Rated 5 out of 5 by from Excellent product Bought this to stick some trim around the lounge windows and improve while decorating. Bond's well excellent finish. Like it says on the instuctions it does give off an odour for a couple of days as all silicon sealants do.

Metal roofing sheets

Hello, can I use this to seal gaps in corrugated metal roofing sheets on south facing roof? We have water ingress and conscious that the roof sheets could get extremely hot in summer and very cold in winter...
Asked by: Bovrilelles
I would recommend Dowsil 791, a neutral-cure silicone with good weathering resistance. It will cure to form a flexible and durable water-tight seal. This product would also be able to accomodate the temperature variations you have described.

Can I use this for covering screws nails on socket board?

Asked by: Shwe
For best adhesion to screws and PVC we would recommend using the Dow 791 or Dow 799 silicone.
