CURING POR 15

Hi Folks

I've used Por 15 in the past. I do most of my work over the winter, and I have found that my shop becomes bone dry with the heater running. When I used the product last time, it took almost a week to cure, presumably from the dry conditions. Since the Por 15 needs moisture to cure, does anyone have any suggestions, gained from experience, on how to make this product set up? I was thinking about misting it with water to help it cure. What are your thoughts?

Thanks
