Toxic warfare

Ok, so here's the deal, Kari and I were putting in the concrete backer board last night for the shower enclosure. Part of this was that we had to cut the corner folds of the pan liner and glue them together with this special glue. The glue is similar to PVC glue. If you are familiar with it then you know it is smelly stuff when you are outside, now imagine using this stuff inside, in a little bathroom. At first it wasn't so bad, then Kari said she had to get out of there. After putting up one board I decided since I was feeling a little dizzy and my head started to hurt I should probably get out of there before I was unconscious. So then the plan was short bursts, 10 or so minutes, that worked for 2 more boards. After that I figured it was not very healthy to continue exposure. I will do the other 2 corners and the last piece of concrete board tonight. Maybe I should go invest in a gas mask or something.
