Hi I had a plasterer who started in July took off half the base coat and all the top coat said he couldn't get it all off as would damage the bricks so painted it to bond then scratch coated and top coat. Seems ok. He cannot get all the front coat off the other side so i have not seen him for 2 months having called texted. With the weather changing and only a scratch coat on what affect will this have on the new plaster inside when it rains?? Please help Also the finished side hasn't been painted yet?
