Too much caulk

The PO went way overboard caulking this vent. Any suggestions on how to remove this caulk mountain?

I have a couple of those courtesy of POs. I hope I never have to remove them.

As you can see in the picture I have the plastic scraper and some caulk solvent. Underneath the paper towel was a spot that I was soaking in remover. If I extrapolate how long it took to soften and remove this one spot with the above method I would be at this for two to three weeks straight without taking time to go to work...

Give a call to a good AS dealer, Out-of-Doors Mart in NC or Colonial AS in NJ. Anything harder than plastic will scrape the shell. A solvent will disolve the frame of the vent (if plastic).

Get the sealer loosen up at a corner(you made a putty knife with the end sharpened) to get the sealer loosened enough to crasp and pull.Once you get it started you should be able to pull (apply tension)and use sharp edge of PK to cut while pulling.You do not want to scrap the aluminum .It all depends on the type of caulking that was used.

Depending on the type of sealant, applying some heat with a heat gun might speed things up a bit.

The gel Kleen Cutter paint remover works pretty well.

I would use a paint eater wheel on a drill. Carefully take off the bulk. Then proceed as mentioned above once you get close to the shell. It's my opinion based on my own experience, do as you please.

Had the same problem. I used a heat gun and a dull putty knife to remove the bulk of it. Then sprayed it with "Contractor's Solvent", available @ Ace and various hardware stores. Used a 3M pad to remove the residual as I wasn't concerned about marring the finish up there and finished it up with rubbing alcohol to prepare the surface for new caulk.

Alden,
Count Your Blessings, The PO of our 31ft decided the best material to seal the entire roof was with BLACK TAR, APPROX. 5 GALLONS OF BLACK TAR.
It did take 3 weeks to remove all the tar, so I know you can remove that sealant quicker.
Of course you can look at it from a different prospective I did not have any water leaks from above.
Good Luck,
Jack

Alden,

The caulk your trying to remove may not be silicone based.

This,(West Marine), worked pretty well on our black tank vent.
Soak well, let sit, scrape with plastic putty knife. Final wipe-down with mineral spirits.

If your really careful and mask the plastic, 3M brake clean also works very well and is a lot cheaper.

Bob

Braided wire wheel on an angle grinder will eat through it very very fast. You may scrape the aluminum, but no one will ever see it up there... Wear eye protection and gloves, because it will liquify it and splatter and that wheel will fire off metal spears. Once you get the bulk off you can move to a finer wire wheel on a drill to get the last bits right on the surface.
A paint removing disk will work too, but may get clogged.
Heat and a scraper will work, but there are most likely wires that run in the ceiling right near where you're working.

Wow, lots of good ideas! Thanks!

I had been thinking of a heat gun and paint stripper. I need to do something (like suggested) to remove the bulk of this before trying to get it really clean.

West Marine is right down the street from work so I might try some of their solvent too.

If I give up and attack it mechanically I have a Fein Multimaster with scraper blade that will get right under it and remove it but it will scrape the aluminum up so I was going to hold off on that until I try other methods.

Jack, thanks for making me feel better about this!
