How to see the quality of the cement base surface when making epoxy flooring

Low-strength cementitious. Epoxy coatings have lower substrate surface and bond strength than MPa, epoxy coatings occur after application, the lower part is not strong, and the forklift on the floor is lower. In the event of an emergency, a clasp is placed at the end of the paint. Coating.

2. Cracking of cement-based hollow and epoxy floor coating construction quality function. Such as hollowing, cracking and other abnormal conditions, in the pre-construction treatment of the surface, such as not treated, hollowing, cracking, hollowing, cracking, etc., will make the coating on a deeper basis coating.

3. The effect of the straightness of the cement base surface on the quality of epoxy resin floor coating. The flatness of the cement substrate is poor, and the coating thickness is difficult to maintain, which will affect the floor decoration effect on average.

4. The project of soft epoxy resin floor coating quality of cement-based surface. The fluffy surface of the cement-based surface will significantly increase the amount of primer and increase the cost of epoxy floor engineering coatings.

Moisture in the cement base, moisture in the emergency epoxy primer, construction quality function. Aquifer or substratum if wet, moist, moisture in the soil? After the pores rise to the surface, it plays a role in the coating layer, which directly affects the bond strength of the coating and concrete, which will make the coating blister, delamination, pinhole abnormality, so why do you need a waterproof and moisture-proof handle.

6. About the old paint cement affected by the quality of epoxy floor coating engineering. Usually we should first use a machine to ** the old paint, and then deal with the realization of the local unfavorable situation, while a hair on the ground, the old cement and sand layer, eliminate the unsafe oral and become a rough surface, to improve the adhesion of the cement-based new paint. Therefore, there is a lack of impact on the construction quality of epoxy floor coatings.

This lack not only makes the floor smooth and shiny, but also improves the service life of the epoxy floor coating.

It is distinguished according to the degree of dust and sand on the ground.

There is still a certain difference.

Epoxy flooring engineering construction steps:

1) Epoxy primer construction: 1. Ensure that the ground is clean before construction, and remove if there is any debris adhesion; 2. Mix the epoxy resin and the curing agent in the correct proportion. 3. If Zheng Qi stirs evenly, use the method of scraper or roller application.

4. It is required to be soaked to strengthen the adhesion. 5. After a dry solid, apply the epoxy middle coating.

2) Epoxy coating construction 1, before construction, it is necessary to ensure that the ground is clean, and if there is debris adhesion, it needs to be removed; 2. Mix the epoxy resin and the curing agent in the correct proportion, and add a certain amount of quartz sand according to the ratio; 3. After stirring evenly, dump it on the ground, and use a trowel to evenly open the material according to the thickness of the slag to increase the strength and impact resistance; Make the ground stronger and more compressive. 4. After the middle coating is dried and solidified, it is polished to polish the sagging objects and particles on the surface. 5. Dust is cleaned.

3) Epoxy putty layer construction 1, on the clean ground, the epoxy resin and quartz powder are stirred evenly according to the correct ratio, and the batch knife is used to evenly scrape on the ground to increase the combination between the middle coating and the surface layer, and further adjust the flatness of the ground; 2. Depending on the actual number of work needs, it is required to be smooth and without holes, and there is no batch of knife marks and sanding marks. Inspection method: make the ground completely flat without holes, and there is no batch of knife marks and sanding marks before the top coating can be constructed.

4) Epoxy surface coating construction 1, before construction should be kept clean, if there is debris adhesion to need to be removed; 2. Stir the B component of the topcoat material first; Then add the curing agent to mix and stir thoroughly; 3. Use rollers to evenly coat the material with which cloth; 4. After the coating is dry and solidified, the second surface coating is applied. 5. The artesian plane is coated with a trowel and scraped again.

The advantages of epoxy flooring over cement flooring lie in the following two points: 1. Good decorative effect: since epoxy flooring first entered China, everyone is interested in its decorative effect, and the color adjustability is very strong, and the owner can adjust the color according to his personal preferences.

In addition, its flatness and mirror effect can also enhance the company's corporate image. Now many public places, schools, kindergartens floor puzzles can be seen, its decorative effect has been recognized by various industries in the domestic market.

Good stability and long service life: epoxy flooring has good performance in waterproof, anti-corrosion and anti-fading, and its effect of abrasion resistance, acid and alkali salt and other chemical reagents is also very good. The flooring company can set up different types of flooring construction plans according to the different industries of the owners to achieve the longest service life.

According to the ground conditions, for uneven ground, it is recommended to make mortar and paint epoxy putty layer. Here's how:

1. To do epoxy flooring, the first thing is to polish and vacuum, use a dust-free grinder for overall grinding, and then use professional cleaning tools to clean the ground. If there is paint and greasy floors, remove the greasy floors thoroughly.

2. Match the primer, and use a high-permeability primer (the primer and the curing agent are mixed, the ratio is 2:1) to paint the bad ground, and if necessary, you can also paint the primer twice. After drying, the next process is carried out.

3. Make a mortar layer: mix the solvent-free medium coating (the solvent-free medium coating and the curing agent are mixed, the ratio is 4:1, the film is formed at one time, and the hardness is large), then add quartz sand, and then fully stir, and finally paint the mortar layer.

Two coats of mortar can also be applied if required. The main function of the mortar layer is to level the ground and play the thickness.

4. Make epoxy putty layer: prepare the solvent-free primer (the solvent-free primer and the curing agent are mixed, the ratio is 2:1, and the powder is added after stirring), and then the epoxy putty layer is painted, and two putties are painted.

The effect of putty is to close the tiny holes left by the mortar layer. After drying, it will be sanded and vacuumed.

5. Make epoxy topcoat layer: Epoxy topcoat and curing agent are mixed, the ratio is 2:1, and then roller coating is carried out after stirring. If you do epoxy self-leveling, you need to scrape it with a trowel, automatically level, and then apply the varnish self-leveling after drying, and the ratio of varnish self-leveling plane paint and curing agent is: 1.

You can choose to use a matte overcoat topcoat, and the uneven ground will not be obvious. It's okay not to do leveling mortar.

The uneven ground can also be done, that is, it takes more work to polish, if the full polishing can not meet the requirements, then it will increase the material, thus appropriately increasing the cost.

Of course you can, but you can only do it smoothly.

This blank can be made on the ground, but the price is high.

How uneven are you? Not all unevenness can be smoothed

Leveling, grinding on it.

You can level the ground first and then do epoxy.

Yes, you can do epoxy.

It depends on what the ground is and how hard it is.
