What are the selection and precautions of commonly used stone repellents

Modern home decoration will use a variety of high-grade stone, and each different kind of stone, in different environments and installation methods to present different effects. The correct selection of stone protective agent is the key to maintaining the quality of stone, if the selection is improper, after the construction can not achieve the expected effect, the maintenance is more troublesome.

Selection of stone curing agent 1, according to the protection requirements to choose, if the purpose of protection is to prevent panalkali, rust, etc., the general use of silicone stone curing agent can achieve the effect. If the purpose of protection is to integrate waterproof and anti-fouling capabilities, it is generally necessary to use organic fluorine stone curing agent to achieve the effect. 2. If it is a stone with a dense structure, such as white crystal, large flower white, etc., it is recommended to use oil-based stone curing agent.

Because the solvent components in it have strong penetration, they can penetrate deeper into the stone for protection. For stone with a general structure, oil-based and water-based stone curing agents can be selected. 3. If it is a restaurant, stove, driveway or other places that are easy to pollute, it is recommended to use organic fluorine stone curing agent to improve the anti-fouling ability of the stone surface.

4. If it is outdoor, you can choose silicone curing agent, but the product is required to have strong ultraviolet resistance, water resistance and acid resistance. 5. If it is installed by wet paste or grouting process, it is recommended to use a special curing agent for the bottom surface of the stone for the protective treatment of the bottom surface and four sides. The selection of the bottom curing agent should pay attention to the alkali resistance of the curing agent, and it should not affect the bonding fastness of stone and cement.

2. Precautions for the selection of stone protective agents: 1. When selecting products, do not be easily blinded by the hydrophobic effect of the surface of the product, the surface effect is only temporary, if the residual part of the surface is removed and then tested, it is the real effect of the product. 2. When selecting, it is necessary to pay attention to whether the stone curing agent will change the color of the stone after use, whether the surface residue is easy to remove, and whether it will affect the brightness of the stone surface.

3. The construction process is one of the important criteria for the selection of stone curing agent, and the process is too complex to directly lead to the rise of costs. 4. It is recommended not to use film-forming stone curing agent for smooth stone, because the surface is too smooth and will affect the bonding fastness of the curing agent. 5. Don't blindly pursue low cost and lose big because of small losses, quality first, and the second is the first principle of choosing stone curing agents.

The protective effect of any stone curing agent is relative, so when selecting products, it is necessary to choose according to the actual requirements and effects, correct construction, and strengthen post-maintenance in order to achieve the best results.

The correct selection of stone protective agent is one of the key factors to ensure the quality of stone maintenance projects. Each stone repellent is not a panacea, and its performance is mainly manifested in universal applicability, that is, it is effective for most stones. But on the other hand, each product also has its peculiarities, that is, it is particularly good or unsatisfactory or even ineffective for certain (some) performance.

Based on this, when we select stone protection agents, we must make the right choice for different stone varieties, in different environments, different installation processes and different protection requirements.

The application of stone protective agent in decoration engineering has been paid more and more attention. Its use makes the stone decoration project enter a new technical level, it can effectively avoid or reduce the generation of various stone diseases, and prevent water spots, white flowers, alkali, rust and other stone diseases. How to correctly select and use stone repellent is the key to stone protection.

The selection of stone repellents needs to advocate such a principle: scientific and reasonable selection of protectants and the correct use of repellents are indispensable. How to achieve this principle, we should first understand the classification of protective agents.

Combined with the specific requirements of our project, the protective agent is divided into: 1Waterproof type; 2.

Anti-fouling type; 3.Oil-proof type; 4.Dorsal type; 5.

Other types. If the choice is not correct, not only will the expected effect not be achieved after the protective construction, but will make the problem more serious and complicated.

Many construction personnel of stone protective agents, after using protective agents on stone, are often tested to have unsatisfactory protective effects, or even very unsatisfactory. The reason for this is nothing more than three aspects, that is, whether the quality of the protective agent is poor, which should be judged by the formal inspection; whether the construction operation is incorrect; Whether the right choice of the right variety of protective agent, which should be judged according to the variety performance of the protective agent, like travertine waterproof type, it is impossible to waterproof (because this stone itself has holes, it is easy to absorb water and store water in the moist holes). After the first condition is ruled out, the correct way to use it is extremely important.

First, the coating of protective agent must make the stone dry thoroughly:

The stone is dried so that it can fully absorb the protective agent. In order to save time and reduce costs, some builders immediately apply protective agents to some stones that have not yet dried or just been cut, so that the protective agent cannot penetrate at all due to the saturation of moisture inside the stone, resulting in poor penetration effect and poor response in protective effect.

Second, the heated and dried stone must be reduced to below 40 before the protective agent can be used.

Fourth, remove excess stone protective agent.

Fifth, the treated stone parts should be fully dried.

The selection principle of protective agent: for the selection of what kind of protective agent, we should adhere to four specific principles: specific stone, specific installation method, specific pollution source to be prevented, and specific protective agent.

1) Specific stone: first of all, we must confirm the type of stone, and investigate its color (dark, light, black, white, etc.), appearance (glossy, rough) and the texture of the stone itself (marble or granite), iron content, fierce content, sulfur content, and other characteristics of magazines;

2) Specific installation methods: should be distinguished according to the specific conditions of dry hanging, wet paving, etc.;

3) Specific pollution sources to be prevented: can be considered according to the factors such as preventing the infiltration of cement slurry, preventing acid rain erosion in use, preventing daily water-based pollution or preventing oil pollution;

4) Select specific protective agents: According to the consideration of the above three factors, determine the specific protective agents, and choose water-based, solvent-based, veneer-based, ground-based, and special protective agents.

The specific selection method can be briefly summarized as follows:

Smooth stone (especially smooth marble) should try to choose a protective agent that can increase the gloss of stone.

The decorative effect requires the use of deepening the color of the stone, and the brightening protective agent should be selected.

To maintain the original appearance of the stone, the original color of the protective agent should be selected.

When installing wet paste, the bottom surface of the stone should be selected with a protective agent that does not affect the bonding fastness of the stone and cement mortar.

Considering environmental requirements, especially when working in confined spaces, water-based repellents or repellents that do not contain organic solvents should be used as much as possible.

In places that are frequently exposed to oil stains, penetrating oil-repellent or seal-proof protective agents should be used.

For loose stone with low mechanical strength, enhanced protective agent should be selected.

The optimal application temperature of the protective agent is 5-35 °C. When the ambient temperature is too low, the water-based repellent may not be able to be applied due to icing, so an oil-based or solvent-based repellent should be selected.

1. Waterproof protective agent: it can prevent moisture from penetrating into the inside of the stone, and is resistant to acid and alkali, aging and biological erosion.

2. Antifouling protectant: This protecting agent can prevent fouling on the surface of the stone, which is very important for many stones that need to keep the surface clean or have a natural frosted feeling.

3. Comprehensive protective agent: excellent oil-proof function, anti-aging precursor, can protect many self-regret and defense phenomena, and it also has the function of waterproof stone anti-letting rental agent.

The above is an introduction to the role of stone repellent, I hope it will be useful to you!

The function of stone repellent is to make the stone have the functions of waterproof, anti-fouling, acid and alkali resistance, anti-aging, anti-freeze-thaw, anti-biological erosion, etc., so as to prolong the service life.

Its specific functions are: 1. After the application of waterproof protective agent, it can prevent water from penetrating into the stone, and also has the functions of anti-fouling, acid and alkali resistance, anti-aging, anti-freeze-thaw, and anti-biological erosion. Such as acrylic, silicon acrylic and silicone stone repellents.

2. Anti-fouling protective agent is specially designed for anti-fouling on the surface of stone, and its functionality mainly focuses on anti-fouling performance, and other properties and effects are general. Such as vitrified tile surface antifouling agent, etc. 3. In addition to excellent oil-proof, anti-fouling and anti-aging properties, the comprehensive protective agent also has all the functions of waterproof stone protective agent.

4. The professional protective agent is specially developed for the special functional requirements such as glazing and color enhancement on the stone surface. Such as color-enhancing stone protective agent, brightening stone protective agent, etc. 5. The stone curing agent that can be dissolved by water is called water-based stone protective agent.

Such as water-based protective agents, water-soluble solvent-based protective agents, emulsion-based protective agents, etc. This type of repellent generally has relatively weak penetration (except for water-soluble solvent-based repellents), but the toxicity and odor are relatively small, and they are non-combustible. It is suitable for the protective treatment of loose stone surfaces.

The principle of action is: the polymer stone protective agent is injected into the capillary pores of the stone through the solvent, and after a short period of penetration and volatilization, it will leave the anti-fouling resin component and fill the pores to prevent the stone from absorbing water and pollution.

When selecting stone protective agents, in addition to having a good protective effect, we should also consider the type of stone, the surface condition of the stone, the decorative effect required by the stone, and the influence of various factors such as climate and environment. Different protective agents may have different protective effects on stone, and should be treated differently when selected. In addition, the most important point is that no matter what kind of protective agent is used, before large-scale construction, you should first make a local test, even if it is a protective agent that you are familiar with, so that the protective effect is recognized by the other party, and at the same time, you should also know what to do to prevent accidents due to poor consideration.

There are many times of the year when you encounter rain, high temperatures, humidity and other climates, so if you decorate during these times, many quality problems will occur, but if you pay attention to important matters, many problems can be avoided.

Because stones such as marble and granite are natural stones with complex compositions, they are prone to corrosion in the environment, white bloom and other common diseases of stone. The consequences of these problems are very serious, and the losses caused are also very large, so the effective protection of stone has become particularly important.

Usually we use waxing and other protective measures, but the waxing has poor weather resistance and the protective effect is not very ideal. And waxing will also cause some damage to the stone. We all know that the protective principle of waxing is to cover the surface of the stone with a film.

Moreover, there are many holes and gaps on the surface of the stone, and the stone waxing will block these holes and gaps, causing damage to the stone.

During the long-term development of science and technology, people have gradually improved various forms of stone repellents and upgraded them.

At present, penetrating stone protective agents have been widely used in the stone protection industry. It can bring the stone protective material to the inside of the stone through solvents, so as to form a protection against the stone. Penetrating stone repellent can achieve a longer effect on stone protection.

It not only protects the stone but also saves costs.

So is there any good stone repellent that you can recommend now? In fact, there are many types of penetrating stone repellents, including silicon-containing and fluorine-containing materials. Silicon-containing stone repellents can brighten and brighten the stone, but if you don't want to change the original color of the stone, you can use fluorine-containing stone repellents.

SINO2500 is a fluorine-containing stone repellent, which does not change the natural texture of the stone, but also maintains the air permeability of the stone, and its performance is superior, scientific and reasonable. However, due to the difference in the materials used, some products will be different in waterproof, anti-fouling, and oil-proof effects, but most products have better effects.

In home decoration, many people do not understand what the stone curing agent is for, in fact, it is a product that can play a preventive and protective role in the stone, and its most basic protection for the stone is waterproof, so how to use the stone curing agent? Let's take a look at the use of stone curing agents and the precautions for using stone repellents.

First, the use of stone curing agent.

1. The use of the oven to dry the slate, some companies in order to save costs cut corners, and do not dry the stone in advance and directly use the stone curing agent, resulting in poor maintenance effect. In fact, drying the slate is a very critical step, the main reason is: drying the slate can remove the moisture in the cracks of the stone, so that the stone curing agent can be smoothly soaked to a sufficient depth, and at the same time has a very deep field stove cleaning and maintenance function.

2. The stone needs to rise to 40 before the curing agent can be used, the main reason is that the temperature is high, the solvent evaporates quickly, and the curing agent hardens on the surface of the stone in advance, resulting in insufficient penetration depth, the deep protection effect of the stone curing agent is very poor, and the water spot substance can invade the line of sight.

3. The curing agent is particularly critical in terms of dosage. In the process of use, the dosage of stone curing agent must be sufficient, otherwise the stone absorption is not enough to achieve the maintenance effect.

4. Use a brush to paint evenly as much as possible, so that the stone curing agent can be very evenly soaked into every part of the outer layer of the stone, so as to prevent a large amount of local use. Otherwise, the maintenance is strong, but the local use is not enough, and the lesion components are infiltrated.

5. During the use process, it is necessary to quickly use a rag to wipe off the remaining stone curing agent to prevent the remaining stone curing agent from hardening the surface of the stone, which will affect and damage the gloss of the stone to a certain extent.

Second, the use of stone protective agent precautions.

1. You can't just believe in the instructions on the product, no matter what product is required to pass the on-site test, and only after passing can you determine whether it can be selected.

2. When choosing a product, do not be deceived by the appearance of the product hydrophobic function, the effect of the appearance is generally short-lived, if you remove the remaining part of the appearance, and then pass the test in the future, it is the real effect of this product.

3. When selecting, it is necessary to pay attention to whether the original color of the stone has changed after the use of stone curing agent, whether the remaining surface can be well removed, and whether it will affect the gloss of the stone appearance.
