Concrete preparation

Surface Preparation

A dependable floor starts with sound concrete.

What happens beneath the finished surface matters. Dust, weak concrete, old coatings and contamination can prevent a new flooring system from bonding properly, even when the finish looks good on installation day.

East Coast Coatings provides mechanical surface preparation for new construction, renovations and flooring replacement. We select the preparation method around the condition of the existing concrete and the requirements of the system being installed.

Preparation matched to the project

Shot blasting

Removes surface material using recyclable steel abrasive, creating a textured profile for compatible coatings, membranes and resinous flooring. Connected dust-collection equipment captures debris during the process.

Diamond grinding

Provides controlled removal of existing coatings, adhesive residues and surface irregularities. It is also useful for detailed preparation around edges, columns and areas larger equipment cannot reach.

Scarifying

Is used when the project requires more aggressive removal or profiling. Additional preparation may be required afterward to achieve a sound surface suitable for the final flooring system.

More than a clean-looking surface

A floor can look clean and still be unsuitable for coating. Preparation planning should account for the concrete's soundness, existing treatments, contamination, moisture condition and required surface profile. Cracks, damaged areas, joints and transitions also need appropriate attention before the finish is applied.

Our dust-controlled equipment helps manage preparation debris, while access, containment and protection requirements are coordinated around the facility. Work in sensitive or operating environments requires project-specific planning, not an assumption that preparation produces no dust.

Does new concrete still need preparation?

Yes. New concrete may have laitance, curing compounds or a tightly finished surface that interferes with adhesion. Its moisture condition must also be suitable for the selected system. New does not automatically mean ready to coat.
