Rain resistant IMMEDIATELY after application, our SX Siroflex Rainproof Exterior Caulk is a high-quality acrylic sealant which is perfect for use outdoors. After application it forms a soft flexible rubber seal which stops water penetrating.

Our caulk can be used for sealing and filling gaps and cracks where movement can occur and is almost odourless, non-corrosive towards metals and can be used without a primer; even on damp surfaces!
