WHAT IS SURFACE PREPARATION?
Prior to the application of any coatings or further treatment, Surface Preparation is the process of treating the surface, either mechanically or chemically. The aim is to increase the surface’s attraction to coatings and is crucial to their success.
WHAT METHODS CAN BE USED IN SURFACE PREPARATION?
Depending on the tasks that need doing and the finish desired, various methods can be used.
Scabbling: using compressed air to hammer pistons into the concrete, leaving a rough surface
Scarifying: using loosely mounted cutters to remove material by a chipping action, allowing the operator to control the depth of cut. Various styles can be achieved with interchangeable assemblies for light or heavy stock removal.
Scraping: using a rapid, hammering action to increase production on all types of floor covering removal.
Grinding: using horizontally rotating discs to level, smooth or clean concrete. They use a quick release diamond tooling and provide a smoother finish than scarifiers / scabblers.
