Hi, I have hot coated a kiteboard to test before doing it on a bigger job.
I mixed coating epoxy and applied rather thickly with brush directly onto finished laminate ( 200g twill glass).
It flowed out and filled weave nicely. After 18 hrs in 19c garage with controlled humidity, it is cured, but has waxy/ greasy surface. I tried cleaning an area with acetone and it did not help.
I mixed using weight ratio with compensation for different density of hardener and epoxy. This,would mean I had a little too much hardener because it is lighter.
Could this be problem.
Epoxy is one year old. Been in cool dark place. It Looks clear and ok.
Please advise, is this normal? I was expecting glossy, clear, hard surface.
Regards, Tom Waldner
