Q: How do I anchor a handrail in concrete?
A: Use a masonry core drill to bore an anchoring hole for the rail post 2 inches to 4 inches deep that is at least an inch wider than the diameter of the post. Increasing the embedded depth of the post will increase its pull-out strength. Mix up some Exterior Anchoring Cement following the manufacturer’s instructions (i.e., adding about 5 parts Anchoring Cement to 1 part clean water). Use a margin trowel to thoroughly mix the material to a fluid consistency similar to syrup. The cement should be uniform and lump-free. Adjust the mix ratio to get the right consistency. (For vertical applications, add less water and mix to a heavy putty consistency.) Remove any loose debris and dampen the inside of the hole, but leave no standing water. Slowly pour the Anchoring Cement into the hole around the post to a level slightly above the surface. Allow it the cement to cure according the manufacturer’s instructions.
