 115L version of the same board stated 8.1 actual 8.3 (4 footstraps and slightly wet too), so it's a heavier than it should be and heavier than the bigger version. The 105L has had a couple of repairs apparently.
Anyway, while I wait for sun, I thought I'd ask how much an extra coat of spray paint might have added to the weight as the guy hadalso sprayed it a (bloody awful) orange colour on 2/3rds of the bottom and the sides and ends. The top is mostly EVA foam.
ta!
That board is so fragile if it's the LXT that I almost wouldn't bother
now after that rant - it's very hard to get any decent amount of water out if it has time to travel. U will only suck it out at the point of ingress for a brief period. Let's say a week. but it is been on end gravity will move it. If it's benergy walked on in use, the up n downy motion will pump it thru the board. If the water came in the top it will want to sink to the bottom in use.
you then need a big hole, gravity, warmth and air flow. It can take a month plus in summer to get half that out
as an aside though, it you know the inserts leak then why crack the vent open? It's not going to blow up as it can vent out the holes, which is what u want to get some water movement
Back to weight
paint - stuff all
big rattle can job, 200g max it's almost all solvent

Hi Mark,
It's the LXT and yeah I know, I have already repaired some dings on my wife's 115L version, it's like eggshells.
But anyway, I'm going to give it a go, see what I can get out of it water wise. No idea about the history, so I'm going to have to suck it and see (excuse the pun), just keep applying the four elements you mentioned and be patient, appreciate the expertise as always. If there's a fifth element I'll need to talk to Lulu (Chicken, good).
I only discovered the inserts were porous (but no water yet!) after I cracked the vent open TBH. I thought if I vac from the vent there's airflow due to the inserts. I mean the darn thing is a lard-ass, it's over a kg overweight, about 1.2kg, on a 7.6kg base weight. In percentage terms it's a Porker.
Cheers on the paint comment too, I might just sand it back a smidge with 240 or 400 grit or something. Sounds like it's going to be a long project .
Here's something may be worth trying.
I bored a hole in the front of the board (deck) and using a plumbers fitting and pvc pipe hooked up a hair dryer blowing warm air into the board. Vac pump on the other end.
Over a day it pulled out 800gr of 1100gr of water which got in.
The EPS soaks water up real fast and some is staying there forever and I'm talking about getting the vac on within 6 hrs of the holing.
If the water's been in there for a while it will be well soaked into the EPS.

Hi thanks for that, impressive! Did you happen to take any pictures of the setup please, specifically what brand of hair dryer . ??. Nah just hole sIze and fittings, if you have it, ta.I'd be a wee bit worried about it melting the foam though . I think mine (water) has been there a while, at least I'm guessing .

No pics sorry, holes around 20mm for inlet and sucked on vent hole with the vac. Had a plenum tank (4" PVC pipe capped) in vac line and nearly a litre of water in there. Wife's hair dryer......cheapie.

cheers, my smiley 
about the hair dryer brand turned into question marks ??, was actually supposed to be tongue in cheek. no worries, thanks again, k.
