Damage on concrete steps usually occurs at the leading edges of the tread or at corners.
1. Undercut and widen the broken area with a cold chisel and hammer. Remove all dirt and loose concrete and clean with Concrete & Asphalt Cleaner.
2. For repairs less than 1" deep, mix QUIKRETEŽ Concrete Acrylic Fortifier with teh Quick-Setting Cement or Sand Mix.
3. Mix 5-1/2 parts Quick-Setting Cement to 1 part liquid. Mix only enough to obtain a smooth consistency and mix no more than can be applied in 10 minutes.
4. Dampen the surface and apply the mix.
5. Allow the Quick-Setting Cement to gain its initial set (5 to 10 minutes) and then sculpt the patch by scraping and shaving with the trowel edge.
For Best Results
In hot, dry conditions, keep the patch moist for 24 hours. Cover with plastic film
Do not scupt until the Quick-Setting Cement is hard enough to retain a thumbprint.
Use forms for larger repairs or when the tread projects out from the riser.
