In some cases double sided tape may be required to hold a panel in place while the adhesive sets. This can be required if you are not installing onto a bench and the panel needs to hold in place unsupported.
The product we would recommend using is 3M -Scotch Heavy Duty – Double sided Tape. 25mm wide. Available at Bunnings and Mitre 10.
You will have to determine how much of this you apply to the rear of the panel – which is dependent on how large the panel is. Panel weight is 7 kg per square meter.
Warning— once you have secured the panel with this tape it will be difficult to move so ensure you are accurate with sticking to the wall
