About Teknos Teknoseal 4009 V Joint Sealer

Teknos Teknoseal 4009 V Joint Sealer is designed for construction joint protection.

Rounded construction and break joints are an attractive and effective feature of modern joinery design but can expose end grain on the machined rounded or scribed edges and create water traps on horizontal joints.

Teknos V joint sealer is a water-based flexible sealant which dries to a clear finish and provides a smooth surface for subsequent painting. It is suitable for opaque finishes and for translucent systems when applied after the base stain has dried.

It is not intended as a filler because it has no structural strength and should not be used to bridge gaps.

Teknos V Joint Sealer changes colour from white to clear as it dries and can be overcoated when completely colourless.
