Shelf life: 9 months in original unopened packaging at temperatures of +5°C to +25°C.

Skinning time: Skin forms after approximately 30 minutes.

Working time: Approximately 30 minutes depending on conditions.


Joint design: Please consult the Technical Information Sheet entitled ‘Joint design for cartridge based products’ prior to application.

Surface preparation: All surfaces must be clean, dry and free from frost, grease and loose materials. Apply primer if required. Install bond breaker to prevent bond at base of joint where necessary. Most substrates only require priming if testing indicates a need or where sealant will be subjected to water immersion after cure. Cut the top of the screw thread off the cartridge and screw on the nozzle. Cut nozzle to correct diameter for joint size. Apply using a skeleton or powered gun into the joint ensuring good contact with surfaces.In deep joints, the use of Hodgson Backing Rod is essential to ensure good joint formation. In situations where an especially neat finish is required, use masking tape to cover the face edges of the joint and remove immediately once tooling has been completed.

Tooling: Tool immediately after sealant has been applied within the working time for the product.
