How to Repair a Concrete Slab
Concrete is used for many purposes including basement floors, driveways, sidewalks and patios. It is typically revered for its strength and durability; howeve, damage does still occur. Exposure to the elements and human error are both common causes for repair.
Supplies Needed:
- Hammer and chisel, if necessary
- Injectable epoxy or concrete mix, depending on size of crack or damage
- Trowel
- Sealant, if desired
Directions for Repair:
- Remove larger pieces of concrete, if any, from the damaged area. This should be easily accomplished with a chisel and hammer.
- Clean the damaged area. Make sure all debris has been removed, and as much dirt and dust as possible. A vacuum works well for this task.
- Determine the type of product needed to repair the concrete. Small cracks can be easily filled with an injectable epoxy. Apply according to package instructions. Larger cracks will require patching with concrete. Mix according to manufacturer's directions and trowel into the damaged area. Use a feathering technique to finish off the surface area.
- Monitor the patch work. If the epoxy or concrete begins to settle, immediately add more product and use trowel to make flush with existing surface.
- Allow epoxy or concrete patch to dry completely. See product package instructions for the required curing time. Apply additional patching, if needed.
- Seal the patchwork if existing concrete has already been done. Or consider sealing the entire surface at this time. This will help protect the area in the future.
