Decoration technology sharing: construction technology and matters needing attention of epoxy colored sand floor

At present, there are more and more choices of floor decoration materials. In addition to the familiar tiles and wooden floors, there are many other new materials, among which epoxy colored sand floors are one. What is epoxy colored sand floor? What are the construction techniques and precautions of epoxy colored sand floor? Let us understand:

What is epoxy colored sand floor?

Epoxy colored sand decorative floor is a new type of composite decorative floor which is seamlessly integrated by colored quartz sand. By freely matching one or more kinds of colored quartz sand, colorful decorative colors and patterns are formed, which has the advantages of elegant decorative texture, wear resistance, compression resistance, chemical corrosion resistance, non-slip, fire prevention and waterproof. Colored sand epoxy resin decorative floor has stable and reliable performance, more beautiful decorative effect and wider application range, and can be applied to industrial floors, commercial and civil building floors. In recent years, it is very popular in developed countries such as Europe and America, and is known as "colored sand seamless hard carpet".

Construction technology of epoxy colored sand floor;

First, the epoxy colored sand floor base treatment

1. Basic requirements

(1) The base must be a reinforced concrete structure. The strength grade shall not be lower than C25.

(2) The base course should be leveled with protoplasm and polished by machine to achieve leveling.

(3) It takes at least 28 days to maintain the concrete ground base in summer, and the maintenance time in winter is appropriately extended.

(4) A moistureproof layer must be set under the base, and the moisture content of the base must be lower than 8%.

(5) During the construction period, the surface of the base should be kept clean and free of pollutants. All pollutants, such as fat, grease, paint residue, chemicals and laitance, must be removed.

(6) The construction temperature of epoxy colored sand floor should be controlled above 5℃, and the relative humidity should be controlled below 60%.

2. Construction method of epoxy colored sand floor

(1) technicians must use a moisture content tester to measure the moisture content of the ground before entering the site, and the next working procedure can be carried out only after reaching the construction standard below 8%.

(2) Construction personnel use cleaning tools to remove the original laitance and sand.

(3) Determine the place with large local drop, and polish the raised part with an angle grinder.

(4) Use a dust-free grinder to polish all the ground, remove the loose layer, cement stains, lime film and other foreign bodies on the original ground, use an angle grinder to polish the parts with large local drop, and use a vacuum cleaner to suck the ground and corners clean.

(5) Repair the ground pit and cut the ground joint with the base repairing material.

3. Matters needing attention for epoxy colored sand floor:

The moisture content of concrete is required to be less than 8% to ensure the bond strength between epoxy resin floor and concrete.

Second, the epoxy colored sand floor primer construction

1. material

Use epoxy high permeability primer.

2. Epoxy colored sand floor construction method:

The materials are fully stirred according to the proportion, and the materials are repeatedly scraped by the scraping process. Make the epoxy high-permeability primer seal and penetrate into the concrete base, ensure the combination of epoxy colored sand floor and concrete, and improve the durability of bonding.

3. Matters needing attention for epoxy colored sand floor:

(1) According to the compactness and oil absorption of the substrate, it should be coated to saturation.

(2) the primer should be uniform, and individual white places should be repainted.

(3) There must be enough permeability to ensure that the primer can penetrate into the concrete surface.

Third, make a colored sand (or three inches of sand) effect layer.

1. material

Color sand (three-inch sand) and transparent epoxy resin are mixed and stirred.

2. Construction method:

Pave the pavement with a thickness of about 5.5 mm with a paver, compact and level it with artificial nail shoes, and compact and level it with a trowel in a large area to make the surface smooth, thus forming a seamless epoxy colored sand layer.

3. Preventive measures

When paving, the surface of epoxy colored sand layer must be flat as a whole.

Fourthly, a transparent high-strength wear-resistant topcoat layer.

1. material

Transparent high-strength polyurethane glossy or matte wear-resistant topcoat.

2. Construction method

(1) Fine polish the colored sand layer with a grinder.

(2) Cleaning and dust removal to obtain a good and delicate appearance effect of colored sand.

(3) Roll coating transparent high-strength polyurethane matte wear-resistant finish.

3. Preventive measures

(1) must be free of knife marks and finely ground and polished.

(2) Must be clean and dust-free.

(3) roller coating must be without leakage.
