To ensure the flatness of the wall meets the requirements, cushion blocks can be pre-set in the air layer for leveling. Immediately use a ruler and a plumb line for inspection, and adjust any items that do not meet the specifications in a timely manner. The use of adhesives. The bonding strength of fast hardening adhesive to polystyrene board increases rapidly, which can quickly bond the polystyrene board firmly. However, this adhesive has a certain degree of brittleness. During use, if the surface of the polystyrene board undergoes significant deformation or encounters severe vibration or impact, there is a possibility of detachment between the polystyrene board and the wall in some parts. Four fifths of the evenly distributed bonding points should use fast hardening adhesive, and one-fifth of the points should use slow hardening adhesive.

When high-strength road repair materials are applied to road surface repair, a lot of things need to be mixed in order to achieve strength. Although high-strength road repair materials have high strength, they are relatively brittle overall. In this case, it is recommended to add steel fiber high-strength road repair materials during the mixing process, which can produce buffering under huge pressure.  

Secondly, it is necessary to choose high-strength road repair materials that solidify quickly and reach strength within 2 hours, because during road repair, it is necessary to open to traffic in a short period of time.

Then, when selecting steel fibers, it is important to pay attention to the proportion of addition, which depends on different situations, such as high-strength road repair materials and steel

Please refer to the guidance of technical personnel from the grouting material manufacturer for the proportion of fibers.

So, if you are interested in installing granite countertops in your bathroom or kitchen, you can freely mix and match various colored granite tiles. If your bathroom already has a specific color theme, choose complementary colors or another light and shadow effect color based on the wall color and decoration theme color. Assuming a bathroom has pink or walls, charming white windowsills, and light green granite countertops, it would be a multi bathroom. On the other hand, the different light and shadow effects of pink or peach also have amazing effects. If your bathroom is pink or rose colored, try using a dark red granite countertop.

Steel fibers need to be added during the mixing process to ensure even mixing.

Cleaning the road surface:

1. The road surface needs to be cleaned thoroughly and there should be no debris

2. Need to carve out a certain height for grouting

3. Need maintenance, watering and moisturizing the road surface

4. After the road repair, it will be open to traffic in about 2 hours.

In recent years, marble has been widely used in furniture manufacturing. Marble dining tables and TV cabinets are highly favored by consumers due to their crystal clear and moist surface, warm and elegant texture, beautiful patterns and textures, and the advantages of not being afraid of dirt or scalding. But currently, the market is flooded with a large number of low-quality or even counterfeit marble furniture. These so-called marble furniture not only do not have the advantages of high-quality marble furniture, but also contain a large amount of radioactive elements, which pose many health hazards to consumers. The identification of the authenticity of marble furniture sold in the market can be divided into natural marble and artificial marble, and natural marble can be divided into high-quality marble and low-quality marble. When choosing marble furniture, the first thing to understand is the differences between them.

Granite is not easily weathered or deteriorated, and its appearance color can be maintained for more than a hundred years, so it is mostly used for exterior wall decoration. Due to its strong corrosion resistance to air, higher hardness and wear resistance than marble, it is an ideal natural stone for architectural decoration in terms of durability that other stones such as marble and terrazzo cannot match. Compared with marble, granite has less variation in color and pattern, but has more flexible changes in texture, while appearing more solemn and classical in overall feeling. The material of high-quality stone should be uniform and complete, avoiding problems such as dark cracks, black scars, and color differences. Pay attention to the composition of the stone and avoid containing harmful substances such as excessive iron, iron oxide, carbonaceous matter, and clay; Pay attention to the radiation level of the stone; Pay attention to whether the stone contains mineral components with high thermal expansion coefficient, thermal conductivity, and electrical conductivity to avoid the dangers of cracks, thermal conductivity, and electrical conductivity.
