I was lucky to get a Clark 88H ultra light blank after it closed. I purchase at the same time a three-gallon set of SB-112 Epoxy with a ratio of 2-1 to do some of the laminating. I also purchased a polystyrene blank. Both blanks are shaped and ready for glassing. I plan on glassing the boards with Epoxy laminate under a polyester laminate and sand coat. The two blanks are both 8’-1" long and 23" wide shaped like my Nugget but wider. The polystyrene is 3-1/2" thick and the polyurethane is 2-3/4" thick. Both shaped blanks weigh 5lbs. at this point. My intended glassing will be as follows.
1- I will laminate the bottoms with 4-oz S2 glass and Epoxy with free lap the rails.
2- I will then laminate the deck with a poly/carbon cloth with epoxy and a cut lap.
3- I want to then laminate the bottom with 2-oz E-glass with Polyester resin with free lap.
4- I will then laminate the deck with 4-oz E-glass.
The sand coat will be polyester resin.
My questions are;
1- What preparations do I do between the Epoxy and the Polyester layers.
a- Do I just wipe the epoxy laminate with alcohol before I laminate with the polyester? b- Do I sand the wipe the epoxy before....? c- Do I lay a layer of epoxy sand coat between so I can sand and wipe so I do not compromise the poly/carbon laminate? d- Do I lay a layer of 2-oz glass on the poly/carbon when I laminate so it can be sanded with out touching the poly/carbon layer?
2- I have access to a large oven to cook the Epoxy to speed up the curing time. The oven is set at 150-F°
a- What knowledge do you have on this? b- How long would you suggest cooking the epoxy? c- Would I check on it every 15 min or every 30 min? d- Would I place it low at floor level or high at 6'
3- Does the Epoxy have to be completely cured before I sand/wipe and laminate the polyester laminate?
4- What would you wipe the Epoxy down with between laminates or epoxy and polyester? I have been told to use alcohol, acetone and Spick and Span. What is true and what is myth.
I will be laminating the bottoms this Thursday Night with the Epoxy. Any help or information would be greatly appreciated.
Happy New Year
