The answer to 'paver yellowing' is that it is a common issue caused by a buildup of minerals, efflorescence, or oxidation on the surface of pavers. The pavers may appear discolored or have a hazy, yellowish appearance. This can be caused by factors like improper installation, poor drainage, or exposure to certain chemicals.
To address paver yellowing, you can try cleaning the pavers with a specialized paver cleaner or a diluted bleach solution. Make sure to thoroughly rinse the pavers afterwards. In some cases, the yellowing may be more severe and require professional treatment, such as grinding or sealing the pavers to restore their original color.
