ᐅ Too little Ytong adhesive applied – is this a defect that needs to be corrected?

In the 36cm (14 inch) masonry wall, only about 20cm (8 inches) of adhesive was applied. This results in open joints of up to 12cm (5 inches) on the interior and exterior sides.

In the Ytong instructions, I always find that the adhesive must be applied over the entire surface, not just on 20 out of 36cm (8 out of 14 inches).

What disadvantages can be expected from this type of construction?

Is this a defect, and can it be corrected?

Yes, that there could be drafts, cracks might develop later, that these are mold-prone thermal bridges, or that the sound insulation is inadequate. If I were a professional, I probably wouldn’t have asked.

The plastering makes it airtight. We have the exact same construction, also with Ytong blocks, and with small or larger gaps. But we have been living in it for a year, no drafts, no mold at all. Really.

Don’t worry, the Nordlys sometimes has glitches in hot weather 😉.

At the core of what he’s saying, he is right. Shell builders can be a bit rough and work accordingly. But you don’t need to worry about that, and the plaster will make the house airtight.

Be glad if there is a lot of air and little adhesive inside... air is the best insulator after all 😉

For butt joints, this would not be a problem. However, here we are dealing with bed joints, which concern structural integrity more than watertightness. The adhesive is supposed to distribute the load. In this condition, the wall is less load-bearing. From my point of view, this is a defect.
