Plain treatment: before construction, clean and clear the debris and oil on the concrete floor. Cement based polymer caulking agent is used to repair the large cracks in the ground to reduce the loss of raw materials.

Grind the ground: grind the ground twice with 50 mesh pieces, and then grind the ground twice with 100, 150 and 300 mesh pieces in the same process, until the ground is smooth.

Construction of concrete sealing agent sealing layer: after the construction of hardening layer for 10 hours, the construction of sealing agent shall be carried out. After cleaning the dust on the ground, spray the hardener on the ground evenly with a sprayer. At the same time, use the 100% polyester mop to drag the surface hardener evenly into the concrete.

After the protectant construction, there shall be no fresh water within 3 days. Operation can be started 24 hours after construction, and solid surface can be formed within 10 days during the crystallization period.

Construction of hardening layer of concrete sealing agent: after the ground is cleaned, let the surface of the ground dry for more than 120 minutes, and then carry out the construction of concrete curing agent without surface water. The concrete curing agent is sprayed on the ground evenly with a watering can, and the dust is pushed closely and evenly at the same time.

Spray hardener on dry surfaces and keep them moist for 30 minutes without water. 10 hours after the construction can be manned operation, but the ground can not have water, water phenomenon.

After the construction of hardening layer of concrete curing agent is completed within 24 hours, it can be decided whether to polish the floor or not according to the needs of the floor.
