Who has a lot of experience in the crack treatment of epoxy flooring?

Epoxy resin floor is generally used for non-rigid flooring, generally not used alone, and more used is to incorporate a certain powdered aggregate or strengthen it with glass cloth. If cracks occur, the reasons are: first, the settlement of the foundation floor (no expansion joints); The second is to add excessive coagulant when blending epoxy.

In the first case, cracks will continue to occur after a simple repair. The repair method is generally to use a thinner epoxy to fill the joint, try to let him penetrate more, and then repair it with the same ingredients as the original ground after the surface is cured.

Ordinary cracks.

Pre-bake epoxy A B and material at 60-70 degrees for 15 minutes to see whether quartz sand (pre-baked) is added to the size of the cracks, and the preparation is ready to be repaired.

First of all, we must know that epoxy floor paint will not crack, the source of cracking is the cracking of the foundation ground, if the original foundation ground itself has cracks, and the ground cracks are not cut and repaired in the process of construction, so that there may be traces of cracks after the construction is completed.

If the foundation of the ground itself is not cracked, and the epoxy floor paint will crack after a long time, this is because the natural settlement and natural cracking of the foundation ground will stretch the ground, so that the epoxy floor paint on the surface will crack. So how to prevent cracks from appearing, we need to do a good job of grassroots treatment.

After the epoxy floor paint is done on the ground, as long as the ground itself does not produce cracks and does not need to be bumped by heavy objects, the floor paint will not produce cracks.

After the floor is finished with epoxy floor paint, there will generally be no cracks, and the floor itself will not have cracks, but if there are cracks in the future, it is easier to appear.

If the base layer is clean, the ground is stable, solid, and evenly painted, there will be no cracks

The epoxy resin floor should be leveled before the production of the floor, which is the key to prevent cracking and peeling after the epoxy resin floor, and the normal epoxy floor will not produce cracks, mainly because the protection is poor, and hard things will scratch the ground.

After a period of time after the completion of the construction of epoxy flooring, there may be cracks of different degrees, which affect the appearance very much, and there is an obstacle to the use, and the cracks are mainly structural cracks, expansion cracks, stress cracks, creep cracks, construction joints, etc.

This depends on whether the foundation surface is deformed. There will be no cracks in the ground without subsidence.

Will there be cracks after the sun floor? There will be no cracks in the ground after the foreign place name is done, because this floor machine is very good.

Ground cracks are generally caused by the stress of the cement floor. Solution: Clean the floor paint at a distance of 250px on both sides of the crack.

Check the crack situation, cracks larger than 3mm can be directly poured (cracks more than 25px can be filled with some fine sand, reserve about 4mm), such as cracks less than 3mm need to be expanded to more than 3mm. Then clean up the debris and dust in the joints.

Before epoxy construction, the expansion joint can not be filled, we can polish the ground, use the wire hook to remove the debris in the expansion joint, when the roller coats the epoxy primer, let the primer flow naturally, and then fill it with putty when scraping and closing, and wait for the epoxy topcoat to be applied, and then use the cutting machine to cut out the expansion joint in the original position, and then repair the glue.

If the foundation of the ground itself is not cracked, and the epoxy floor paint will crack after a long time, this is because the natural settlement and natural cracking of the bottom surface of the foundation will stretch the ground, so that the epoxy floor paint on the surface will crack. So how to prevent cracks from appearing, we need to do a good job in the ground base treatment and responsible construction, and also hope that peers in the industry can make high-quality floors.

Summary. Hello dear, cracks in the indoor floor have a great impact on the epoxy resin floor paint. Fine cracks on the surface of concrete, also known as mesh cracks and cracks, are very common on the surface of concrete, but this crack has a great impact on the epoxy floor.

This crack does not affect the strength and structure of the concrete, but it can seriously affect the aesthetics of the ground. There are three characteristics of fine cracks, the first is that their depth will not exceed 3mm; The second is that the shape of the crack is generally hexagonal; Third, fine cracks are formed in the early stages of concrete. There are many reasons for the formation of fine cracks, the most common being due to improper construction.

For example, the construction environment temperature is high, no slow evaporation agent is used or the surface trowel forms a large pressure to cause the aggregate to slide, and the surface mortar is too much to produce cracks; An increase in the water-cement ratio will lead to cracks.

Fine cracks on the surface of concrete, also known as mesh cracks and cracks, are very common on the surface of concrete, but this crack has a great impact on the epoxy floor. This crack will not affect the strength and structure of the concrete of the hailstone, but it will seriously affect the aesthetics of the ground.

There are three characteristics of fine cracks, the first is that their depth will not exceed 3mm; The second is that the shape of the crack is generally hexagonal; Third, fine cracks are formed in the early stages of concrete. There are many reasons for the formation of fine cracks, the most common being due to improper construction. For example, the construction environment temperature is high, no slow evaporation agent is used, or the surface is wide and the surface is wide and the trowel forms a large pressure to cause the aggregate to slide, and the surface mortar is too much to produce cracks; An increase in the water-cement ratio will lead to cracks.

Once there are obvious cracks in the floor paint belt bench floor construction, the cracks will gradually expand and become longer and longer in the future use process. This change will directly affect the coating of epoxy resin floor paint, which will eventually lead to cracking and warping of epoxy floor paint.

1. Generally, an expansion joint needs to be arranged during construction, and if the floor paint is cracked, use the retained expansion joint, and use elastic polyurethane to fill it. 2. If it is a temperature stress crack, use a cutting machine to cut a V-shaped crack, and then embed the steel sheet into it, and then add quartz sand to the floor paint to fill it in. Recommended Considerations:

1. Cracks appear during construction, even if they are repaired, the cracks will slowly extend after a long time, and sometimes they will be directly displayed to the coating of epoxy floor paint, resulting in cracks in the epoxy floor paint. 2. During construction, we must pay attention to the temperature difference, the temperature difference of the weather and the temperature difference between the inside and outside of the concrete is too large or the temperature difference caused by other reasons is also an important reason for the occurrence of cracks. 3. When repairing again, you need to add some quartz powder to the epoxy floor and stir it well, apply it around the crack mortar, and then wait for a while to paste the cut fiberglass cloth on the surface, and then gently remove the bubbles, do not let the fiberglass cloth wrinkle and do not leave bubbles.

Finally, brush another layer of floor paint on the fiberglass cloth, and then paste two layers of fiber cloth.

Introduction to the renovation of the old epoxy floor: The renovation of the old floor refers to the ground after a certain period of use through a series of construction treatments, so that the ground is refreshed or the original ground is changed, and the ground has a new use effect. It is suitable for industrial flooring, commercial flooring and special flooring.

Scope of application of old epoxy floor renovation: The old ground renovation is suitable for ceramic tiles, stone, cement floor sand and ash, terrazzo floor, wear-resistant floor, epoxy floor, polyurethane floor, cement self-leveling, PVC floor and other ground materials. It is widely used in plant floor, workshop floor, logistics, warehousing, supermarkets, stores, shopping malls, exhibition halls, 4S stores, parking lots, airports, waiting rooms, hospitals, computer rooms, canteens and other places.

The advantages of the latest old epoxy floor renovation materials: easy construction, fast and no or only a short shutdown; Tough and wear-resistant, reshaping and efficient strengthening flooring; It can be partially replaced, which is economical and practical; Multi-color selection to create a beautiful workshop floor environment; The traditional way of renovating and transforming the old ground, the methods of renovating and transforming the ground in different places and different materials are not the same, and there are generally the following ways: polishing and renovation:

Through mechanical and abrasive grinding, the ground is exposed to a new surface, and at the same time, the surface protection treatment is supplemented to achieve the effect of renovation. This method is usually suitable for tiles, stones, concrete, terrazzo, wear-resistant floors and other floors with whole materials. Lifting Floor Renovation:

As the name suggests, it is to use a series of construction methods to further improve the ground transformation of the original industrial workshop and achieve a higher degree of use and decoration requirements. For example, concrete floors, wear-resistant floors, and terrazzo floors are transformed into concrete sealing and curing agent floors through construction, which is a typical lifting type renovation.

Coefficient of friction of the old ground renovation agent floor (bright but not slippery) Comparison of the friction coefficient of a mechanical plastered sample treated with an old floor renovation agent with a standard brick (the higher the value, the less slippery it is): according to ASTM C 1028, the friction coefficient of a standard brick on dry and wet surfaces is and respectively; The coefficient of friction of mechanical wipe samples treated with old ground refurbishment treatment agents on dry and wet surfaces is and respectively. Old Floor Renovation Treatment Agents Increase Adhesion:

ASTM-D3359: The adhesion between the floor and epoxy resin is increased by 17 and the adhesion is increased by 28% in the presence of water vapor; The adhesion to polyurethane remains unchanged.

Use professional epoxy resin grinding equipment to remove all the old epoxy resin floors, and you can construct various types of epoxy resin floors according to the actual situation. If there is oil stain on the original epoxy old floor, you can use a special degreasing material to scrub the oil stain and degreas, degreasing and deoiling, 2-5 times in a row. After one day of observation, after the surface is free of oil stains, various types of epoxy flooring can be constructed according to the actual situation.

If it is found that the original old epoxy resin floor has local potholes, you can first use professional epoxy grinding equipment to polish the original old epoxy resin floor, use tools to remove the surface layer of the cement floor with hollows, and then use professional high-strength cement or special epoxy repair mortar to repair and level the position of the floor with potholes, when the pothole floor is repaired, you can construct various types of epoxy resin floors according to the actual situation.

No thing is perfect, and for epoxy floor paint, it is not perfect, and there will be small flaws, and it is okay to pay attention to these details. For example, the topcoat of floor paint softens and expands the paint film of the primer, and even bites up and detachs and produces wrinkles and blisters. Today, let's take stock of the problems and solutions of epoxy floor paint.

First, the problem. 1. There are many epoxy floor coating manufacturers who do not pay enough attention to the construction application technology because they do not directly construct the coating, and do not study the construction technology of the coating, so they do not have the ability to publicize and promote their distributors and engineers;

2. The specialized paint coating construction industry has not yet been formed, and the scale of the enterprise is small and few, and it is impossible to adopt advanced construction technology and means;

3. The market is not standardized enough, there are short-term behaviors, and there is not enough attention to the quality of coating, and it is impossible to give priority and high price, which frustrates some construction enterprises for advanced construction technology and equipment.

4. The owner has less expertise in coatings and coatings, and cannot distinguish what is good and what is bad.

Second, the solution.

1. Manufacturers of paint production should pay attention to construction application technology, strengthen research on the construction technology of coatings, and publicize and promote advanced construction technologies and means for their distributors and engineers to ensure the quality of construction. Set up a service center to provide technical advice, painter training programs, program recommendations, etc., to enhance the awareness of after-sales service;

2. Industry associations formulate strict industry standards, and carry out publicity and supervision to promote the standardization and healthy development of the coating industry;

3. Construction enterprises should actively adopt advanced construction technology and equipment, seize the opportunity to develop in the direction of specialization and scale, improve competitiveness and expand competitive advantages. Paint needs professional construction to reflect its effect, in a sense, the quality of the coating three points depends on the paint seven points depends on the construction, if the paint does not use advanced construction technology will not get excellent results, on the contrary, if the general paint using advanced construction chain reputation process can make up for some of the lack of paint quality itself.

Summary. Hello dear, happy to answer your <>

Cracking of epoxy floor paint is mainly caused by aging, and generally speaking, expansion and contraction, wet and dry surface temperature changes are the result of thermal expansion and contraction. In the process of laying the floor, it is necessary to choose suitable resins and plasticizer pigments, etc., plasticizers or plasticizers can soften the coating, so that the layer is more elastic and reduces the reaction due to climate and temperature changes. In fact, the cracking of epoxy floor paint is also related to the formula, which is not a surface problem, but caused by the damage of the entire layer.

Just three months after the shop, the cracks were bulging.

It is the result of thermal expansion and contraction due to temperature changes on the surface such as expansion and contraction, wetting and drying, etc., due to aging.

It will age in three months.

It can also be caused by poor quality and thermal expansion and contraction.
