How to solve the defects on the surface of stone balls? If there are defects on the surface of stone balls, they can also be remedied, just like how our skin may wrinkle or develop spots if it is too dry, which directly affects our image. In this case, skincare products are needed. And the stone uses cleaning agents. Due to being exposed to sunlight and rain all year round, stone balls may rust, turn yellow, and have potholes over time. Therefore, it is essential for maintenance workers of stone balls to regularly inspect and repair them in order to prevent greater losses. Today, let me tell you how to solve the surface defects of stone balls:
One is to solve the problem of yellowing of stone balls caused by rainwater erosion:
Solution: First, use a cloth to dry the surface of the stone ball and remove any dirt that has infiltrated the inside of the stone ball. Then apply rust remover to the yellowed areas of the stone balls and thoroughly clean them with clean water. If it is a large or dark rust stain, polishing abrasive is needed to remove the yellow spot. One thing to note is that the rust remover needs to be diluted with water before use, otherwise it will damage the surface of the stone ball.
The second is to solve the problem of oil stains on the surface of stone balls:
Solution: Due to the saponification and emulsification effects of alkaline solutions (sodium hydroxide, sodium carbonate), the dirt becomes loose and dispersed. Plant oil stains are more easily saponified, but if mineral oil pollution occurs, emulsifiers need to be used to first reduce the adhesion of the oil stains on the surface of the stone balls, and then clean and remove them.
The third is to solve the problem of stone ball cracks and damage:
Solution: First, clean the cracks on the stone ball, remove loose gravel, and dry the surface. Then apply a layer of transparent primer and fill it with mortar of the same color as the stone balls. After it dries, polish it to make it smooth, and then remove any excess parts.
