Don,

How long does this material take to  set?  Where did you buy it?  Thanks.

Regarding the Polygem Liquid Concrete Repair...I bought it from  Calbar, Inc 
in Phila 215-739-9141. It comes in various degrees of hardness when  finally 
set. Kinda like wood, lead and steel hardness. I used lead. It begins to  set 
up in about a half hour and about 4 hours to be firm. Temperature can make a  
difference. We were doing a lot in some pretty cold days (low thirties) and it  
was significantly slowed. Polygem has a pretty good web site perhaps they  
identify suppliers there. I rechecked my invoices and it was $16.60 per  
cartridge. Pricey but very, very tough stuff.
 
Incidentally, I drilled holes in marble for the legs using a 2" carbide  
tipped hole saw. I had bought two but only used one for a dozen or so holes.  
Drill as deep as you can, then chip out and drill some more. I dont know just  how 
tough a material the carbide tipped whole saws will work in but they are a  
lot cheaper than renting or buying a diamond tipped hole saw.
