The Importance of Concrete Surface Preparation

Preparing concrete surfaces for coatings, overlays, stains, or repair materials is a labor-intensive task that many contractors are tempted to overlook. However, skipping this essential first step almost guarantees project failure. Whether you are working on a residential patio or an industrial warehouse, proper surface preparation is the foundation of a long-lasting finish.

Why Prepare Concrete Surfaces?

Concrete preparation is required whenever you are resurfacing old slabs to look like new or upgrading to a high-end decorative concrete finish.

Today’s advanced polymer-modified overlays offer incredible versatility:

• Thin-set applications: Applied as thin as 1/8″.

• Stamped overlays: Applied up to 3/4″ thick and stamped to mimic natural stone or wood.

• Industrial utility: Essential for floor-coating installations in commercial and institutional settings.

Achieving the Right Concrete Surface Profile (CSP)

The most critical factor for the bond strength of resurfacing materials or epoxy floor coatings is the texture of the concrete. Without the correct profile, the overlay cannot “grip” the substrate, leading to delamination and cracking.
