Dry Seal Elastic Glazing Sealant

A durable alternative to Linseed Oil Putty. Linseed oil putty is widely used for glazing windows and doors. The putty is inherently brittle and generally shrinks away from the glass. The breakdown of putty causes early break down of the paints and is mainly responsible for open joints and wood decay due to moisture ingress.

We use Window Care Dry Seal; as Dry Sela can help to prevent or reduce the on-set of wood decay on exterior joinery. The dry Seal is paintable with opaque and translucent wood finishes and is extremely effective against moisture ingress. This product is now being recommended by the majority of Architects and Maintenance surveyors.
