Re: tanking - why?! | | Tile grout is water resistant not waterproof (unless you use epoxy) the same goes for adhesive.
In a normal light duty shower area you will probably have no problems with the tiles but when it comes to heavy duty shower use ie, big families using the shower.
Then you start to have problems, the water will not have time to dry and it will work its way through the grout and to the adhesive where it will have no where to go except the surface to which the tiles were originally fixed. If it is plasterboard then it will become wet and the board will break down.
Tanking the walls will provide a waterproof barrier that will stop water getting to the boards.
IMO tanking is not necessary on low use domestic showers. As long as good quality adhesive is used which is suitable for the job such as Bal White star and grouted with suitable grout then all will be fine.
Depending on the tiles being fixed you may want to use a bagged adhesive if fixing larger formats. I know a lot of tilers here only use bagged adhesives but thats down to personal preferences. |
