Removing old sealant

[DReisinger]

I am replacing the ceiling vent in the fiver with a Maxxair Fan, the instructions say remove ALL old sealant from flange. Is there any thing that will make this go a little easier?

If you have an oscillating multi tool they make special blades for cutting through caulk - I have used on RV and home and find them very useful.

A plastic putty knife and heat gun will do the job. Just be careful with the heat gun, you don't want it too hot.

If you have a larger area, consider a Fein Multi-tool or the Harbor Freight knockoff.

Plastic putty knife and a heat gun or old blow dryer. Dont worry about getting it all off.

Not an easy job, but try using a plastic putty knife. I found that working from the inside edge towards the roof was a bit easier as you could find an edge easier. Take your time and it will turn our great. I did the same project last year.
