Self-leveling construction need to pay attention to what points

Self-leveling process
Check the ground condition:
1 cement mortar surface can not have sand, mortar surface to keep clean. If the ground from the sand, shall not use self leveling.
2 knock on the original cement floor, cement mortar and the ground can not be empty shell
3 The ground must be dry, and the moisture content shall not exceed 16-20 degrees measured with a special test instrument. If it is not dry, it needs to be dried before self-leveling.
4 Base cement strength shall not be less than 10Mpa
Base surface cleaning cleaning:
1 clear the site, do not place anything on the ground.
2 with the surface shovel will be obvious residual paint and other ground construction residue removal. Grind the obvious boss ground with a grinder to minimize the rise and fall of the ground.
3 Clean up the residual engineering ash at the corners and corners
4 Remove impurities, floating dust and sand particles as a whole.
Upper interface agent:
According to the interface agent instruction manual, interface treatment on the ground. It is recommended to brush the interface agent twice. Interface agent can increase the bonding force of self-leveling cement and the ground, and prevent the shelling and cracking of self-leveling cement. It is recommended that the ground treatment agent be applied twice.
Self-flowing cement:
1 Find a suitable barrel and mix self-leveling cement according to the material-water ratio of self-leveling cement manufacturers. When the self-leveling cement is placed in the water, the self-leveling cement is poured while using an electric mixer. Stir slightly longer to allow the reaction to occur. After stirring, it shall be fluid and there shall be no powder or lump. Use within half an hour after stirring.
2 pour the artesian cement on the ground. Use a self-leveling rake with teeth to rake the area as required.
3 After self-leveling and self-leveling, roll with a toothed roller to release the gas to prevent foaming. Special attention should be paid to the leveling of the self-leveling lap joint.
Fine grinding treatment
After the self-leveling is dry, the plane will have small holes, particles and floating dust, and the doorway corridor may have a height difference. Therefore, after self leveling and drying, fine grinding can be carried out. Fine grinding treatment can be carried out when the self-leveling cement is not dry, but the self-leveling must have a certain hardness. After sanding, vacuum the static dust.
