When a good concrete floor goes bad it can happen in many ways, as in developing small or large cracks, pitting or becoming uneven, but there is an easy fix. The causes of these cracks vary and usually have something to do with the original mixture of concrete or a shifting surface below the concrete.
It is easy to fix the small cracks in concrete with a crack sealer in a ready to mix material that you just trowel in place. It will come in either a caulk-like form or a liquid form, use the liquid form on floors and pads and the caulk-like form on the walls.
Repairing Small Cracks
- Clean out the crack with a wire brush to remove dirt and loose stones. Then wash the crack with a concrete cleaner.
- Let the surface dry completely. If the crack is deep and it’s on the floor fill it partially with sand leaving an opening 1/4 – 1/2 inch deep. Then pour in the crack sealer until it forms a layer 1/4 inch deep, let dry over night and then apply another layer, repeat until surface is flush with the floor. (if using caulk, smooth with a putty knife)
Repairing Large Cracks
- Prep floor the same as for small cracks.
- On crack about 1/2 inch deep trowel in some vinyl concrete patch mixed according to the direction on bag or pail. Trowel a 1/4 layer into the crack and if more layers are needed, let patch dry for several days before applying another layer. Trowel the final layer flush with the surface and smooth.
Material for concrete patch repair is readily available at place as Home Hardware, Lowe’s, Home Depot, and so on. This is definitely something you yourself can do quit easily, it’s a simple home fix as long as the crack is not to large.
