Did you do the full length or multiple corners before you smoothed it out? It probably started to set up before you smoothed it out. I usually do a couple feet at a time. I also dip my finger (wearing latex gloves) in soapy water before I smooth it out.
That’s how my wife describes me. Chunky and rough.
Is this something we all should be doing or was yours leaking?
I had a dealer tell me he didn’t care if it looked like a 3 year old caulked it as long as it was water tight.
What the above commenter said.
Depending on the days weather and if you are in the sun. Caulking can skin over very quickly. On warm days I can only do 12”-24” at a time. Keeping a wet sponge on hand is helpful. I also spray with soapy water if needed. That keeps it went until smoothed nicely.
You probably have to pull it out. If you really want a nice caulk job you should remove the old caulk, clean the area (denatured alcohol) and personally I would tape the edges and then spread the caulk out. The tape should give you a perfect edge. This process will only add an extra 10-20 hours on caulking an entire camper 🙂
This was a job for silicone. I think the no-sag is for roofs with rubber membrane.
