If (like me) you are the type of person who applies caulk with the objective of getting professional-looking, smooth joints, then the application and look of lap sealant on a camper roofing will toss you for a loop. Lap sealant looks more like somebody was trying to put icing on a cupcake.

And if someone has recaulked a location, there are even more blobs on top of the older blobs. It appears counter-intuitive to the objective of avoiding water invasion because the application does not always motivate water to drain pipes away. Even an expertly applied application of lap sealant around an air vent looks more like a tiny retention pond after a rain.

To prevent tearing a rubber roof membrane or scratching an aluminum roof, vibrate the tool around the edge of the caulk up until it starts to lift. It's simplest to do this when outdoor temperature levels are above 80 degrees, otherwise you could utilize a hot air gun or blow clothes dryer to thoroughly heat the caulk.

The is to get the old caulk as flush to the rubber surface as possible. Have a small tub, denatured alcohol, and rags nearby to clean up as you go. Store the can and rags in the little tub. Prevent letting the denatured alcohol make contact with the rubber roofing for too long.

Keep the sealant beads approximately 1/2 inch far from the painter's tape (or whatever distance your tube test spread showed).
