hey guys i need some help with a delam on my board. its on the deck so it doesnt matter if ts a bulged resin blotch or what. i know theres a lot of different ways, and im pretty skilled with glass and repairs. its about the size of a cd disk. should i rip the glass and reglass it (rather not) or drill holes and fill it with resin? i rather fill it with resin but what resin would be the best? any help or suggestions would be appreciated
neither. and filling that bubble with resin is NOT going to fix it. You'd be better off doing nothing.
Cut out the section of glass and patch in new cloth and resin. I'd cut a section 1.5x the size of the bubble. Those oscillating multi-tool things work good. No need to cut into the foam. Sand edges, recoat. Consider glassing it heavy if the delam was an area that was bombarded with pressure.
let me reiterate that...
i meant drill holes squirt resin in there and press it until it dries to bond the glass to the foam
yep...cut it and reglass it. If your pretty skilled with glass and repairs, and the delam is only the size of a CD, then this a relatively easy fix.
Often with delam spots, the foam will turn out to be caved in underneath so when you cut out the bad glass, you may find that you need to build up the depression (i use resin and q-cell mixed to a creamyh/foamy consistency for this) before you glass it to make it flush with the surrounding deck.
I know what you meant. Seriously, don't waste your time. The glass is already saturated with hardened resin... which separated from the foam, right? Well your foam is either compressed (likely) or expanded (possible) in that area. So you'd need to bring the foam to the lamination - not vice versa- if you were to fill the cavity. Best to cut out the section and relaminate it. Basically your blank is different now compared to when it was originally glassed. Don't stretch the original lamination to fit its current shape/state.Originally Posted by mexsurfer
yea that makes more sense. and yea that foams pushed in. what do you guys think will happen if i leave it? do you think it'll grow or just stay soft. id need to buy more resin which is a pain.
The delam will definitely grow of you don't fix it. Any flex in the board will pull the glass away from the foam fairly easily once the bond is broken. Cut it out with a dremmel or utility knife and reglass the area.
Or just leave it go. That's always an option, delams don't take on water but shorten the life of the board.

Another option is to cut a flap, clean out any loose debris, pour in lam resin, flap it back down, weight it down so all the excess resin squeezes out, wipe clean, let it kick, sand and patch the flap line, hotcoat, sand. I never fill in the dent... not worth the effort/weight/bulk.

i guess im gonna cut it out and re glass it. ill put up pics when i get a chance
Yup- reglassing is the way to go- make sure you cut all the delam out-so the edge of the old glass is still secured to the foam. I have never had any success with the cut/slit/drill holes method and fill- always looked like garbage too. The only time it worked out ok was when using laminating resin...
I would either let it go or cut (possibly fill with qcell) and reglass. although- this adds extra weight. After doing quite a few of these repairs- I think it may be better to just leave it...
