Before the floor is laid, the cement floor needs to go through a series of treatments to ensure the flatness, firmness and durability of the floor. This article will introduce in detail the aspects of cleaning, repair, moisture protection and coating treatment.
1. Clean the cement floor.
Before laying the floor, the cement floor needs to be carefully cleaned first. Remove dust, oil, debris, etc. from the ground, which can be cleaned with a broom and vacuum cleaner. For stubborn stains, scrubbing can be done with detergent and brushes. While making sure the floor is clean, check it for obvious cracks or loose areas.
2. Repair the cement floor.
1.Filling cracks and potholes: For cracks and potholes in concrete floors, cement mortar can be used to repair them. Once the mortar is evenly mixed, fill the cracks and potholes with a spatula or spatula, then scrape the surface with a scraper and make sure that the patched area is level with the surrounding ground.
2.Trimming the ground height difference: If there is a height difference in the cement floor, self-leveling cement can be used for trimming. Pour the self-leveling cement evenly on the ground, use gravity to automatically distribute it evenly, and level it slightly. Take care to allow an appropriate curing time according to the product instructions.
3. Moisture-proof treatment.
If the concrete floor is in a humid environment, it needs to be treated with moisture to avoid moisture problems on the floor in the future.
1.Check the moisture level of the floor: Use a hygrometer or a simple humidity test method to check whether the moisture content of the floor meets the requirements of the floor installation. Ground humidity of less than 3% is usually required.
2.Protective layer treatment: If the ground humidity is high, you can apply a layer of waterproof paint or moisture-proof paint on the cement floor to effectively isolate the moisture between the ground and the floor.
Fourth, coating treatment.
1.Primer treatment: Before laying the floor, the primer can be used for the base treatment to increase the adhesion between the ground and the floor and avoid loosening or cracking of the floor. Choose the right primer and coating, depending on the condition of the ground and the desired effect.
2.Varnishing: If you want a brighter look on the concrete floor, you can do it. After cleaning and repairing, choose a suitable floor polish and apply it evenly to the floor with a brush, roller or spray.
Summary: The treatment of the cement floor before laying the floor is crucial, not only to improve the installation quality and service life of the floor, but also to increase the aesthetics and comfort of the floor. Cleaning, repairing, moisture protection and coating ensure that the floor is flat, firm and durable. Before laying the floor, it is important to carry out a careful treatment to obtain the desired pavement effect.
