Blistering on the surface of furniture is usually caused by certain problems or improper operation. Here are some possible causes of surface blistering:

       1. Glue problem: If the glue used in manufacturing is inappropriate or of poor quality, it may cause bubbles to form during the drying or curing process of the glue. These bubbles can cause surface blistering.

       2. Humidity problem: Manufacturing or spraying in a high-humidity environment may cause the coating to be uneven. Moisture enters the coating and evaporates during the drying process, causing bubbles.

       3. Improper surface preparation:furnitureImproper surface treatment and preparation, such as not cleaning, not sanding, or insufficient sanding, will affect the adhesion of the coating and cause the coating to blister.

       4. Too thick coating: Too thick a coating may produce bubbles during the drying or curing process. This usually occurs when too much is applied in one application.

       5. Insufficient drying of the coating: The coating does not have enough time to dry or cure. When the surface of the coating has begun to solidify, the bottom still contains volatile components, which may cause bubbles.

       6. Temperature issues: Bubbles may occur when the coating is dried or cured at inappropriate temperatures. Too low a temperature will slow down the drying process and prevent volatile components from escaping in time.

       7. Construction technical issues: Improper coating construction technology and operation may also cause bubbles. For example, uneven force, too fast or too slow construction may cause bubbles.

       8. Coating formula issues: The formula and ingredients of the coating may cause the coating to be unstable and prone to bubbles.

       In order to solve the problem of blistering on the furniture surface, it is necessary to carefully analyze the specific cause of the problem and then take corresponding measures. This may include changing to a better quality glue, controlling environmental humidity, improving surface preparation, ensuring that coatings dry adequately, optimizing application techniques, etc. When manufacturing furniture, ensure the correct materials and processes are used to reduce the risk of surface blistering.
