Construction costs are currently skyrocketing

Quote provider: “GU builders often opt for Q2 and fleece for financial reasons and then wonder about the result, whereas Q3 with heavier fleece is definitely the better base for painting.” He was also a good representative of his field and was able to “sell.” :)

I am a layman regarding this topic and therefore a bit clueless. A family civil engineer also advised me to go for Q3 plus fleece.

Ditto. We were also very skeptical about painter’s fleece. Such a thing is unknown in our country of origin (Poland). There, they usually work with smooth or fine plaster, so the walls can be painted afterwards. That was originally what we wanted as well. Unfortunately, the acquaintance had no available appointments. But when we were painting and saw the result (Q2 + painter’s fleece), we were convinced.

Why not simply sand down and paint Q3? [Vlies] is really unnecessary and expensive.

Why not just sand Q3 smooth and paint it? Fleece is really unnecessary and expensive.

The question is how good Q3 will be. You can also paint Q2 after filling and sanding. However, you will see the texture changes between filler and plaster.

Actually, last year I inquired about wholesale basalt chippings 16/32. However, I wanted to use them to decorate the garden and driveway. Net price per ton 25€. About 500 € travel costs per truck. And I only needed 5 tons. It really depends on how far the trips are and where, for example, the quarry is located.

We paid 28€ per ton for natural chippings.

Fleece acts as a crack bridging layer and with point loads you don’t immediately see every dent. Standard Knauf MP75 plaster is relatively soft. In any case, fleece has its justification. Unfortunately, I only did that on the upper floor, applied Q4 filler, and then 190g fiberglass fleece. At the time of the ground floor, I unfortunately couldn’t get any people.

The problem with fleece is that it cannot be repaired if a settlement crack does occur. I have a large crack in two rooms, where the fleece has torn as well. It can only be properly fixed by sanding down the entire wall.

In the course of the repair, I will switch to [Rollputz]. It has other disadvantages but can at least be repaired locally.
