Features & Benefits
- Economic sealant for horizontal and inclined joints up to 1 in 20
- Resists dirt and ingress of grit associated with trafficked pavements
- Good adhesion to concrete and asphalt surfaces
- For sealing movement and construction joints in pavements, floor slabs, water retaining and water excluding structures
- Complies with BS 2499 :1993
Application Notes
- Suitable for joints up to 30 mm wide in trafficked surfaces, but joints up to 65 mm wide can be sealed with Nitoseal hot-pour where the joints are horizontal and are not subject to trafficking. The depth of Nitoseal hot-pour compounds should not exceed 50 mm and for most normal uses, 25 mm is recommended
- All joints which extend below the high water table level should contain a waterstop in addition to the hot-pour seal
- Use Fosroc Primer B2 on concrete, stone and brick paving. Allow primer to become touch dry before sealing, normally 1 to 4 hours. Metal surfaces do not require priming but should be warmed to ensure satisfactory adhesion. Ferrous metals should be treated with an anti-corrosion primer
- The use of a heating vessel with an oil jacket and fitted with stirrer and thermometer is essential
- Cut the compound into small pieces, melt a few pieces then gradually add more pieces to the molten material, stirring continuously. Heat until the compound reaches correct pouring temperature (175°C to 185°C)
- Extra care should be taken in cold weather. The cold surfaces of the joints may cause rapid chilling of the compound. To help compensate for this, the compound should be poured at the top limit of the pouring temperature range. Frost may give concrete a deceptively dry appearance
- Compound which has been heated and then allowed to cool below 95°C must be scrapped. It must not be remelted for use. In expansion joints, Nitoseal hot-pour should be poured to a level 3 to 5 mm below the traffic surface to allow for upward displacement when the joints close
- Equipment should be emptied immediately after use
Limitations
- Does not comply with the fuel resistant requirements of BS 2499 :1993 and should not be used in airfield hardstandings, cargo handling areas, garage forecourts or other paved areas subject to fuel and oil spillage. For these applications Colpor 200PF should be used
- Softens when heated and should not be used in floors with under-floor heating or in areas where it would be subjected to heat from factory plant or steam cleaning operations
- Must be stacked flat not more than nine high and covered if stored outside
- Heating of compound should be carried out in well ventilated areas
