Tremco Fyre-Sil caulk

[onpurposeproductions]

Hello all,

Tremco Acoustical sealant is about the only option I can find locally (Toronto, Ontario, Canada) for a reasonable price ( $3 per 300ml tube, $5.75 per 850ml tube). But many have reported this stuff to be incredibly awful to work with so I've been trying to see if there's another option. The guy at my local building supply suggested Tremco Fyre-Sil caulk. It's more expensive but apparently much nicer to work with. The question of course is how it will perform as an acoustical sealant?

The following info is from the product's spec .pdf (downloadable from Tremco's website) - thoughts?;

Well,

It doesn't really much matter anymore for me - this stuff costs approx 3 times the Tremco acoustical caulk at my supplier. YIKES! I think I'll have to just suck it up and use the 'black death'.

My last experience with fire stop caulk was pretty messy. I forget the brand, but man, what a hassle just getting it to go where it was supposed to go. Another example of you get what you pay for.

Hi Wayne - thanks for the reply!

I actually bought just one tube of Tremco Acoustical caulk (sometimes lovingly referred to as 'black death' to test it out). I just applied it last night and it wasn't nearly as bad as I thought it would be. It certainly is gooey and if you're not careful you will quickly get it everywhere. I used to be a painter though, so I'm quite comfortable with a caulking gun. I'm VERY happy that I found it not too bad because any other option, including Tremco's fyre-sil, was at least three times the cost. And I estimate that I'll require at least 80 850ml tubes for my project! That translates to $450 for the 'black death' as it is!

Man, 80 tubes. Rubber gloves maybe

Okay - I've been holding my tongue so far but can't contain myself any longer........

I just simply know how to handle my caulk

Okay, now that that's out of the way - in all seriousness I'm more concerned with the inhalation of the fumes and the strain on my arms and back while applying the stuff. For the fumes I've got a respirator that I had from my days as a residential painter (though I should probably get fresh filters). Trying to get a good clean bead of caulking with this stuff really puts some serious strain on my body. The only way around that is to pace myself with the work.

I'm just so darn use to clicking a mouse all day!!
