3M 4412N Extreme Sealing Tape provides a leak solution for roofing at a swimming pool complex in Auckland, New Zealand. The old sealant between the steel roof sheets had failed, causing water leaks. Removing and replacing the old sealant would have been a lengthy and costly process. Instead, contractors were able to quickly seal the leaks by scuffing the steel, cleaning it, and applying the 3M tape over the old sealant in a matter of days. The tough yet flexible backing of the 3M tape makes it suitable for long-term outdoor use in sealing existing seams and preventing leaks.

The roof of a swimming pool complex on Auckland’s North Shore, is covered with long run
roofing iron with a seam sealer between the steel sheets to ensure water tightness.
Over time, the sealer had failed and rain water was leaking through the roof and was dripping
onto patrons inside. The management were faced with the problem of removing all the old
sealer and replacing it with a more appropriate product. This would have involved weeks of work
and the labour cost would have been prohibitive. Instead, they chose to use 3M 4412N Extreme
Sealing Tape to make the complex weather tight.
This tape is a soft, 2mm thick pressure sensitive acrylic adhesive tape designed for difficult
sealing applications. The backing of the tape is a very tough, yet flexible ionomer that has
excellent abrasion and UV resistance making it particularly suitable for long term outdoor use in
sealing existing seams and penetrations.
The contractors at the swimming pool complex only needed to scuff and clean the roofing steel
on either side of the join and then lay the tape in place over the top of the old sealer.
A quick roll down to ensure maximum adhesion completed the installation in a few days rather
than the weeks required to replace the old sealant.
