Who knows what kind of glue is used to fill cracks in stone blocks, I heard that Shuitou has bought,

With "502 glue", the glue is a colorless transparent liquid, and its properties are transparent, colorless, high strength and good permeability.

Generally, marble glue (stone glue) is used, and there are also transparent ones.

As a high-grade building decoration material, stone is widely used in indoor and outdoor decoration design, curtain wall decoration and public facility construction. At present, the common stones on the market are mainly divided into natural stone and artificial stone. Natural stone is divided into slate and granite according to its physical and chemical properties.

Artificial stone is divided into terrazzo and synthetic stone according to the process. Terrazzo is made of cement, concrete and other raw materials forged; Synthetic stone is made from crushed stone of natural stone as raw material, plus binders and other materials through pressure and polishing. The latter two are artificially made, so the strength is not as valuable as natural stone.

Stone is a high-grade product of building decoration materials, natural stone is roughly divided into granite, slate, sandstone, limestone, volcanic rock, etc., with the continuous development and progress of science and technology, artificial stone products are constantly changing with each passing day, quality and beauty has not been inferior to natural stone. With the development of architectural design, stone has long become one of the important raw materials for construction, decoration, road and bridge construction.

You can use a high-strength penetrating adhesive, which has strong penetration, and cracks, cracks, dark cracks, and chicken claw lines can be repaired.

Stone crack bai repair can be repaired with cracks.

Du glue zhi for repair;

Mending Crack DAO: Specialized.

First of all, the dirt in the crack must be cleaned up;

Then use a vacuum cleaner to suck up the dust in the crack (you can also use a hair dryer to blow away the dust);

Finally, the crack repair glue is used to repair the cracked places;

Note: Clean the dirt and dust as clearly as possible to avoid the adhesive of the image crack repair adhesive;

It is recommended to repair it with marble glue, and then polish it after drying!

Repair with marble glue.

BAI specific steps:

First of all, the dirt in the cracks must be cleaned up;

Then use a vacuum cleaner to suck up all the dust in the crack (you can also use a hair dryer to blow away the dust);

Finally, the cracks are repaired with marble glue, and smoothed after drying.

Note: When cleaning dirt and dust, it should be as clear and clean as possible, so as not to affect the adhesion of marble glue;

It is recommended to go to the Xiamen Stone Exhibition to see the event fixed on March 6-9 every year, and if you are optimistic, you can pick up the goods directly from Adong Shuitou.

It is repaired with WJ-401 epoxy resin glue with high strength. Bridge cracks are widely used!

How to use and how to use the key points of construction.

a. Treatment of crack surface B. Glue adjustment C. Seam sealing D. Setting glue injection nozzle E. Pressure glue potting.

1. Crack treatment.

For cracks in smaller concrete components, use wire brushes and other tools to remove dirt such as dust, scum and loose layers on the surface of concrete cracks, and brush off floating ash; Wipe clean with alcohol in the range of 2-75px along both sides of the crack.

For larger concrete components or deep cracks, drilling and glue can be poured along the cracks, so that the glue has a wider passage into the cracks.

2. Set up the base of the glue nozzle.

Glue nozzles must be set at the staggered place of the crack, the wide part of the crack and the end of the crack. The spacing of the grouting nozzle can be determined according to the size, direction and structural form of the crack, and the general spacing of the grouting nozzle is 20-750px. A crack must be provided with a glue inlet, exhaust or glue outlet.

The base of the nozzle can be pasted in the predetermined position with seam sealing glue first, or it can be pasted together when sealing.

3. Seam sealing. The quality of the sealing seam directly affects the grouting effect and quality, and special attention should be paid to it. Sealing glue can be used for the sealing of cracks, and the sealing glue can be weighed and mixed according to the recommended glue ratio. Use a putty knife to apply and scrape along the cracks repeatedly, and then evenly apply a layer of cement with a thickness of about 1-2mm and a width of not less than 30mm, paying attention to prevent small bubbles or poor sealing.

4. The seam sealing glue cures quickly and bonds firmly, and needs to be used with it, which is a special glue for crack sealing and pasting the base used in the automatic pressure grouting process. Glue can be injected 10 minutes after the seam is intact.

5. Prepare and pour glue solution for continuous glue injection.

Special glue injection equipment should be used for glue injection operation. Prepare the grout resin in proportion, pour it into the hose, screw the grout filled with resin onto the base, and release the spring for glue injection. Depending on the size of the crack area, single-hole grouting or zoned group hole grouting can be used.

The grout on a crack can be shallow to deep, from bottom to top, from one end to the other. Resin deficiency can be replenished repeatedly. The automatic pressure grouting device often used for grouting pressure can obtain better grouting effect by using lower grouting pressure and longer grouting time to ensure smooth grouting under the condition of ensuring smooth grouting pressure.

When the last grouting port is dispensed and the dispensing rate remains stable, the grouting can be stopped by holding the pressure injection for about 10 minutes. Remove the grouting device and rotate the plug to the base to prevent the glue from spilling.

6. Glue curing.

WJ-401 grouting resin (crack repair) adhesive should be cured in an environment of more than 5, and the curing time depends on the ambient temperature. Under normal circumstances (25), it is enough to fully cure for 2-3 days.

7. Glue filling effect inspection.

After the grouting is completed, the grouting effect and quality should be inspected, and if there are unqualified conditions such as non-compactness, supplementary injection should be carried out.

Repair cracks with self-healing waterproof sealant.

How to use: 1. Surface treatment: Before construction, the oil, attachments, and dust on the inner surface of the joint should be removed to ensure that the inner surface of the construction joint is dry, smooth and clean, and to prevent poor bonding.

2. Take the material according to the specified proportion, fully mix and stir evenly until the material does not contain aggregates, and the color difference is consistent (the stirring time is more than 3 minutes, and it is best to use electric stirring).

3. Fill the stirred self-healing waterproof sealant into the joint with a gray knife or glue gun to compact and fill it to ensure that the bonding is tight, and then scrape it flat with a putty knife.

4. After scraping, the finished product is protected to prevent the construction joint from being damaged.

5. After the self-healing waterproof sealant is fully cured, it is sealed with rigid consolidation materials such as instantaneous plugging agent to ensure that the cured self-healing waterproof sealant is always in a constrained state.

Marble gum can be used.

Marble glue is made of epoxy resin and unsaturated resin, and some of the marble glue made of unsaturated resin can be cured in a humid environment, and the effect is also very good.

In addition, the excellent properties of marble glue are mainly reflected in hardness, toughness, rapid curing, polishability, weather resistance, corrosion resistance and other aspects.

At present, marble glue has been recognized by the majority of stone users and the construction industry, and is suitable for bonding between various types of stone or repairing cracks and fractures on the surface of stone, and is often used for repairing, bonding positioning and caulking of various types of stone paving projects and various types of stone.

Special attention should be paid to the fact that marble glue should never be used for pasting large areas.

A1Stone sticks to other items with epoxy adhesive works best. The stone is uneven and rough, and there are many gaps in the contact surface that need to be filled with adhesive, so epoxy adhesive works best.

2. If the stone is broken, it needs to be bonded, because the seam only needs to be bonded and does not need to be filled, use 502 glue, so that the traces of bonding are small.

Marble glue is a two-component glue widely used in various stone bonding (low strength requirements), filling, positioning and other aspects. Most of them are composed of unsaturated resin or its modifiers (component A), peroxide and other additives constitute component B (component B), commonly known as stone AB glue. When using, the AB component is mixed evenly in proportion and applied to the stone, which can be cured quickly at room temperature to play a bonding role.

Marble glue is currently one of the most commonly used adhesive types for stone bonding applications. Marble glue has many characteristics: such as fast curing speed, it is the use of free radical polymerization mechanism of the main resin and initiator (peroxide), and the amount of initiator can be used in on-site construction, and the curing time can be adjusted within a certain range (from a few minutes to dozens of minutes), even in winter 0 time can be constructed.

Marble gum can be formulated in a variety of colors. Such as white, red, blue, green, gray, black, etc. can also be matched into translucent colorless colloid, which can be used to caulk, repair, and maintain the consistency and beauty of stone tones with different colors of stone and patterned stones. Marble glue has relative bonding strength for a variety of stone and building materials, and is widely used in indoor stone decoration, stone furniture bonding, stone batai, stone handicrafts, etc.

Marble glue also has good construction performance, most of which are thixotropic glue. Good spreadability, easy construction, easy to remove residual glue, it is widely used an important reason is that the manufacturing raw materials are extensive, easy to obtain, and the products are cheap, so they are very popular with users. Compared with epoxy resin stone glue, marble glue has some shortcomings, such as low bonding strength, large shrinkage after curing, and brittle performance, so it cannot be used in the bonding of heavy-duty stone.

Marble glue has poor durability, aging resistance and temperature resistance, and is not recommended for long-term outdoor or tall buildings. In addition, the storage stability of marble gum is also poor, and the performance decreases with time. Therefore, it is necessary to pay attention to the factory date and shelf life when purchasing and selecting.

In recent years, the performance of marble gum using vinyl grease resin instead of unsaturated resin has been greatly improved, but it is difficult to be widely used in the near future due to ** reasons.

Stone bonding is also classified, for example, granite bonding has to use granite adhesive, marble is generally marble glue, there are many types, and generally these things are also very easy to buy, basically do stone accessories in the store will have, the actual situation can be found after the stone accessories store consult the shop owner.

The common one is marble glue, and many people use marble glue to bond the stone used for building decoration such as marble stone. Of course, there are also AB glue, such as some handicrafts, rare stones and the like will use AB glue.

Transparent crack repair glue is used in simple words, because it is transparent, it is used when sealing the crack, so that the repair situation inside the crack can be seen, and the crack repair situation can be judged.

The difference between transparent crack repair adhesive (Hummer) and general crack repair adhesive is that it is transparent, and the repair effect inside the crack can be seen, and it is still necessary to use it with joint filling glue and crack repair glue to achieve the best repair effect.

The visualization effect processing technology of crack sealing and filling of concrete structure can directly observe and measure the width, length, direction and other appearance shapes and dimensions of the cracks after filling, so as to intuitively judge (or infer the actual treatment length and actual filling effect) of the filling treatment, and can intuitively observe the future development and changes of cracks in the future project follow-up visits.
