the last photo looks like he has overboarded the dots of adhesive.
It’s all getting a bit confusing as to how many layers you have. Whatever happens, you can’t just screw a bit of board onto dots of adhesive and hope for the best. Shortsighted thinking. There is no quick fix to this. No magic board. Just logic and manufacturers instructions.
I’ve also lost count of how many layers I have. The full situation is just a nightmare just wanted it fixed and have what we paid for especially with having kids in the house in the run up to Christmas. Some people don’t have a heart it seems. Thank you for taking the time to reply I genuinely do appreciate each and every bit of help I am getting.
