Upvc Facia board to Window sealant ???

[utterlydiy]

I had Upvc Double glazed windows and Facia boards fitted some two years ago.

I want to replace the current sealant with new because it has discoloured badly against the white of the boards and windows.

Which would be the best exterior sealant to use with the Upvc boards and windows with long lasting whiteness and weathering.

Thanks

Basically I'm asking should I use a Silicone, Mastic or Acrylic based exterior sealant.

thanks

Use a low modulus, neutral cure silicone; the surface must be thoroughly cleaned befeore applying new sealer.

If it's only lasted 2 years, call the installation company back, they used either the wrong or cheap crap sealer.

Richard - do you really expect them to come back . About as much chance as a Dish fitter drilling a neat hole in face brickwork

Always worth a try, most of them offer a 10 year warranty even if it only kicks in once the company has gone bust; you never know your luck

From a plastics site they offer 'LMN Neutral Cure Silicone Sealant'

Any good or is there better.

Thanks again

It needs to be low modulus.
