What is the recommended way to stick a 2cm deck pad corner (which has become unstuck) back onto the board?
Bunnings - Sikaflex Contact Adhesive
May not come off again however.
I've had success with auto window sealant.
You need to use the M/S Polymer glues (Modified Silane). All brands have at least one in their line.
For instance UHU Max Repair, Pattex 100%, SADER Mega Strong...
For a (partial) list see the "Universelle Produkte" section of www.wikidorf.de/reintechnisch/Inhalt/MSPolymerKlebstoffe
The different variants differ by their color, speed of curing, additives...
This is a new generation of glues: extra strong, but stay somewhat supple, and does not damage the board (no solvents) so removable. And my pads never un-glued again.
- you only need to apply to the pad, no need to apply on the board (no solvent)
- they use moisture to harden, so it is not a problem is the board is a bit wet
- put the glue, press the pad in place and keep pressure (put weights such as water bottles on it). It should begin to harden after 5 minutes (so you can reposition the pad in the first minutes) and ready to use after 12 hours
Re-glue the pad as soon as delamination appears. The more you wait the more the pad risks stretching and losing its shape, or even tear.
