water spot is a kind of disease that is often encountered during the use of soft porcelain-flexible stone, and it mostly appears on the soft stone. Water spots are always repeated and difficult to eradicate, so they are called "flexible stone-soft porcelain cancer". Next, the soft porcelain manufacturer will explore the ideas and methods for the treatment of water spots.
1. What is water spot?
1. Definition of water spots
Using the cement wet paste method, when the soft porcelain-flexible stone is installed, the hygroscopic substance penetrates into the soft porcelain-flexible stone, making the appearance of the wet mark that is not easy to dry naturally.
2. Features of water spots
① There are visually similar traces of water wetting.
②Always do not dry, or it is not easy to dry completely.
③Even after sunlight or fire, the wet mark remains.
3. Causes of water spots
①Alkaline in cement
The soft porcelain-flexible stone wet with cement will migrate and solidify to the surface of the soft porcelain-flexible stone by long-term contact with water, forming an "alkali-silicate gel." This material has a very strong water absorption capacity. After absorbing water, it will change the light reflectivity of the soft porcelain-flexible stone, showing a wet visual result.
②External salt and alkali
Strong alkaline cement, inferior cement, cement additives, flexible stone-cushion soil, silt under soft porcelain, hygroscopic salt left by strong acid cleaning and pollutant reaction, inferior protective agent, acid rain or acid mist and flexible stone-soft Hygroscopic salt generated by the reaction of porcelain components, etc.
③Contact with water
Situation 1: Direct or indirect contact with water. Such as contact with moist soil, high groundwater level, nearby pools, toilets, roof water, and poor drainage.
Case 2: The contact with too much water during installation and use. If the panels are always wet before installation, are exposed to rain, the cement is too thin or too much during paving, and the installation is not dry, rinse or flood with plenty of water.
④False water spots
Situation 1: If the soft porcelain-flexible stone is in a wet condition for a long time, the appearance is easy to absorb dust. After a long time, pollutants penetrate into the micropores of the flexible stone-soft porcelain appearance, and the water will leave traces of water spots when the water dries.
Case 2: Some liquid substances, such as glue, pollutants, inferior protective agents, and soft porcelain-flexible stone micropores, will also leave traces similar to water spots.
Strictly speaking, these two types are not really water spots, because their pollutants are not hygroscopic substances. Therefore, it is often referred to as "false water spots."
2. The idea of controlling water spots is very simple
Water spot treatment, only by strictly following the ideas and steps of "cutting water, opening the appearance, treating water spots, and protecting" can we achieve excellent results.
Three, governance methods
1. Water cut
Water cut is the key to the treatment of water spots. Cutting off the water source may seem simple, but it is actually a complicated judgment and implementation process. Because it is necessary to cut off, not only the visible water source, but also various sources of moisture, moisture, and water seepage. There is no omnipotent solution to this step. It is necessary for everyone to mobilize their own ingenuity and consider every situation and every detail in order to solve the problem.
2. Open the appearance
Through grinding, slitting, etc., the contaminated layer, crystal layer, and protective layer are opened. The soft porcelain-flexible stone can have space and passages to disperse the absorbed water. Without this step, it is difficult for the soft porcelain-flexible stone to disperse the absorbed water, and the subsequent water spot treatment will lose the result and meaning.
3. Treat water spots
①Physical drying
Open doors and windows for ventilation, use a blower, turn on floor heating, use sun lamps or infrared lamps, microwave or electromagnetic heating, use desiccant (such as calcium chloride or lime) to absorb and other methods to accelerate the emission of moisture.
②Chemical cleaning
Use the soft porcelain-flexible stone water spot killer to clean, eliminate or destroy the salt-alkali and gel forming the water spot in the soft porcelain-flexible stone, and make it lose its moisture absorption ability.
③Chemical cleaning + physical drying
First use cleaning agent to destroy or destroy the salt and alkali and gel in the soft stone-soft porcelain, and then use physical methods to eliminate the water in the soft stone-soft porcelain.
④Brightening toning
Darken the light-colored part of the water-spot soft porcelain-flexible stone to achieve the same or close overall color.
4. Protect yourself
After the water spots are eliminated, protection must be done, and water-based protective agents can no longer be used, and high-quality penetrating (oil-based) protective agents should be selected. Use a roller, brush, or sprayer to spray. Brushing standard: sufficient, even, keep for more than 24 hours.
Fourth, the prevention of water spots
To prevent water spots, the owner, designer, and paving party all have tasks and responsibilities.
1. The owner
①It is recommended that the owner choose soft porcelain-soft stone with compact structure and low water absorption.
② Dry hanging is recommended for walls, and special soft porcelain-flexible stone glue is recommended for paving on the ground instead of cement.
2. Designer
①When designing, consider the moisture-proof measures under the flexible stone-soft porcelain, such as moisture barrier. Avoid direct or indirect contact of soft stone-soft porcelain with moisture and water sources.
②When designing, reserve water vapor channels in the paving cement mortar layer. For example, some breathable pipes can be installed to make the water vapor escape from the pipes as soon as possible.
3. Paving party
① Avoid using low-quality cement.
② Use as little water as possible during the paving process, such as using semi-dry mortar and scraping to reduce the amount of mortar.
③ During the paving process and maintenance period, avoid raining or washing the flexible stone-soft porcelain.
④Do not use strong acid to clean cement spots and rust yellow.
⑤ Avoid immersing the installed soft porcelain-flexible stone in water or staying in a wet condition for a long time.
Water is the source of many problems in stone. Therefore, the key is prevention. The key to prevention is to cut off the way for water to penetrate into the soft porcelain. Therefore, all aspects of design, material selection and construction should be consciously prevented to avoid the appearance of watermark-like chromatic aberration, so that the decorative materials are truly colorful Effect.
