Correct Installation of BBA Approved EXP 6 Expanding Foam Tape
Ensure Maximum Performance, Reduce Wastage & Eliminate Mistakes by Following These Steps.
You need to determine which size of EXP6 Tape you need by measuring the joint width and allowing for maximum predicted movement.
- Tape Measure
- Flat Bladed Instrument i.e. Trowel
Preparation of Surface
Joint surface should be clean from dust, sand, lose particles and any debris and obstructions.
EXP6 Expanding foam tape will expand faster when subjected to heat, equally it will take longer to expand in cold conditions, it should always be stored at normal “room temperatures”.
Using scissors remove the self adhesive leader strip, cut off and discard the deformed beginning of the tape, creating a square end (you should also repeat this process when you reach the end of the tape roll).
Peel back approximately 15cm of the release paper to expose the self adhesive side of the foam tape. When installing EXP6 into the joint fix the self adhesive side to the smoothest surface (e.g. the window frame) using a palette knife / trowel of any flat blade tool. Ensure you do not stretch the tape. Continue to unwind the tape from the roll peeling away the release liner as you do so until the joint is filled.
You must oversize the length of the tape in the joint by 1cm per meter to allow for any accidental stretching and also to ensure any blind ends are sealed correctly. Instantly apply the tape into the joint ensuring the visible edge of the tape is set back into the joint by at least 1 to 2mm.
Once the tape is installed it will expand to fill the joint (as previously stated the expansion rate of the expanding foam tape is dependant on temperature) this expansion makes the expanding foam tape self supporting. Any unevenness along the joint will be automatically be accommodated by the tapea s it self expands.
Do not unwind the tape until you are installing it.
Secure any partially used rolls tightly to prevent any unused expanding foam tape from expanding prior to installation.
