At what temperature is putty powder suitable for the weather and temperature requirements of construction putty scraping?

When decorating the wall, blow putty to make the floor below more flat. However, the putty powder construction needs temperature and humidity, and the external temperature will affect the putty construction effect. Then, at what temperature is putty powder suitable for construction? What is the suitable temperature for putty construction? What is the minimum construction temperature requirement for putty scraping? Let's take a look together.

What temperature is putty powder suitable for construction?

The construction environment of putty powder has an influence on the construction quality of putty, so what temperature is suitable for scraping putty? The construction environment has always been a very important factor. If the ambient temperature is too low, it will easily affect the dissolution of organic additives in putty. If the additives are not fully dissolved or the dissolution speed is too slow, it will affect the coating quality and construction performance of putty after batch scraping. Of course, the environment is too hot and dry, so 5℃-35℃ is suitable for putty construction.

Weather and temperature requirements for putty scraping

The putty construction environment is that the temperature is within 5-35℃, the air humidity is less than 85%, and the humidity cannot be less than 10%.

Matters needing attention in putty construction:

1. Batch of putty shall not be too thin or too thick. If it is too thin, the putty layer will easily lose water too quickly, which will lead to putty pulverization and ultimately affect the painting effect. The thicker the putty layer is scraped, the greater its drying shrinkage strength and the easier it is to crack. Therefore, the batch scraping thickness of a single putty is preferably between 0.5 mm-1mm.

2, before blowing be bored with child, metope to clean, no floating ash.

As the basis of scraping putty, if there is floating ash or loose wall surface, the putty layer can not form a firm bond with the wall surface, which is easy to cause problems such as displacement and falling off of the putty layer. The putty layer can not only level the wall, but also serve as a "bridge" between the wall and the paint. If the putty can't be closely attached to the wall, it will shrink and expand under the external force caused by temperature change, humidity change and other factors, resulting in cracking of the putty layer.

3. Put the putty for a few minutes after stirring, and then stir for later use.

After stirring, let it stand for a period of time to provide sufficient dissolution time for the components in the putty, so as to ensure the construction performance and later film-forming quality of the putty and avoid the waste of additives. Putty should be used within half an hour after being mixed into paste, so as to avoid the deterioration of putty affecting the construction effect.

The above is about what temperature putty powder is suitable for construction and the weather temperature requirements for scraping putty. Blowing putty requires air temperature and humidity, and the temperature should not be lower than 5℃, so as not to affect the construction quality.
