Hot weather conditions
Following the below recommendations will help offset the effects of hot weather conditions and will result in the repair material having the desired characteristics.
- Work in the shade, if possible. Apply early in the morning and late in the evenings to avoid direct sun. Protect the job from wind, if necessary.
- Keep the repair material at a 70-75° F temperature. Keep the repair material in the shade, out of the sun before mixing.
- Use cold water to cool off surfaces where material is to be applied to get those surfaces as close as possible to the temperature of the repair mortar.
- Chill the mixing liquid, if needed. Use ice water, if necessary and appropriate.
- Mix the repair mortar as close to the repair area as possible and place repair material immediately. Keep the time of mixing, placing and finishing to a minimum. Do not over finish the material.
- Protect the material from rapid surface drying and beginning curing after finishing.
- Refer to Hot Weather Concreting in ACI Manual of Concrete Practice for more detailed information.
