What kind of adhesive should be used to fix water leakage in a truck cargo compartment?
2 Answers
Truck cargo compartment water leakage can be treated with silicone sealant. Below are several methods to address water leakage in vehicle compartments: 1. Severe leakage: If the roof of the box truck has serious water leakage, argon arc welding should be used for sealing. Never use electric welding, as the roof of a box truck is relatively thin, and electric welding could easily cause more extensive damage. 2. Minor leakage: If the leakage is not severe, automotive putty or silicone sealant can be used to seal the gaps. However, the only drawback is poor durability, as leakage may recur after some time.
When dealing with water leaks in truck compartments, I most commonly use silicone sealant because it has excellent waterproofing effects, can withstand high and low temperatures, and is not prone to aging. Last time, my truck's roof gap was leaking, and I applied it. After letting it dry overnight, the leak stopped. The key is to identify where the leak is coming from, such as the edges of the doors or the seams on the roof, then thoroughly clean the area, removing any rust or dirt, before applying the sealant tightly. It's best to buy automotive-specific adhesives, like those from 3M or Loctite, as they are more reliable. If the leak is severe, don't rely solely on sealant—you may need to check if the sealing strips are aging or if there's rust on the undercarriage that requires welding repairs. Once this is done, the truck can be used with confidence, and you won't have to worry about cargo getting wet on rainy days. I recommend regular maintenance of the compartment and frequent leak inspections to prevent issues—it saves both money and hassle.
