How to Place Iron Rails in Concrete Using an Epoxy Anchor
- 1). Position the handrail on the concrete steps. Place it exactly where the rail will run. Have a helper support the handrail while you mark the placement on the steps.
- 2). Equip a power drill with a masonry drill bit or a hammer drill with a masonry percussion bit. If you are using a power drill, begin with a small drill bit, then increase the size of the masonry bit and enlarge the hole as you drill.
- 3). Drill holes 1/2 inch larger than the handrail posts and 4 inches deep. Center each hole 4 inches away from the edge of the steps.
- 4). Vacuum the holes and surrounding area with a shop vacuum to remove all masonry dust and debris.
- 5). Brush a masonry epoxy-based bonding agent on the inside of the holes. Immediately fill the holes halfway with masonry epoxy. Manufacturers make epoxy expressly for masonry surfaces. Do not use other types of epoxy, as they will not hold as well.
- 6). Set the handrail posts in the epoxy. Fill the hole the rest of the way with epoxy.
- 7). Place a level on the top of the handrail to check the levelness. Make adjustments as necessary to level the rail. Place the level vertically against the handrail to check plumb. Make adjustments as needed to plumb the handrail. Epoxy sets to a hard, unmovable state in 10 to 15 minutes so make any necessary adjustments quickly.
- 8). Brace the railing to hold in place with 2-by-4 inch lumber, set at a 45-degree angle from the railing to the ground while the epoxy hardens.
