Some types of external wall insulation mortar construction points

1, impermeability crack plaster mortar must be applied before thermal insulation layer is sufficiently solidified. Usually by the hand does not move under the surface of the situation. The day before construction watering moist. About an hour before plastering and then poured water again. When crack mortar construction, with iron trowel and then smoothed with a plastic trowel rub flat nap.
 
2, wall insulation mortar construction should be divided over the conduct. Each time a thickness of not more than 8 ~ 10mm, should be applied compaction level, until the initial setting of watering wet insulation mortar, to prepare for the next pass plastering. When layered plaster interval is generally more than a day, until the surface thickness of red bars, the first bar with a large Calibrating, then iron trowel smooth force.
 
3, impermeability crack mortar mix should vary with the use of parking time should be about three hours, this ash fall can not be used. After the initial setting should be water conservation, curing time should be about seven days.

4, concrete walls: with the amount of caustic soda water to remove surface oil, then rinse dry. After watering wet smear interface treatment agent, can be applied to law or nap law.
 
5, wall insulation layer conservation until the initial setting before watering moist. Watering interval is determined according to a dry environment, keep the surface whitening phenomenon does not occur, water conservation days
 
6, while the external wall insulation construction window and door openings should be in the perimeter insulation mortar exterior wall plaster, in the eaves, bay windows, window lintel, canopy, balcony, part of the top surface of the top pressure and prominent wall with cement mortar to make a slope, below drip line should be done.

7, brick wall: the wall residual mortar, dirt, dust, clean, humid day before plastering watering. Plaster one hour before watering once again, to meet the construction requirements.
