 1、外墙柔性耐水腻子一般是膏状或者是双组分产品,是由高分子聚合物乳液、助剂盒粉料等制成的具有一定柔韧性和耐水性的腻子。外墙柔性耐水腻子不但有找平基层作用,还能防止墙面细微裂纹盒裂缝(不包括结构裂缝)的产生。 

2、外墙柔性腻子施工前要保证基层坚实、干燥、平整、清洁、无浮灰、无油迹。新墙一般需保养28d左右。腻子须均匀无结块。 

3、在批刮腻子前须先涂一层弹性底涂封底,起防水透气作用。 

4、外墙柔性耐水腻子一般需要刮涂2—3遍,在刮下一遍时要保证上一道腻子已干,不影响刮涂。严禁在腻子涂膜未干时进行施工。 

5、 因为外墙柔性耐水腻子中有弹性乳液,有最低成膜温度限制,因此应在被涂物表面及环境温度高于5℃、相对湿度低于85%的条件下施工。

 

 

1, the outer wall flexible water-resistant putty is generally a paste or a two-component product, is made of polymer polymer emulsion, aid box powder, etc. with a certain flexibility and water resistance putty. The flexible water-resistant putty on the outer wall not only has the effect of leveling the base, but also prevents the formation of cracks in the wall cracks(excluding structural cracks).
2, the outer wall flexible putty before construction to ensure that the base solid, dry, flat, clean, no floating ash, no traces of oil. The new wall generally needs to be maintained around 28d. The putty must be evenly unlumped.
3, in the batch scraping putty must be coated with a layer of elastic bottom coated bottom, waterproof breathable effect。
4, the external wall flexible water-resistant putty generally needs to scratch 3 times, in scraping down to ensure that a putty is dry, does not affect scraping。 It is strictly forbidden to carry out construction when the putty coating is not dry。
5, because the external wall flexible water-resistant putty has elastic emulsion, there is a minimum film temperature limit, so the surface and ambient temperature of the coating should be higher than 5 °C, the relative humidity is less than 85 %。
