Polyurethane Sealant - Windows and Doors - 300 ml - White is rated
Rated 1 out of
Terrible, moulds up and gets UV damaged quickly.
Caulked my exterior windows with this sealant 12-24 months ago. Any spots on the windows that see prolonged moisture have the sealant moulded up black. It also is fraying and becoming brittle from UV/water. Terrible as Urethane sealants are supposed to be the most resilient exterior caulks.
