Excuse me, is granite fine chisel surface and litchi surface the same concept?

Granite fine-grained surface is burnt surface, which is formed after baking with fire, that is, drawing porcelain, while fine-grained surface is chiseled out, such as litchi surface chiseled out by litchi hammer. The processing technology of the two surfaces is different.

Granite has compact structure, high compressive strength, low water absorption, high surface hardness, good chemical stability and durability, but poor fire resistance. Granite is fine-grained, medium-grained, coarse-grained, or punctate, with uniform and fine particles, small voids (porosity is generally 0.3% ~ 0.7%), low water absorption (water absorption is generally 0. 15% ~ 0.46%) and good frost resistance.

Precautions:

1. During construction, the scaffold should be about 30cm away from the wall. If the distance is too close, there may be marks on the spraying part between the upper and lower scaffolding, which will affect the decorative effect.

2. Unspray parts and objects shall be separated by baffles or paper.

3. The temperature should be higher than 40℃ during construction, and it is not suitable for construction when the wind force is greater than 4. Rain and snow weather should be avoided within 24 hours after the main coating is sprayed.

4, after the completion of the main coating construction, tools should be washed with water immediately.

5, in the process of construction, to ensure the long-term stability of spray gun pressure and air compressor.
