Hello forum community,
I have received a quote for fast-drying screed with an additional cost of 1500 euros for about 120 m² (1290 ft²). According to the offer:
The cement-based fast-drying screed (VELOX 7 cement fast-drying screed) offers, compared to the usual screed system, the advantage that it can be walked on 24 hours after installation and can bear 70% of the contractual load from the 4th day after installation. By using fast-drying screed, you can save approximately 4 weeks of drying time.
From a financial point of view (4 weeks), I would save one month’s rent and one month of loan interest, which amounts to about 1900 euros. Would this be worthwhile? Especially since I’m not sure if the following trades would be available in time, and the time gain might be lost.
According to Google:
A conventional cement screed is walkable after about 3 days and can carry light loads after about one week, but it only reaches readiness for covering or full load-bearing capacity after at least 4 weeks. The screed is ready for covering when its residual moisture corresponds to the ambient air humidity.
During the drying phase, I plan to apply at least Q3 or Q4 level joint compound to the walls, meaning I would be working there after one week. Would this cause any issues regarding screed walkability?
P.S. The drywall installation inside the house is already finished, I hope this is not a disadvantage.
It’s not like I can just spend this extra amount without thinking. I’m still unsure. Who here has experience with this?

So, would the house actually be ready to move into four weeks earlier? In my case, some of them couldn’t even start yet, so a fast screed wouldn’t have helped me at all.
