How can the renovation of the old terrazzo floor be effective?

Terrazzo floor renovation method.

1. The preliminary preparation work is mainly to prepare construction materials and clarify the operating conditions.

Second, clear process flow:

Treatment and wetting of the base layer

Plastering cakes, making punching bars, wiping the leveling layer, curing, inlay and sub-lattice strips, laying cement and stone slurry, curing and trying, grinding the first time and replenishing the slurry, grinding the second time and replenishing the slurry, grinding the third time and curing, waxing and polishing with oxalic acid.

3. Carry out the operation.

1. Make a screed.

The leveling layer needs to use a 1:3 ratio of dry hard cement mortar, first flatten the mortar, and then use a pressure ruler to press the bar to complete the scraping, and then use a wooden trowel to grind and compact again.

2. Grid strip inlay.

Use pure cement slurry to wipe the lower part of the lattice strip into a figure-eight angle through the long seat embedded firmly, and remember to bury the iron wire worn by the copper strip. The coating height of pure cement slurry is 3 5mm lower than the lattice strip, and the lattice strip should be firmly inlaid, the joint should be tight, the top surface should be on the same plane, and the line should be checked for its flatness and straightness.

3. Wipe the surface layer of stone slurry.

The mud and stone slurry must be measured in strict accordance with the mix ratio, and the stone slurry surface should be swept at least twice with the hair to open the slurry, check the uniformity of the stone particles, and then smooth and compact with an iron trowel until the slurry is spread. It is required that the corrugations be flattened, and the stones on the top surface of the lattice strip should be removed.

4. Polishing. Large-area construction should be ground with a mechanical stone grinder, small areas and corners can be ground with a small portable grinder, and manual grinding can be used when mechanical grinding cannot be used locally.

1. Concrete sealing curing agent is a hardened material that reacts with minerals in concrete to increase the strength and density of concrete. It is mainly used for concrete, emery floor, terrazzo ground reinforcement, hardening, dustproof, wear-resistant, anti-fouling, anti-seepage treatment, ground renovation construction treatment agent supplemented by related mechanical grinding, can make the ground become marble-like gloss, the service life is more than 25 years.

2. Description of the old terrazzo floor renovation product:

1. High permeability, powder environmental protection, colorless, tasteless, non-toxic, non-flammable, transparent liquid products;

2. A new generation of high-permeability process replaces the traditional surface coating process, and there is no falling off phenomenon at all;

3. It can effectively improve the hardness, strength, density, compressive strength, wear resistance, non-whitening, and more durable on the surface of terrazzo;

4. Tightening the capillaries, which can effectively inhibit external pollutants from entering the concrete, and improve the ability of the concrete floor to resist water and chemical corrosion;

5. Completely solve the problem of sand and dust prevention on terrazzo floor, and directly reduce the labor cost of cleaning;

6. After long-term use and correct cleaning and maintenance, the ground after grinding will show a charming luster like marble, which is more glossy and beautiful. And it has a charming luster like marble, which looks even brighter.

Terrazzo is something that few people have heard of! In fact, terrazzo is made by mixing some fragments of glass and quartz stone into cement sticky, and then grinding and polishing them with some processes. So, how to renovate terrazzo floors?

Next, let's find out with me!

First of all, the old terrazzo should be coarsely grinded, and then the terrazzo layer should be polished off to expose the new surface, and then the ground should be solidified, and then the terrazzo should be renovated.

Where is terrazzo generally used.

1. Terrazzo is made of stone chips, cement and other raw materials, and then added an appropriate amount of water to stir, and to stir evenly, and then smeared on the surface of the building, used in the decoration of the building. After a short period of solidification, it is then splashed with a little water and smoothed with grinding equipment or diamond. Terrazzo can be designed into different finished products according to the needs of the designer, so that the decoration of different patterns and patterns can be achieved as the designer wants.

2. The ground characteristics of terrazzo are solid and durable, beautiful and generous, easy to clean, good integrity, smooth and smooth. However, the disadvantage is that the construction process is more complicated, and the noise of the construction is large, the period is long, and the construction site is relatively easy to produce pollution. It is generally used in the partition of the bathroom and the window sill, if it is a public place, it is mostly used in hospitals, corridors or toilet floors, etc., but it will be more suitable for wet places.
