The hot melt film can be applied at the temperature above-100℃, and the film is resistant to low temperature and not easy to freeze at negative temperature. Rain, snow, frost, fog, excessive atmospheric humidity and windy weather are not suitable for outdoor work, otherwise corresponding technical measures should be taken.

B, the requirements of the roof drainage slope flat roof drainage slope is 2% ~ 3%, when the slope is less than or equal to 2%, appropriate materials to find slope; When the slope is greater than 3%, the structure should be selected to find the slope. The longitudinal slopes of the gutter and eaves gutter shall not be less than 65438 0%, and the gap at the bottom of the gutter shall not exceed 200mm.
