The process of eliminating an existing coating from a portal’s surface can be achieved through various methods. This involves detaching the adhered substance without causing damage to the underlying material. An example would be stripping multiple layers of colored acrylic from a wooden entry point to restore its original appearance or prepare it for a new finish.
Effective removal of pre-existing coatings allows for surface preparation and the application of new, desired finishes. This can improve the aesthetic appeal of a structure, increase the longevity of the door, and potentially uncover historical details obscured by previous layers. Historically, techniques varied from manual scraping and sanding to the utilization of early chemical strippers.
