Lately I have been repairing a number of firewire’s with delams.
It appears that there is a problem with the outer glass separating from the divinycell which looks to be painted ?
Has anyone else experienced this ?
over the past year or so i have been fixing alot more firewires than normal and most of them with delam problems, most of the delams that ive been dealing with though are ones that seperate between the eps and the divinycell, most of them had wate in them so thats why it seperated but there have been some where there was no water in them at all and cant figure out why it delamed, the only thing i could think of is people just stomping on the board and somehow breaking the bond between the laweyers, just a guess though. and all the delames where it was just the top layer delaming from the divinycill there was no water in those just seperation between the layers
Were these fairly new boards? Or older ones with plenty of use?
most of the ones that i worked on were were less than a month or two old, the other thing that i see happen alot with em is where the people put there back foot, that area will crack all the way down through the diviycill just from everyday surfing
they wernt new, but not that old either. There were a few delams with water present.

I’ve noticed they have some sort of paint layer between the divinycell and the glass. Almost has a chalky-dusty look and it separates the two when creased. Can’t say that the crease wasn’t going to happen anyway and I can see how this would get water in the gap. Not going to add to the overall strength.
I’m sure Bert won’t be too thrilled to read this thread, but if he does maybe he will shed light on what is being done to correct it.
So basically you have a “bomb proof” board that costs a lot experiencing a different kind of problem for its approach to make it ‘bomb proof’?
The use of balsa, divinycell, eps, and cork for that matter, are all focused on their ability to recover from compression. The alternative approach (from standard hand layup) of construction deals with a different methodology to what engineers term “energy management”.
The ‘new construction’ for surfboards has become a (denser) veneer layer of choice over a very light core. In practical terms, it is like throwing a 4’x8’ piece of plywood over a big block of very light styrofoam in order to make a bridge you could drive over without the tires denting it.
As you guys are seeing, this approach is all about the bond.
Divinycell/Airex/Cleducell/PVC foam is strong, but not indestructible. Don’t even ask about it being environmentally responsible…
P-co, when you noticed the chalky layer, did you pull test it to check the bond?
Something like this is a major bummer for a company that puts so much time and effort into producing what they hope will be viewed as a superior product.
D/S, many of the delams had chalky paint. I did do a pull test and the glass stripped away very easily, with the paint attatched .
I stopped pulling glass away and feathered in repair with a coarse grit sanding disc,a la the way the "Boardlady" shows on her website.
So far I havnt had any returns. My take is a bonding problem with the paint & divinycell ?
