Why Surface Prep is Critical
Properly preparing your concrete is the first and most important step in achieving a durable, long-lasting coating. Without proper preparation, even the best coatings can fail. In fact, a strong bond starts with a clean, rough, and dry surface. Therefore, this guide will walk you through the essential steps to prepare concrete for coating, ensuring the best possible results.
Step 1: Clean the Surface
The first step in preparing concrete for coating is to clean the surface thoroughly. To begin, use degreasers or mechanical scrubbers to remove dust, grease, and old paint. Any residue left behind will weaken adhesion and compromise the durability of the coating. As a result, a clean surface is crucial for ensuring that the coating bonds properly.
Step 2: Repair Cracks and Imperfections
After cleaning the surface, the next step is to repair any cracks or imperfections in the concrete. For example, use high-quality patching compounds to fill in cracks and level uneven areas. Smooth, even repairs are essential for a uniform coating thickness. Consequently, this ensures a consistent finish and prevents defects that could arise later.
Step 3: Profile the Surface
Diamond Grinding
This is the most reliable method for preparing concrete for coating. It opens the pores in the concrete and creates a rough texture, providing an excellent surface for the coating to bond with.
Shot Blasting
This method is best suited for larger commercial areas where heavy-duty prep is required. In addition, shot blasting also creates a uniform rough texture that is ideal for bonding.
Step 4: Test for Moisture
Utah’s cold seasons can trap moisture beneath the slab. Perform a moisture vapor test to ensure the surface is dry enough to coat.
Step 5: Apply the Primer
A primer is essential when preparing concrete for coating. This step is important because primers improve adhesion and extend the life of the coating. Primers are especially beneficial for porous or older concrete surfaces, as they create a stronger bond between the concrete and the coating, ensuring better performance over time.
Step 6: Final Inspection
Check for dust, cracks, or inconsistencies before applying the topcoat.
