Cracked, Crumbling Concrete Steps?
Damaged steps are more than an eyesore, they can be dangerous. Whether a home or a commercial property, fixing damaged steps is a priority task that needs to be done immediately. Question is, do you repair or replace? If damage is extensive, it is probably better to call a pro and replace the stairs. If, however, the major portion of the steps are sound, a repair may do the trick.
The tools you will need to fix your concrete stairs are: drill with masonry bit, hammer, wire brush, concrete trowel, scrap wood or boards, latex bonding product, concrete patching material and something to mix it in, re-rod or re-bar, an old paint brush and some heavy blocks, adhesive tape, straps or clamps to hold boards in place.
Process of Repairing Step by Step
Start by cleaning off the area completely, use the wire brush. Drill a hole, or holes, into the damaged areas to fit in re-rod to act as a connector, cut and fit the metal rod and drive it in about half way, remove all debris and dust from drilling, set up a mold for the step with concrete blocks or scrap wood to create edges of steps.
Now, mix your concrete patching and apply the adhesive agent to the area, take care to mix concrete to the right consistency. Use a trowel to apply the concrete to the damaged areas. Use an old brush to stipple the finish to match the original concrete. When done application, make sure forms are solid, cover the area with plastic if it will be exposed to any rain or moisture. Remove the plastic after twenty four hours and leave the forms in place for about a week while the concrete cures. Once you remove the forms, use the wire brush to neaten up the finish, and the project is complete.
