Product Details

Product Application:

Design requirements

The constructive prerequisites of the joint must be according to the IVD leaflet Nr.1. The joint width must be calculated so that the cumulative motion of the joint is not higher than suitable for the sealing material. In areas where the joints will be subjected to vehicular traffic, joint edges must be prepared for application by saw-cutting/milling. The joint should be filled to just below the saw-cut (chamfers should not be filled). For high water pressure load, e.g. in sewage and waste water treatment plants, an additional stable back filling should be installed below the backer rod (e.g. sand filling and /or Styrodur-strips).

Mixing Instructions

INDUFLEX-PUis delivered ready-to-use in 600 ml sausage packs, and is applied with a suitable applicator gun. Using a suitable smoothing tool press the dispensed joint material into the joint flanks and back filling profile. When required the joint surface can be smoothed, within the working time, with a smoothing wood or soft brush by using smoothing liquid.
