1、基層處理

1. Basic treatment

①基層清理：清除干凈、灑水潤濕。其中：混凝土表面潤濕后涂刷1：1水泥砂漿(加適量膠粘劑);加氣混凝土應(yīng)在濕潤后，抹強(qiáng)度不小于M5的水泥混合砂漿。

① Base cleaning: clean and wet with water. Among them: 1:1 cement mortar (with appropriate amount of adhesive) shall be painted on the surface of concrete after wetting; cement mixed mortar with strength not less than M5 shall be painted on aerated concrete after wetting.

②加強(qiáng)措施：當(dāng)抹灰總厚度大于或等于35mm時，應(yīng)采取加強(qiáng)措施。

② Strengthening measures: when the total thickness of plastering is greater than or equal to 35mm, strengthening measures shall be taken.

③細(xì)部處理：室內(nèi)墻面、柱面和門洞口的陽角做法，設(shè)計(jì)無要求時，應(yīng)采用1：2水泥砂漿做暗護(hù)角，其高度不應(yīng)低于2m，每側(cè)寬度不應(yīng)小于50mm.

③ Detail treatment: for the external corners of indoor walls, columns and door openings, 1:2 cement mortar shall be used as concealed corner protection when there is no design requirement, and its height shall not be less than 2m, and the width of each side shall not be less than 50mm

2、分層抹灰

2. Layered plastering

分為底層、中層及面層。其中，水泥砂漿不得抹在石灰砂漿層上;罩面石膏灰不得抹在水泥砂漿層上。

It is divided into bottom layer, middle layer and surface layer. Among them, the cement mortar shall not be plastered on the lime mortar layer; the overlay gypsum shall not be plastered on the cement mortar layer.

3、控制厚度

3. Control thickness

通常抹灰構(gòu)造各層厚度宜為5～7mm，抹石灰砂漿和水泥混合砂漿時宜為7～9mm.當(dāng)設(shè)計(jì)無要求時，抹灰層的平均總厚度：內(nèi)墻(普通20mm，25)，外墻(20)，石墻(35)。

Generally, the thickness of each layer of plastering structure should be 5-7mm, and that of lime mortar and cement mixed mortar should be 7-9mm. When there is no design requirement, the average total thickness of plastering layer is: internal wall (common 20mm, 25), external wall (20), stone wall (35).

4、設(shè)置分格縫

4. Setting the dividing seam

5、保護(hù)成品

5. Protection of finished products

各種砂漿抹灰層，在凝結(jié)前應(yīng)防止快干、水沖、撞擊、振動和受凍。水泥砂漿抹灰層應(yīng)在濕潤條件下養(yǎng)護(hù)，一般應(yīng)在抹灰24h后進(jìn)行養(yǎng)護(hù)

All kinds of mortar plastering layers shall be protected from quick drying, water flushing, impact, vibration and freezing before setting. The cement mortar plastering layer should be cured under wet conditions, generally after 24 hours of plastering
