Application Notes
- Machine Grade: Mixing is carried out through a metered mixing machine (30L or 400L pack)
- The mixed product may be poured directly from the tin into horizontal joints, or for application to horizontal joints less than 15 mm wide may be loaded into a Fosroc ‘G’ Gun for application
- When necessary, clean equipment with Fosroc Equipment Cleaner; ensure any mixed material is cleaned immediately after use. Cured material can only be removed mechanically
- Prime concrete joint faces with Fosroc Primer 7E
- Coverage dependant on joint size. Refer to "Guide to sealant qualities" in the Product Data Sheet for rates
Limitations
- Machine Grade product cures very rapidly. Mixed material should not be left in the machine hose or lance for >5 mins at 20°C, or >3 mins at 40°C, as material may become difficult to extrude as it approaches its mixed gel time
- Apply at substrate temperatures of minimum 5°C and rising. Material temperature should be in the range 15-40°C
- Do not apply direct heat to product
- Product is not compatible with bituminous surfaces
- Where product could come into contact with pavement asphalt, or when sealing trafficked joints >50mm wide at the time of installation please contact 0113 2455450 (option 2) or send a message to [email protected]
- For the sealing of industrial floor joints, higher modulus sealants such as Nitoseal MS300 or Nitoseal PU800 are recommended
