Yep, I have an old scenery book the says mix asbestos with the plaster to slow the set time and add strength. <br /> That goes back when DDT was considered safe. I saw an old promo film on the safety of DDT. They showed kids swimming at a city pool and then along comes the DDT spray. Then there's the scene of people at a picnic table eating and being sprayed with a cloud DDT dust! <br />
