hopefully this will be my last post on here before i complete the board. i feel like i’ve posted way too many times already :-/…oh well. anyways, i am about to do the hotcoat probably tomorrow, temperature/time permitting. anyways, i have a few questions before i go about laying the hotcoat down:
should i be safe with these amounts for a 9’8 board: deck- 25-30oz/10cc cat./14cc wax…bottom- 20-25oz/8ish cc cat./12cc wax…i’m judging those close to surfersteve’s site.
i messed up when i wrote out my name and board dimensions near the stringer. i have thought about painting over that with white paint, printing out the dimensions on some lam paper i have, laying them on the lam’d board and laying a piece of my 6oz cloth on top of that spot and lam it with some lam resin to fix it. can i do this? will it work? then continue on with the hotcoat?
Howzit barefeet. Use 15 cc's catalyst anda little more S.A.. I eye ball my S.A. but always use 15 cc's catalyst no matter what size board. Shorter boards use less resin but it takes less time for brushing, bigger boards more resin but same cat amount gives you more time for brushing. This is how I do it but it's not written in stone.Aloha,Kokua
Barefeet: 30 oz resin and 10 cc catalyst comes out to 1.1 percent catalyst. I do wish you keep consistent units!
Anyway, I have read that PE resin is strongest at 1 percent catalyst ratio… and been told to limit styrene to 10% max.
You should be good to go, though if you thin out 30 oz resin, almost 4 cups, you’ll have enough for at least two hotcoats. I can lam a nine footer (6 oz) with less than 4 cups; the hot coat shouldn’t take near as much resin as a lam.
This maybe shows that you should be using UV resin. Pour it into a container, add SA and mix. Pour onto the board only enough, and you can use the rest for the next hot coat.
Suggest about 2 cups of styrene-thinned resin may do an adequate hot coat, but it will depend how dry you did the lam, and how much you like to waste on the floor.
