Closed cell polyethylene joint sealant back-up cord
Fosroc Expancell
Description
Expancell polyethylene foam back-up cords have the ability
to perform several functions. They enable the correct width
to depth ratio of the sealing slot to be maintained and
provide a firm backing for the sealant to be tooled. This will
precipitate wetting of the sides of the joint during the sealant
application thus facilitating good adhesion.
