What actually damages a coating
Coatings are damaged by three things in normal service: aggressive chemistry, abrasive mechanical action and impact. Cleaning contributes to the first two. Strong alkaline products used repeatedly at high concentration attack the surface and dull it progressively, while an over-aggressive pad grade removes the top layer along with whatever was on it.
The damage is gradual and uniform, which is why it is usually attributed to age. A coating that should hold its gloss for years instead looks tired within eighteen months, and the connection to the cleaning routine is never made. Getting the product and pad right from the outset costs nothing extra and is the single largest factor in coating life. Recording the product and pad grade in the proposal also protects the coating if the contractor changes, since the decision travels with the document.
