Yup the powder everywhere from sanding the joint compound about killed me. He did it once and left me the mess to clean up. I was mad and told him AGAIN he can't use that in the house and I shouldn't be left to clean up/breathe in the mess. He put a 2nd coat of joint compound on and I left when he was going to sand b/c I was already having problems from him doing it the 1st time. Then I come home and he used it again and left a huge mess of powder covering the kitchen, dining room and hall. He had not covered anything and left it all for me to clean up. He didn't even wipe up the floor and he tracked it to the rest of the house. I spent hours wiping everything down. Including all surfaces and trinkets. UGH We had this argument the year before when he insisted on using the power sander. He is so stubborn and it was completely insensitive. Of course I have other words used to explain the situation, but I can't post those here. Oh and my daughter has asthma. I still get angry thinking about it.
