Rated 4 out of 5 by from Sealing Outside Joints Needed a sealant that would dry slowly to allow some movement to line up the joints in a timber outdoor sign and allow painting over when dry.

Rated 5 out of 5 by from Worth the money We had a leak around the patio doors, and when I dug out the old silicone it clearly hadn't bonded to anything properly. This stuff is incredibly sticky and quite thick, making it hard work to get out of the gun but it's worth it. It might be six times the price of the cheap stuff, but it's all I'll use now.

Can Dows 785 be used for bedding toilet pan onto a ceramic tile floor.

Outside toilet was originally bedded into concrete onto a concrete floor. New toilet going onto ceramic tiles. Can Dows 785 be used to bed in toilet pan before screwing down?
Asked by: FrankOxford

Would this be suitable to seal the external panels on a static caravan?

Asked by: KTaylor

How do I open it?

There is no hole that I can see for the caulking stuff to come out at, and I can find nothing there to provide a way for opening it to be able to use it?
Asked by: OldWoman

Ok for boat use? Is it affected by salt water?

Asked by: Cocat2517
