Which Sikaflex Do You Use
« on: January 29, 2009, 05:12:35 PM »
I need to get some black Sikaflex.  I have had 291, but in reading descriptions, I came across Sikaflex 291 Lot.  This is said to be almost as strong, a little slower setting, and a little more flexible.  Also 521UV looked interesting.  Any experience with these?

Need more detail of the project before we can help you.

Gerald,

That makes sense, but actually I was hoping that one would be a good compromise as an all purpose product.  There are some areas around windows and such that could use some re-sealing.  I also wanted to use it to re-enforce and fill gaps in some weather stripping around the entry door.  Since these small tasks will not use anything near an entire tube, the thought was to find the one that would be suited to the most RV applications so it will be available for the future.  I have read that 291 is most commonly use by RV repair places, but wondered whether the other two mentioned would be more adaptable.  I am not concerned with any high strength requirements like mounting siding.  Thanks

Play with some Sikaflex 1A Construction Sealant, from the building construction industry.  Get it at White-cap  or a construction supply place ...
  Super cheap ($3 per caulking gun sized tube), black
 I use it everywhere on my buses for general purpose all-around, windows, gluing things, roof caulking...basically anywhere... and it works very well.

Ditto on the 1-a, but try denatured alchahol for the cleanup, you'll like it.

If bonding metal to metal, I use 252, and you'll need the cleaner and primer.  Costs more, but worth it!
