Proper floor preparation is a crucial step in any flooring installation. Without the right preparation, even the highest-quality flooring materials can fail to perform as expected. Floor preparation may involve surface cleaning, patching, and leveling, as well as moisture testing and other specialized procedures to ensure the substrate is ready for the new flooring. By taking the time to properly prepare the substrate, you can help ensure a smooth and long-lasting flooring installation.

In addition to proper preparation, repairs may also be necessary to ensure a successful flooring installation. This may involve patching or filling any cracks, holes, or other imperfections in the substrate. Repairs may also be needed to address any underlying issues, such as moisture or structural damage, that could impact the performance of the new flooring. By addressing repairs prior to installation, you can help ensure a smooth and problem-free flooring installation.

While proper floor preparation and repairs may add time and cost to your flooring installation, they are critical steps that can help ensure a successful outcome. Taking shortcuts or skipping these important steps may result in a subpar flooring installation that fails to meet your expectations. By working with a professional flooring contractor who understands the importance of proper preparation and repairs, you can help ensure that your new flooring will perform as expected and provide a durable and attractive surface for years to come.

Concrete Surface Preparation F.A.Q.

Answers to the questions facility owners, general contractors and homeowners ask us most often about this service.

Why can’t new flooring go directly over an existing slab?

Curing compounds, old adhesives, sealers and surface laitance prevent new flooring from bonding to the concrete beneath. Mechanical preparation, usually diamond grinding, removes these contaminants and opens the surface profile so coatings and flooring systems can achieve a high-strength bond.

Do you perform concrete moisture testing?

Yes. Excess moisture vapor is one of the most common causes of flooring failure. We test slabs before installation and can recommend moisture mitigation when readings exceed what the specified flooring system tolerates.

Can you remove old coatings, tile or mastic?

Yes. We remove failed epoxy and paint, tile, thinset and adhesive residue using diamond grinding with vacuum-shrouded dust containment, leaving a clean, properly profiled slab ready for the next flooring surface.

Do you offer prep-only scopes for general contractors and flooring companies?

Yes. General contractors and commercial flooring installers regularly bring us in for grinding, coating removal, patching, leveling and moisture testing as a standalone scope, prepared to the surface profile their flooring system requires.
