Sikaflex 221 gray or aluminum gray?

Hi silver twinkee (with good stuff inside) comrades
It seems there are gray color choices, and because I want to start out this process on the right foot...
Should I purchase Sikaflex 221 gray? or aluminum gray?
Thanks

What a geat thread on sealants

Kudos to TinTin for envisioning this thread and for the significant contributions from "lewster," for sharing his significant experience.

My 78 Sovereign has many leak issues I working through, but my question relates to the proper way to install and apply sealant to an aluminum patch. I have two patches to install, one on the roof to cover the hole left from on old corroded TV antenna, and I want to eliminate the internal battery compartment and replace the old door with a patch.

One application is on the roof. One application is on the front (side). How should the sealants be applied (probably will use Sika products) both on the inside and the outside of the patch?

What would be most helpful to me is understanding the process once the patch is made and ready to install? For example, do you put sealant between the patch and the skin? In the case of the roof, so you use a self leveling caulk on all the rivets and around the edges of the patch? How do you seal up the interior side of the patch, or is that necessary?

Would really appreciate your input.

Recent observations using Trempro 635 and Parbond. The Trempro shrinks and cracks over time and it tends to have poor adhesive strength and not great tensile strength. It does ok where you have a really thick fillet joint 1/4" or bigger or a flange where it is applied between the two flanges. It does not like movement like on an awning bracket and it does not do well with narrow cracks. The Parbond seems to have better properties and it is a much stronger adhesive. It gets a crust on it eventually and falls apart but up to that point it performs well. The Parbond has better elongation so it does not crack as bad in shifting areas. Probably best to use several layers of this stuff since the top layer can get crusty after several years. These are observations in the 5-10 yr range. I bought my trailer in 2011 and have done a lot of work on it over the years. So consider this a long term test. I will post some before and after photos around some windows where I used Trempro as soon as I get a chance.

For wheel wells/underbody:

Vulkem 116
Trempro 635

Roof

Silkaflex 721 White

Windows/Trim

Silkaflex 221 Gray
Parbond Gray or Clear

Small seams (between aluminum panels)

Acryl-R
Hi Gang is this list still good to use

Yes, although I find parking to be difficult to work with because it can’t be “tooled” after it has been applied. Sikaflex is better

I prefer the dymonic 100 over the Vulcem 116.

Much easier to tool.

I'm having to replace a skylight. Do the caulks mentioned for Windows/Trim apply to the skylight?

If it’s mounted to the roof, you should be using a self leveling caulk like Dicor or Sikaflex

Thanks, when you say Sikaflex I assume you are referring to 221. As near as I can tell 721 doesn't seem to exist anymore.


Best regards,
Dan

Dan - I was referring to 721. 221 is not self leveling.

I had to patch some holes in the roof of my Sovereign where I removed one of my ceiling vents. Between the patch and the roof I used 221 and when all the bucked rivets were installed I cleaned up around the edges with mineral spirits. Then I went over the edges of the patch with Dicor self-leveling caulk. I also used Dicor around a new MaxxAir vent and new TV antenna.

Hope this helps
