Marmox Multiboard - Priming

[Casper]

Can anyone advise me on whether I should prime marmox multiboard with BAL SBR before tiling using BAL Single Part Flexible adhesive or can I tile straight onto the boards.

Thanks

No priming needed. Tile straight onto it. If in a wet area though, the joints need taping if you haven't done it already.

Thanks Paul.
