hot coat - just double checking

i want to hotcoat my board today, but i just want to be sure on the approx amount of resin/styrene/catalyst i need. it’s a 5’10 single fin. 15.5 nose, 21.5 middle, 13.5 tail, 3 thick. sun just came out, patchy clouds, about 65 degrees and probably 60% humidity? (doing this in the backyard). so i was wondering about how much resin i should use, how much styrene hardener i should mix in, and about how much catalyst. THANKS!

oh yeah… im in newport beach, california if that helps

i just put on the hot coat and in came out good. but is there some ratio of resin to hardener that i can use to approximate how much i need? like a quart of resin to an ounce of hardener or something?

Using hotcoat resin (especially if you put a extra amount of surfacing agent in your batch)I would go with 15cc/qt…@ 65 degrees +outdoors 60% humidity with 16oz/pint(should be plenty) of sanding resin, I would go with probably 9 or 10cc cat…THIS SHOULD BUY YOU ABOUT 15-20MIN. BEFORE GELL TIME.Herb.

thanks… but one more thing. i dont buy sanding resin, i just get laminating resin and mix in some liquid wax hardener stuff to make it sanding resin. is there some kind of ratio for that stuff as well?

I tape this to my shop wall. For sanding resin to gloss resin, I add this range of stuff to lam resin: MEKP Min , 0.3% , 2 drops / oz , 0.09 oz /qt Max , 0.9% , 6 drops / oz , 0.27 oz /qt Air Dry (Wax) Min , 2.1% , 15 drops / oz , 0.69 oz /qt Max , 3.6% , 25 drops / oz , 1.14 oz /qt Styrene Min , 5.0% , 35 drops / oz , 1.60 oz /qt Max , 10.0% , 70 drops / oz , 3.20 oz /qt Full eye dropper squeeze=25 drops. 1 oz = 700 drops. I interpolate for temperature, thickness and cure times.

I mix 1.5 ounces of sanding or glossing resin per side, per foot of board. Similarly, I mix 1.5 ounces of lam resin per side, per glass layer, per foot of board. Example 3 layers of deck glass times 9 feet of board times 1.5 oz of resin = 40.5 ounces of resin. Good luck.
