Installation
- Ensure the aperture for the pipe size has adequate annular gap for UniWrap® to be installed. Insert the pipe into the aperture.
- 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.
- 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.
- Place additional layer(s) of wrap around the pipe if required, depending on your pipe size.
- Secure again with adhesive tape.
- 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.
- 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.
- Maintain record of installation.
