Can the floor leather still be laid on top if it's damaged

After the floor leather is damaged, new floor leather can usually be directly laid on top, but it is necessary to ensure that the original ground is flat and not severely damaged. If the original ground has curled edges, bulges, or mold problems, it needs to be repaired before laying. When there is slight wear or scratches on the surface of the flooring leather, it can be directly covered with new flooring leather. The thickness of the new material should be sufficient to cover the original defects. Before laying, the old floor should be thoroughly cleaned to remove dust and oil stains. The use of self-adhesive floor leather can simplify the construction process, but it should be noted that the joints need to be reinforced with special glue. If choosing lock on floor leather, it is necessary to check whether the hardness of the old floor meets the load-bearing requirements. When there are large areas of cracking or loose base layers on the original ground, direct laying may cause rapid deformation of the new flooring. Loose old materials need to be removed, and depressions should be filled with cement mortar. After complete drying, they should be polished flat. Moisture proof film should be laid first in damp environments to prevent water vapor from corroding the new floor leather adhesive layer. For underfloor heating rooms, high-temperature resistant specialized floor leather should be selected to prevent joint cracking caused by thermal expansion and contraction. Before laying, it is recommended to test the moisture content of the ground. If it exceeds the standard value, moisture-proof treatment should be carried out. Avoid scratching the surface with sharp objects during daily use and regularly maintain it with neutral cleaning agents. If there are serious structural problems with the old floor, it is recommended to completely demolish it and redo the base treatment to ensure the service life of the new floor leather. Choose products that meet environmental standards and maintain ventilation after construction to reduce formaldehyde emissions.
