  • Facilitates the mastic implementation
  • To position according to the necessary height of mastic

In accordance with relevant standards (French SNJF and ISO), the joint backing is a material that is laid to limit the depth of the sealant in the joint and to define the back profile of the joint. It stops the sealant from adhering to the three faces of the joint and helps to resist the pressures that occur when apply the sealant. The joint backing must not have any effects that will change the physical and chemical properties, and even the appearance, of the sealant. It can eventually serve as a barrier to separate the sealant for chemical attacks from the bottom side of the joint.

The joint backing is used as a permanent formwork when applying a sealant or any other finish. It is used to limit the depth of sealant that is applied. It is recommended for use with the following sealants: silicone, polyurethane, polysulphide, acrylic. Recommended by SNJF (French institute for the classification of plastic and elastomeric sealants) as air and water seal in construction, as well as a seal in formworks.

Grey closed-cell polyethylene foam. Available in diameters from 10 mm to 100 mm, supplied in coils or in length according the the diameter used.


Grey foam supplied in coils or lengths.

The load-bearing capacity is always indicated for a joint in its initial position. In case of opening movements, the load-bearing capacity significantly reduces and the product will thus be only adapted for a light pedestrian traffic. The indicated load-bearing capacities are based on pneumatic wheels vehicles with a contact surface of 200x200 mm.
