Maintenance coating’s
✨Does coating disbond from the metal substrate because of increasing thickness during maintenance coating? 🌟 Overcoating an existing coating can cause the coating to disbond. 🌟Bond strength is determines whether the original coatings is “sound” or need total removal. 🌟Depending upon the type of coating, generally, all coating tends to lose adhesion with age. 🌟One […]
