Ethafoam
Closed cell profile used to pre-fill joints or cracks to be sealed
Ethafoam is a preformed plastic cord in closed polyethylene foam, to pre-fill joints or interstices which will be sealed with elastomeric products.
Applications
Ethafoam is used as pre-filling for expansion joints, construction joints, static joints, or for any other crack or crevice which will be filled with Kimia sealants. It is possibile to cut it with scissors or cutters and follows the pattern and movement and joints even with sharp edges and corners.
Application
Use the Ethafoam cord of a proper diameter depending on the joint width to be sealed. We recommend using an Ethafoam cord diameter of 1.2 ÷ 1.5 times greater than the maximum joint width. If the limited depth of the joint does not allow the introduction of the proper size of Ethafoam cord, we recommend cutting it with a sharp blade to obtain a semicircular cord; alternatively, it is possible to pair with adhesive tape, two Ethafoam threads smaller in diameter than the theoretical (for example: two cords Ø 10 mm coupled, instead of a rope Ø 20 mm). The Ethafoam cord can also be deformed with a simple finger pressure. Push the Ethafoam cord into the joint at a depth that will meet the exact width / depth ratio of the elastic or plastic sealants (see technical specifications). The cord Ethafoam is self-sustaining within the walls of the joint, by simple lateral friction. After laying the Ethafoam cord continue to seal the joint with a suitable sealer.
