    Hi, that filler might mask the gap, but to my mind it appears to possibly be an expansion crack or stress fracture of some type, so the filler is likely to delaminate and either fall out or come loose over time. You might try use some super-glue and see if you can get it to sit flat first and limit any movement, that might help the filler to bond better. 👍️

    Thanks for the info.

    It's a cheap door probably 20 years + old.

    Unfortunately it's a dark colour and is southerly facing so it gets baked by the sun.

    I was in Brooks and surprised to find a dark brown Tech7. Perfect colour. It's is elastic to 350 and good to 90 degrees. I'm going to risk it ...

    If it doesn't work out I might cover that area with a house door number ;-) Just thought of that now

    Will post back how I get on

    Thanks again

    The sun explains it. Tec7 filler or adhesive? If it's a filler then I'd definitely do a spot of super-gluing beforehand.

    Does it say on the tube of Tec7 that its suitable for Pvc? If not use Low Modulus silicone, it's not easily available but builders providers would stock it.

    Hi,

    Tech 7 site says ...

    1. Tec7 Sealant can be used with most building materials including PVC and replaces most other plastic glues

    I will do a spot test. It is my own door so if it isn't a 100% job it's OK.

    If it doesn't work right I will get a price of backing board and the house number on it to cover the crack

    To date every problem I've had in life has been solved with Tech7 money or Duct tape ! I've great faith in Tech 7
