The company has investigated hundreds of bathrooms where craftsmen have done the job.
None of them have met the wet norm’s requirements for thickness of the lubricant.
– We have now tested hundreds of bathrooms. None of the professionals had managed to make the thickness according to the wet norm. The smallest thickness we found performed by professionals was only 0, 15 millimeters. The thickest was 0.45 millimeter, says Kolbjørn Mohn Jenssen to Click. no.
The requirement for the wet norm is 1 millimeter.
– An amateur does it carefully, reads the instruction manual and adds up to 5-6 coats. Professionals do not have enough time, says Mohn Jenssen.
What can the consequences be if the membrane is not thick enough?
– Membrane gives a certain amount of vapor resistance. If the bathroom is adjacent to cold rooms, the result may be mold damage, “says Mohn Jenssen.
Mycoteam became aware of the problem as more homeowners discovered mold damage to adjacent rooms. Mycoteam decided to investigate how thick the membrane was and what kind of impact it could have.
– Even in many cases where professionals know it’s going to be a check, they have not been able to put the membrane thick enough, “says Mohn Jenssen.

Look nice the bathroom was
Jørn Davidsen is Managing Director of Litex, which sells membrane panels for wet rooms.
He agrees that amateurs can do such a thorough job, telling House & Home that a craftsman has no other focus than getting the job done as quickly as possible.
The science councils will help reduce wet damage and disagree.
– Våtrom is particularly complicated. When educated to do this does not mean that it becomes easier for ordinary people, “says Lars Gulbrandsen, Senior Vice President, ..
A survey conducted by the housing magazine Vi i Villa in 2007, with nearly 2700 Norwegian homeowners, shows that only seven percent brush the bath on its own.
44 percent leave everything to professionals, while half of us prefer a combination.
– If you get the bathroom yourself, you have no guarantee , and they will be able to get less paid from the insurance company if there is any damage to the bathroom, “says Espen Krossli, general manager of the contract firm Oras, Telemark department , to Click. no.
He thinks there are unfortunately many good amateurs out there, but there are also many bad amateurs who should also seek professional help.
Not for amateurs
– We have had many assignments where amateurs have tried on plumbing, and then we must come after fixing. In general, I would like to say that the plumbing job is not for amateurs, “says Espen Krossli.
