1.10FIELD CONDITIONS

Revise "Environmental Limitations for Epoxies" Paragraph below to limit work during cold conditions or to require use of enclosure and supplemental heat. Epoxies are very temperature sensitive and quickly assume the temperature of substrate to which they are applied.

  1. Environmental Limitations for Epoxies: Do not apply when air and substrate temperatures are outside limits permitted by manufacturer. During hot weather, cool epoxy components before mixing, store mixed products in shade, and cool unused mixed products to retard setting. Do not apply to wet substrates unless approved by manufacturer.
  2. Use only ClassA epoxies when substrate temperatures are below or are expected to go below 40 degF (5 degC) within eight hours.
  3. Use only ClassA or B epoxies when substrate temperatures are below or are expected to go below 60 degF (16 degC) within eight hours.
  4. Use only ClassC epoxies when substrate temperatures are above and are expected to stay above 60 degF (16 degC) for eight hours.

Retain one "Cold-Weather Requirements for Cementitious Materials" Paragraph below. Retain second if cold-weather work is allowed.

  1. Cold-Weather Requirements for Cementitious Materials: Do not apply unless concrete-surface and air temperatures are above 40 degF (5 degC) and will remain so for at least 48 hours after completion of Work.
  2. Cold-Weather Requirements for Cementitious Materials: Comply with the following procedures:
  3. When air temperature is below 40 degF (5 degC), heat patching-material ingredients and existing concrete to produce temperatures between 40 and 90 degF (5 and 32 degC).
  4. When mean daily air temperature is between 25 and 40 degF (minus 4 and plus 5 degC), cover completed Work with weather-resistant insulating blankets for 48 hours after repair or provide enclosure and heat to maintain temperatures above 32 degF (0 degC) within the enclosure for 48 hours after repair.
  5. When mean daily air temperature is below 25 degF (minus 4 degC), provide enclosure and heat to maintain temperatures above 32 degF (0 degC) within the enclosure for 48 hours after repair.
  6. Hot-Weather Requirements for Cementitious Materials: Protect repair work when temperature and humidity conditions produce excessive evaporation of water from patching materials. Provide artificial shade and wind breaks, and use cooled materials as required. Do not apply to substrates with temperatures of 90 degF (32 degC) and above.

Retain "Environmental Limitations for High-Molecular-Weight Methacrylate Sealers" Paragraph below if required. Temperature limit of 75 degF (24 degC) is typical for crack filling; 90 degF (32 degC) limit is typical for general application. Best results are achieved when substrates have been dry for at least 72 hours.

  1. Environmental Limitations for High-Molecular-Weight Methacrylate Sealers: Do not apply when concrete surface temperature is below 55 degF (13 degC) or above [75 degF (24 degC)] [90 degF (32 degC)] <Insert temperature>. Apply only to [dry substrates] [substrates that have been dry for at least 72 hours].
