I was wondering if anyone knows what the lifespan of clear silicone sealant is when exposed to UV (i.e. south facing aspect)? I am thinking of ordinary builders stuff used externally here rather than anything special.
TIA,
Alex.
I believe the normal manufacturers' warranty is 10 years. Experience would suggest that this is rather conservative, to my knowledge no RTV silicone has failed in normal service since its invention about fifty years ago.

Thanks John...
Pretty resilient then.
FYI: unibond's site quotes 35 years, but I was not sure if this was for higher performance stuff.
Cheers,
Alex.
