Removing old caulk after softening it

[Brownleaf]

I am planning on using goo-gone caulk remover to soften old caulk. Anyone have any feedback on that choice and removing old caulk? Thanks Doug

Yes, there is often a fine line between a useful tool working very well & that same tool doing damage. A pressure washer is another such tool.

Some guys get a little rowdy after you say "caulk" too many times.

Because removing this caulk on the side has proved to be so messy and inexact- peeling bad into the good causing more problems, for the rest of the side issues I am just going to spot add.With what I am doing right now, I am creating more probems than existed before. The already existing caulk is very tough-thats good, I leave it as is, because the cracks or pin size holes are so small that just adding should do the job. Doug

This is another 'no easy way' job.

I replaced a TV antenna a few years ago. It was a combo OTA/Satellite dish thing that was factory installed. Never did get a receiver for it & the omni directional OTA antenna was all but useless.

I have removed silicone & polyurethane on boats before so the same method was used on the antenna base. Very very carefully use a heat gun to soften the material & scrape it up as you go.

It takes some fudging around to get the heat/scrape method down but goes steadily once figured out.

Goo-gone sray gel is to liquidy, you have to wipe constantly to keep it from draining lower than the area you are softening. Next time I will use the DAP caulk remover assuming it is a real gel. Doug

HMMMM, are you stating your question is about the sides of the RV and NOT the roof???

OH really?????? Maybe if people would actually post what they are asking so people don't have to guess may help.

PLENTY of people want to know how to remove caulking in other places other than the roof.

Mineral spirits won't eat into the finish of gel-coat, most all fully cured paints or powder coats.
Not is you use it for cleanup, you'll still need to use a different solvent or wash with soap to clean the surface prior to re-caulking. Mineral spirits/turpentine/paint thinner does leave an oily residue.

plastic razor blades and/or plastic putty knife works for me after softening with DAP caulk remover on fiberglass.

I do have to try plastic razor blades one of these days. I'm pretty used to using a metal blade, but still have to be careful and the occasional nick or gouge is bound to happen.
The plastic ones seem to have their place with more delicate tasks.

There are lots of good "handles" if you use a razor blade.

The roof curves down over the edge to the little gutters-that should call for reg caulk not self leveling right? Doug
