Concrete Grinding

Local Industry Experts in Concrete Prep

Don’t be fooled by contractors who acid etch concrete and claim that it their process is “sufficient enough” for coatings. Acid etching does not give enough profile for epoxy or polyurea coatings and also introduces water and dangerous acids to your home. Acid etching has also been denounced by all key manufacturers of floor coatings.

“Acid etching tends to produce a CSP-1 to CSP-2 profile, which is suitable for only for very thin systems, such as the low solids, solvent-based coatings of the past. Today’s ultra-high solids and solvent-free industrial, commercial and institutional resinous flooring systems tend to be much thicker, requiring CSP-3 to CSP-9 for best bond and performance; this essentially renders acid etching obsolete. Contractors look to mechanical concrete preparation, such as diamond grinding, shot-blasting and scabbling to create the higher CSPs needed.”

“NEW CONCRETE: Laitance must be removed by diamond grinding or shot blasting. On concrete that has been cured with curing compounds or has had a hard steel troweled finish, shot blasting, sandblasting or other methods of mechanical preparation will be required.”
