If you want to keep an area free from water ingress, then it's best to use either a glazing sealant or a frame sealant. We stock an extensive range of both, which are available in both acrylic and silicon finishes. It's always absolutely vital that you use a frame sealant with good UV if you want to ensure your frames are resistant to both water and weather.
Most of the glazing and frame sealants we stock can be painted over, meaning they won't get in the way of you achieving a perfect finish. Usable with tools such as a sealant or caulking gun, you can rest assured that the sealants we stock won't let you down.
