[Construction] Flat coating construction process of elastic coating for exterior wall
Let the new cement on the wall mature for at least one month to reduce the alkalinity of the wall appropriately and make the wall dry. The moisture content of the wall must be less than 10%; if the ambient temperature is low, the wall is ready to dry The time has been extended accordingly.
The quality supervision department has taken action, and the public wall requires the use of water-resistant putty
Shandong Weihai Quality Supervision Station requires that from October 1, 2016, the stairwells and corridors of new residential construction projects need to be scraped on the walls of public parts on the ground
【Construction】Scrape putty in this way so that the wall will not be hollow and cracked
The putty layer is hollow and blistered, mainly due to the presence of gas between the base layer and the putty layer. There is a dense layer between the base layer and the putty layer.
