Howzit DMP, I bet your dad loved the smell of poly resin as did all of us older generation surfers. That was something that hit you when you first walked into a surfshop in the days of yore. Back in 71 I was glassing for Rich Parr in Honolulu on Queen st. Tfactory was the second story of his retail shop and he had cheese cloth over the windows to keep the dust out so the gloss work would not get dust in it.Well it was like the factory from hell and not only hot as hades but the fumes were almost unbearable and at the end of the day I was reeling when I left and the first olace I hit was the liquor store for beer which seemed tobe the only thing that got rid of the poly taste and helped with the chemical head aches. I kow we should have kept the respirator on the whole time but with the heat it justdidn't work that way. We were not as familar with the dangers of the fumes or contact with the chems in those days and I never saw OSHA show their faces ( probably to smart to come in) and the woners were just as dumb as we were about the chems. I stilldon't know if it was my smoking habit or the bad chems I worked with that was part of my cancer but I will just say to be careful and use all the protection possible when working with all board building materials and that goes for epoxy also. I have already been approached to build SUPs since there are a lot of them on the lake. But i told the guy that not only was I through with working with chemicals and now retired but that I could buy a china built SUP for probably what the price of materials alone would be here. The only resin work I do these days is repair work on our boats. Building boards is not ever goin to get you rich or even close. Even Papa Sau has to wait tables plus he is getting SS benefits and he gets lots of orders I have to give a lot of credit to Johnto makeends meetby only doing boards and there may be a couple more builders who can make it . You have a great job and I wish they would hire us haoles back when I was young enough to be get hired in your line of work but the only haoles were Bob Kaden and Bear that were in there and Bob transferred from Oahu and I think Bear was born and raised on Kauai which got him hired. As they say" don't quit your days job" . Aloha,Kokua
Understood! I used it on tints and opaques. Fin boxes, plugs etc. Anywhere I felt there would not be enough UV penetration for the resin to set throughly. All it takes is one tint or finbox to not go off. I also used it with certain colors of lams/logos. Especially yellow. Certain colored lams will bubble if you don't. I would mix up a little lam resin with catalyst . Squeege down my lam/logo and then grab my UV and laminate the board. Dark tints and opaques are too slow to go off with UV. I've done cutlaps with UV. It reqiures timing and technique. I prefer to do cutlaps in dark colors with catalyst and plain old Polyester, no UV. Almost never used catalyst on Hotcoats. If there was sun ora UV box absolutly no need. A UV hoatcoat done right sands better than a catalyzed hotcoat in my opinion. Catalyst in UV is just back up. It insures that it will eventually go off. If you understand UV there is no need for for catalyst in most layups and all hotcoats. IMO
Howzit McDing, After the second hot coat with UV went tacky I just went back to catalyst and when you think about it you only lose a few minutes because after the hot coat with catalyst kicks you just put it in the sun and it get rock hard. By using catalyst you don't have to even think about a tacky hot coat. I know a lot of the guys just use UV for hot coats with no problems but I had some problems and knew what to do to not have to worry about them again. Other than that I use UV and catalyst for the same applications as you do, to each his own when it comes to board building. If we all did every thing the same it would get boring and we would not be trying to find alternate ways to do things. Aloha,Kokua
I'm on the Resin Research bandwagon...no smell...low VOC...I live in So Cal....
There's some really good information on this thread.....I use UV cat for poly boards and repairs.....It's good stuff.
Bottom line....Poly stinks up my shop...UV or not.....my shop is connected to my house.....no poly no stink....
No stink...happy wife...
Happy wife = Happy Stingray....................
whoops....double post....
Howzit stingray, With your shop connected to your house you are smart to use epoxy and keep the wife happy also. My shop was abut 20 feet from the house and the trades blew the odor into the pasture behind the property. Unfortuneately the Kona winds blw the smell right into the house but I loved the smell. Aloha,Kokua

I have a high tolerance to chemical odors.....My family does not...........
dp… sorry
UV poly, lightly catalyzed… but didn’t need it. Light colors in tints, rather than pigments cure basically the same as clear, even in November in late October in New J[img_assist|nid=1055381|title=UV poly swirl|desc=|link=none|align=left|width=353|height=467][img_assist|nid=1055382|title=UV poly swirl|desc=|link=none|align=left|width=352|height=466]ersey.
