Vulkum or Silicone??

gwsullivan · 08-28-2002, 01:40 PM

I have found several threads addressing the installation of Fantastic fans but I can not find any information on the type of sealer they used. Vulkum, Silicone or some other product?
Thanks in advance for any information.

Jerry,
The sealer to use is: SIKAFLEX, Part #360180 from the A/S factory, cost is $8.15
Good luck

I have used Vulkhem for many years on my Airstream, and around the house.

It lasts extremely well, it sticks better than any silacone I have ever used.

A trick is to use a dishwashing soap and water mixture to
smooth the surface with your finger, it also causes the caulk
to "skin over quicker".

Also, once opened the tube will cure in a few weeks. To prevent this, put it in a sealed kitchen bag (I double bag mine) and then store it in a freezer, it will last for years this way. Just thaw it by
letting it sit out overnight in the sealed bag.

Your 'original question' adressed the seal used in the installation of 'Fantastic Fan'. Since I had just had two Fantastic Fans installed at the A/S Factory, I wanted to share with you the "correct" sealer info you requested.
It appears to have been a waste of time.

Never use Silicon based products on aluminum. It will turn a real nasty grey and eventually fall off, if you are lucky.

I used Sikaflex for areas on my trailer above my windows....i.e. rooftop vents;pipe vents etc.It's a lot thicker and stickier to use than Vulkem but I have been told it holds up for ages.I would not use it for skin panel seams or tiny areas.....Vulkem or Parbond worked much better for me in those applications....but I recommend Sikaflex for bigger gaps that need caulking,especially on your roof.

Ok, but where do i find some!!!!!!!!

The product is called "Sikaflex 227".It comes in a few colors.....clearly the "aluminum grey" being the one for us Airstreamers to use.

I purchased mine from:

I am in Canada,and this is a Canadian company.For a US supplier,I would do a search or go to :

www.sika.com

Should be able to locate some near you.
