Gyvlon screed

[Stone]

Hi all,
does anyone know if anhydride screeds should be used in bathrooms?

 

[DHTiling]

They can yes , but i always make sure the area to be tiled is waterproofed , i use membrane..

 

[White Room]

As above....

 

[Stone]

So just to clarify, the membrane I use for the wet room tray in the room should be continued through the whole floor area?
Is this a personal preference for peace of mind or does this need to be done?

 

[White Room]

Yes to cover the whole room....it needs to be done because of the type of screed.

 

[DHTiling]

It is very wise to do the whole floor area , Anydrite is not a fan of getting soaked when tiled.. this could cause suplhate issues ..

 

[Stone]

So I should sand the floor apply primer and then completely cover the whole floor in membrane?

 

[Stone]

Can decoupling membrane still be used?

I heard of a building contractor that shutters off the wet areas and only pumps the gyvlon into the dry areas of the building and uses sand and cement in wet areas instead.He may do this then to avoid using the membrane or maybe he has had a bad experience with the anhydride screeds and returned to traditional methods in certain areas to avoid comebacks??

Personally I would want a standard screed in the bathroom....

Personally, I would want a standard screed in any room.

Anhydrite n screeds should not be designed to falls and should not be used in areas where they will be permanently wet (swimming pools) or in areas where intermittent long term wetting and drying may take place.

a suitable floor covering should be applied I order to manage the risks of wetting in bathrooms etc.

Yes

I have heard of people using membranes for wet areas, as manufacturers of Anydrite screeds we don't recommend their use in permanent wet areas or areas of long or persistent wetness. Most wet areas are genarally laid to falls, and this is best achieved with another type of screed
