Step-by-Step Instructions
Preparation
- Undercut all edges using a cold chisel and a hammer to help the new concrete bond properly.
- Drill holes strategically into the old concrete using a hammer drill and tapcon drill bit. Install tapcon screws about 1/4 to 1/2 inch below the surface of the new concrete.
- Thoroughly dust off the step using a shop vac to ensure proper bonding.
Preparation Apply Adhesive
- Apply concrete bonding adhesive liberally to the step using a paintbrush.
- Wait 2-3 hours for the adhesive to dry.
Apply Adhesive Form Creation and Placement
- Spray Pam cooking spray onto the plywood form to prevent cement sticking.
- Place the form flush against the old step, securing it with cinder blocks to ensure it’s plumb.
Form Creation and Placement Pour and Level Concrete
- Mix quick-setting cement with water according to package directions to a smooth, heavy consistency.
- Fill the form with the cement mixture, pushing it down firmly to ensure good contact with the old step.
- Use a steel trowel to smooth the edges between the new and old cement, checking for levelness with a 24-inch level. Fill low spots and scrape off high spots.
Pour and Level Concrete Form Removal and Finishing
- Remove the form and fill any voids with additional cement, smoothing with a steel trowel and checking for plumbness with a level.
- Scrape off any excess cement from the old step.
- Round the edges of the new step using an edging tool.
Form Removal and Finishing Curing and Sealing
