  1. Ensure the aperture for the pipe size has adequate annular gap for UniWrap® to be installed. Insert the pipe into the aperture.
  2. Using the measurements on the side of UniWrap ® box, cut the UniWrap® to the correct length to wrap fully around the pipe. Check the UniWrap® Configuration table for the number of layers required, depending on your pipe size.
  3. Wrap the UniWrap® around the pipe, securing to itself via the double sided tape. For a simpler installation ensure the double sided tape does not stick the UniWrap® to the pipe itself.
  4. Place additional layer(s) of wrap around the pipe if required, depending on your pipe size.
  5. Secure again with adhesive tape.
  6. Push the UniWrap® into the annular gap between the wall opening and the pipe. Adjust the position of the wrap so that the edge is central within the wall or floor surface.
  7. Seal over the top of the annular gap with FireMastic – 300 Sealant to a depth of 5mm. Smooth the finish with a small trowel or by hand. FireMastic – 300 can be cleaned up with water.
  8. Maintain record of installation.
