DAFA joint backup/backstop

The joint backup/backstop serves as a secure backstop for building seals and is an excellent match with other building materials.

DAFA joint backstop is used for filling around interior door frames, along timber batten ceilings, under skirting boards, or behind plastic sealants. A joint backstop can also be used for sealing corrugated or other types of roofing panels. The PU material is not UV-resistant.
