What needs to be paid attention to to ensure the construction quality of epoxy flooring

To ensure the construction quality of epoxy flooring, it is necessary to pay special attention to three major links, which can be summarized as pre-construction design and professional construction team; Understanding of the construction ground and surface pretreatment; Construction organization and quality supervision.

1. Pre-construction design and professional construction team. This is the primary factor and important link to ensure the construction quality of epoxy flooring, including the selection of floor functional range, the use of coating system and the design of construction organization, etc., which requires construction personnel to choose the appropriate materials, processes and costs after comprehensive communication with customers.

2. Understand the construction ground situation and pretreatment of the ground. It is necessary to obtain information related to the construction ground from various aspects, and then formulate a detailed surface treatment plan. The key factor of floor coating is the treatment of the base surface, so it is the main factor to ensure the quality of floor construction.

3. Correct construction organization and strict quality supervision. Under normal circumstances, epoxy floor construction is the last procedure of foundation engineering, which generally has more requirements, tight construction period, higher requirements, more limiting factors, and if there is no reasonable construction plan, it will have an impact on the construction period. Moreover, if the operation is not in accordance with the specifications, the quality cannot be guaranteed, so the technical personnel should confirm the relevant projects before construction and do a good job of recording.

After the construction is completed, the site will be handed over to the customer and the maintenance method will be reminded.

First, the plain land treatment.

1. The basic surface is subject to the cement powder surface or grinding stone;

2. The plain land needs to be maintained for more than 28 days, and the moisture needs to be less than 8% before the construction of the plain land, if there is unevenness or hollowness, it needs to be removed;

3. Fill the ground with epoxy mortar;

4. The oil stain of the plain land needs to be cleaned thoroughly;

5. Before construction, it is necessary to keep the construction site dry and clean.

Second, the bottom coat.

1. Before construction, it needs to be kept clean, if there is any debris adhesion, it needs to be removed, and the main agent and hardener should be mixed according to the correct ratio and fully stirred;

2. It is necessary to adjust the appropriate viscosity and mix according to the ground conditions, and the construction of the completed materials should be completed within 4 hours;

3. The curing and hardening time of the bottom coat is about 8 hours.

3. Medium coating.

1. Before construction, it needs to be kept clean, if there is debris adhesion, it needs to be removed, and the main agent and hardener should be mixed according to the correct ratio and fully stirred;

2. Add an appropriate amount of mixed epoxy resin to quartz sand;

3. Use a trowel to evenly coat the material;

4. The construction of the mixed materials should be completed within 30 minutes;

5. Do a good job of handover at the construction handover.

The curing and hardening time of the medium coating is about 8 hours or more.

Fourth, the batch of soil layer.

1. Mix the main agent and hardener according to the correct ratio and stir thoroughly;

2. Use a batch knife to evenly coat the material;

3. The construction of the mixed materials should be completed within 30 minutes;

4. The curing and hardening time of soil is about 8 hours or more;

5. According to the actual needs, the construction of several roads is required to be smooth and without holes, and there is no batch of knife marks and sanding marks.

5. Topcoating.

1. Before construction, it needs to be kept clean and removed if there is any debris adhesion;

2. Stir the main agent well before use;

3. Mix the main agent and the hardener according to the correct ratio and stir thoroughly;

4. Use a roller or trowel to evenly coat and mix the material, and the construction of the material should be completed within 30 minutes;

5. The construction handover should be handled at the handover place;

6. After the construction is completed, you can get on the person after 24 hours, and you can be under heavy pressure after 72 hours (subject to 25).

The epoxy floor of the factory workshop is mainly for the appearance and improvement of the working environment of the factory workshop, so as to achieve green environmental protection, reduce the role of dust and ground moisture, the most commonly used epoxy floor paint on the floor of the factory workshop are: thin coating floor paint, epoxy self-leveling, epoxy anti-static floor, corundum wear-resistant floor, heavy anti-corrosion floor, etc.

Epoxy flooring is a kind of high-strength, wear-resistant, beautiful flooring, with no joints, solid texture, good chemical resistance, anti-corrosion, dust-proof, easy maintenance, low maintenance costs and other advantages.

However, the choice of epoxy floor paint on the factory floor floor is not something that can be done if you want to, you need to pay attention to the following points:

1. Whether the floor of the factory workshop meets the construction conditions of epoxy floor paint.

The factory workshop is not what you think can be constructed with epoxy floor paint, and the floor paint manufacturer is required to conduct ground surveys in the early stage to detect the moisture content, flatness, and strength and hardness of the existing ground. For the ground moisture content higher than 6% to carry out drainage treatment, flatness is not enough need to be polished, sand and ash is very serious is recommended to redo concrete, and then the construction of epoxy floor paint.

2. Whether epoxy floor paint can be used in the factory workshop.

Epoxy floor paint can be used on the factory floor! However, the workshop floor of different factory properties should choose to use suitable floor materials, and choosing the right one can avoid many external factors. Epoxy floor paint manufacturers suggest that for the factory workshop that requires a high degree of cleanliness, you can choose epoxy self-leveling floor, for the ground is just a dustproof person, you can choose an economical and practical epoxy flat floor, and the ground requires wear-resistant and compression-resistant and forklift walking, it is recommended to choose epoxy mortar floor, if you require anti-static, you can use epoxy anti-static floor.

3. Whether the on-site environment of the factory workshop meets the construction requirements.

The use of epoxy floor coating in the factory workshop takes time to solidify and form, so there are strict requirements for temperature and humidity, and the temperature is too high and too low, and the humidity is too large to properly delay the construction to avoid the quality of the floor caused by this problem. In addition, the construction site of the factory workshop needs to be closed to avoid dust and debris falling on the surface of the paint film and affecting the construction effect of epoxy floor paint.

4. The maintenance work after the epoxy floor paint is done in the factory workshop.

The epoxy floor paint in the factory workshop generally cannot be put into use immediately after the epoxy floor paint, and it needs to be cured for 7 days, and during the curing period, water or other solutions should be avoided from infiltrating the surface.

1. The construction site of epoxy floor should ensure good ventilation conditions, which can quickly and effectively discharge the harmful gases generated during the construction process to avoid poisoning by inhaling harmful gases for construction personnel;

2. Before construction, the ground on the site should be polished to maintain the flatness of the ground. At the same time, the ground dust should be cleaned regularly, so that the application effect of epoxy floor will be better;

3. The construction personnel should wear masks and goggles when carrying out construction, and wear special protective clothing for construction to avoid the paint splashing on the first or eyes during the construction process.

4. The coatings, adhesives and other flammable materials of epoxy flooring should be stored away from the fire source or high temperature area, and ensure the dryness of the environment, and do not smoke or use open flames at the construction site.

5. If there are special circumstances in some places and it is necessary to carry out operations in the process of construction, it is necessary to set up an isolation area with sufficient space to prevent dust, gravel, etc. from seeping into the ground under construction.

6. During the completion of construction, the construction personnel need to maintain the ground regularly, and clean up the ground in time if there is coarse hard gravel and dust, which can prolong the service life of the epoxy floor and reduce the wear and tear of the ground.

Safety precautions for epoxy floor construction:

1.In the process of epoxy floor construction, many equipment uses electricity. Electricity needs to be safe, so this is a big safety hazard.

2.Paints are organic and can be burned in the city, so attention should be paid to electric sparks and workers' cigarette butts during construction. Eliminate the potential danger of fire.

3.Solvents are all containing volatile gases, which are very prone to gas occurrence when they encounter sparks when they reach a certain concentration in the air.

4.Most of the materials and adhesives of floor coatings contain volatile and toxic gases, and workers will have poisoning symptoms and prevent poisoning when working in such an environment for a long time.

5.During construction, improper use of tools and machinery can cause harm to workers.

Safety precautions for epoxy floor construction:

Such as: fire prevention.

Flooring materials, adhesives, and other flammable materials should be stored away from fire and kept dry.

Fireworks are strictly prohibited on the construction site.

For example, to prevent the hazards of toxic gases and chemicals.

Flooring materials and adhesives for painting should be stored in an airtight manner.

On-site construction personnel should wear work clothes, masks, and goggles to avoid materials splashing into their eyes.

It is strictly forbidden to eat and live in warehouses and construction sites where toxic chemicals are stored.

For a large area of epoxy floor paint construction site, it should be worked in turns, so that the construction personnel can rest in the air circulation.

Such as: to prevent other existing safety hazards.

Measures to prevent falls from working at height.

It is strictly forbidden for construction personnel to work after drinking a large amount of alcohol.

Lighting of sufficient brightness should be ensured during night construction.

Floor construction equipment and tools are safe to use electricity, and pay attention to the inspection of lines.

In summer, attention should be paid to heat prevention, and special attention should be paid to not constructing in a high temperature and humid environment, which does not guarantee the quality of the project and damages the body.

In winter, the ambient temperature of the construction site should be ensured to prevent safety accidents caused by excessive wear and inflexible operation of workers, which will affect the quality of construction.

Whether it is a flooring enterprise or a flooring construction unit, a large team or a small team, each flooring project will do its best to pay attention to the details of every epoxy flooring construction safety precautions, and strive to do a good job in the project, so that they are satisfied, so that the owners are satisfied, and a win-win situation is formed.

Focus on R&D and production of floor construction materials, integrating R&D, production, sales, engineering design and construction and after-sales service. There are epoxy floor coatings, parking lot floor coatings, concrete sealing curing agent hardening, anti-static floor coatings, acrylic courts, PU courts, color sealing curing agents, wear-resistant floor coatings, dust-free workshop purification systems, etc. Provide flooring engineering solutions and construction services for factory workshops, underground garages, sports fields, commercial municipal, etc.

Precautions for epoxy floor engineering construction:

1. Environmental requirements:

1) The construction base surface should be kept clean and dry, no other engineering construction cross operations, the relative humidity of indoor air should be less than 85%, and the construction should be stopped when the humidity is too large.

2) Construction temperature: 5, if you want to construct in 5, choose a special formula. Humidity is recommended to be below 75%.

3) Ensure air circulation during construction. When modulating the dosage, it should not exceed 30 minutes.

2. Check the materials:

It is necessary to strictly inspect and configure the epoxy floor paint materials used, and all incoming materials must be inspected to prevent the use of unqualified products.

3. Select Tools:

It is necessary to use high-quality rollers, spray guns, paint brushes, masking paper and other tools and auxiliary equipment to avoid quality problems caused by poor tools.

4. Clean the base surface

While grinding the base surface with a motorized grinder, it is necessary to use a manual grinder to remove the base surface that needs to be cleaned thoroughly.

After the construction of the epoxy primer, the base surface must reach more than 80% of the primer solidification coverage, if it does not meet the standard, the epoxy primer needs to be constructed.

5. Clean the substrate:

After cleaning the base surface, the substrate should be checked for cracks, empty shells, if there is, it must be deeply cut and cleaned with epoxy resin mortar to fill, and because the epoxy resin does not allow water, it can only be dry in the treatment process, and can not be brutally beaten when cleaning so as not to knock on the base layer on the loose edge.

6. Epoxy resin primer coating

At the same time of the treatment of the substrate, epoxy primer and coating can be carried out, and the balance between the construction progress and the materials needs to be grasped during the construction of the ingredients, and the material should not be cut too much at one time, so as to ensure that the material is still in line with the usable time when coating, and it is brushed before gelling, so that the material maintains good permeability and ensures the bonding performance.

After the epoxy mortar layer is constructed, it should reach a flat state, and there can be no potholes; The epoxy putty layer should seal the capillary holes of the mortar layer; When sealing the topcoat of epoxy floor paint, it is necessary to achieve uniform color and no capillaries before painting.

7. Do a good job of maintenance during the construction process to avoid the invasion of dust and sundries, which will affect the paint effect.

The surface should be free of oil stains, sundries, and no obvious leakage.

Keep the surface of the coated object clean, and the moisture content of the coated material must be less than 7%.

8. The concrete strength must be C25Contains more than 350kg m3 of ordinary Portland, cement and water-cement ratio <. The deviation of the flatness of the base layer should be less than 2mm. The moisture content of the base layer should be less than 8%.

9. In the design of coating formula, it should be noted that pigments that can react chemically with resins or additives should not be used. It is strictly forbidden to mix two different types of paints without testing.

10. After the construction is completed, it needs to be maintained for at least 7 days before it can be put into use. During the curing period, there should be no infiltration of water or various solutions.

Epoxy floor construction precautions: pay attention to the environmental requirements of coating construction, the construction base surface should be kept clean and dry, no other engineering construction cross operations, indoor air relative humidity should be less than 85%, when the humidity is too large should stop construction.

Each layer should also be polished after drying, otherwise the situation above will also occur. Pay attention to the construction, do not cross the construction, so as not to affect the quality. The paint should be stirred well, and each layer should be dried before the next process is done to avoid problems such as blistering.

Epoxy floor construction process steps of the base surface cleaning: at the same time as grinding the base surface with a motorized grinder, it is necessary to use a manual grinder to remove the base surface that needs to be thoroughly cleaned.

Epoxy floor construction process steps of cleaning and inspection of the substrate: when the base surface is vacuumed clean, the substrate should be checked for cracks, empty shells, if there is, it must be deeply cut and cleaned with epoxy resin mortar filled, and because the epoxy resin does not allow water, it can only be dry in the treatment process, and the cleaning can not be brutally beaten so as not to knock on the bottom layer on the loose edge.

Epoxy resin primer coating of epoxy floor construction process steps: epoxy primer and coating can be carried out while the substrate is treated, and the balance between the construction progress and the material needs to be grasped during the construction batching, and the material can not be cut too much at one time, so as to ensure that the material is still in line with the usable time when coating, and is brushed before gelatinization, so that the material can maintain good permeability and ensure the bonding performance.
