COLORTEX ANTIFROZEN additive should not be added directly to the dry mix, it is done during the mixing of concrete mortar with water. Considering the plasticizing effect, reduce the amount of water by 15-20% compared to usual. In negative temperatures, it is necessary to heat the base to +10°C, and the mortar to +25°С, to achieve maximum efficiency. To reduce the rapid loss of moisture and heat due to cooling, it is recommended to use high-quality and quick-setting cements. After finishing the work, it is recommended to cover the newly laid concrete mortar with waterproofing and heat-insulating materials: polyethylene film, foam board, and if possible, arrange additional heating. It is not recommended to use precast dry mortars in modified mortars, unless otherwise specified in their conditions of use.
