Five problems that need to be paid attention to when water -based paint construction needs to be paid attention to
Theoretically, the construction of water -based paint has no special requirements for the environment. As long as the environmental temperature is higher than 5 ° C, and the air humidity is below 80%. Excessive air humidity or low environmental temperature can be regarded as harsh conditions for water -based paint construction. It may cause poor painting effect during construction, so you need to pay special attention to the following matters.
(1) Pay attention to temperature increase and humidity and humidity
When the temperature of the construction site is too low, the heater can be used to increase the indoor temperature and accelerate the drying speed of the paint film; if the humidity of the construction site is too high, the humidifier can be used to reduce the indoor humidity. Ensure that the construction place will reach a suitable environment and then formally construct.
(2) Pay attention to thin coating construction
Construction may occur in a harsh environment that may cause bubbles, flowing or difficult to dry. Therefore, it is necessary to avoid thick coating during construction. Thin coating can speed up drying, thereby reducing the chance of problems.
(3) Pay attention to construction time
Under normal circumstances, the temperature and humidity at night are worse than during the day, so you should try to avoid construction as much as possible in the evening. Do a good job of insulation in the room when receiving the work. Follow the window. Opening the window can penetrate the outdoor humidity into the room and cause paint to cause paint. The emergence of the disease.
(4) Pay attention to doors and windows base materials
The doors and windows are relatively close to outdoor, and it is easily affected by the low temperature and high humidity of outdoor. The drying of the paint film will be more likely to have problems. Therefore, it is necessary to ensure the construction of this area and operate according to the above 3 points.
(5) Repair and re -construction
Generally speaking, in this harsh environment, the phenomenon of white paint and cracking of paint is prone to. If you still can’t repair it well, you should confirm that the paint film is dry and then polished.
In order to answer your doubts, the above is what we have organized about water based spray paint, hope it can help you.
