How to deal with the yellowing of the rainy season Landscape Stone?

1. The treatment method for the yellowing of the surface of the Landscape Stone eroded by rainwater

First dry the stone carving with a rag, clean up the stains that have penetrated into the Landscape Stone, and then apply the rust remover to the yellowed part of the Stone Carving, and then rinse it with clean water. If the rust is large or the color is deep, you need to use polishing abrasives to clean the yellow spots. It should be noted that the rust remover needs to be diluted with water before use, otherwise it will damage the surface of the stone carving.

2. The problem of oil pollution on the surface of Landscape Stone
Use the saponification and emulsification of alkaline solutions (sodium hydroxide solution, sodium carbonate solution) to loosen and disperse stains. Vegetable oil stains are more prone to saponification. If it is mineral oil, you need to use an emulsifier to reduce the adhesion of the oil on the stone carving surface before cleaning.
3. Cracking and damage of Landscape Stone
First clean up the damaged and cracked parts of the Landscape Stone, clean up the loose gravel, and dry the surface. Then apply a transparent primer, fill it with mortar of the same color as the stone carving, let it dry, and then sand it smooth, and clean up the excess. When pasting stone sculpture, first spray or roll-coat the inside and side of the stone sculpture with 0.2~0.3kg/m3 of protective treatment agent, and then paste it on the wall of the building to the ground. After 1-2 hours at room temperature, the protective treatment agent is cured, so that the stone sculpture can be fully attached to the wall or the ground.
Since the riverside is a relatively dangerous place, if stone sculpture are not installed, there is a high possibility of accidents for pedestrians and vehicles passing by, such as falling into the water, and the use of river Landscape Stones can avoid accidents. If danger occurs, it can have the effect of supporting and save a life if necessary, so the use of Landscape Stone is necessary.
The installation and use of river Landscape Stones can also have a good decorative design effect and decorate the surrounding architectural environment.

No matter what kind of stone sculpture are carved, the railings are very beautiful, delicate, elegant, and simple. They are installed and used beside the river. It can beautify the environment well.
