Special Prevention and Treatment of Alkali in Toilet Stone
Toilet stone is located in a complex environment where it is exposed to a large amount of cold and hot water every day. The space is limited, and the air flow is poor. Long term exposure to various chemical liquid powders such as hand sanitizer, shower gel, laundry detergent, and even some metabolic substances residue in the human body can easily lead to problems with stone in this environment.
One day when you walked into the bathroom, you suddenly noticed that the luster of the stone seemed to be covered by something. Looking at the surface, it was white and hazy, and feeling dusty with your hands. Even upon closer inspection, it was found that there was white powder in the pores of the stone. With a needle, a soft and white plaster like “white strip” flowed out from the joint of the stone on the wall.
If this situation occurs, it can be basically determined that your stone has returned to alkali.

In the special environment of the bathroom, there are also special requirements for treating stone alkali.

Stone whitening
Stone efflorescence refers to the white powdery substance left by the alkaline substances in cement when wet applied with cement mortar, using water as the medium, reaching the surface of the stone through the joint gaps or pores, and drying. The alkaline substances in stone that have not been treated for a long time react with carbon dioxide, sulfur dioxide, and other substances in the air, forming various substances such as calcium carbonate, calcium hyposulfate, and calcium sulfate, which are called Baihua.
So, Baihua is an upgraded version of alkali recovery. The governance principles of both are the same.
Solution principle
The key point to control the alkali returning white hua is to cut off water, and to control the alkali returning of stones when they are dry is twice the result with half the effort. Clean the dirt on the surface of the stone, blow dry or dry the stone, and then use chemical agents to neutralize the alkaline substances in the surface and micropores of the stone. After washing with a large amount of water, the water in the stone will be dissipated. Finally, through protective treatment, the micropores and micropores of the stone will be closed, and the alkali can be eradicated.
Specific steps:
1. Cut off water
Do not allow visible water in the bathroom;
2. Drying
Keep the stone dry, open windows for ventilation, use drying or blowing methods, and choose according to your own tools;
3. Cleaning
Mild alkali return can be washed and dried with a large amount of water. Severe alkali return needs to be cleaned with a stone specific white flower remover mixed with water. In case of white flower, first use a shovel to remove surface attachments, then use white flower remover mixed with water to clean, and finally use a large amount of water to wash away the cleaning material. The reaction time between Baihua scavenger and alkaline substances is recommended to be around 10 minutes.
4. Protection
The “water in oil” protection method is cost-effective and efficient
First pass: Soak the foundation with water-based protective agent
VD composite silane protective agent can be selected, mixed with water at a ratio of 1:13. Then pour a sufficient amount of mixed solution directly onto the surface of the stone, spread it evenly, and let the stone fully soak. If the protective agent absorbs and dries quickly, add more.
Only when a layer of wet protective agent appears on the surface of the stone and it does not dry for more than 2 hours.
Second pass: Strengthen treatment with oily protective agent
VD fluorine based protective agent or penetrating protective agent can be selected, poured in sufficient amount on the surface of the stone, evenly spread out, and let the stone fully soak. If the protective agent absorbs and dries quickly, add more.
Only when a layer of wet protective agent appears on the surface of the stone and it does not dry for more than 2 hours.
② Wall anti-seepage treatment
The protection of wall stone can refer to the above principles and be applied multiple times with tools such as a brush until a good anti-seepage effect is achieved.
5. Sealing glaze
Use a crystal face machine and a cleaning pad to seal the glaze.

If there are black and broken joints in the stone, it is necessary to clean and fill the glue first. If the stone is loose, first fill the glue, and then brush the protective agent. This can avoid wasting the protective agent, and secondly, the glue will not stick firmly after protection.

Try to avoid using seam sealants to fill stone gaps in the bathroom. The faucets in the bathroom and other areas have a certain amount of pressure when spraying water, and seam sealants cannot withstand the pressure. Glass glue is prone to mold, so it is also important to avoid using them.

Do not crystallize in the bathroom. The principle of crystallization technology is to use materials such as oxalic acid, fluorosilicic acid, and metasilicic acid to react with the calcium on the surface of stone, forming a calcium crystalline layer. In a watery environment in the bathroom, the calcium crystalline layer can be dissolved by water. In addition, the calcium layer has a soft texture and is prone to wear and tear, resulting in poor durability.

Prevention of Stone Lesions in Toilets
1 Protection:
Before installation, provide six sided protection for the stone. Six sides refer to: surface, bottom, and four sides. Among them, the bottom surface needs to be bonded to the surface of the building. In order to avoid the influence of ordinary protective agents on the bonding force, special “stone bottom protective agent” needs to be used for the protection of the stone bottom surface.
Use VD stone bottom protective agent and VD permeable stone protective agent to protect the stone for 2-3 times.
Protective construction standards: sufficient, uniform, and maintained for at least 24 hours.
2 Paving:
The use of adhesives instead of cement in bathroom stone paving can cause alkalization and whitening of the stone in a water rich environment, and the use of adhesives can avoid the vast majority of problems caused by water.
3. Close fitting installation:
When installing bathroom stone, do not reserve gaps, but use close fitting installation. When installing, high-quality marble adhesive should be applied to the four sides of the stone, and then the stone should be tightly butted with force, with the narrower the gap as possible.
The corners of the stone and the joints with the wall should be repaired with glue. It is recommended to use porcelain glue for bathroom glue repair. The porcelain glue should be smooth and waterproof to avoid mold when using glass glue.

Porcelain glue patching

Physical polishing+sealing glaze:

By using physical grinding, the luster of the stone itself is achieved. The physical glossiness of the stone itself is super wear-resistant, and with a hard, dense, and insoluble silica protective layer, it can ensure that the stone remains beautiful for a long time in a watery environment like the bathroom.
