One、If the floor tiles are damaged, what should be used for repair?
1、The damage is minor.
(1) The old, damaged tiles are still intact, but the joints with other finishes have detached. When repairing, remove all loose mortar from the joints and apply epoxy resin adhesive. Allow it to dry, then fill the joints with a waterproof, flexible jointing material (such as silicone sealant).
(2) When the area of damaged tiles is small, use cloud stone glue with hardening agent, and mix with color powder to match the color of the tiles. Apply the mixture to the gaps in the tiles, and after it has hardened, you can then grind and polish it.
2、The damage is severe.
When the tile damage is severe, it is recommended to remove the damaged tiles, clean the substrate, and then re-lay the tiles. The joints between the newly laid tiles should be filled with white cement mortar, and any excess mortar on the tile surface should be removed.
Two. How to repair damaged floor tiles.
Method 1: Divide the damaged tiles into sections of varying sizes. Use a relatively hard scraper to carefully remove each section of the tile. Then, use a tile cutter to clean the edges of the tiles, carefully shaping them. During the process, pay close attention and be careful not to damage other tiles. once the tiles are cleaned to a sufficient extent, apply cement mortar. Choose a tile of the same color and place it on the floor. Gently tap the tile with a hammer to ensure it is level with the existing floor.
Method 2: If the damaged area of the tiles is located in the interior space, it is best to re-lay the tiles to maintain aesthetic appearance in the future. For areas where furniture is placed or interior corners, ceramic adhesive can be used to fill and smooth the gaps.
Method 3: If the damaged area of the tiles is small, use grout to repair and smooth the damaged area. If you are concerned about aesthetics, you can use decorative items to cover the damaged area.
Method 4: For damaged tiles, thoroughly clean the edges of the tiles first, then embed them with white cement. Gently knock out the damaged tiles using a small hammer. If the tiles are tightly adhered to the substrate, use a knife to demarcate the areas and begin working from the center outwards, gradually removing the damaged tiles.
