Should a suspect leak be identified for a Trailcore Body, the following points need to be inspected and verified for leakage:

• Body Roof seals x 4, Extrusion Welds, Rivets 

• Front wall Rivets & Air Vent

• Handle corners/welds are in place

• Rear-door seal is secure and intact 

Inspecting Roof Seals

Check all sealed roof joins for pin holes, cracking or joint separation 

Remove or reseal as needed 

Inspecting Roof Welds

Check roof extrusion welds for any cracks, pin holes or ingress points

Apply sealant as needed 

Example of aged seal showing hairline cracking - remove and reseal

If a small section of the seal is damaged, mask around just the damaged section and apply black sealer to the damaged area.

(Standard spec used by Utemaster is black Sabre Bond SMP60B)

Leave the seal for 24 hours to fully dry before water testing.

Note: Water can travel along the join before emerging at a different location.

Remove any roof-mounted accessories, such as a cantilever rack or roof platform.

Remove the existing sealant from the roof join. Use a craft knife if required and clean away any remaining sealant

Apply masking tape along both sides of the roof join, leaving a 10 mm gap between the tape.

Apply a continuous bead of sealant along the groove.

Using a rubber or plastic applicator, press the sealant firmly into the groove to ensure full coverage.

Remove the masking tape by pulling it away from the sealed join while the sealant is still wet.

Inspect joins for any pin holes or bubbles.

Allow the sealant to cure for 4 hours before performing a water test.

Once the repair has passed the water test, reinstall the roof-mounted accessories.

It is recommended to leave the seal to dry for 12 - 24 hours before re-installing roof accessories to prevent these from damaging the seal.
