Even a concrete floor can get damaged, either because of the foundations’ settlement or because of the exerted traction, for example, in a car park. Whatever the cause, your Levittown handyman is here to offer you some tips on how to fix cracks in concrete floors effectively. In all honesty, this may be a more challenging DIY project, but if you have the skill, you can do it.
Follow these steps to fix cracks in concrete floors:
Remark the cracks with the hammer and chisel. This will add a little more depth and width. Also, remove the loose remains that may be in them.
Clean the entire surface with a vacuum cleaner to avoid leaving any loose residue that may hinder the adherence of the next product.
Place the masking tape at the bottom of the walls and near the repair spot to protect them from stains and splashes.
Moisten the cracks with water; use the brush to reach all corners.
Apply a repair mortar. Unlike regular mortar, a repair mortar has additives that allow it to grip on mortar or old concrete. You can also use technical mortar. To apply it, use a fine-tipped palette to reach the deepest of crevices and extend it until about 2 or 3 inches from the crack.
Once the mortar is dry, you can apply a primer for the subsequent application of the self-leveling mortar. This ensures the correct adherence of self-leveling cement on the surface of the floor.
Apply self-leveling cement. Always follow the manufacturer’s instructions regarding the proportion of the mixture. This is an essential aspect of achieving the exact consistency so that the cement flow marks the correct level. Smooth out the entire surface with a trowel and finally make a few passes all over the surface with the barbed roller. This will prevent the air bubbles from forming, which is also known to produce cracks or chips in the cement.
