ᐅ Is it allowed to install tiles on newly laid screed?

Next week, the screed will be installed in the new build. Until now, I thought it needed to dry for at least 6 weeks before the tiler could start. Now the contractor says it can be done as soon as the floor is walkable, and besides, the tiler is available immediately, so we should arrange to get the tiles as soon as possible.

So it’s either immediately or after 6 weeks. Where is the logic in that, and how can the screed properly dry with large tiles (60 x 60 cm / 24 x 24 inches) on top?

Obviously, the screed can be walked on after 1 day. Then the tiler will start. He will have 3 days to install the floor tiles. Tile adhesive will be used. Grouting will not be done yet. Then everything should dry together. After 2 to 3 weeks, the underfloor heating’s initial heating program will begin. The tiler has been using this method for 20 years, and it is definitely not unfamiliar to the largest tile supplier in the region. This is how it will be done now.

That can actually be done that way, as long as the joints remain open.

Wet-on-wet, as tile installers say

Are no uncoupling mats being installed?

Between the screed and tiles? Why?
It would be interesting to know how the waterproofing is handled in wet rooms... No moisture should pass through there, but it is supposed to.
Or do they leave out the wet rooms and complete them later?

When we took over our house a year ago, the tiles in the living/dining area were cracked in several places (see example in the picture). The expert insisted that the screed probably wasn’t fully cured when it was installed. To be on the safe side, decoupling mats were laid before installing the current tiles. Since it’s not a new build, this probably wouldn’t have been necessary... but better safe than sorry 🙂

Crack at the living room/kitchen transition:

Tile floor with a pattern of square tiles; shadow of a person with a camera.

Decoupling mats:

Bright interior under construction with large windows; floor shows round insulation pad patterns.

Partially tiled living room:

Room under renovation with unfinished floor: blue underlays, yellow spacers, bucket, glass sliding door.

We only tiled halfway up the walls in the bathrooms and have had no issues with moisture.
