   What you describe sounds like a fast-curing polyurethane adhesive. The water reacts with the glue to cure it.

   I've never heard of this application, but it sounds entirely plausible.

   J-

   Just reread your post. Your friend may have been using PL Premium construction adhesive. It is polyurethane based, and sticks very well indeed. Spritz the carpet backing, then smoosh down into the glue, flattening the bead. I'll guess you'd still need half an hour to get any strength out of it.

   Pl Premium is sold at the Home Depot, as well as at most lumber yards. It came out around 1990, and is a great product. I've used it since 1991.

   But PL preminum is not that fast.

   I know with Gorilla glue, you need to have it clamped on fastened because of the expansion.  I would imagine the PL is the same.

   The Product is called Urathene 941 From Chemrex.  You can do the same thing with PL polyurathane.  The trick is to wet the strip.  If you don't it will take 24 hours to stretch.  If you spray it you can stretch in 2 to 4 hours.  Cut your pieces in 10 inch strips to keep them from bowing and screwing up your placement.

   If i am reading right, put down a bead then wet strip, not glue, befor pressing into glue, correct.

   I like to cut a bunch of pieces of strip.  Then throw them in a bucket of water.  Then I will run a bead down the wall 15 to 20 feet.  Then place the moistened strips on the glue and wiggle them around a bit to spread the glue.  Then repeat until your floor is covered.  I prefer to glue architectural strip (2 inches wide). 

   I have only ever glued the stuff down in situations where there is hydronic infloor heating issues.  Nailing is faster but don't buy the crappy strip from Home Depot.  Go to a real floorcovering wholesaler and buy strip with 5/8ths nails.  If you ask for concrete tack strip they will sell you 11/16 prenails.  They are thinner and longer.  That is the reason people have so much trouble nailing concrete strip.  It's up to you but I can hand nail 2 to 3 times faster than I can deal with glueing.

   You should also check about removing the strips, whatever way you put them down. Concrete does vary in how hard it is, so maybe try the concrete nail strips, and if has too many nails not grabbing, switch to glue.Does anyone ever put the strips down with a powder accuated nailer?

   It's way too expensive to use a powder actuated nailer.  There are pnuematic t-nailers out there for installing concrete strip.  However in my experience they only hold 50% of the time and really crater up your concrete making it harder to hand nail.  I've had a duofast T-nailer and a spotnails t-nailer.  I was not really happy with either. 

   Just for comparison sake It takes about an hour to hand nail 400 linear feet of concrete strip on a fresh slab ( less than a year old) 

   It takes me two or three hours to glue.

   They make special drill bits @ flooring supply houses that are just 1 1/2 inch pieces of square carbide.  It is not at all like a normal concrete drill bit.  You drill your holes with a hammer drill then drop in special aluminum nails.  The nails and bits are made by Halex.  This can take all day and use 5 or six bits.

   I have a Semi auto hilti but the cost on the loads and nails would be about $40 per hundred linear feet of floor.  I can also hand nail faster than I can advance a cartrige and drop the nail.

   Carpet installation sucks sub it out.  :-)
