Have wet coating on floors but want tiled with under floor heating. Some plumbers claim that the coating acts as a membrane others . What is correct?
Will a wet coating cause the casting of ” swim ” in the water? Can this be combined with under floor heating lead to ” basement smell” ?
Generally works well as flooring membrane – if it is waterproof so it is . It is actually the best membrane one can get. Have you showered on the floor earlier and there have been leaks , then the membrane in order. Yes – the casting will be moist. But that does not mean there is anything wrong in it. And when you then come to the heating element , it tends not to cause mistake, but there are some heating cables that are more sensitive to moisture than others.
Contact your electrician or those leading heating to listen more closely. There have been some complaints about this. Smell I have never heard of. It’s not so much water that it causes odor problems. Then it must be other reasons. The water will drain out . NB ! This is of course dependent on the fall of the coating down to the casting . It is not so easy that you can cast to fall over – it is the membrane that must have fall. Is the membrane coating flat must take it up, molding below, so that it becomes vertical .
What you must not do is let the old coating lie , cast again and add new membrane on top. When the shutter to moisture between two membranes. Then it can become smelly. There will only be a diaphragm in the floor. Remember good compression of concrete look BVN 31020 . ( screeds ) .
