Hotcoating the Longboard

For some reason, the photos I took didn't come out very clear. So, this is what I managed to salvage. Next step.... Sanding. I hate sanding!

Surfboard Glassing Guide

Here is a surfboard glassing guide/schedule that I put together. I wanted a chart that would help me figure out the amount of catalyst to put into the resin - based off of the outside temperature and fall within the time frame I wanted before it kicks. It's kind of been a guess work for me, so I am hoping this will help out.

This guide is broken down in three sections - Lamination, Hotcoat and Gloss. The measurements are in CCs instead of drops or percentage. Also included is the amount of Surfacing Agent (Wax) to put when making the hotcoat. I modified the amount of MEKP CCs per ounce of resin to fit with the kick times I wanted. So adjust the amount of catalyst to get different kick times.

Anyway, if you guys use this guide, let me know if you how it works out for you. I haven't tested all measurements yet, so make sure you do a test batch. Depending on many factors like weather and the amount of pigment you put into the resin, the outcome will definitely vary. So... do this is at your own risk.

If you can, post your experience, comments or suggestions to make this better. Hopefully it will help out other fellow DIY surfboard builders.

It's Hotcoat Time!!!

It turned out to be a lot easier than laminating. I ended up using 3 teaspoons of white pigment to get it a little more opaque. Seems to be just the right amount.

Here is the Hotcoat Mix:

Resin: 32oz
Catalyst: 25cc
SA: 10cc
Pigment: 3 teapoons
Env Temp: 76 F
