What causes paint blistering to recur? Three culprits revealed by the contents.
If you split open the bulge and look inside, you will understand the cause. This explains how to distinguish between three patterns: water, rust, and cavities, as well as points to reconsider in the process to prevent recurrence.
Even after repainting, the same area swells up again. Please cut open the swelling once and take a look inside. 【First, please look here】 □ The inside is damp and water is coming out → Moisture and salt from the pre-treatment remain □ The inside is brown and rusty → Rust from before painting or rust spreading from scratches in the substrate □ The inside is dry and only hollow → Gases or solvents inside the material have not fully escaped 【Why does it keep happening?】 Simply repainting from the top leaves the cause of the swelling still underneath the paint film. If you take measures without checking the contents, it won't stop even if you change the paint. 【Countermeasures you can take starting today】 1. Break three swollen parts and record the contents 2. If it's water, wash and dry; if it's rust, remove the rust; if it's hollow, review the drying process 3. Compare the number of swellings in three batches after the countermeasures 【Free materials】 You can download a guide summarizing how to identify and address painting troubles for free from the related catalog on this page.
