Steps to Follow to Seal a Tonneau Cover
Applying seal tape on a truck bed cover is a simple process that can help to keep water from entering the truck bed. Here are the steps you can follow to apply seal tape to your truck bed cover:
- Clean the surface of the truck bed where the seal will be applied. Use alcohol pads or soapy water to remove any dirt or debris.
- Measure the length of the truck bed where the cover will be applied. Cut a piece of seal tape to the appropriate length, ensuring it will be wide enough to cover the entire area where the cover meets the truck bed.
- Peel the backing off of the seal tape, exposing the adhesive side. Be careful not to touch the adhesive with your fingers, which can make it less effective.
- Carefully align the seal tape along the edge of the truck bed where it meets the truck bed. Press the tape firmly against the surface to ensure that it adheres properly.
- Repeat the process for the other side of the truck bed cover and where the cover meets the tailgate.
- Check that the seal tape properly adheres and that there are no air bubbles or wrinkles.
Tip: It’s recommended to do this in warm weather or use a hair dryer to slightly warm up the tape to make the adhesive easier to apply. Also, press the tape firmly to avoid any movements and wrinkles.
Note: You can also place the weather strip where the truck bed interferes with the tailgate at the base and up both sides.

Different ways to Seal a Truck bed cover – Truck bed seam sealer

This is a popular method for sealing truck bed covers. You can apply a bead of silicone sealant along the edges of the cover where it meets the truck bed. This will create a water-tight seal and prevent water from entering the truck bed.
Another option is to use weather stripping. This is a flexible strip of rubber or plastic that can be applied to the edges of the truck bed cover. This creates a tight seal and helps to keep water out of the truck bed.
There are also truck bed covers that have a magnetic sealing system. This creates a tight seal by using magnets that securely hold the cover against the truck bed.
It’s important to note that these methods may need regular maintenance and check to ensure they seal correctly and don’t wear out, especially the first two methods. Moreover, ensure the cover is appropriately aligned and fastened to the truck bed before you seal it.
