Usage

Sika® PEF Rod is pushed into joint gaps to form a uniform and firm base for controlling the depth of gun applied elastomeric sealants such as Sikaflex. Sika® PEF Rod can be used for forming the base of vertical and horizontal joints in the following applications:
  • Joints between precast concrete panels
  • Saw cut joints in concrete floors
  • Peripheral joints around aluminium and timber windows
  • Around penetrations through walls and floors
  • Expansion joints between bricks and masonry
  • Can also be used for draught-proofing and dust-proofing of joints in situations where no other form of sealing is required
