Exterior Caulking/Sealants

[conmoto]

This what many are using now, it does not contain silicone:
Geocel 28100V Pro Flex Crystal Clear RV Flexible Sealant - 10 oz. by Geocel
It does come in other colors as well.
I know this was mentioned earlier but I thought I would just do a X2!

I'm new to owning a motorhome so I would like to get recommendations on what caulking to use and what solvents are used to clean the seams and joints before applying the new caulk. Also, are there any tools and techniques used in removing the old caulk?

Thank you for your help.

Hi George & Susan,

I would also recommend using the Geocel ProFlex sealant instead of Silicone sealant. Just as good (if not better) adhesion without the issue of the silicone residue preventing future seals from sticking as well.

Sikkens makes several great products for sealing any issues you might have that are not related to the roof. I also use Proflex and it is also good.

Last year I replaced all the sealant where my fiberglass roof meets the front and rear caps, as well as where the roof wraps around over the side to the wall/roof seams. I used plastic disposable putty knives (Home Depot paint department), small plastic bristle brushes (Home Depot paint department), 3M Adhesive Remover (1 quart can, NAPA), and sometimes a little acetone on an old t-shirt. I worked slow and carefully with excellent results with no damage to the fiberglass roof or gelcoat/painted side seam.

It was recommended by the IRV2/Alpine Owners site that 3M sealants were used with success. I used 3M #5200 Adhesive Sealant with great results. Easy to apply, and then contour with a wet finger. A little fine water mist can help during that process. It can be painted, and I did (the body shop did). Never dries out, and maintains some elasticity.

#5200: Black or white. Fast cure or slower (24 hour)cure. Pretty much permanent.

#4200: Black or white. Fast cure or slower (24 hour) cure. Also great adhesion, but "removable" in the future.

Hope that helps.

Hello Ray,

Thank you for your response. This is the information I was needing. Again this forum comes through with answers and suggestions for new owners of an RV like us.
Thank you again.

I use the EternaBond 4" tape for most applications. To seal the small openings I would recommend the Dicor 502LSW.
