1. Seal the gap with silicone adhesive.
Silicone adhesive is a commonly used filling material for edge seam of floor drain. Before sealing the gap of the floor drain, it is necessary to ensure that there is no dust and debris around the floor drain. Then, the silicone adhesive is extruded to a fixed length, and evenly spread on the gap of the floor drain with a seal *. Silicone glue needs to be dried for a period of time until it is completely dry.
2. Seal the gap with cement.
If the floor drain has a large gap, it can be sealed with cement. Before sealing the edge joint of the floor drain with cement, measure the gap size with the floor drain size first. Then mix the cement and spread it evenly on the gap. After the cement is dried, smooth its surface with sandpaper or other tools.
3. Fill the gap with expanded rubber sheet.
Expandable rubber sheet is a kind of high-performance sealing material, which can be used to fill the edge joints of floor drains. It has the characteristics of high temperature resistance, aging resistance, water resistance and moisture resistance. Cut the expanded rubber sheet into appropriate size and embed it in the gap of the floor drain to make it flush with the surface of the floor drain. Gaps in the expanded rubber sheet need to be pasted evenly, and its compactness should be checked.
Replace floor drain
If the edge seam of the floor drain is damaged too badly or cannot be repaired, it needs to be replaced. Before replacing the floor drain, you must turn off the water source and check the floor drain model. Buy the corresponding floor drain according to its model, and check whether its sealing and installation position are correct before installation.
The above are several methods to deal with the edge seam of floor drain. Which method to choose depends on several factors, such as the gap size and the material of the floor drain. Before choosing any method, carefully understand the quality and applicability of materials to ensure reliable and effective repair.
