Had a bit of a nightmare yesterday when laminating. I was doign a regular free lap
Layed up a layer of 4oz on the underside of the board. Proceeded to laminate. Managed to work all the resin over to and off the rails.
Was in the middle of wraping the glass around the rail and on to hte deck when the resin kicked…arrrhhggggggg.
The upshot of it is that one side of the deck (next to the rails has a load of horrible lumpy bits of glass and resin beads.
Anyway. I lamed the deck with one layer of 4 oz leaving the cloth hang loose. I then ground down all of the big lumpy bits.
I propose to do the following.
1 - Hot coat the deck
2 - Sand the hell out of the deck especially at hte rails where all the lumpy glass is. I’m gonna use 60 grit and go all the way through the hot coat untill the weave is starting to show.
3 - Then I’m gonna do a 2nd layer of 4oz on the deck and hopefully proceed as normal.
IS THIS THE CORRECT THING TO DO. Any advice would be appreciated
That’s not what I would do. No need to apply the hotcoat resin now. Sand the lam smooth and get rid of the bubbles. Treat those as ding repairs and patch them with fiberglass and lam resin. Sand smooth. Lam the deck giving yourself more time. The deck takes a bit more time because of the extra layer of glass. Get it all nice and smooth then hot coat it. Should be no problem. Mike
Your only sanding down the lap line and the de-lams and bubbles. Right? Not the whole lam. Anything that sticks up gets sanded down. Yes, you will get some gumming up. If its really big you can use your sureform to take it down or a razor blade. Patch the holes and get it as smooth as possible. Lam the deck.Then hotcoat it. Mike
WWWTTTFFFF and WHHHYYYY are you still using catalyzed resin, when there’s UV cure? Do youse troglodytes have to glass at night?
Nah nah nah. C’mon, I’ve been caught by quick setting just like you guys. I have my catalyst chart on the wall, syringe on the shelf, and all that. But now I use UV cure and that’s all there is to say. Wanta take 45 minutes on a single six ounce lam? Go right ahead! Wanta take an hour and a half? That’s okay too! Then just drag the rack and board into bright sun and 15 minutes later you’re glassing the other side.
What used to take days now is over in a morning. The I go surf, which (despite actually liking the creative part of makign a board) is why I do all that work. Let’s not lose sight of the end use…
Howzit pauluk, I would think you should be able to order the UV catalyst powder from the US and make your own UV resin. Next get some flourescent light fixtures and UV bulbs for a light box. Living on Kauai we get as much or more rain than almost any place on the earth and I have lights to kick UV resin and they work just fine, rain is not a factor any more. Aloha,Kokua
