Application Notes
- Joints should be designed so that joint changes do not exceed the 10% MAF of Nitoseal PU800
- It is recommended that joints in new concrete slabs are left to the final stages of construction when temperatures have stabilised and the initial shrinkage has taken place
- Where joints are less than 25 mm and are fully supported by a solid backing, minimum depth should be 10 mm to 15 mm
- Where a resilient filler provides the backing, the minimum depth should be 20mm. For wider joints a square section is preferable
- Where surface shall be subject to submersion or permanently damp, joints should be primed using Fosroc Primer MS2
- Fosroc Nitoseal PU800 should be mixed thoroughly using a slow speed drill (300 to 500 rpm) fitted with a Fosroc Sealant Mixing Paddle
- Immediately after mixing load the Nitoseal PU800 into a Fosroc “G” Gun using a follower plate
