Key point
Preparation removes unsuitable material and produces the surface required for adhesion. Existing coatings, concrete strength, contamination and moisture determine the appropriate method.
CarParkCoatings.com · Updated · Technical planning guidance
Assess the existing surface
Inspect concrete strength, laitance, contamination and coating adhesion. Establish whether the existing finish is compatible with an overlay or must be removed.
Choose the mechanical method
Grinding and shot blasting produce different profiles. Select a method that suits the substrate and specified resin build-up, with dust and noise controls appropriate to the operating site.
Inspect before coating
Check prepared areas for defects, contamination and moisture. Complete agreed repairs and confirm readiness before primer application.
Specification evidence
Request current technical data for the proposed complete system. Confirm the relevant preparation method, moisture limits, movement capability, layer build-up, surface texture, application conditions and return-to-service requirements before installation.
