Humidity & Temperature during epoxy curing

[_andi_]

Hi,

so the datasheet says less than 70% rel humidity and 20-25C optimal temperature and 18C/65F minmal temperature, demouldable after 36h.

I'm doing Epoxy/Fibreglass work on the bottom of my boat which is on a meadow by a river, never ever will this window of temperature/humidity occur for 36h straight in central europe. Everything has been fine so far. But the nights get more nippy and humid.

Now I'm wondering with what I can get away with. I'm contemplating something like starting late in the morning after all morning dew dried out, apply a couple of layers wet-in-wet until like four in the afternoon, stick on peel ply and repeat the next day.

Has anyone some guidance/experience on this? The total cure time doesn't really matter, I won't splash the boat until next year but I'm concerned about the bonding between layers.

Thanks, Andi
