One of the factors affecting the construction of the floor includes the climate, not only the temperature, but also the humidity.It is also a very important influencing factor. The temperature of the floor is too high or the quality of the floor and its appearance will change. As a result, the floor becomes white and blistering. Will it affect the construction progress of waterborne epoxy floor paint in rainy days? What impact does it have on construction? Let's take a look at how to apply waterborne epoxy floor paint on rainy days.
In rainy weather, the air pressure is usually low. At this time, when water-based epoxy floor paint is applied, many unhelpful substances are simply left, and these substances are not volatile. Therefore, it is necessary to open the appropriate doors and windows for construction and do indoor ventilation. Accelerating the undulation of indoor air can also ensure the health of the construction staff. In rainy weather, water-based epoxy floor paint should be prepared for the edges slowly, and an industrial-specific dehumidifier should be prepared compared with the ground floor construction requirements.
2.The moisture content in the air is the humidity, which can be measured with a hygrometer. Generally, the humidity of the water-based epoxy floor paint is better than 85%. The humidity is large in rainy days, which simply affects the curing of the coating. The appearance of epoxy floor paint is prone to whitening, which affects its application!
3.Second, the rainy weather has a low temperature and the waterborne epoxy floor paint needs to be used because it needs to be mixed. In this way, it is easy to form a situation where the main agent and the curing agent are not sufficiently mixed, thereby reducing the construction quality of the sunken floor. The rainy climate is because the air is relatively humid, the ground is boring and inadequate, and because of its special ingredients, waterborne epoxy floor paints can not comprehend water as well as concrete. Therefore, the water content on our ground In small conditions, it often does not meet the construction conditions.In this way, blind construction will cause future delamination on the ground and air bubbles can be questioned.
4.If the air is relatively moist, the ground will also be affected.If the water-based epoxy floor paint is directly applied on such a wet floor, it will simply cause the floor to warp, so you must ensure that the ground is dry and dry at the border of the wet and dry areas. Ability to apply interval treatment.
5. Suppose that because of the dark climate, there is no way to stereotype on the ground, and the machine may be used for drying. The more suitable construction climate for waterborne epoxy floor paint is proper wind, and the temperature is arranged at 20 ° C. Waterborne epoxy floor paint construction 2 ~ For 3 processes, we need to ensure that each process data is transparent and dull to implement the next process.
6, rainy construction, water-based epoxy floor paint is simply white. In this climate, the wall and the city on the ground survive water vapor, the information is not simple and boring, if the putty is not dry, the next step of construction will understand a series The coating film is wrong or even cracked. So make sure that each process data is boring before proceeding to the next layer. Or participate in the appropriate whitening water coordinator in the data to speed up the dryness of the coating.
To sum up, the rainy weather has some influence on the construction of waterborne epoxy floor paint, but we can still avoid some problems in this regard. Waterborne floor varnish waterborne epoxy floor coating is a two-component coating, which has good water resistance, oil resistance, acid resistance and alkali resistance, salt spray corrosion resistance and other chemical properties. Washability and environmental protection. It can meet the needs of modern industrial floors, and has advantages that solvent-based epoxy floor coatings do not have, such as Chongqing floor construction tools easy to clean, construction process and other characteristics. After the water-based floor paint is cured, there will be a small amount of water in the coating film, which can prevent the solvent-free epoxy floor paint from being too dense and the water vapor in the concrete cannot be removed, resulting in blisters, deformation, hollowing and even peeling. Membrane defects. Due to the curing characteristics of water-based epoxy floor coatings, the dried coating film has microporosity, which allows water vapor to penetrate. This releases the pressure of water vapor inside the concrete, protects the coating from damage, and protects the concrete.
