Hi, I had my hallway walls plastered last week. Before the day had ended i’d spotted cracks all over the place. It’s pretty bad. The plasterer says it’s the heatwave and walls are drying too quickly. I agree to an extent but I also think he used a guy that wasn’t as good as he needs to be as the areas he was working on are worse than others he didn’t work on. What would you say is the best way to remedy the problem? I’ve added a couple of photos, many of the veins you can see are actually cracked.
