Winter interior wall coating construction strategy
With the arrival of winter, the temperature dropped sharply and the wind was cold. However, there are still many owners who are busy decorating new homes to decorate old houses. In winter, the temperature is lower and the paint is dry, which brings a lot of inconvenience to the winter construction. It is the season of wall paint construction. If it is not possible to decorate, Xiaobian interviews professionals, and organizes them as follows: 1. Temperature requirement: It is recommended to carry out indoor temperature detection every time the brush is applied. In winter construction, it is necessary to ensure that the indoor temperature and wall temperature service are not lower than 5 °C (≤5 °C) during construction and within 24 hours after construction. When the outdoor temperature is lower than 0 °C, the indoor temperature is not lower than 8 °C before construction. If the room temperature of the room with heating or other heating methods should not be lower than 10 °C, the doors, windows, etc. should be closed before construction can be carried out (if the sealing is not good, it will cause cracks in the door, window or wind receiving part). 2, humidity requirements: indoor temperature must be guaranteed to be 85% before construction (≤ 85%). If there is heating or other heating equipment in the northern part of the room, you can take appropriate measures to control the indoor humidity. It is not appropriate to make the indoor humidity too dry (the indoor paint will crack due to too fast drying). 3, several layers of the wall: several layers of the wall must be able to achieve sufficient maintenance time, requiring winter maintenance for more than 4 weeks. Achieve a water content of ≤ 10%, pH <10. Avoid watermarks, blistering, alkali return and other ills. 4. Putty powder: When selecting the putty powder, it should meet the requirements of JC/T3049 “Building Interior Putty†and the standard, mainly the adhesion is good, has sufficient strength, is not loose, and has low alkalinity (pH less than 10). When batching putty, it is necessary to control the thickness of the batch scraping. It should not be thickly batched. Each time the putty should be scraped after the putty is dried one time. The putty layer must be dried before the bottom and topcoat construction can be carried out to avoid cracking, blistering and other diseases. 5, painting requirements: brushing, mixed coating, air spraying and airless spraying should be strictly in accordance with the construction ratio of construction, and should be fully stirred evenly, is not allowed to apply a single thick coating, it is strictly prohibited to over-water, avoid this The paint film cracks or falls off the powder. Keep sufficient drying time between the top coats to avoid sag and cracking. The recoating time generally requires more than 4 hours in winter and more than 2 hours in summer, and the rainy and humid weather is prolonged.
