Hello!
We have a basement that isn't drained, but there is floor heating, so it's about 15 degrees in the basement, yet the walls still get cold during winter.
I spoke with a contractor to book a time in February. He also said that it might take longer for the plaster to dry and can be difficult when it's below freezing outside and the walls are cold.
It's been more than a year that I've waited for the contractor and can't wait any longer, so I booked a time in February anyway.
I understand that it might not be wise to plaster in the winter, but what do you say?
