How long after applying latex paint can I open the window?

1. Generally speaking, three days to a week is enough.

2. To determine whether it is repaired, you can touch the wall with your hand to see if it is still damp.

What are the steps for applying latex paint on the wall

1. Comprehensive inspection. Check whether the cement wall in the rough house that needs to be painted is solid and flat. If the plaster layer on the wall is not strong enough or there are large cracks and holes, it is recommended to complain to the developer or property and ask them to redo it. If you want to repair individual holes by yourself, you can use plaster to fill them. Finished product protection. There will be dust when handling the wall, and it is inevitable that putty, paint or other glue will drip, so you must do a good job of protecting the finished decoration in the room in advance.

2. Preparation before scraping putty. Make sure the wall is solid and flat, clean the wall with a steel brush or other tools, make the cement wall as floating as possible, and without loose soil. Roll the concrete interface agent on the wall as evenly as possible, and wait for it to dry (usually more than 2 hours), then you can scrape the putty.

3. Scrape putty (please choose water-resistant putty). Before scraping putty, the flatness of the wall should be measured (with a measuring ruler of more than 2m) to determine the method of scraping putty. Generally, two layers of putty can be scraped on the wall to level it. If the flatness is extremely poor and the wall is seriously tilted, you can consider scraping the plaster first for leveling, and then scraping putty. Putty with poor flatness needs to be scraped several times in some parts. The interval between each layer of putty should be more than 2 hours (after the surface is dry).

4. Polishing putty. After the water-resistant putty is fully strengthened (5-7 days), it will become extremely solid. Polishing can be done at night, with a 200-watt or higher light bulb close to the wall for lighting, and checking the flatness while polishing. Polishing at this time will become extremely difficult. Therefore, it is recommended to start polishing the putty 1-2 days after scraping the putty.

1. How long does it take for latex paint to dry thoroughly?

Normally, at room temperature of 25 degrees, latex paint will solidify and dry within two hours. In winter, the temperature is relatively low, so it is necessary to extend the time accordingly. Normally, it will dry completely in about two days. The specific time depends on the temperature. If the latex paint is not completely dry, you cannot directly apply a second coat of latex paint, otherwise the wall surface will easily crack, peel, and fall off in the later stage.

2. Matters Needing Attention When Applying Latex Paint

1. Basic processing

If the old wall needs to be repainted, and the base layer has cracked or fallen off, the old paint layer should be scraped off first, the wall should be cleaned, and then polished to keep the wall flat and without potholes. Repaint after the wall is completely dry. If it is a new wall, the concrete and plaster layer itself have a high water content, so the wall must be dry before painting. If there is too much water in the wall, it will cause the latex paint to bulge, change color, alkali and other problems.

If you want to apply colored paint, be sure to stir the latex paint thoroughly before use, otherwise the color paste in the latex paint will cause uneven distribution, color shifting, etc., and the overall effect will be affected.

The painting effect of latex paint is closely related to the construction temperature, especially in the cold winter. If the temperature is too low, it is difficult to play a role, which will affect the effect of latex paint. In addition, latex paint is easy to freeze, which affects the painting quality.
