LESS CONSTRUCTION TIME, MORE TURNOVER AND NO STRESS!
MAKE OPTIMUM USE OF TIME IN INTERIOR WORK WITH RETANOL®!
In order to determine the potential of a shortened and predictable drying time for the construction process, the process must first be visualised. The main trades in residential construction are shown below in a process chain, or as they say in lean construction management, in a “train”. Thanks to the cooperation with our partners, this process chain has been continuously improved over time with Retanol® screed. The result is 12 weeks of construction time to complete a flat from the start of drywalling to cleaning. In this example, the time between screed installation and floor covering work is 1 or 2 weeks.
UNTREATED SCREED VS. RETANOL® SCREED
Cycle time Retanol® screed
With a Retanol® screed, you can save 8 weeks without a buffer and 4 weeks with a buffer compared to a construction process planning with untreated screed, with an average investment of 6 - 7 euros/m². This cost/benefit factor cannot be realised with any other system in the construction industry. The Retanol® screed system is your most effective way for more sales and less stress.
Cycle time untreated screed
If we now assume an untreated screed with a drying time of 6 - 8 weeks and a maximum screed thickness of 6 cm, the process chain is increased by 8 weeks and, in addition to idle times and long costly heating phases, still carries the risk that the construction time cannot be met due to the unpredictable drying time.
UNPREDICATBLE DRYING TIME UNTREATED SCREED
Untreated screed as the trade with the greatest risk in interior work
One of the main reasons for unpredictable drying times is the exponentially increasing drying time depending on the thickness of the screed. This not only results in long drying times, but also increases the risk of exceeding the planned construction time. A drying time of 15 weeks with a screed thickness of 8 cm is simply no longer feasible with today's construction times. A Retanol® screed can perfectly anticipate the fluctuations in screed thickness caused by structural tolerances, for example, so that you can always plan a predictable drying time from the third day into your construction process.
SCREED INFLUENCE FACTORS
The following influencing factors have an effect on the drying time and screed quality:
Aggregates
As a classic wet screed that is produced on site without production supervision, an untreated screed consisting of sand, water and cement has many disadvantages. Inadequate aggregates and unsuitable framework conditions then lead to long drying times, which can no longer be afforded nowadays. With Retanol® screed, you have the opportunity to turn the disadvantages mentioned above into advantages as compared to the status quo. The influence of the aggregates on the screed quality is described below.
Ambient climatic conditions
The ambient climatic conditions depend on various factors.
- Temperature: inside/outside
- Air exchange & circulation
- Humidity: inside/outside
As a generalisation, it can be said that ventilation can be started 24 hours after screed installation with a Retanol® screed. Then ventilate the screed 3-4 times a day for 30 minutes each time. This removes the excess water that is not converted during hydration from the screed surface.
