SURFACE PREPARATION

Coating performance is directly affected by surface preparation. As high as 80% of all coating failures can be directly attributed in inadequate surface preparation that affects coating adhesion. Various methods can be used depending upon surface conditions, economics, and environmental concerns. These are the basic steps we use:

• Examine the Surface - The surface should be checked for barriers such as existing sealers, curing materials, grease, oil, efflorescence, and dirt that must be removed.
• Test the Concrete - A "water drop" test can be used to determine if a surface is clean. Note: New concrete must be cured at a suitable temperature for at least 28 days. We use Wagner Electronics “Rapid RH” moisture tests for testing concrete relative humidity.
• Clean Uncoated Concrete - Remove any chemicals, oil, and grease from the concrete first.
• Previously Painted Surfaces - If the paint is peeling or degrading in any way, it should be completely removed.
• Repair Surface Defects - Remove any loose concrete, and clean and fill holes, cracks and other surface defects with an approved method. Typically we V-Cut all Cracks and fill expansion joints and cracks with an elastomeric to prevent cracks from reappearing thru the new epoxy floor.
• Shot Blasting - Shot blasting is the preferred method available to create a profile for epoxy, polycrete or Methyl Methacrylate (MMA) floors to bond to. Shotblasting creates 3 times the surface profile for a seamless floor to bond to. A properly prepared surface will give the end user many years of service.
• Diamond Grinding - This method is used for the edges of the floor or open areas that require a smoother profile because of surface profile when a thin mil system is specified.
• Scarification - Scarifying is the rotary action of the cutters (toothed washers). It impacts the surface at a right angle to fracture or pulverize the top surface of the concrete to expose a clean, fresh surface.
