Refitting plastic cover to upvc porch

[Longshanks]

Hi

Corner cover from porch front has come off. Tried to temporarily redux with superglue but no joy. Adhesive has obviously dried, so guess need to reapply. Can you suggest best product please. Ta

Clear LMN silicone.
Sand paper (to rough up/key surfaces) then clean/degrease (with white spirit or solvent cleaner) then stick it on

Thanks for helpful response. Searched, and the stuff doesn’t seem to be available in main DIY stores. Is that right?

Its everywhere. LMN stands for Low Modulus Neutral cure.
To be honest any good quality adhesive would do, Us window fitter use the above as it wont damage/eat into PVC but for just sticking on a cap pretty much anything would do it

Thanks. Think I must have looked at the ones described specifically as LMN.

Hi again

One last query. Got the sealant, but how should so apply? Assume a series of beads across surface?

Process

1. Apply as above
2. Sand as indicated
3. Clean with white spirit
4. Reapply cap
