Heating the Floor Screed (Estrichtrocknung)

We have a schedule with one of the Technician from the manufacturer of our heating system, Vaillant. One way to fully dry our flowing screed is to turn on our underfloor heating system.

On our Vaillant Heating System, the screed drying function is used in a fresh laid heating screed in accordance with the rules "Dry to heat". The flow temperature of controlled heating circuit is independent of the outside temperature regulated according to a preset program. The start Temperature is 25 ° C.

Drying of Flowing Calcium Sulphate Screeds (Trocknung Calciumsulfat-Fließestriche)

After the delivery of the floor screeds, we are not allowed to get in there for atleast four days.

During my research, I was able to stumble to this helpful article from Euromortar.com. It says... "Correct drying is therefore essential for flowing screeds so that they are speedily ready for application of surface treatments or coverings.

The following points must be observed when drying flowing screeds:

- The screed must be protected from draughts for about 48 hours after application.
- Intensive ventilation is required from the 3rd day onwards. The water absorption capacity of the air is dependent on the weather, e.g. on the temperature.
- Ensure that precipitation cannot enter through the open doors and windows.

Heating Floor Screed:
Drying of heating floor screed is accelerated by heating it up. The screed can dissipate its humidity faster and the air can absorb more moisture as it is warmed up. Hence, the drying time for heated floor screed depends on the nature and means of ventilation as well. Continuous closing of the windows to avoid heat loss simultaneously prevents drying of the screed. A constantly tilted window is also insufficient to quickly dry the heated floor screed.

We started the ventilation on the fourth day after the delivery/application. Here are some pictures as  of date.

Floor Screed is in the House! (Endlich Estrich ist da!)

Today at 8:30 am, I was already at the building site waiting for the Floor Screed Troop. While waiting, I took the opportunity to take pictures with measurements for the important corners where our underfloor heating is located.

At around 9:20 am, A&D Troop arrived and started to check every room of the house. They measured how many cm of screed we exactly need. After 20 minutes, the first floor screed pumptruck arrived. When they started putting-in the floor screed, it was really fast. We have flowing calcium sulphate screeds. This is the best floor screed for houses and buildings with underfloor heating.

The troop was finished at around 2 pm.

These are some pictures during the delivery and application.

Floor Screed Delivery Schedule

I was able to contact A & D (floor screed company) and requested for an earlier-than-planned delivery of our floor screed. Since everything is ready, we would love to have it the earliest possible. Unfortunately, A & D is already fully booked. That means...two weeks of waiting, sigh*.

In the meantime, hubby is testing and running the underfloor heating to make sure that everything is all right.

Underfloor Heating Pipe - Final Installation (Fußbodenheizung Finale)

Hubby was with his work very busy. He was always out-of-town thus he was not able to continue working in our building site.

It is again weekend and we are hoping that this will be the last installation of the underfloor heating pipes.

Hubby continue installing the pipes at the basement. In the afternoon, his helper arrived and started to fix the end of the pipes to the underfloor heating manifold. He also started to work on the bath towel radiators. They were able to run water on the pipes and reached 35 degress celsius at the ground floor. They would like to continue the test on Monday.

ProHaus Building Consultant Visits (ProHaus Ausbauberater Besucht)

It was a surprise that we received a call from our ProHaus Building Consultant today. He said that he is on the area and he would like (if it is possible) to see how we are doing with our house building. Ofcourse I went directly to the house and he checked how the underfloor heating pipes were installed. There are some things that needed to follow in order to avoid issues later. For example, there should be no underfloor heating pipes under the first step of the staircase and so on and so forth. Good thing that everything is all right. He also took some pictures and measures the needed distances.

Below is the picture that I took after the meeting. As you can see, we still have the building site stairway. After the floor screed, ProHaus will visit us again for the measurements of our wooden stairway. The delivery will follow after eight weeks.

Bath Towel Radiators Installation (Badetuch Heizkörper Montage)

Before the weekend arrives, hubby installed the bath towel radiators on the bathroom wall. In this way, our heating and plumbing helper can install it directly on the underfloor heating manifold, on weekends. That's the plan.
