Concrete Coatings for Floor Repair

Many floor applications decay through erosion and the constant wear and tear. In warehouses, storage areas, and manufacturing floors, in particular, eroded surfaces may show cracks and holes. In other cases, the damage could manifest in the lessening of resistant properties in the industrial concrete floor coatings.

When this happens, the facility is faced with several unpleasant consequences of damaged floors, such as:

1. Unlevel and low-resistant surfaces that can pose safety threats or accidents to passersby and floor occupants.

2. Unsightly floors that look dirty despite frequent cleanups.

3. Encourage the growth of harmful microorganisms that can lodge on floor cracks when left un-removed.

4. Increase the severity of floor damage when left unrepaired through time.

Industrial concrete floor coating applications require filling-up the floor cracks prior to actual application. An epoxy-based filler formulation has to be applied to level the holes and irregularities. The viscosity of the filler defines the resulting surface tension.

When the crack is deep, it is best to pour sand on the crack and making sure the crack reaches the bottom. Some applications may require that quartz have to be pre-mixed with the epoxy to fill deep cracks.

In cases when hairline cracks appear, sanding off the area after the application of industrial concrete floor coatings will remove excess coatings along the hairline and blend the edges to make the crack disappear.

When the floor has really large cracks or holes that go deep down into the foundation, no amount of industrial concrete floor coating is appropriate. There is a need to repair the floor foundation first before installing any coatings system.
