It is an ideal floor coating for all kinds of industrial enterprise plants to meet ISO9000 series international quality standards and commercial, hospital, school, office, etc.

For concrete floor polishing, it is necessary to use Nalut Lithium Nail Sealing Hardener and Nanote Lithium Concrete Sealing Hardener, and then polish it to make the concrete floor have an excellent polishing effect. Concrete is polished in a series of steps, culminating in the use of 30-1000 mesh diamond grinding discs. Each step in the process improves the gloss and reflectivity of the concrete floor.

But there are other options, and although the concrete floor is not polished with 30-1000 mesh diamonds, it still has a beautiful appearance.

A two-step grind is obtained to obtain an exposed aggregate, and then a Nalut lithium-based concrete sealant is applied to the concrete floor, which can be referred to as exposed stone, the appearance of the seal. Although the concrete floor acquires a beautiful polished decorative appearance, this polish is still beautiful as a result of applying topical paints, but requires more surface maintenance.

As for the polished concrete floor construction process? Let's take the construction process or construction method of Nalut concrete sealant curing agent floor polishing as an example.

1, 30 mesh metal grinding discs, 30 mesh and 100 mesh resin grinding and polishing concrete floor, so that the concrete floor exposed uniform aggregate;

2. Spray Nalut Hansi lithium-based concrete sealing curing agent;

3,300,500,1000 mesh resin grinding and polishing concrete floor;

4. Spray Nalut Hansi lithium-based concrete sealing curing agent;

5. High polishing machine with diamond animal hair pad polishing concrete floor.

The above is the construction process of polished concrete flooring. For more information, please contact Nalut Technology.

Hello, I'm glad to answer for you.

1. Select a qualified construction team; In order to achieve a satisfactory decorative effect, you should choose to press"Instructions for use of porcelain wall and floor tiles"And GB50209 "Code for Construction and Acceptance of Building Ground Engineering" and JGJ73 "Code for Construction and Acceptance of Building Decoration Engineering" require the construction of a sophisticated construction team, whether the decorative effect of porcelain Xiaozao bricks can achieve the expected ideal goal, the quality of construction is one of the keys. Clause.

2. Check first and then pave: During construction, please pay attention to the color number and actual size of the variety marked on the outer packaging, and the products of the same color number and size should also be used after inspection. When inspecting, you can take a certain number of bricks to try to pave in an open space, stand at a position of about three meters to check the appearance quality of color number, size, flatness, etc., if you are not satisfied (including the paving process found), please suspend the construction and reflect to the company or dealers in time.

Clause. Third, it is necessary to properly leave seams and pave them. In view of the inadvertent early users in the paving of floor tiles, only pay attention to the beauty of the paving and use no seam paving. It turns out:

Due to the great difference in the thermal expansion and contraction coefficient of the base layer, the adhesive layer and the tile itself when paving the floor tiles, under the damage of heat and cold stress in 1 2 years, the paving without leaving joints is easy to cause problems such as tile bulging and fracture. The cost of re-paving after such problems is re-paved is about 4:1.

In order to ensure the long-term interests of users, we sincerely ask the majority of users to leave seams and pave. Clause.

Fourth, while leveling while paving, when paving the ground tiles, it is recommended that the screed area paved with cement mortar should not be too large, so as not to screed cement mortar more than the initial setting time (about 45 minutes), resulting in the brick and the adhesive layer bonding is not compact, resulting in easy hollowing and other quality problems. Clause.

Fifth, the seam is moderate, when the seam is paved, the spacing of the polished bricks is 2mm 5mm, (from the overall paving effect and aesthetics and the actual needs of the seam can be 2mm). In addition, at the edge of stairs, columns, corridors and walls, etc., seams should also be left 1mm 3mm (after the tile paving on the ground or wall, the gap between the tile joints should be cleaned in time, and the caulking work should be carried out at least 24 hours later.) Before caulking, the edge of the tile should be moistened and a special adhesive for the tile should be used, if the grout is used, 1:

1 cement slurry and grout with suitable tools to ensure the depth of penetration. Clause.

6. Avoid hollowing, paving should be carried out after the substrate is solidified, when paving tiles, first the tile and the veneer surface at a certain angle (about 15 degrees), and then gently push the horizontal direction with your hand to make the brick bottom and the veneer balanced, so as to facilitate the discharge of air bubbles; Then tap the brick surface with the handle to make the bottom of the brick fully slurry, so as to avoid hollowing; Then use wood or glue to knock the brick surface to a smooth level, and at the same time, measure it with a level to ensure that the tile is paved horizontally. Clause.

7. Clean up in time, the product should be paved for about 1 hour (depending on the climate and the degree of cement coagulation) to wipe the cement slurry with wood bran or sponge in time to avoid the surface of the dirt for too long and difficult to clean.

Polished concrete floor refers to the concrete sealing curing agent floor, and the benefits of curing the floor are roughly as follows:

a.Hardening and curing.

Treating cement floors with concrete sealant curing agents can significantly improve the mechanical properties of the floor. The ground treated with concrete sealing curing agent can adapt to high-intensity operations, even heavy industry workshops are also competent, up to 7-8 Mohs hardness can not be afraid of most of the impact and rolling, common trailers and forklifts in the plant can not leave the slightest scratch or tire trace on the cured floor, which can effectively solve the ground problems such as cracks and potholes, sand and ash.

b.Sealing impermeability.

Concrete sealing curing agent is not a waterproof material in the strict sense, but it also has a good waterproof, impermeable and moisture-proof ability, and the industry often uses 24h penetration reduction to indicate its waterproof ability, and we can still get a glimpse of its good waterproof ability through relevant data.

The solidified floor with good anti-seepage ability can block most of the foreign substances such as water, acid, alkali, oil, juice, dirt, algae, etc., and is used in large-scale aquaculture industries, such as meat plants, aquaculture farms, etc., which can effectively maintain the cleanliness and hygiene of the site; Coupled with the overall seamless design, daily cleaning will also be more convenient and efficient. Based on this property, concrete sealing and curing agent floors are also commonly used in humid underground parking environments.

c.Decorative beautification effect.

The curing process combined with the upper polishing process can play a role in beautifying the floor, and the cured floor after high mesh polishing can create a marble-like luster.

Concrete sealing and curing agent is suitable for a variety of cement floors, and in practice, many owners use this material to renovate the floor of old factories. One of the typical is terrazzo, emery and other aggregate floor, the use of concrete sealing curing agent to create a high-strength crystal surface layer, but also well retain the texture of the original ground, complementing each other can push the appearance and beauty of the aggregate ground to a higher level.

The concrete sealing curing agent mainly adopts the construction method of immersion grinding. In actual operation, after the ground is leveled and cleaned, the material is evenly sprayed on the ground many times, so that the material can react with the free calcium oxide component in the concrete through effective penetration to form a solid silica sol, and the effect of being as strong as steel and bright as a mirror can be formed after being treated by the floor grinder in the later stage. The specific construction method is detailed in the relevant plan.

Benefits of polished concrete? How to do polished concrete flooring?

Polished concrete floor from 2010 into China, is now developing in the direction of high-end, polished concrete floor to use Nalut Hanjia lithium concrete sealing curing agent and Nalute Hansi lithium concrete sealing curing agent, polished concrete floor using a large grinding machine, with concrete polishing grinding disc grinding, with Nalute armor, Han wire to seal and solidify, seal the concrete surface, so that the concrete floor is beautiful and generous, dustproof and wear-resistant, seepage and stain-resistant. There are many benefits of this kind of polished concrete, here is an example of Nalut polished concrete flooring to describe the benefits of polished concrete flooring as follows:

What are the benefits of Nalut polished concrete flooring?

1. The polished concrete floor can fill the pores of the ground surface, effectively increase the structural density, and greatly enhance the hardness and wear resistance of the concrete ground surface.

2. Polished concrete floor Greatly reduce the cement and lime that are not completely hydrated on the surface of the ground, and the polished concrete floor can completely solve the dust problem of the concrete floor.

3. Polished concrete floor can greatly reduce the path of water flow of the surface structure of the ground, polished concrete floor can effectively prevent the penetration of water and chemicals, and polished concrete floor can improve the ability of concrete floor to resist water and chemical corrosion.

4. Polished concrete floor can make the surface structure of the concrete floor dense, so that the concrete floor is easy to produce higher luster after natural friction or polishing, and looks more bright and beautiful.

As for polished concrete and polished concrete flooring, how to do it? We take the Nalut polished concrete floor as an example to introduce the practice of polishing concrete as follows:

Construction method of concrete sealing curing agent for defending concrete and sealing curing agent for defending silk.

1. Base surface treatment: Appropriate treatment should be carried out according to the specific situation, such as removing curing agents, oil stains, dust, building slurry, wall residues and removing loose materials left on the foundation surface.

2. Grinding with a grinding machine with 30, 100 mesh, 300 mesh resin grinding discs (wet grinding with water). Grind 3-5 times depending on the ground conditions. The ground should be treated as flat and uniform as possible, and the smoother the ground, the more ideal the effect.

3. After the ground is dry, spray the Nalut polycarbon silicon concrete sealing and curing agent on the ground, and push it evenly with dust to ensure that the absorption of the material on the ground is as consistent as possible.

4. After the ground is dry, add water to wet the ground and grind 300, 500 and 1000 mesh grinding discs respectively.

5. Roll the Nalut polycarbon silica concrete sealing curing agent with a roller and roll it on the ground and dry it.

6. Use a high-speed polishing machine with No. 3 animal hair pad to dry and throw the ground. (If there is no high-speed polishing machine, you can use a grinder with 3m black pad dry polishing).

Polished concrete flooring refers to curing floors, and the main construction material of this type of floor is concrete sealing curing agent, so it is also called concrete sealing curing agent floor.

Concrete sealing curing agent is a widely used concrete sealant, hardener and dustproof agent in the construction industry, which is often used in factory workshops, underground garages and other places, and is an important means to create high-strength floors, dust-free floors and impermeable floors. As a practical chemical building material, the concrete sealing curing agent reacts with the cement components in the ground to produce a strong and dense hydrated calcium silicate substance, which then seals the hardened concrete structure and increases the hardness and wear resistance of the concrete. After polishing in the later stage, it can form a strong as steel and bright as a mirror.

The functional characteristics (benefits) of concrete sealing curing agents are as follows:

1. High strength.

Concrete sealing curing agent is obviously different from other floor materials in its mechanical properties, its finished ground is one of the highest hardness specifications of the floor type, with a high level of compressive capacity, weathering resistance, load-bearing capacity, wear resistance, but also has a good anti-depreciation ability, the service life can usually be as long as 20-40 years.

2. Sealed and impermeable.

As a chemical building material, the concrete sealing curing agent will generate a strong and dense silica sol substance in the ground structure after reacting with the cement floor, which not only improves the mechanical properties of the ground, but also achieves the effect of sealing and impermeability, and improves the chemical resistance to most organic acids, alkalis, chemical salts, food, fats, fuels, lubricating oils and similar solvents.

3. Dustproof. Concrete sealing curing agent can seal the ground into a strong and dense whole, with good dustproof ability, which is an effective way to solve the problem of sand and ash on the cement floor. The dustproof grade of concrete sealing curing agent floor is 100,000 grades, and it is often used in the construction of dust-free workshops in electronics, pharmaceutical, food, beverage, cosmetics, machinery, scientific research, medical and other industries.

Fourth, the crystal surface layer is built.

After the concrete sealing curing agent floor is polished and polished with a high mesh number in the later stage, it can create a high-gloss mirror effect. Based on this characteristic, many aggregate floors on the market are gradually phasing out the old waxing process and switching to concrete sealing curing agent for crystal surface layer construction. The use of concrete sealing curing agent to treat the aggregate floor, while creating a high-strength crystal surface layer, also retains the texture of the original ground, and the complementary combination can push the appearance and beauty of the aggregate floor to a higher level.
