Hi All,
Quick question for you regarding plastering technique. I have a room with a number of chased runs containing electrical conduit that I need to plaster. They are a couple of feet long and about 4 cm deep. I tried to fill one last night but by the time I was half way along the plaster I had mixed had dried out. Is there any easy way to extend the time plaster take to set to buy me maybe another 30mins or so? I was surprised to see how quickly it went off! I think also the fact that I mixed too much in one go probably didnt help.
Thanks, Matthew
