Primer & P5 moisture resistant T&G chipboard before I laying Aquapanel?

[Sam Firmin]

Hello, please can someone advise me before I mess up and waste loads of time and money!

Do I need to prime P5 moisture resistant T&G chipboard before I lay Aquapanel? Also, do I have to then prime the Aquapanel before I lay the ceramic floor tiles? I will be using Mapei flexi quick set tile adhesive.

Thank you!

Priming the chipboard yes, priming the aquapanel is optional but it won't do it any harm if you use the correct primer.
