Cleaner, more reliable seals - thanks to flexible EPDM foam
EPDM material offers good flexibility and heat resistance, allowing the foam to compress into irregular joint shapes while resisting common environmental stresses. The foam acts as a backing that supports a uniform sealant bead.
A firm backing prevents sealant from sinking or overfilling, producing neater, more durable seals that resist air and water infiltration.
Quick prep and installation - with 14 mm / 9/16 inch diameter and 2 m length
The roll arrives as a continuous length that can be cut to size and pushed into joints, with guidance to choose a diameter slightly larger than the gap for optimal performance. Standard scissors or cutting tools are sufficient for trimming.
Speeds up joint preparation for tasks like floorboard gaps and pipe seals, letting multiple repairs be completed from a single roll.
Versatile uses across home and workshop - thanks to lightweight, easy-to-cut foam
Lightweight EPDM is simple to handle and can be applied in a range of settings listed in the manufacturer notes, from construction and plumbing to automotive and craft projects. The material is suitable for repeated cutting and shaping.
Useful for preparing joints before caulking, filling gaps prior to mixing and filling, and a variety of DIY and craft tasks where a flexible backing is needed.
