Repair Cracked Concrete Steps
Give outdoor stairs a makeover and a safety upgrade for only $100.
Concrete steps crack and break up over time as weather extremes cause expansion and contraction. Water can also seep in and freeze, deteriorating the edges.
Once the breakup starts, it spreads and gradually gets worse, making the steps unattractive and unsafe.
The best way to fix concrete steps is to demolish them and pour new ones. Replacement is the only real option for steps that have sunk out of level or cracked all the way through.
But if the steps have only surface damage, you can save lots of cash and effort by resurfacing and recapping.
Resurface steps with minor holes, cracks and spalling and recap any with more extensive damage. Both types of repair must be painted over.
To recap, cut away the damaged areas and rebuild them using concrete.
Mix Bondall Bondcrete with water in a 4:1 ratio and apply to the surface of the old concrete. Top the steps with new concrete using Bondcrete and water in a 1:10 ratio to make the mix.
Allow a day for the repair and half a day to paint the steps for uniformity after the concrete has cured.
TIP Cutting concrete creates dust and flying chips so wear protective gear.
Clean step surfaces of wax, grease or loose contaminating materials then mix repair mortar with water. Spread mortar over the step with a brush, using a trowel to smooth and sponge to finish. Allow to dry then paint.
