1. Causes of cracks in putty walls.
Improper treatment of the base layer: Before the construction of putty, the treatment of the base layer is crucial. If there are impurities such as oil and dust in the base layer, or the flatness of the wall is insufficient, it may lead to poor bonding between the putty and the base layer, resulting in cracks.
Putty quality problem: The quality of putty itself is also an important reason for cracks. If the putty powder is of poor quality, such as containing too many impurities, insufficient adhesion, etc., it may lead to cracking of the putty layer.
Construction skills: The construction skills when scraping putty are also related to the quality of the wall. The putty batch scraping is too thick, the batch scraping is uneven, and the next operation is carried out before it is fully dried, etc., which may lead to cracking of the putty layer.
Environmental factors: Environmental factors such as temperature changes, humidity changes, etc., may also cause putty wall cracking. For example, when the temperature is high in summer, the moisture of the putty layer evaporates rapidly, which is easy to produce shrinkage cracks; In winter, when the temperature is low, the putty layer is susceptible to freezing, and cracks will also occur.
2. How to prevent putty wall cracks.
Do a good job in the treatment of the base layer: ensure that the base layer is clean and flat, free of impurities such as oil and dust, and improve the adhesion between the putty and the base layer.
Choose high-quality putty: buy regular brands of putty powder with reliable quality, and avoid using inferior products.
Master the correct construction skills: follow the principle of "thin batch many times" to avoid excessive scraping of putty batch; Make sure that the putty scraped in each batch is fully dry before proceeding to the next step.
Pay attention to environmental factors: try to avoid construction in extreme environments such as high temperature, low temperature, high humidity, etc., to reduce the impact of environmental factors on the putty layer.
Cracks in putty walls are not inevitable after scraping, as long as we understand the causes of cracks and take corresponding preventive measures, we can effectively avoid cracks. From base treatment, putty selection, construction techniques to environmental factors, every link is related to the aesthetics and durability of the wall.
