Method for external insulation construction of polystyrene board thin plastered surface in cold and windy area

A method for external insulation construction of a polystyrene board thin plastered surface in a cold and windy area is characterized by comprising the steps of construction preparation, base surface processing, designing, line snapping, fire barrier arrangement, surface dressing and polishing, sand plastering of a bottom layer, mortar laying of gridding cloth, plastered surface mortar pouring and on-site testing and detection, 1:3 cement mortar is adopted for plastering and leveling after interface processing is conducted on a base layer, a wall is designed and divided through line snapping, an EPS board is attached with specific adhesive glue and fixed to the wall of the base layer under the assistance of an anchor bolt, detail enhancement is conducted, anti-crack mortar composite glass fiber gridding cloth is used as a protecting layer, and coating or decoration mortar serves as an external layer. Aiming at the special weather of the cold and windy area, by means of bonding between the EPS board and the wall, combination of the external layer and joint processing technology improvement, construction quality is guaranteed, a heat insulation material layer and a thin plastered surface layer are combined firmly and stably, integrality is high, the heat insulation performance of the exterior wall is improved, building materials are saved, and construction time is shortened.
