Applications & Uses

Compatible Substrates & Surfaces
Applications
  • QM 85 is designed specifically for industrial floor applications which receive heavy vehicle traffic such as forklifts or steel wheeled carts. Use QM 85 to fill interior floor joints on horizontal concrete. It is slightly flexible allowing small slab movement yet rigid enough to protect vertical joint edges from damages by extreme loading from heavy wheeled equipment. Excellent choice for: Industrial warehouse floors, big box stores, cold storage facilitites, airport hangers, food processing facilities and manufacturing plants.
  • Joints must be clean, sound, and dry. Remove all bond breakers such as dust, grease, curing compounds, waxes, foreign particles and disintegrated materials. For bulk mixing, use a one to one ratio pump. Only component "B" side needs to be stirred before being loaded into pump. Do not allow material to reside in static mixing head or nozzle for more than 45 seconds or nozzle blockage may result.

Directions for Use

  • Clean control joint removing all dirt, oil, dust or other debris.
  • Ensure area is dry prior to application.
  • For bulk mixing, use a 1 to 1 ratio pump.
  • Only component “B” must be stirred before loading into pump.
  • Excess cured material may be stripped or peeled from repair area as well as plastic tools and containers.

Safety & Health

Safety & Health

Limitations

QM 85 is not designed to seal cracks under hydrostatic pressure, however it is a vapor barrier after cure. The minimum age of concrete must be at least 28 days, but it is highly recommended to wait as long as possible before installation to allow for maximum shrinkage of concrete slabs. QM 85 is limited in its elongation properties and is not designed to be used in moving cracks. Exposure to ultraviolet light may cause slight discoloration, however the physical properties are unaffected.

Clean Up

Cured QM 85 is inert and may be disposed of without restrictions. Excess liquid ‘A’ and ‘B’ material should be mixed together and allowed to cure and then disposed. Cured materials may be stripped or peeled from plastic tools and containers.

Safety and Handling

All personnel should read and understand product Material Safety Data Sheets provided. Long sleeved overall or disposable overalls, rubber gloves, splash shields, rubber or leather boots should be worn. Do not use ear high heat or open flame. Do not take internally. Keep out of the reach of children.

First Aid

Remove any contaminated clothing. For eye contact, flush immediately with plenty of water for at least 15 minutes; contact physician immediately. For respiratory problems, remove person to fresh air. For skin contact, remove epoxy immediately with a dry cloth or paper towel. Wash area of contact thoroughly with soap and water. Solvents should not be used because they carry the irritant into the skin. Wash contaminated clothing prior to re- use. Cured products are innocuous.
