Concrete Prep
Frequently Asked Questions
Why is concrete surface preparation so important before applying coatings?
Coatings, overlays, and flooring systems rely on mechanical and chemical adhesion to the concrete substrate. A surface contaminated with laitance, curing compounds, oil, or dust will prevent proper bonding — leading to delamination, bubbling, and premature coating failure regardless of the product quality applied.
What surface profile is needed before applying floor coatings?
The required Concrete Surface Profile (CSP) depends on the coating or overlay system being applied. Thin coatings typically require CSP 1–2, while thicker overlays and heavy-duty systems require CSP 3–5. Our Floor Grinders and Scarifiers achieve different profile levels depending on the tooling and machine used.
What contaminants need to be removed during concrete prep?
Common contaminants include curing compounds, release agents, oil and grease, adhesive residues from previous floor coverings, surface laitance, and any existing failed coatings. The prep method — grinding, scarifying, or shot blasting — should be selected based on the type and depth of contamination.
Can concrete prep equipment also be used for crack repair and joint preparation?
Yes — concrete prep often includes crack chasing, joint widening, and surface routing to prepare for repair mortars and joint fillers. For cutting work associated with concrete prep, our Concrete Saws and Diamond Blades are commonly used alongside grinding equipment.
Does Wenbro provide support for selecting the right concrete prep equipment?
