Corrosion-Resistant Coating Cracking and Treatment Methods

Corrosion-resistant coating cracking refers to the appearance of cracks of varying sizes and depths on the paint film surface. If the underlying surface is visible from the crack, it is called "cracking"; if the paint film shows a fine cracked pattern resembling a tortoise's back, it is called "crazing". So, how do you handle cracking in corrosion-resistant coatings? What measures can solve cracking and deformation?

1. How to Handle Cracking in Corrosion-Resistant Coatings

1. Small Cracks

If the cracks are small, the treatment method is relatively simple. Use a small knife to open the crack, then use coarse sandpaper to smooth the cracked area. After smoothing, apply white glue to seal the crack, followed by putty to level it, and finally reapply the corrosion-resistant coating.

2. Localized Cracking

First, remove the cracked part, then apply a crack-resistant putty. After sanding it flat enough, apply the corrosion-resistant coating again.

3. Large-Scale Peeling

If large areas of peeling appear, the above two methods cannot be used. You need to completely scrape off the wall skin, perform plaster treatment, then apply a layer of white coating or install a layer of gypsum board. After that, apply a new corrosion-resistant coating. This method is effective for large-scale peeling.

Cracking in corrosion-resistant coatings significantly affects the appearance. To avoid cracking, special attention should be paid to the maintenance after painting. There are many reasons for paint film cracking, and paying attention to details will help prevent cracking.
