I have a customer who has been involved in a performance claim with LVP in a commercial setting.
Some of the manufacturer's reps were giving voice to putting a coating on the floor.
My customer, who knows more than the average cleaner about the stuff questioned the technical people closely.
After he didn't accept a few "non-answers" that sort of said "maybe its ok to put finish on it, they finally said this:
"If the customer notices scuffs on the floor, they should review the cleaning products they have been using. It may be necessary to reset and clean the floor several times with just a damp mop to remove any residue. Applying a new finish is not recommended because it can replace the wear layer and alter the maintenance routine. This could also affect the warranty, as it changes the specified cleaning process. If the customer believes there is a defect with the floor, they should consider filing a claim."
