What to pay attention to in floor construction Everything is customer oriented

1. Ground pretreatment 1Effectively remove oil, dust, sand, moisture and other foreign substances from the cement floor. 2.

Using a grinder or other tool, remove the exposed wire and concrete surface, then use Epoxy Mortar to level the part. 3.If necessary, use a sandblaster to scour away the rough sand particles on the surface.

4.Grouting treatment. 2. Pre-coated (CD-10) surface resistance:

104ω~105ω。1. After the main agent and the curing agent are fully stirred at a ratio of 2:1, use a roller or brush to coat 1 2 times.

In order to strengthen the bonding strength, add 10 20% epoxy primer before use After the room temperature is 20 for 5 to 6 hours, the operator must wear shoes for sanding. 3. Use electric fans or other ventilation equipment during construction,...

Precautions for epoxy flooring construction site:

1. Construction site requirements:

1. The structural concrete must have a strength of more than C20, the surface is smooth and there is no sanding, the curing period after pouring reaches 28 days, and the surface flatness requires 2m to measure 3mm by a ruler.

2. The moisture content of the concrete floor is less than 8%, the air humidity is less than 80%, and the construction temperature is the most suitable at 20-25 C, and the construction must be postponed below 5 C.

3. The first layer of the concrete structure of the building plant needs to be treated with moisture to avoid the first layer of epoxy floor being affected by water vapor and blistering and delamination.

Second, pre-construction requirements:

1. Before construction, calculate the amount of materials according to the construction area, prepare the construction materials, and select the batching area according to the construction area, path and direction.

2. The batching area is first padded with a layer of plastic cloth, and then covered with a layer of cardboard to prevent the material from dripping and polluting the base surface.

3. Prepare the tools required for ingredients.

3. Construction site arrangement:

Set up a project leader, technical monitor, and safety supervisor at the construction site, and arrange the construction team according to the construction requirements. Construction personnel must comply with on-site rules and regulations.

Fourth, material storage:

All admission materials are placed in the designated area according to different categories, and a special person is set up for safekeeping, and the subcontractor can sample and test the materials, and the construction is strictly in accordance with the design amount.

Fifth, construction ingredients:

The construction materials are batched by special personnel, in strict accordance with the material requirements, and the batching area is paved with plastic steps to avoid the material from polluting the base surface. Waste or other garbage is sent to a designated area for disposal and discharge.

6. Air cleanliness requirements in the construction area:

The construction area should be closed and irrelevant personnel should be prohibited from entering, and cross construction is strictly prohibited. The air cleanliness meets the general cleanliness requirements.

7. Safety matters:

1. Construction materials should be placed in a cool and closed place, and obvious signs should be set up in the placement area, and close open flame operation is strictly prohibited.

2. The material storage area is equipped with fire extinguishing safety facilities.

3. A special person is responsible for the storage of materials, and the on-site safety supervisor is responsible for supervision.

8. Epoxy floor use protection:

1. The epoxy floor can only be used after the completion of the curing period.

2. It is strictly forbidden to have any heavy objects collide or be scratched by sharp objects during the use period.

3. There shall be no serious corrosive items sprinkled on the subfloor in the area without special chemical resistance requirements, so as not to cause damage to the epoxy floor. The entire area should be cleaned periodically to ensure an aesthetically pleasing surface.

Flooring is made by a variety of flooring construction processes such as mixing, dissolving, and dispersing various kinds of substances. It is mainly divided into decorative flooring, high anti-corrosion flooring, heavy-resistant flooring, etc. The floor has the characteristics of bright, real, beautiful, wear-resistant, waterproof, anti-corrosion and prudent.

Let's talk about the precautions in the floor construction process.

Precautions for floor construction process: The strength of concrete is ordinary silicate above c kg m 3. The ratio of cement to cement <;

During the construction process, the tiling layer must be fine stone concrete and its thickness must be less than 50mm.

1. The construction of wear-resistant materials and the irrigation of cement floors are generally carried out at the same time, in order to ensure the construction quality of the wear-resistant layer and the progress of the project, the mixed water irrigation must be matched during the horizontal construction process.

2. The design of the template should be flat and firm, the template should be 6m as the best, coated with release oil, and the template should be measured at any time with a leveler, and the deviation must be adjusted in time.

3. The floor construction process needs to use heavy-duty steel long rollers (steel rollers are larger than the template) to repeatedly exert pressure to keep the steel model clean and the floor flat.

4. During the floor construction process, use a hose to secrete water for the parts with serious water secretion;

5. During the construction process of Party B's floor, no cross construction shall be arranged, the constructed floor shall be protected and protected, and Party A shall provide tap water and electricity.

1. The cement base used in the floor construction process should be firm and strong, and the wide trace collapse should not occur without shelling, and the phenomenon of gray shell should be eradicated, and it is best to pour the concrete layer and the mortar flat layer together. First of all, a concrete layer should be formed, the thickness of the mortar layer should not be less than 4 cm, and the fork lane is required to be thicker.

2. The floor construction process requires no sand and dust on the surface, good hardness, and no cement powder. a. High-quality cement is required. b. The mortar layer of the newly poured cement must be fully maintained.

3. The cement base surface is flat, not concave and convex, honeycomb pockmarks, cement blocks.

4. The flatness of the ground is not greater than the thickness required by the coating (according to the 3-meter ruler).

5. The surface is dry and the water is insufficient.

6. After the floor construction process is completed, the ground should be kept dry to avoid oil pollution. Remember that after the maintenance period of the cement floor, it is not allowed to rinse or mop water with water for 5 days before entering the venue.

Five key points of epoxy resin floor construction:

First, the plain land treatment.

The basic ground is subject to cement powder smooth surface or grinding stone ground;

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

leveling the ground with epoxy mortar;

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

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

Second, the bottom coat.

Before construction, it needs to be kept clean, if there is debris adhesion, it needs to be removed, mix the main agent and hardener according to the correct proportion, and stir it fully;

It is necessary to adjust the appropriate viscosity and mix according to the ground conditions, and the construction of the material needs to be completed within 4 hours;

The curing time of the undercoat is about 8 hours or more.

3. Medium coating.

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

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

Use a trowel to evenly coat the material;

The mixed materials need to be completed within 30 minutes, and the construction is completed;

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.

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

Use a batch knife to evenly coat the material;

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

The curing and hardening time of soil is about 8 hours;

Depending on 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.

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

Stir well with the main agent before use;

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

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

The construction handover should be handled at the handover place;

After the construction is completed, it can be put on the person after 24 hours, and it can be pressed after 72 hours (subject to 25, and the opening time should be moderately extended at low temperature).

The construction of floor paint is divided into three stages: before construction, during construction and after construction, and the problems that need to be paid attention to in each time period are as follows: 1. Preparation before construction

1. Check whether the ground is flat, and mark the ground that is too high or too low for polishing and repair. We generally use a 2m straight ruler to measure and record the gap difference. 2. Before construction, it is necessary to understand the maintenance time of the clear surface, whether the waterproof layer at the bottom layer is under construction, and what the weather is during construction.

Because epoxy flooring is not suitable for construction in a cold or humid environment, generally speaking, 7 days of maintenance time is suitable in summer, and 10 days if the weather is cold and humid. The detection of water content is to prevent too high water content from affecting the adhesion of the coating film after construction. 3. In order to prevent the defects of coating film such as sand and hollowing after construction, we generally check the strength of concrete before construction.

For concrete with poor strength, special attention should be paid to vacuuming before construction, and then the solvent-free primer should be diluted for priming to make the concrete stronger. 4. Check whether the construction environment is clean and closed. If there is no closure, the dust will blow into the construction ground, making the ground granular and uneven.

In addition, it cannot be applied in a super-cold environment, so as not to affect the coating effect. 2. During construction: 1. The amount of material ratio should be accurate, and the material should be stirred evenly.

2. During construction, the thickness of the coating is uniform, and it can only enter the next process after solidification. 3. Check whether there is a quality problem on the coating surface after construction after each coating, and deal with it in time. 4. Pay attention to maintaining the hygiene of the construction environment and avoid dirt falling into the uncured coating.

3. After construction: 1. After the construction of the floor paint coating is completed, clean up the site and take all the construction tools and materials away from the site After curing for hours, the surface coating film can be cured and can be walked, inspected after three days, and can be put into use after a week. 3. After being put into use, the epoxy floor project should pay attention to maintenance, prohibit destruction, regularly check the surface condition of the epoxy coating, and report for repair in time if there is damage.

Floor paint construction notes: 1. Check the foundation ground condition: whether it is smooth?

Identify the areas that are too high or too low, and polish or repair them. 2. It is necessary to clearly know the maintenance time of the ground, the situation of the construction environment, temperature, humidity, whether there is a waterproof layer, etc. Because the construction of epoxy floor code Lushengping paint is affected by the environment, the temperature can not be too high or too low, and the humidity should also be within the appropriate range.

The maintenance time is 7 days in summer and 10 days in places with low temperatures or humidity. Check the strength of the concrete floor. This is to prevent undesirable phenomena such as sand and hollowing of epoxy floor paint after construction.

Concrete ground with low strength, special attention should be paid to vacuuming before construction, after cleaning, paint with epoxy sealing primer, seal the capillary pores of concrete floor, prevent water vapor, debris and so on from penetrating into the ground, enhance the strength of concrete floor. Check whether the environment of the construction site is clean. If the epoxy floor paint is mixed with dust and other debris, the epoxy floor will appear granular or uneven.
