Armstrong VCT - Which adhesive?

[964haus]

I've read so much about VCT in the past 2 weeks (searching through here and on-line) that my head's spinning.....so....

I've got Armstong VCT waiting for installation in my shed. It's got a plywood floor and I've gone over it with a floor coating to get it really smooth. It's all ready.

My question is:
I'm not sure which adhesive to use - S-750 or S-515??

I've read that some people swear by the S-750 adhesive. Reading the fact sheets for each and it looks like the S-515 dries clear and is better suited for colder climates? The S-750 doesn't appear to dry clear and has a lower working time, but does that mean it holds the tiles better? Both seem to be OK for plywood.

As it's a shed, I want this to stick well to the plywood, but I'm totally new at this stuff so prefer something that's more 'user-friendly'.

Thoughts?

Suggestions?

Thanks [again] everyone.

Matthew.

Mattthew, I used the S-750 and it has held up very well over my concrete floor. It turns from milky to clear when ready for the tiles. This helped me at the time.
I know nothing about the S-515

What does Mr. Armstrong advise?

What does Mr. Armstrong advise?

That's part of the problem...

On the Armstrong website (as the local Home Depot staff really have no idea about the product) they list a few adhesives under the "VCT & BBT Adhesives" category.

S-750
Premium - For use with the following Installation Systems:
 Commercial Vinyl Composition Tile
 Residential Dry Back Vinyl Tile
 Primer for wood and concrete with self-adhering tile

S-515
High Moisture - For use with the following Installation Systems:
 Vinyl Composition Tile

Both dry in the same time, but the S-515's working time is 24 hrs versus 'up to 6 hours' for the S-750. The other difference that I see is that the S-515 is stable to -12 (C) but the S-750 has to be kept from freezing (while in the bucket presumably)

Trying to get real world experience - leaning towards the S-750 as I recall reading here a few guys used it as well as the suggestion above...

Thanks,
Matthew.

My flooring sub uses Tarkett spray when he does Wal Marts...they mandate it. I have asked on here if anyone has used it to no avail...stuff is like 40 bucks a can and can do 175 sq ft
I have 2 cases of it for my 1280 sq ft...will let all know how it goes down

Building on this old thread, recently used Armstrong S-515 moisture resistant adhesive. Application was a well seasoned, clean, 70 year old, poured concrete floor. We followed the directions to the letter. Selected the advertised, moisture resistant product knowing rain water occasionally enters the building. A few months later after the adhesive was cured, and the floor sealed and polished we got heavy rains. Water puddled on the floor for about 12-24 hours. The floor was destroyed! Armstrong was unresponsive to claims. Can see actual photo from our Amazon review. We are now considering Taylor 2083 adhesive which is advertised as water proof. Bet your *** we'll NEVER use another, Armstrong adhesive!

I wonder what 964haus used?
