Schluter Kerdi-Board - tank?

[Mossop]

I had a bathroom installer around and he said that even if putting up Schluter Kerdi-Board on the walls, as it's not much more expensive to additionally tank it with a paint-on tanking product he would do that.

I was wondering if there's any drawbacks to this? Perhaps Schluter Kerdi-Board wouldn't absorb a paint-on tanking product?

No, you tape the joints with schluter tape. The boards are waterproof. I would be checking that you are not being fobbed off. Have you seen the boards being fixed yet?

Sorry, just re-read it and realised you haven't had it done yet. Same applies regarding Schluter Kerdi keba band though for joints

He's obviously no experience in using kerdi boards.
Here's an idea that will save you some serious grief, call Schluter in Leicester and ask for the number of someone local to you who has been on an installation course at Schluter.

Hi,

As above Schlüter-KERDI-BOARD is waterproof, and only requires any joints (board, and floor to wall joints) to be sealed with KERDI-KEBA and KERDI-COLL. There is no need to apply additional waterproofing.

As Impish (thanks) states above feel free to call the office on 01530 813396 and we can advise further both you and/or your bathroom installer.
