3M ScotchWeld DP 8010 and the second is almost the same but with a filler added -- DP 8010NS. 3M can tell you who sells it in your area. Each package runs about $20. It has a 6 month shelf life -- check the date on your product.
Tips on using it:
This is a 10:1 mixing ratio. You don't need the expensive special dispenser or mixer they might try to sell you. Get two different diameter dowels to use as plungers. Pre-mark the dowels to dispense about 1/2 batch at a time. Mix well with a stick.
Prep: medium sand the columns and the base around the columns. Clean everything with alcohol and let it dry.
You'll have about 5 minutes working time (they say 10 -- don't believe it). Have everything figured out and prepped before mixing. Applied with double latex gloved fingers . Apply by feel but keep a mirror to inspect your work. Be in a ventilated or open area. Do a practice run before mixing.
