Determine whether the self-adhesive mosaic tile fiberglass mesh is damp or corroded

The self-adhesive mosaic tile fiberglass mesh should be used in a dry state. The damp or corroded self-adhesive mosaic tile fiberglass mesh will affect the construction effect. So what are the methods to determine whether the self-adhesive mosaic tile fiberglass mesh is damp or corroded? The editor summarizes it as follows:

The first is to look visually to see if there are obvious abnormalities in the self-adhesive mosaic tile fiberglass mesh. If it is moldy or corroded, there will generally be obvious changes in appearance, which can be distinguished by the naked eye. Second, you can use measuring tools to measure whether there is shrinkage or expansion.
Deliquation will cause the self-adhesive mosaic tile fiberglass mesh material to absorb water and expand. If it is corrosion, it may cause the structure of the self-adhesive mosaic tile fiberglass mesh to be damaged and the size and length to change. In addition, you can also feel the texture of the self-adhesive mosaic tile fiberglass mesh by touch to see if there are any rough or fragile places.
The third is chemical composition analysis to detect whether it contains excessive moisture or corrosive substances. This usually requires professional laboratory equipment and technicians to complete. Carry out storage environment conditions to understand the situation of the self-adhesive mosaic tile fiberglass mesh, such as humidity, temperature, and whether there are corrosive gases or liquids.
These factors may affect the durability of the self-adhesive mosaic tile fiberglass mesh. If the self-adhesive mosaic tile fiberglass mesh is in a harsh environment for a long time, the risk of deliquescence or corrosion will increase. If possible, check the production, transportation and storage records of the self adhesive mosaic tile fiberglass mesh.
Understand its environmental exposure throughout its life cycle. If the records show that the self adhesive mosaic tile fiberglass mesh has been exposed to extreme or corrosive environments, it is more likely to be deliquesced or corroded. Through these comprehensive testing and analysis methods, it can be determined whether the self adhesive mosaic tile fiberglass mesh has been deliquesced or corroded, and the potential extent of the impact.
