Good morning Steve,
I can see that you had a telephone conversation with one of our senior technical advisors last week and an email was also sent to you, relaying the information that was discussed over the phone. There is no mention of you being advised to use staples in this information. The technical advisor has informed me that you would have been using levelling compound over the top of your boards. In this case, we would not be advising to use staples at all. If you would like to discuss further, please do not hesitate to contact us on 01268 567016 and choose option 2 for Technical Support or option 3 for Customer Services.
Kind regards,
Hayley
