Dunlop PEF foam filler Rod

DUNLOP PEF foam filler (aka backing) rod is a flexible polyethylene foam cylinder that is pushed into gaps where there is a construction joint  ie wall/floor joins.  The join is then filled to level with a DUNLOP Silicone Sealant as a two-sided (join edges) bond sealant and “breaker” for waterproofing membranes at joins to allow for expansion/contraction at these surface junctions, predominantly where a change in surface direction takes place.

DUNLOP PEF foam filler rod is excellent for:

  • providing an un-bonded third surface for DUNLOP Neutral Cure Silicone at joins, prior to the application of wet area flooring in places like: bathrooms, kitchens, laundries
  • cost-effectively filling joins to prevent over-filling with DUNLOP Neutral Cure Silicone

In construction joins such as wall/floor joins; especially prior to the application of DUNLOP Neutral Cure Silicone in preperation for wet area flooring
