One, how to maintain fire-resistant coating after application
1、Promptly remove the protective film.
After applying fire-resistant coating, promptly remove any masking materials used for color separation, protection, or other purposes. If these materials are removed after the wall coating has dried, it may result in uneven coating.
2、The wall surface must be protected before drying.
Before applying the fire-resistant coating, it is important to close doors and windows to prevent contact. Do not place tools such as shovels against the wall. It is best to wait a few days before returning items placed against the wall to their original position, as this may scratch or leave noticeable marks on the wall. Also, avoid cleaning the floor immediately after applying the fire-resistant coating, as this may damage the freshly applied coating.
3、After the wall coating dries, ensure adequate ventilation.
When applying fire-resistant coatings, ensure adequate ventilation after drying. However, during the drying process of fire-resistant coatings in winter, if the indoor temperature is too low, it can affect the coating's performance. To ensure proper coating, take necessary measures to increase the temperature and protect the fire-resistant coating.
4、When placing large furniture, be sure to protect the walls.
- Large furniture items such as beds and wardrobes should be kept a certain distance from the walls during moving and placement, or the walls should be appropriately protected to prevent scratching or damage to the fire-resistant coating.
II. Fire-Resistant Coating Application Precautions
1、Different types of coatings have different functions and application methods. First, we need to have a basic understanding of the performance of fire-resistant coatings and apply them according to the instructions.
2. Before application, thoroughly clean the surface of the substrate to remove any rust, oil, and other contaminants. Ensure the surface is completely dry before proceeding with the application, as the performance and lifespan of the coating are highly dependent on the quality of the surface preparation.
3. When using fire-resistant coatings, due to the time elapsed from manufacturing to use, some sedimentation may occur. Therefore, it is essential to thoroughly mix the putty powder before use.
4. When applying multi-layer fire-resistant coatings, the top layer coating should only be applied after the bottom layer coating has completely dried. If the bottom layer coating is not fully dried, it is easy to cause wrinkles and detachment of the bottom layer coating.
