How to make putty dry quickly in winter? What should you pay attention to when scraping putty?

There are many additives in putty, which need to be dissolved at a certain temperature. If the temperature is too low, the dissolution rate of these additives will be very slow and they cannot be fully dissolved, which will directly affect the film-forming speed and quality of the putty in the later stage. Therefore, the time and method of applying putty are also important. The following is a detailed introduction on this aspect, please open and read carefully.

How to make putty dry quickly in winter

Heat the room, for example, light a fire. Putty can be applied in winter. Putty powder contains many chemicals. Applying putty in winter can speed up the volatilization of formaldehyde and reduce the time these toxic gases remain in the room. The temperature is lower in winter, which can avoid the powdering and cracking of putty to a certain extent, and the film-forming effect will be better.

If the putty on the wall of your home has frozen due to low temperature, don't be afraid. Use a blade or other similar object to scrape off the frozen part of the wall, then soak a towel with water and additives, and gently wipe the frozen area. When the temperature rises, you can resume construction.

What should I pay attention to when scraping putty?

1. The ratio of water and putty must be correct so that the construction effect is good.

2. When scraping putty, make sure it is level so that the surface will be flat and smooth after construction is completed.

3. Putty is usually applied 2 to 3 times. During construction, each coat must be dry before the next coat can be applied.

4. It is important to control the inclination of the tool when scraping and apply force evenly to ensure the fullness of the putty.

5. Do not scrape back and forth continuously to avoid peeling, falling off, and squeezing out of the glue in the putty, which will affect the construction quality.

6. Do not clean the room before the putty dries, for fear that dust will stick to the wall putty and make it unsightly.

Precautions for scraping putty in winter

Putty powder in winter has certain temperature requirements, usually above 5 degrees Celsius. There are many additives in putty, which need to be dissolved at a certain temperature. If the temperature is too low, the dissolution rate of these additives will be very slow and cannot be fully dissolved, which will directly affect the film-forming speed and quality of the later putty.

Putty powder cannot be used on the same construction surface with other putties to avoid chemical reactions and color differences.

Putty powder should be used within 4-5 hours after being mixed into a paste to avoid deterioration over time. If the temperature is too low, the putty will easily crack.

Scrape the putty evenly: Before scraping the putty in winter, fill the cracks of the base first, and the putty must be scraped evenly. Because the putty needs to be scraped in layers, if one layer is scraped too thick, it will take a long time to dry, which will affect the construction of the next layer.
