Repair broken edges and corners on concrete steps, curbs, slabs and walls without the use of forms with QUIKRETE Quick-Setting Cement, along with QUIKRETE Acrylic Fortifier.
When working with cement-based products, always wear eye protection and waterproof gloves.
Clean the surface of the damaged area by removing any loose material such as dirt, oil, or grease and unsound or flaking concrete.
TIP: unsound or flaking concrete can be removed by using a hammer and chisel or with a masonry grinding disk and a portable drill.
Scrub and clean the surface of the repair area with a stiff bristle brush.
Thoroughly rinse the repair area after cleaning.
Mix the Quick-Setting Cement using a margin trowel by adding 5 parts Cement to 1 part QUIKRETE Acrylic Fortifier until a lump-free, putty consistency is achieved. It is important not to add more water or Acrylic Fortifier after the material has begun to set.
TIP: if the mix is too wet, add additional Quick-Setting Cement and mix thoroughly; if the mix is too dry, add small amounts of Acrylic Fortifier sparingly.
Dampen the repair area with enough water to saturate the surface (any standing water should be removed).
Use a masonry brush to apply a thin coating of the Quick-Setting Cement and Acrylic Fortifier mixture.
Using a margin trowel, press the cement into the repair area using firm trowel pressure.
Continue to build and sculpt the Quick-Setting Cement so that the surface of the repair is above the surrounding concrete.
In about 5 to 10 minutes once the patch has become thumbprint hard, use the edge of a margin trowel to mold and shape the repair to match the contour of the surrounding concrete.
