How to Place Iron Rails in Concrete Using an Epoxy Anchor

Do-it-yourself handrail installation.

Handrails offer stability and support as you ascend or descend the stairs. Most local laws and ordinances require a handrail for safety reasons. Handrail anchors are the key to the safety and security the handrail will provide. A weak anchor will result in stair railing failure, which is dangerous to those using the stairs. Installing an iron handrail with an epoxy anchor results in a tightly set handrail that will offer years of reliable support.

Things You'll Need

• Power drill or hammer drill
• Masonry drill bits
• Shop vacuum
• Epoxy-based bonding agent
• Level
• 2-by-4 inch lumber

Instructions

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.

Tips & Warnings

• Wear ear protection, safety goggles and gloves while drilling masonry surfaces.

• Wear rubber or latex gloves while using epoxy.

• Check local codes to determine if your area requires an anchor-set handrail.
