Stone needs to be maintained for long-lasting durability. There are basically six maintenance measures for three-dimensional door sign stones, and each of these six measures has its own advantages and disadvantages.
1. Wax layer covering
Apply diluted wax on the surface of the three-dimensional character doorplate stone, targeting the surface of the three-dimensional character doorplate stone.
Its characteristics are low persistence, low weather resistance, requiring repeated waxing, and not conducive to removal.
2. Coating resin
Apply resin on the surface of the three-dimensional door sign stone to form a film on its surface, achieving the purpose of waterproofing and stain prevention.
The characteristic is that the gaps in the stone are blocked, which is not conducive to the breathing of the stone and can easily lead to the occurrence of new diseases such as water spots.
3. Apply silicon-based or silane based products.
Apply a silicon alkali solution to the surface of the three-dimensional door sign stone, and then apply a layer of silane based product to improve its weather resistance and prevent water infiltration. The surface of the three-dimensional door sign stone is the target of action, such as in places that often require protection.
The characteristic is the need for regular protection and a short time interval.
4. Fluorine based maintenance
To achieve the goals of waterproofing, anti fouling, and oil resistance, fluorine's hydrophobic and oil repellent properties, as well as its good weather resistance and deep penetration, can be utilized,
The characteristic is good weather resistance and durability, with good protective effect.
5. Preventing the growth of natural oil plants can be achieved by using vegetable oil
To prevent the growth of plants (lichens, mosses, algae), natural plant oils (cooked flaxseed, turpentine) can be applied to achieve the goal. The outdoor foundation, wall base, and damp areas of stone are the objects of action.
The characteristic is that this method is traditional and ancient, cannot be applied to large-scale modern buildings, and is prone to new pollution.
6. Dilute acid cleaning
Clean the surface of the three-dimensional doorplate stone with a very weak dilute acid, which can make the mineral crystals in the stone transparent and achieve the purpose of protective cleaning. The surface of stone in public places is its target.
