in our new build, we have two unheated basement rooms with calcium sulfate screed that has been drying for almost 6 weeks now. The rooms are 6 and 10 square meters (65 and 108 square feet) in size.
I would like to tile both rooms myself using tutorials from YouTube, Hornbach videos, etc.
My question beforehand is: What should be considered with this type of screed, besides, of course, ensuring less than 0.5% residual moisture? Are there sensible alternatives to tiling, such as PVC flooring?

Hello Andreas,
In practice, a trade like flooring installation will always present itself a bit differently than in a short video. Otherwise, specialized training and expertise would not be necessary if "knowledge" could be conveyed quickly through a video clip.
Accurate measurement of residual moisture is one thing. If misinterpretations occur at this stage, total damage to a floating screed cannot be ruled out.
Cleaning grind: this is always (!) necessary before further installation to remove adhesion-inhibiting layers. However, this step usually does not appear in so-called instructional videos.
Priming and filling: A bonding agent (primer) is mandatory. The stress-free curing filler is applied without trowel marks or scraping. This not only ensures the required surface levelness but also creates a uniformly absorbent surface for the later adhesive.
There is indeed a lot to consider.
I can confirm from my professional experience as an expert that even specialized companies do not always execute without defects, even though their experience did not come from videos.
Some trades require caution from amateurs—and an awareness of the risks they take regarding the expected results.

AndreasPlü12 Jul 2017 19:56Ok, then maybe a synthetic resin coating or vinyl floating floor would be better? As mentioned, it should be an affordable solution for storage rooms that are only occasionally used.
If the room is only intended for a secondary use, a mostly abrasion-resistant "concrete paint" from the hardware store, applied with a roller, is sufficient. However, this paint will be water-based and not resin-based. Nonetheless, this is adequate for the described application.

I was mistaken about the synthetic resin, I got it mixed up. I’ll look into a paint like that then.
