Instructions
With the pop up canvas fully open and supported, start on either the roadside or curbside of the camper.
Waterproof the pop up canvas latch assemblies as follows:
1. Remove the latch assembly (Fig. 2). Discard bolts and washers. Do NOT reuse.
2. Clean the pop up's mating surface with lint-free wipes. Make sure no dirt or debris is present before
applying the foam tape.
AWARNING
Keep sealant away from heat and flame.
Sealant may be harmful or fatal if swallowed. May cause lung damage, respiratory tract, skin and
eye irritation. Always use in well ventilated areas. Wear appropriate personal protective equipment.
Inject Geocel® 2300® Vehicle Body Sealant silicone caulk into each of the pop up base's mounting holes
for the latch assembly.
Cut three strips of foam seal tape (Fig. 3); one strip long enough (approximately six inches) to match
the length of the bottom of the latch assembly, and two strips each long enough (approximately two
inches each) to cover the vertical side of latch assembly mounting holes.
Apply the strips of foam seal tape to the canvas pop up latch assembly mating surfaces. Make sure
the bottom and side mounting holes—filled with silicone caulking—are completely covered by the
foam seal tape.
Install the latch assembly in-place over the foam seal tape.
Insert a pointed tool into the latch assembly's mounting holes and puncture through the installed
foam seal tape until contact is made with the pop up's base mounting holes.
Leverage the pointed tool within the mounting holes to properly align the latch assembly with
the base.
