ᐅ Cracks in the plaster or masonry when heating the screed.

Today we noticed several hairline cracks in the plaster. These cracks were not present yesterday. Since yesterday, the heating program has been set to 55 degrees Celsius (131°F). I know the cracks can be filled and covered with painter’s fleece. But what happens when tiles are applied? What concerns me even more is that the cracks in the partition walls go all the way through to the other side. We have HBL blocks.

We already terminated our contract with the general contractor, who was supposed to deliver a turnkey build, some time ago because they refused to fix many defects.

But the cracks are on both sides of the walls, so the bricks should actually be cracked.

As long as there are only stress cracks in the plaster, which can appear on both sides, I don’t see any problems. However, if the cracks are in the masonry, then something is wrong—something serious. But I can’t imagine that being the case right now.

Are we talking about partition walls, load-bearing walls, or exterior walls here?

You can get some plaster and apply it over the cracks in various spots. If the plaster cracks again, then you have a problem. This is often used as a method to monitor the cracks.
